    Health-related quality of life among tonsillar carcinoma patients in Sweden in relation to treatment and comparison with quality of life among the population2020In: Head and Neck, ISSN 1043-3074, E-ISSN 1097-0347, Vol. 42, no 5, p. 860-872Article in journal (Refereed)
    Abstract [en]

    Background The health-related quality of life (HRQOL) of tonsillar carcinoma survivors was explored to investigate any HRQOL differences associated with tumor stage and treatment. The survivors HRQOL was also compared to reference scores from the population. Methods In this exploratory cross-sectional study patients were invited 15 months after their diagnosis and asked to answer two quality of life questionnaires (EORTC QLQ- C30, EORTC QLQ- HN35), 405 participated. Results HRQOL was associated with gender, with males scoring better than females on a few scales. Patients HRQOL was more associated with treatment than tumor stage. Patients HRQOL was worse than that in an age- and sex-matched reference group from the normal population, the largest differences were found for problems with dry mouth followed by problems with sticky saliva, senses, swallowing and appetite loss. Conclusions The tonsillar carcinoma patients had a worse HRQOL compared to the general population one year after treatment.

    Prosodiska aspekter av nonordsproduktion hos barn med cochleaimplantat och barn med språkstörning2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Prosody can be defined as the rythmic, dynamic and melodic aspects of speech. Without prosody, speech would sound monotonous and communication could be obstructed. The aim of the present study was to examine prosodic aspects of nonword repetition by children with cochlear implants and children with language impairment. Previous studies of prosody in these groups have not in detail described what kinds of errors that occur and therefore this is interesting to investigate.

    The present study is based on previously collected data of nonword repetition among a total of 41 children, all participating in previous studies. Of these children, 27 were children with language impairment aged between 4:6-7:6 years. Fourteen were children with CI aged between 3:0-13:4. The recorded data was transcribed and analyzed group wise and the mean value of the groups were calculated.

    Children with CI showed prosodic problems in nonword repetition to a greater extent than children with language impairment did. Both children with language impairment and children with CI had difficulties with number of syllables, stress, tonal word accent and quantity of vowel. However, the children with CI generally made errors to a greater extent as well as more types of errors, compared to the children with language impairment. All children with CI made some type of prosodic error whilst 11 out of 27 of the language impaired children produced all the words prosodically correct. Children who were implanted at an older age showed greater difficulties with prosody than children who were implanted at a younger age.

    Äldreriktat tal på boenden för äldre: Förekomst och karaktäristik2011Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The term elderspeak refers to the adjustments of communication towards elderly people which are similar to those made towards young children. The adjustments are made within several language domains, and are a part of the communicative environment of the elders. The subject is relatively uninvestigated, and few, if any, studies have been conducted on the subject in Sweden. Thus the aim of the present study was to investigate the possible occurrence of elderspeak, and to describe its characteristics.

    The present study is based upon five participants working at different forms of geriatric institutions. Conversations between a caregiver and a resident and conversations between a caregiver and a colleague were recorded and broadly transcribed. The recordings were cut into separate files according to the purpose of respective analysis. The study was carried out with a data-driven perspective and previously established aspects of elderspeak and child directed speech was searched for.

    The present study established that caregivers to a varying extent adjusted their communication within several language domains. The adjustments mainly took place within the prosodic domain but they also took place within the grammatical domain. Adjustments within the pragmatic domain were found to some extent, but no adjustments within the semantic domain were found. Tendencies to adjustments of the speech were present in the majority of the participants. The present study suggests the following additions to the aspects of the elderspeak phenomenon; frequent use of name, less hesitation phenomena and less frequent simultaneous speech.

    The PhonicStick: A Swedish Study: How do children age 5 and 6 handle the PhonicStick and will the use of it affect their phonological awareness?2009Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Phonological awareness is the ability to recognise, identify and manipulate components in words. Phonological awareness is an important part of the early literacy learning, although researchers disagree on how the connection arises. In the United Kingdom, synthetic phonics is a recommended way to teach literacy and the Jolly Phonics is a common approach within this method. In Sweden, mostly synthetic but also analytic methods are used for literacy teaching. The PhonicStick is developed as a communication device for impaired people and is based on the Jolly Phonics. In this study, the PhonicStick was being tested on children aged 5 and 6 years in mainstream pre-school classes to evaluate the use of it and its use for improvement of phonological awareness. The participating children were randomly divided into a test and a control group. All children were pre- and post-tested to analyse the possible improvement of parts of the phonological awareness. The test group went through three PhonicStick sessions, including different games and tests. The results from the pre- and post-tests of phonological awareness showed no significant differences between the test and control group. However, four out of five PhonicStick tests showed a significant improvement between session 1 and session 3. This shows that the children in the study were able to handle the PhonicStick after only three sessions, including remembering phonics the without visual information and producing words including two or three phonics.

    High rate of early recurrence of peritonsillar abscess among adolescents and young adults2023In: Acta Oto-Laryngologica, ISSN 0001-6489, E-ISSN 1651-2251, Vol. 143, no 7, p. 602-605Article in journal (Refereed)
    Abstract [en]

    Background: Peritonsillar abscess (PTA) can be treated with aspiration or incision for drainage, but a subsequent PTA can occur if tonsillectomy is not performed. Better understanding is needed of when tonsillectomy should be performed to avoid PTA recurrence.

    Objective: This study investigated the recurrence rate of PTA following aspiration or incision for drainage and evaluated the risk factors for recurrence.

    Methods: The medical records of 292 patients treated for PTA were reviewed. Recurrence of PTA and elective or quinsy tonsillectomy were the primary endpoints. A Cox proportional hazards regression model for PTA recurrence was constructed with sex, age, and PTA history as predictors.

    Results: Young age was the only significant predictor of PTA recurrence. Patients aged 15 to 24 years had a 30-day recurrence rate of 15.5% and a total recurrence rate of 26.6%. The total recurrence rate among patients over 30 years of age was significantly less at 4.0% (Fisher’s exact test, p <.05).

    Conclusion and Significance: Based on our results, tonsillectomy should be considered for PTA in patients between 15 and– 25 years of age and, to effectively avoid future recurrence of PTA, should be performed urgently.

    The secondary spiral lamina and its relevance in cochlear implant surgery2018In: Upsala Journal of Medical Sciences, ISSN 0300-9734, E-ISSN 2000-1967, Vol. 123, no 1, p. 9-18Article in journal (Refereed)
    Abstract [en]

    Objective: We used synchrotron radiation phase contrast imaging (SR-PCI) to study the 3D microanatomy of the basilar membrane (BM) and its attachment to the spiral ligament (SL) (with a conceivable secondary spiral lamina [SSL] or secondary spiral plate) at the round window membrane (RWM) in the human cochlea. The conception of this complex anatomy may be essential for accomplishing structural preservation at cochlear implant surgery.

