    Vocal fold collision threshold pressure: An alternative to phonation threshold pressure?2009Ingår i: Logopedics, Phoniatrics, Vocology, ISSN 1401-5439, E-ISSN 1651-2022, Vol. 34, nr 4, s. 210-217Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Phonation threshold pressure (PTP), frequently used for characterizing vocal fold properties, is often difficult to measure. This investigation analyses the lowest pressure initiating vocal fold collision (CTP). Microphone, electroglottograph (EGG), and oral pressure signals were recorded, before and after vocal warm-up, in 15 amateur singers, repeating the syllable /pa:/ at several fundamental frequencies with gradually decreasing vocal loudness. Subglottal pressure was estimated from oral pressure during the p-occlusion, using the audio and the EGG amplitudes as criteria for PTP and CTP. The coefficient of variation was mostly lower for CTP than for PTP. Both CTP and PTP tended to be higher before than after the warm-up. The results support the conclusion that CTP is a promising parameter in investigations of vocal fold characteristics.

    Differences in phonologic and prosodic abilities in children with phonological language impairment and phonological-grammatical language impairment assessed with non-word repetition2016Ingår i: Logopedics, Phoniatrics, Vocology, ISSN 1401-5439, E-ISSN 1651-2022, Vol. 41, nr 2, s. 66-76Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Prosody can be described as the rhythmic, dynamic, and melodic aspects of language. Swedish has a relatively complex prosodic system compared to, for example, English. A large percentage of Swedish children with language impairment show prosodic problems to some extent. In the present study, non-word repetition was used to assess the phonological and prosodic abilities in children with phonological language impairment and children with phonological-grammatical language impairment. In the study, 10 children with phonological language impairment and 14 children with phonological-grammatical language impairment from 4;3 to 6;2 years of age participated. All children heard the same recorded non-words and words. The group with phonological language impairment received higher scores in all variables, compared to the group with phonological-grammatical language impairment. The results showed significant differences between the groups regarding production of vowels correct in words and production of phonemes correct in non-words as well as production of unstressed syllables in non-words and production of correct stress in non-words. Percent correctly produced vowels in words, but not in non-words, correlated significantly with grammatical ability.

    Facilitating language skills through interactive microcomputer instruction: Observations on seven children with autism1993Ingår i: Logopedics, Phoniatrics, Vocology, ISSN 1401-5439, E-ISSN 1651-2022, Vol. 18, nr 1, s. 3-8Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The present study investigates whether children with autism would benefit from using an interactive and child initiated microcomputer program (ALPHA) when learning to read and write. Previous research has demonstrated strong effects when used with deaf or multihandicapped children. In this study, six children with autism used a Swedish version of ALPHA for a period of 3 to 4 months. In addition, one autistic child used the U.S. version when learning English as a second language. The results indicate strong gains in reading and phonological skills for four of the children. One child displayed a mixed pattern and two children failed to show any improvement. It is concluded that interactive micro-computer instruction may be of help for children with autism, but that mental age, motivation, and overall interest in communication must be considered when planning such interventions.

    Assessment of pragmatic language impairment in children referred to psychiatric services: A pilot study of the Children's Communication Checklist2007Ingår i: Logopedics, Phoniatrics, Vocology, ISSN 1401-5439, E-ISSN 1651-2022, Vol. 32, s. 23-30Artikel i tidskrift (Refereegranskat)
    Abstract [en]

      The aim of the present pilot study was to explore whether pragmatic language impairments are more prevalent among children referred to child psychiatric services (n=21) than among a comparison group of typically developing children (n=29) in the age range 8-10 years. A second and minor aim was also to assess the usability of a Norwegian translation of the Children's Communication Checklist (CCC). Communication disorders defined as a pragmatic score equal to or below 140 on the CCC were identified in a majority (0.57) of the children in the clinical group; the corresponding proportion for the typically developing comparison group was only 0.10. Thus, the Norwegian version of the CCC distinguishes between children with symptoms of pragmatic language impairments and those with no symptoms, as does the English version.

    Patient characteristics and intervention effect as measured by Voice Handicap Index2017Ingår i: Logopedics, Phoniatrics, Vocology, ISSN 1401-5439, E-ISSN 1651-2022, Vol. 42, nr 2, s. 93-98Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: To analyze patients with a confirmed voice disorder in order to identify patterns regarding age, gender, and occupation compared to the general public. To explore effects of