    Material and methods: Sixteen freshly fixed human temporal bones were used to reproduce the BM, SL, primary and secondary osseous spiral laminae (OSL), and RWM using volume-rendering software. Confocal microscopy immunohistochemistry (IHC) was performed to analyze the molecular constituents.

    Results: SR-PCI reproduced the soft tissues including the RWM, Reissner's membrane (RM), and the BM attachment to the lateral wall (LW) in three dimensions. A variable SR-PCI contrast enhancement was recognized in the caudal part of the SL facing the scala tympani (ST). It seemed to represent a SSL allied to the basilar crest (BC). The SSL extended along the postero-superior margin of the round window (RW) and immunohistochemically expressed type II collagen.

    Conclusions: Unlike in several mammalian species, the human SSL is restricted to the most basal portion of the cochlea around the RW. It anchors the BM and may influence its hydro-mechanical properties. It could also help to shield the BM from the RW. The microanatomy should be considered at cochlear implant surgery.

    Early self-care rehabilitation of head and neck cancer patients2011In: Acta Oto-Laryngologica, ISSN 0001-6489, E-ISSN 1651-2251, Vol. 131, no 5, p. 552-61Article in journal (Refereed)
    Abstract [en]

    CONCLUSIONS: No positive effects of early preventive rehabilitation could be identified. The results do not contradict the proposition that rehabilitation based on self-care can be effective but it is important to establish evidence-based training programs and identify proper instruments for selection of patients and evaluation of intervention.

    OBJECTIVES: Patients with head and neck cancer suffer from functional impairments due to intense treatment. In this study, we investigated the effectiveness of an experimental early preventive rehabilitation using hard, objective end points in a nonselective, longitudinal, prospective cohort study.

    METHODS: In all, 190 patients were included in the program and received instructions for training before the start of treatment with the aim of reducing swallowing problems and reducing mouth opening and stiffness in the neck. A control group of 184 patients was recruited.

    RESULTS: There was no difference in weight loss and 2-year survival between the two groups. No positive effects concerning functional impairments were found in patient-reported outcome measures.

    "The terrible dryness woke me up, I had some trouble breathing" - Critical situations related to oral health asdescribed by CPAP-treated persons with obstructive sleep apnea2022In: Journal of Sleep Research, ISSN 0962-1105, E-ISSN 1365-2869, Vol. 31, no 6, article id e13670Article in journal (Refereed)
    Abstract [en]

    Continuous positive airway pressure is a common and effective treatment for obstructive sleep apnea, but adherence remains an issue. Both obstructive sleep apnea and oral diseases are associated with cardiovascular diseases, and as oral dryness contributes to treatment abandonment, oral health is of importance for this patient group. The aim was therefore to explore how persons with continuous positive airway pressure-treated obstructive sleep apnea experience situations associated with their oral health, and which actions they take to manage these. An explorative and descriptive design was adopted using the critical incident technique. Based on a purposeful selection, 18 adults with long-term experience of continuous positive airway pressure-treatment were interviewed using a semi-structured interview guide. Both negative and positive situations were described. Negative situations consisted of challenges with breathing, including mouth-breathing, choking sensations, problems with night-time and daytime oral dryness, changes in the saliva composition, and deteriorating oral health. Positive situations included experiences of reduced mouth-breathing and oral dryness. The situations were often successfully managed by mimicking daytime movements, changing sleeping position, adjusting the CPAP-device and mask, increasing oral hygiene efforts, drinking water, using a humidifier or chinstrap, or contacting their oral healthcare clinic. Long-term experience of persons with continuous positive airway pressure-treated obstructive sleep apnea regard situations and actions from everyday life. Successful management can contribute to long-term adherence and decrease negative effects on oral health. More interdisciplinary collaborations could enable identification and adequate recommendations for persons who experience negative situations during their continuous positive airway pressure treatment.

    Grammatisk språkförståelse vid fyra år - testar vi det vi tror?: En jämförande studie av två grammatiska språkförståelsetest2011Independent thesis Advanced level (degree of Master (One Year)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    Many studies have investigated the development of children's language production, yet knowledge about how and when language comprehension develops is scarce. Researchers are agreed that comprehension generally precedes production, even though some grammatical structures are produced before the child fully comprehends them. Testing language comprehension is difficult, requiring the child to perform some kind of action in order to show his or her understanding. The aim of this study is to examine two grammatical comprehension tests, Nya SIT and TROG-2, and to compare both their content, and the results they generate. Seventy-six monolingual Swedish and bilingual 4-year-old children were tested with both tests. The conclusion is that the results of the two tests for all the children correlate fairly well, 0.7 according to Spearman's rank correlation. The correlation for the bilingual children is 0.6 and for the monolingual Swedish children 0.5. A regression analysis shows that language is the factor that has the greatest influence on the results, and that gender and age have less influence. The analysis of the test items shows that TROG-2 is a more thorough test of grammar than Nya SIT which only partly reveals the child's understanding of grammar.

    Testbatteri för talapraxi: Utformning och pilotnormering av ett artikulationstest2010Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Apraxia of speech (AOS) is a motor speech disorder that affects the planning and programming of speech, resulting in articulatory and prosodic distortions. To this date there is no available test in Swedish for assessment of AOS. Therefore, the aim of this study was to construct a test battery that enables the assessment of level of severity of the disorder, including mild AOS. A pilot standardization was performed on 50 healthy speakers. In order to determine whether the performance on the test battery is affected by sex, age or level of education, the selection of participants was stratified by these variables.

    The tasks were constructed based on previous research regarding the perceptual characteristics of AOS, taking into account also the types of tasks that have proved to be challenging for patients with AOS.

    The performance varied between different tasks of the test battery. On some tasks a high portion of the participants got very high scores, while other tasks were shown to be challenging even for healthy speakers. No significant sex differences were found on any of the tasks. However, age and level of education significantly affected the performance on some of the tasks. Overall, the effect sizes for level of education were larger than for age.

    In the future, the test battery should be able to determine the presence or absence and severity of AOS. For further development of the test battery, the standardization should continue using a larger sample. A clinical validation on patients with diagnosed AOS is also of great importance.

    Assessing eating and swallowing in adults born with intellectual and motor disabilities: Face and content validity of a Swedish translation of the Dysphagia Assessment Package2023In: Journal of Intellectual Disability Research, ISSN 0964-2633, E-ISSN 1365-2788, Vol. 67, no 11, p. 1174-1189Article in journal (Refereed)
    Abstract [en]

    Purpose: Adults born with intellectual disabilities (ID) and motor disabilities (MD) have higher risk of dysphagia and should be assessed to decrease risk of severe complications. However, standardised assessment tools in Swedish are lacking.

    Methods: The Dysphagia Assessment Package (DAP) was cross-culturally translated from English to Swedish (DAP-SE) and tested for content validity by an expert group. Face validity was assessed by five speech and language therapist (SLT) during meal observations (n = 10), and the clinical relevance was reported in a study-specific questionnaire.

    Results: The DAP-SE was culturally adapted within the process of translation and was found to contain clinically relevant aspects to assess and suggest further interventions for adults with ID and MD. Face and content validity was confirmed by the expert group.

    Conclusion: This study, in which the DAP-SE was tested in a small sample size, provides the first indications of the instrument's validity with respect to evaluating mealtimes, swallowing function and swallowing safety in adults born with ID and MD. The study adds to the knowledge on how to translate and culturally adapt an assessment tool to clinically assess dysphagia on a complex and vulnerable patient group.

    Brain Volume Differences Associated With Hearing Impairment in Adults2018In: TRENDS IN HEARING, ISSN 2331-2165, Vol. 22, article id 2331216518763689Article in journal (Refereed)
    Abstract [en]

    Speech comprehension depends on the successful operation of a network of brain regions. Processing of degraded speech is associated with different patterns of brain activity in comparison with that of high-quality speech. In this exploratory study, we studied whether processing degraded auditory input in daily life because of hearing impairment is associated with differences in brain volume. We compared TI-weighted structural magnetic resonance images of 17 hearing-impaired (HI) adults with those of 17 normal-hearing (NH) controls using a voxel-based morphometry analysis. HI adults were individually matched with NH adults based on age and educational level. Gray and white matter brain volumes were compared between the groups by region-of-interest analyses in structures associated with speech processing, and by whole-brain analyses. The results suggest increased gray matter volume in the right angular gyrus and decreased white matter volume in the left fusiform gyrus in HI listeners as compared with NH ones. In the HI group, there was a significant correlation between hearing acuity and cluster volume of the gray matter cluster in the right angular gyrus. This correlation supports the link between partial hearing loss and altered brain volume. The alterations in volume may reflect the operation of compensatory mechanisms that are related to decoding meaning from degraded auditory input.

    Ultrasound- and Doppler-Guided WALANT Arthroscopic Surgery for Patellar Tendinopathy with Partial Rupture in Elite Athletes-A 2-Year Follow-Up of a Prospective Case Series2024In: Medicina, ISSN 1010-660X, E-ISSN 1648-9144, Vol. 60, no 4, article id 541Article in journal (Refereed)
    Abstract [en]

    Background and Objectives: Patellar tendinopathy is difficult to treat, and when combined with partial rupture, there are additional challenges. The aim of this study was to evaluate the subjective outcome and return-to-sport status after ultrasound (US)- and colour doppler (CD)-guided wide awake local anaesthetic no tourniquet (WALANT) arthroscopic shaving in elite athletes. Material and Methods: Thirty Swedish and international elite athletes (27 males) with a long duration (&gt;1 year) of persistent painful patellar tendinopathy in 35 patellar tendons, not responding to non-surgical treatment, were included. All patients were treated with the same protocol of arthroscopic shaving, including bone removal and debridement of partial rupture, followed by at least 3 months of structured rehabilitation. The VISA-P score and a study-specific questionnaire evaluating physical activity level and subjective satisfaction with the treatment were used for evaluation. Results: At the 2-year follow-up (mean 23, range 8-38 months), 25/30 patients (29/35 tendons) were satisfied with the treatment result and had returned to their pre-injury sport. The mean VISA-P score increased from 37 (range 7-69) before surgery to 80 (range 44-100) after surgery (p &lt; 0.05). There was one drop-out (one tendon). There were no complications. Conclusions: US- and CD-guided WALANT arthroscopic shaving for persistent painful patellar tendinopathy, including bone removal and debridement of partial rupture, followed by structured rehabilitation showed good clinical results in the majority of the elite-level athletes.

    Splenius capitis: sensitive target for the cVEMP in older and neurodegenerative patients2019In: European Archives of Oto-Rhino-Laryngology, ISSN 0937-4477, E-ISSN 1434-4726, Vol. 276, no 11, p. 2991-3003Article in journal (Refereed)
    Abstract [en]

    Background The vestibular evoked myogenic potential (VEMP) is a technique used to assess vestibular function. Cervical VEMPs (cVEMPs) are obtained conventionally from the sternocleidomastoid (SCM) muscle; however, the dorsal neck muscle splenius capitis (SPL) has also been shown to be a reliable target alongside the SCM in young subjects. Objective This study aimed to compare cVEMPs from the SCM and SPL in two positions across young, older, and Parkinsons disease (PD) patients. Method Experiments were carried out using surface EMG electrodes placed over the SCM and SPL. cVEMPs were measured using a 30 s, 126 dB sound stimulus with 222 individual tone bursts, while subjects were in a supine and head-turned posture (also known as the head elevation method), and in a seated head-turned posture. Results When comparing cVEMPs across positions, the incidence of supine and seated SCM-cVEMPs diminished significantly in older and PD patients in comparison with young subjects. However, no statistically significant differences in incidences were found in seated SPL-cVEMPs when comparing young, older and PD patients. SPL-cVEMPs were present significantly more often than seated SCM-cVEMPs in PD patients. Conclusions SPL-cVEMPs are not altered to the same extent that SCM-cVEMPs are by aging and disease and its addition to cVEMP testing may reduce false-positive tests for vestibulopathy.

    Predicting EEG Responses to Attended Speech via Deep Neural Networks for Speech2023In: 2023 45TH ANNUAL INTERNATIONAL CONFERENCE OF THE IEEE ENGINEERING IN MEDICINE & BIOLOGY SOCIETY, EMBC, IEEE , 2023Conference paper (Refereed)
    Abstract [en]

    Attending to the speech stream of interest in multi-talker environments can be a challenging task, particularly for listeners with hearing impairment. Research suggests that neural responses assessed with electroencephalography (EEG) are modulated by listener's auditory attention, revealing selective neural tracking (NT) of the attended speech. NT methods mostly rely on hand-engineered acoustic and linguistic speech features to predict the neural response. Only recently, deep neural network (DNN) models without specific linguistic information have been used to extract speech features for NT, demonstrating that speech features in hierarchical DNN layers can predict neural responses throughout the auditory pathway. In this study, we go one step further to investigate the suitability of similar DNN models for speech to predict neural responses to competing speech observed in EEG. We recorded EEG data using a 64-channel acquisition system from 17 listeners with normal hearing instructed to attend to one of two competing talkers. Our data revealed that EEG responses are significantly better predicted by DNN-extracted speech features than by hand-engineered acoustic features. Furthermore, analysis of hierarchical DNN layers showed that early layers yielded the highest predictions. Moreover, we found a significant increase in auditory attention classification accuracies with the use of DNN-extracted speech features over the use of hand-engineered acoustic features. These findings open a new avenue for development of new NT measures to evaluate and further advance hearing technology.

    DECODING AUDITORY ATTENTION FROM EEG DATA USING CEPSTRAL ANALYSIS2023In: 2023 IEEE INTERNATIONAL CONFERENCE ON ACOUSTICS, SPEECH, AND SIGNAL PROCESSING WORKSHOPS, ICASSPW, IEEE , 2023, article id 6844Conference paper (Refereed)
    Abstract [en]

    Recent studies of selective auditory attention have demonstrated that neural responses recorded with electroencephalogram (EEG) can be decoded to classify the attended talker in everyday multitalker cocktail-party environments. This is generally referred to as the auditory attention decoding (AAD) and could lead to a breakthrough for the next-generation of hearing aids (HAs) to have the ability to be cognitively controlled. The aim of this paper is to investigate whether cepstral analysis can be used as a more robust mapping between speech and EEG. Our preliminary analysis revealed an average AAD accuracy of 96%. Moreover, we observed a significant increase in auditory attention classification accuracies with our approach over the use of traditional AAD methods (7% absolute increase). Overall, our exploratory study could open a new avenue for developing new AAD methods to further advance hearing technology. We recognize that additional research is needed to elucidate the full potential of cepstral analysis for AAD.

    The Supratarsal Approach for Correction of Anterior Frontal Bone Fractures2018In: The Journal of Craniofacial Surgery, ISSN 1049-2275, E-ISSN 1536-3732, Vol. 29, no 7, p. 1906-1909Article in journal (Refereed)
    Abstract [en]

    Background: 

    To approach isolated anterior frontal bone fracture, coronal incision is the common surgical access of choice. This approach has complications such as aesthetically undesirable scarring and alopecia along the incision line. An alternative approach to these fractures is through a supratarsal incision. The aim of the present study was to correct the frontal bone fracture, through supratarsal approach.

    Methods: 

    Six consecutive patients with frontal bone fracture were operated through supratarsal incision and evaluated regarding: patient cosmetic satisfaction, forehead contour, scarring, sensibility and motility in forehead and upper eyelids.

    Results: 

    Seven months (6–12) postoperatively, all the patients had normal mobility in the forehead and the upper eyelids and 17% (n = 1) had hypoesthesia of superior orbital nerve. The forehead contour was excellent in all patients. About 83% (n = 5) of the patients were very satisfied and 17% (n = 1) were satisfied with the surgical result.

    Conclusion: 

    Correction of anterior frontal bone fracture through a supratarsal approach appears to be safe and offers a sufficient exposure to the frontal bone fracture correction with excellent contouring results and no noticeable scarring.

    Normering av Rösthandikappindex och Halsskalan för personer över 65 år i Sverige.2012Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The population over 65 years of age is increasing and health in elderly has been a subject of research for decades but voice function and vocal health has not been prioritized. The purpose of this study is to obtain reference value for the Swedish version of Voice Handicap Index (RHI) and the Throat Scale among people over 65 years of age and assess voice function and vocal health for this age group. The questions were as followed:

    1) What is the reference value of RHI for people over 65 years of age? 2) What is the reference value of the Throat Scale for people over 65 years of age? 3) Is there a correlation between a self-rated VA-scale on the perceived degree of voice problems, and the self-rated RHI-/Throat Scale result? 4) Does age, gender or previous profession matter for the self-perceived voice?

    In total 100 individuals participated in the study, 50 women and 50 men, between 65 and 92 years old. The reference value of RHI for people over 65 years of age was 13,4 points and the reference value for the Throat Scale was 7,7 points. Both reference values are higher than reference values for younger people. The reference value of RHI is mainly described from the high points of the participants over 85 years of age. There was a correlation between the results of the RHI/the Throat Scale and the VA-scale concerning the perceived degree of voice problems, p < .01. Age is a significant factor for self-perceived voice problems. The older the subject, the higher points scored, both on the RHI, p < .05 and the Throat Scale. The results of the Throat Scale, however, were not significant. Even though most of the participants were active the reference value of RHI and the Throat Scale was higher than the reference value for younger people. The conclusion is that the voice changes in elderly affect voice experience.

    Ordförråd på modersmål hos barn i förskoleklass i Sverige: en jämförelse mellan tvåspråkiga och enspråkiga barn2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I samhället kommer vi ofta i kontakt med tvåspråkighet, så även på logopedmottagningar runt om i landet. Det kan vara svårt att genomföra språkbedömningar på barn med flera modersmål eller annat modersmål än svenska. Syftet med uppsatsen var att översätta benämningstestet "Ordracet" till arabiska och sedan använda det för att testa aktivt ordförråd. Passivt ordförråd testades med Peabody Picture Vocabulary Test III. Fonologiskt och semantiskt ordflöde testades med ordflödestestet FAS. Frågeställningarna var: Hur skiljer sig de två ordförråden hos simultant tvåspråkiga barn från ordförrådet hos enspråkiga barn? Hur skiljer sig det svenska ordförrådet från det arabiska ordförrådet inom gruppen tvåspråkiga barn? Hur ser sambandet mellan fonologiskt och semantiskt ordflöde och ordförråd ut? De tvåspråkiga barnen hade lägre resultat på arabiska än vad de enspråkiga barnen hade på svenska, både vad gäller förståelse och produktion. På svenska presterade de tvåspråkiga barnen praktiskt taget lika högt som de enspråkiga, de var alltså bättre på svenska än på arabiska. Det fanns en stor skillnad mellan grupperna på delen fonologi svenska, där de tvåspråkiga barnen fick signifikant högre resultat än de enspråkiga barnen.

    Adherence to Swedish guidelines for pain treatment in relation to pediatric tonsil surgery: A survey of the multidisciplinary team2017In: International Journal of Pediatric Otorhinolaryngology, ISSN 0165-5876, E-ISSN 1872-8464, Vol. 101, p. 123-131Article in journal (Refereed)
    Abstract [en]

    Background: Pain management in children after tonsil surgery is essential, and optimal pain treatment has been discussed for many years. Data from the National Tonsil Register in Sweden (NTRS) and a national mapping system have demonstrated the need for national pain treatment guidelines for pediatric tonsil surgery. As a result, Swedish national guidelines, together with updated patient information on the website tonsilloperation.se, were developed and implemented in 2013.

    Objectives The objective of this study was to evaluate the professionals’ opinions of and adherence to pain treatment guidelines for pediatric tonsil surgery patients in a two-year follow-up.

    Method: This descriptive cross-sectional study was based on data from an inter-professional questionnaire, which was validated by an expert group using a content validity index (S-CVI 0.93). The questionnaire was sent to all Swedish ear, nose and throat (ENT) departments (n=49) that the NTRS identified as performing tonsil surgery on children younger than 18 years of age. In each clinic, we asked for responses from staff in each of the following professions: ENT physicians, anesthesia physicians, registered nurse anesthetists, and registered nurses in the ENT departments.

    Results: Respondents from 48 ENT departments participated, and 139/163 (85%) completed questionnaires were returned. The guidelines were reported as being clear, ensuring patient safety and providing optimal pharmacological treatment. Treatment was given according to the guidelines: Half of the departments gave pre- or intraoperative treatment with clonidine, betamethasone and high-dose paracetamol (acetaminophen). A multimodal pain approach (paracetamol and COX inhibitors) after hospital discharge was prescribed by all departments after tonsillectomy and, more extensively, after tonsillotomy. One-third of the departments prescribed paracetamol with a higher normal dose for the first three postoperative days. Half of the departments prescribed rescue analgesics, clonidine or opioids after tonsillectomy. None of the departments prescribed codeine or tramadol, drugs that are discouraged in the guidelines. The majority of the departments used the website tonsilloperation.se to provide information to the patients and their caregivers.

    Conclusion: The respondents' opinions of and the ENT departments adherence to the Swedish national guidelines were considered to be good. The national implementation process in Sweden has impacted the manner in which ENT departments treat pain after tonsil surgery.

    Adherence to Swedish Guidelines for Pain Treatment in Tonsil Surgery in Pediatric Patients2016Conference paper (Refereed)
    Abstract [en]

    Objective: As shown by data from the National Tonsil Surgery Register in Sweden, tonsil surgery often causes severe pain that lasts for many days. The register data demonstrate the necessity for better evidence-based pain treatment guidelines for tonsil surgery. The guidelines, introduced in 2013, consist of both pharmacological and non-pharmacological recommendations. In the guidelines, a multimodal analgesic approach and combination of analgesics are recommended to provide effective pain treatment with limited side effects. Two national multi-professional education days on pain, pharmacology and the guidelines were offered. Web-based information about pharmacological treatment (www.tonsililloperation.se) was designed for patients and next-of-kin. The current aims were to describe adherence to the Swedish guidelines for pain treatment in tonsil surgery in pediatric patients < 18 years

    Method: An inter-professional questionnaire was developed, including questions linked to the relevant guidelines. The questions came from a national mapping before the guidelines were designed. The items were discussed by an expert group, and content validity was evaluated using the content validity index.ENT-and anesthesia physicians and nurses from all 50 ENT clinics in Sweden were enrolled.

    Results: Most clinics had received the guidelines, but there was a discrepancy between the professions. More than half had perused the literature review performed before the guidelines were designed, and attended themulti-professional education day. Pre- and perioperative treatment usually included paracetamol, clonidine and betamethasone. A multimodal pain approach after discharge from hospital (tonsillectomy and tonsillotomy) was used, combining paracetamol with cox-inhibitors. Most clinics used paracetamol, with a higher dose for the first 3 days (healthy children and acceptable nutrition), and a reduced dose from day 4.In case of inadequate analgesia after tonsillectomy, oral clonidine or opioids were used. Several clinics followed the recommendation to use clonidine as first choice and secondly an opioid. No respondents prescribed codeine compared to 80% at the mapping before the guidelines were designed. The guidelines were experienced as clear, safe and sufficient. The web-based information was used by most of the clinics to improve quality of care and provide facilitating tools for patients, relatives and caregivers.

    Conclusion: Swedish guidelines for tonsil surgery provide practical evidence-based pain treatment recommendations. To achieve a change, multi-professional education is necessary. This needs to be repeated for a wider spread.

    Future research should include evaluation through pain diaries and questionnaires to next-of-kin and children. There should be matching of data from the quality registers at each clinic, with pain variables such as unplanned health care contacts due to pain, number of days with analgesics, and return to normal diet

    Postoperative pain, pain management, and recovery at home after pediatric tonsil surgery2021In: European Archives of Oto-Rhino-Laryngology, ISSN 0937-4477, E-ISSN 1434-4726, Vol. 278, p. 451-461Article in journal (Refereed)
    Abstract [en]

    PURPOSE: To explore the severity and duration of postoperative pain, the management of analgesics, and postoperative recovery in children undergoing tonsil surgery.

    METHOD: Participants included 299 children aged 4-17 years undergoing tonsillotomy ± adenoidectomy (TT ± A) or tonsillectomy ± adenoidectomy (TE ± A). Data were collected up to 12 days. The child rated pain on the Face Pain Scale-Revised (FPS-R) and recovery using the Postoperative Recovery in Children (PRiC) questionnaire. Caregivers assessed their child's pain, anxiety, and nausea on a numeric analog scale and kept a log of analgesic administration.

    RESULTS: High pain levels (FPS-R ≥ 4) were reported in all surgical and age groups (TT ± A age 4-11, TE ± A age 4-11, TE ± A age 12-17), but there were variations in pain intensity and duration within and between groups. The TE ± A group scored more days with moderate to very excruciating pain and lower recovery than the TT ± A group, with the worst outcomes reported by older TE ± A children. The majority of the children used paracetamol + COX-inhibitors at home, but regular administration of analgesics was lacking, particularly during late evening and at night. Few were received rescue medication (opioid or clonidine) despite severe pain. Physical symptoms and daily life activities were affected during the recovery period. There was moderate agreement between child and the caregiver's pain assessment scores.

    CONCLUSION: Children reported a troublesome recovery with significant postoperative pain, particularly older children undergoing tonsillectomy. Pain treatment at home was suboptimal and lacked regular analgesic administration. Patient information needs to be improved regarding the importance of regular administration of analgesics and rescue medication.

    Patient reported outcome of pain after tonsil surgery: An analysis of 32,225 children from the National Tonsil Surgery Register in Sweden 2009-20162017Conference paper (Refereed)
    Abstract [en]

    Tonsil surgery is common surgical procedure in children and cause significant pain under postoperative recovery. The objective of this register study was to explore factors affecting pain after pediatric tonsil surgery, using patient-reported outcomes from questionnaires in the National Tonsil Surgery Registry in Sweden, 30 days after surgery. A total of 32,225 tonsil surgeries on children (aged 1-18 years) during January 2009- November 2016 were included; 13,904 tonsillectomies with or without adenoidectomy (TE±A) and 18,321 tonsillotomies with or without adenoidectomy (TT±A). In surgery cases of indication obstruction, the TT±A stopped taking painkillers and returned to normal eating habits sooner, and had less contact with health care services due to pain, compared to TE±A. After TE±A, the indication infection group had more days on analgesics and more contacts with health care services due to pain, compared to the indication obstruction group. TE±A with cold-dissection technique resulted in fewer days on painkillers compared to warm-technique, and reduced the number of contacts with health care services due to pain. Older children were affected by more days of morbidity than the younger ones, but there was no gender difference after adjustment for age, dissection technique and hemostasis technique. Implementation of national guidelines for pain treatment (2013) and patient information on the website tonsilloperation.se seems to have increased the days on analgesics after surgery. Pain after tonsil surgery depends on the surgical procedure and technique, as well as factors such as the patient’s age and surgical indication. More studies including pain interventions are needed to improve the care of tonsillectomy patients.

    Patient reported pain-related outcome measures after tonsil surgery: an analysis of 32,225 children from the National Tonsil Surgery Register in Sweden 2009–20162017In: European Archives of Oto-Rhino-Laryngology, ISSN 0937-4477, E-ISSN 1434-4726, Vol. 274, no 10, p. 3711-3722Article in journal (Refereed)
    Abstract [en]

    The objective of this study was to describe factors affecting pain after pediatric tonsil surgery, using patient reported pain-related outcome measures (pain-PROMs) from the National Tonsil Surgery Register in Sweden. In total, 32,225 tonsil surgeries on children (1 to\18 years) during 2009–2016 were included; 13,904 tonsillectomies with or without adenoidectomy (TE ± A), and 18,321 tonsillotomies with or without adenoidectomy (TT ± A). Adjustments were made for variables included in the register to compensate for contributable factors in the analysis. When compared to TE ± A for surgical indication obstruction, TT ± A resulted in lower pain-PROMs, shorter use of postoperative analgesics, earlier return to regular food intake, and lower risk for contact with health care services due to pain. Children who underwent TE ± A because of obstruction problems stopped taking painkillers and returned to normal eating habits sooner, compared to children who underwent TE ± A for infectious indications. In both indication groups, TE ± A performed with hot rather than cold technique (dissection and haemostasis) generally resulted in higher pain-PROMs. Older children reported more days on analgesics and a later return to regular food intake after TE ± A than younger ones. No clinically relevant difference between sexes was found. Between 2012 and 2016 (pre-and post-implementation of Swedish national guidelines for pain treatment), the mean duration of postoperative analgesic use had increased. In conclusion, TE ± A caused considerably higher ratings of pain-related outcome measures, compared to TT ± A. For TE ± A, cold surgical techniques (dissection and haemostasis) were superior to hot techniques in terms of pain-PROMs. Older children reported higher pain-PROMs after TE ± A than younger ones.

    Stuttering and sensory gating: a study of acoustic startle prepulse inhibition2006In: Brain and Language, ISSN 0093-934X, E-ISSN 1090-2155, Vol. 97, no 3, p. 317-321Article in journal (Refereed)
    Abstract [en]

    It was hypothesized that stuttering may be related to impaired sensory gating, leading to overflow of superfluous disturbing auditory feedback and breakdown of the speech sequence. This hypothesis was tested using the acoustic startle prepulse inhibition (PPI) paradigm. A group of 22 adults with developmental stuttering were compared with controls regarding the degree of PPI. No significant differences were found between the stuttering adults and the control group; the groups showed similar means and distribution. Likewise, no relation between the degree of PPI and the effect of altered auditory feedback on stuttering was found. In summary, the results of the study indicate that there is no relation between stuttering and PPI.

    Effect of maximally relaxed lying posture on the severity of stuttering in young adults who stutter2021In: Motor Control, ISSN 1087-1640, E-ISSN 1543-2696, Vol. 25, no 2, p. 337-347Article in journal (Refereed)
    Abstract [en]

    The current study was carried out with the aim of investigating the effect of maximally relaxed lying posture on disfluencies in young adults who stutter. A total of 24 participants (17 males, seven females; mean age = 24.9 ± 6.2 years) with developmental stuttering were a part of the study. The participants were asked to perform spontaneous speaking and reading aloud tasks in standard sitting and maximally relaxed lying postures. The severity of stuttering for the studied postures was estimated by using the Stuttering Severity Instrument. The results on the Stuttering Severity Instrument showed that stuttering parameters improved during the maximally relaxed lying posture compared with the standard sitting position. The results are discussed in the light of motor control concepts. It is concluded that the maximally relaxed lying posture can facilitate improvement in stuttering scores during spontaneous speaking as well as reading aloud in young adults who stutter. Reduced stuttering scores in the maximally relaxed lying posture suggest that speech therapists can position participants in this position while treating people who stutter.

    Micro-particle deposition in maxillary sinus for various sizes of opening in a virtual endoscopic surgery2023In: Experimental and Computational Multiphase Flow, ISSN 2661-8869, Vol. 5, no 3, p. 262-271Article in journal (Refereed)
    Abstract [en]

    Treatment of sinusitis by surgical procedures is recommended only when medication therapies fail to relieve sinusitis symptoms. In this study, a realistic 3D model of the human upper airway system was constructed based on CT images of an adult male and three different virtual functional endoscopic sinus surgeries (FESS), including only uncinectomy and uncinectomy with two different sizes of Middle Meatal Antrostomy (MMA) performed on that model. Airflow and deposition of micro-particles in the range of 1–30 µm were numerically simulated in the postoperative cases for rest and moderate activity breathing conditions. The results showed that the uncinate process alone protects the maxillary sinus well against the entry of micro-particles, and its removal by uncinectomy allows particles to deposit on the sinus wall easily. Generally, uncinectomy with a degree of MMA increases the number of deposited particles in the maxillary sinuses compared to uncinectomy surgery alone. In the studied models, the highest particle deposition in the maxillary sinuses occurred among particles with a diameter of 10–20 µm. Also, if a person inhales particles during rest breathing conditions at a low respiratory rate, the number of particles deposited in the sinuses increases. [Figure not available: see fulltext.]

    Tinnitus2007In: Nordisk Lärobok i Audiologi / [ed] Stig Arlinger, Bromma: C. A. Tegnér AB , 2007, 1, p. 315-324Chapter in book (Other academic)
    Abstract [en]

    Tinnitus innebär ljudperception utan extern ljudkälla. Med objektivt tinnitus avses fysikaliskt ljud eller vibrationer som alstras i huvudet, t ex på grund av turbulent flöde i ett blodkärl nära örat eller på grund av spasmer eller tremor i öronnära muskler. Objektiv kan ofta höras genom auskultation med stetoskop eller registreras med probmikrofon i hörselgången. Subjektiv tinnitus representerar den variant då hörselupplevelsen uppstår i sinnesorganets sensorineurala delar och därmed inte kan registreras objektivt. Detta är den vanligaste formen av tinnitus och uppträder som inslag i många hörselskador med helt olika orsak: vaxpropp i hörselgången, mellanöresjukdomar såsom otoskleros, cochleära skador beroende på åldersförändringar, buller eller Meniers sjukdom, och retrocochleära skador bl a ponsvinkelåkommor.

    Pragmatisk förmåga hos barn med cochleaimplantat2010Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    A cochlear implant (CI) is a hearing device that makes it possible for individuals who are deaf or has a severe hearing impairment to receive auditory information and develop spoken language. The pragmatic ability may be affected. In short, pragmatics may be described as the study of language use in social contexts. Pragmatic ability can be seen as the result of the individual‟s behavior as well as the underlying causes.

    The aim of the present study was to describe the pragmatic ability in children with CI. An approach inspired by Conversation Analysis (CA) was used in order to highlight the various phenomena that occurred in the interaction.

    Seven children with CI participated in the study, five girls and two boys. Each conversation consisted of either a child with CI interacting with a peer, or a child with CI interacting with a parent or a teacher. A total of 14 conversations were analyzed and phenomena relevant to the study were examined. To gather further information regarding the children‟s communicative behavior, Children’s Communication Checklist was filled in by parents and teachers.

    The children who participated in the study constitute a heterogeneous group and there was no clear pattern when it comes to hearing-impairment and pragmatic ability. The result showed that children with CI used both specific and non-specific requests for clarification. It seems as if intelligibility on the sentence level may reflect how efficient the interaction turns out, as the children with high intelligibility were the ones who managed to solve misunderstandings the best in the conversations. Furthermore, the result demonstrated that the adult participants used a higher rate of specific requests for clarification in contrast to children with CI.

    Resultat av oralmotorisk och fonologisk testning: En jämförelsestudie mellan taldelen i NOT-S och kortversionen av Stora fonemtestet2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Tal är det akustiska resultatet av rörelser i talapparaten med avsikt att förmedla ett språkligt budskap (Kent, 2000). Oralmotorisk funktion är en grundläggande förutsättning för talkommunikation (Sjögreen & Lohmander, 2008). Om tal- eller oralmotoriska problem uppstår kan en tal- eller oralmotorisk diagnos ställs utifrån en utredning över dessa funktioner (McAllister, 2008). Nordiskt Orofacialt Test – Screening (NOT-S) är ett screeningmaterial som testar den oro-faciala funktionen (Bakke, Bergendal, McAllister, Sjögreen & Åsten, 2007). Materialet består av en intervju- och en undersökningsdel som är uppdelade i sex domäner vardera. En av domänerna i undersökningsdelen är tal och består av tre uppgifter A. Talar inte, B. Räkna högt till tio och C. Säg ”pataka pataka pataka”. Syftet med föreliggande studie är att undersöka om den information som erhålls i prövning med taldelen i NOT-S överensstämmer med den information som en bedömning med ett fonologiskt test ger. I studien analyserades inspelningar av 61 ljudfiler där barn i åldern 6:0-8:0 år testas med taldelen i NOT-S och kortversionen av Stora fonemtestet. Resultatet av fonemtestet transkriberades fonetiskt och utifrån dessa beräknades Percentage of Phonemes Correct. Ett gränsvärde sattes upp för att avgöra vilka som befann sig inom normalvariationen. Dessa resultat jämfördes sedan med barnens resultat på taldelen i NOT-S. Det visade sig att åtta (13,1 %) barn hamnade under gränsvärdet för normalvariation på fonemtestet vilket står i kontrast till 22 (36 %) barn som bedömdes som avvikande på NOT-S taldel enligt de fastställda kriterierna för testet. De båda delarna i NOT-S taldel fångade tillsammans upp 100 % av de som identifierades som avvikande i fonemtestet. Därutöver fångade NOT-S upp 23 % (14 barn) som inte bedömdes som avvikande i fonemtestet. Vid beräkning av taldelen i NOT-S utan den diadochokinetiska uppgiften fångades 62,5 % upp av dem som identifierades av fonemtestet. Alla de barn som fick felfria resultat på fonemtestet fick även det på NOT-S taldel. Utifrån dessa resultat bedöms NOT-S taldel och kortversionen av Stora fonemtestet inte fullt ut ge samma information om barns talavvikelser.

    Pragmatisk förmåga hos barn med hörselnedsättning: En samtalsanalytisk studie om begäran om förtydligande2010Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Different abilities are of importance to pragmatics, there among hearing. Hearing impairment can affect language development and also pragmatic ability. The aim of the present paper was to study the pragmatic ability in terms of request for clarification in children with Hearing Impairment (HI) in conversation with children with no known hearing impairment, henceforth normally hearing (NH). The present study also describes requests for clarification sequentially in detail, and also highlights points where there may be observable differences between children with and without hearing impairment. Eight conversational pairs consisting of one child with HI and one NH child were studied. Children’s Communication Checklist (CCC) was filled out by the parents and teachers of the children with HI in order to complement the description of the pragmatic ability in children with HI. Conversation Analysis was used in order to make the study of interaction as open-minded as possible. The conversation extracts were grouped according to task or non-task oriented interaction based on the activities that occurred.

    The results of the present study showed that the children with HI and NH both used non-specific and specific requests for clarification, and that these types of requests were used in both task and non-task oriented interaction. Children with HI used the non-specific request "sorry?" to greater extent in the extracts than children with NH did. In general, no differences in occurrence of specific requests were seen between children with HI and children with NH. As regards to what happened before and after requests for clarifications, no distinct differences could be established between children with HI and children with NH. In conclusion, it is not certain if and how a hearing impairment have affected the pragmatic ability, although tendencies in the conversation extracts indicated that hearing impairment sometimes affected the interaction.

    Utveckling av kognitiva färdigheter och läsförmåga hos barn med mild och måttlig hörselnedsättning i ett ettårsperspektiv2009Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The capacity to process and to remember information is a basic condition for language ability and for coming reading ability. Reading ability is strongly connected to phonological awareness, receptive vocabulary knowledge and working memory capacity. In what way hearing impairment in children affects development of cognitive skills and later on reading ability is an area that has attracted minor attention for research.

    The aim with this study was to investigate changes in cognitive skills and reading ability in children with mild or moderate hearing impairment after one year of progress and furthermore if any connections between any increases of the abilities were to be found. Comparisons were made with results from age adequate normal hearing children. Moreover prosodic ability on word-level was tested this year. Eleven Swedish children aged 7:6-10:10 years participated in this study. To illustrate progress of the abilities mentioned the SIPS computer test battery and furthermore some manually given tests for reading and prosodic abilities were used.

    The results show a developmental trend for the children with hearing impairment on tests of working memory and reading comprehension. The least degree of development was found in the area of phonological skills. The children with hearing impairment showed in general the same capacity as normal hearing children on tests for the different abilities. In the area of working memory the children with hearing impairment had significant lower results on half of the tests than age adequate normal hearing children. Several strong connections were present for children with hearing impairment this year than last year, in-between cognitive skills and reading ability. Correlation appeared between age for insertion of hearing aid and test for decoding ability. Results on tests for prosodic ability reached ceiling effect.

    Normering av test av intraoral stereognosi och tvåpunktsdiskrimination: Hos barn i åldrarna 5;6 - 7;0 år2009Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The oral sensory ability in children can be assessed through test of intraoral stereognosis and two-point discrimination. Currently, these two tests are not frequently used in clinical settings, and normative data are not always available. The aim of this study was to establish normative data for these two tests in children aged 5;6 to 7;0 years. Further, intention was to compare the results with respect to age and gender. In total 103 children participated, 49 boys and 54 girls. The participants were divided into three age-groups. The results regarding intraoral stereognosis showed significant differences between genders, where boys performed poorer than girls. Differences between two of the three age-groups could also be established. The results show that an improvement can be expected in children six years and older.

    Regarding two-point discrimination 73 of the 103 children performed perfectly. The remaining children’s scores were also consistently high. No differences between gender and age were found.

    There was no correlation between the test results of intraoral stereognosis and two-point discrimination. Therefore it would be necessary to perform both these tests in assessment, since they probably examine two separate aspects of the oral sensory ability.

    Svenska audionomers inställning gentemot kompetensutvecklingsprogram2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning:

    Audionomyrket har utvecklats från ett assisterande till ett självständigt yrke. Framsteg inom forskning berörande audiologi ställer höga krav på audionomens kompetensutveckling. Internationellt har det undersökts hur kompetensutveckling kan förbättras, genom bildandet av frivilliga eller obligatoriska kompetensutvecklingsprogram, för att ge en säker patientvård och en tillfredsställande yrkesutveckling. I Sverige ansvarar varje audionom enskilt för sin kompetensutveckling. Det finns i dagsläget inga studier som undersöker svenska audionomers inställning till att införa liknande kompetensutvecklingsprogram som finns internationellt, vilket är motivet bakom studien. Syftet är att undersöka svenska audionomers inställning kring frivilliga samt obligatoriska kompetensutvecklingsprogram med tillhörande gransknings-process för att vidareutveckla audionomprofessionen och hålla samtliga yrkesverksamma ajour med ny vetenskap. En kvantitativ metod i form av en webbenkät tillämpades för att nå ut till ett stort omfång yrkesverksamma audionomer över hela Sverige. Studiens resultat visar att ett stort antal yrkesverksamma audionomer är positivt inställda till det frivilliga samt obligatoriska kompetensutvecklingsprogrammet med tillhörande granskningsprocess. En förändrad form av kompetensutvecklingssystem än den nuvarande är därmed eftersträvad av majoriteten. Studiens resultat har tagit fasta på att kompetensutvecklingsprogram bör inriktas mot både de tvärvetenskapliga områden som professionen bygger på och audionomens specialiseringsområden. Audionomerna anser att tiden motsvarande en till åtta timmar per månad är tillräcklig för kompetensutvecklande aktiviteter. Audionomerna har en stor medvetenhet om vikten av att utveckla den professionella kompetensen. Hindrande faktorer som ekonomi, hög patientgenomströmning, tidsbrist, etc. minskar audionomernas möjlighet till deltagande av kompetensutvecklande aktiviteter. De yttre omständigheterna bidrar till att yrkesverksamma audionomer i hög grad önskar en förändrad form av kompetensutvecklings-system än den nuvarande.

    Abstract [en]

    Breathing, swallowing, chewing, facial expressions and articulation are aspects of orofacial function (Bakke, Bergendal, McAllister, Sjogreen, & Asten, 2007). Oral motor function is important for speech production as well as eating

    (Lundeborg Hammarström, 2010). The Nordic Orofacial Test –Screening (NOT-S) is a screening instrument for orofacial dysfunction (Bakke et al., 2007). The purpose of this study was to collect data about how typically developed children aged 6:0-8:0 years perform on NOT-S, and also to examine if there were any age or gender differences in the results. A total of 80 children and their caretakers participated in the study. There were 30 children aged six and 50 aged seven. The children were tested in their schools and their parents were interviewed by telephone. The results showed that children aged 6:0- 8:0 years had a mean score of 1,44 ± 1,16 on NOT-S. For children at age six the mean score was 1,63 ± 1,16 and for the children at age seven, the mean score was 1,32 ± 1,15. No significant age or gender differences were found in the results except in the interview section, where a significant gender difference between children at age seven was measured. Boys had more orofacial problems than girls. Results may be used as norm data when using the NOT-S in clinical practice.

    Voice Onset Time among Children with Phonological Impairment.2012Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Speech production requires cooperation between cognitive, linguistic and motor processes. It also requires spatial and temporal control of muscles, as well as simultaneous and coordinated activity of respiration, phonation and articulation (Cheng, Murdoch, Goozée & Scott, 2007; Yorkston, Beukelman, Strand & Bell, 1999; Raphael, Borden & Harris, 2011). Voice Onset Time (VOT) reflects the timing between phonation and articulation (Hoit-Dalgaard, Murry & Kopp, 1983). VOT is the most reliable acoustic cue for distinguishing between voiceless or voiced plosives (Auzou et al. 2000). Studies of English-speaking children with phonological impairment have shown atypical VOT-patterns (Bond & Wilson, 1980). The aim of the present study was to investigate Voice Onset Time (VOT) among Swedish children with phonological impairment and to examine if their VOT-values differ from typically developed Swedish children. Participants were 38 children aged 4;2−11;6 distributed over eight age- groups and five developmental stages of phonology. Audio recordings of minimal pairs were made at preschools, schools or at speech pathology clinics. The results indicated that children with phonological impairment produced VOT with deviant values and with a great variability. A marked acoustic difference between voiceless and voiced stop consonants was present, but not in all cases. Since the VOT-values were distributed over the group of children with phonological impairment, no developmental trend toward adult-like values that could be related to increasing age was found for either the acquisition of producing VOT or the acquisition of producing voicing lead. No differences in VOT were seen between the children in different phonological developmental stages or ages. No correlation between the degree of deviance of VOT and the proportion of Procent Phonemes Correct (PPC), age or phonological processes were found. From the results the conclusion can be drawn that children with phonological impairment have deviant VOT-values that could be caused by lack of phonological knowledge, but in particular since the variability did not decrease with increased age, have difficulties with motor execution.
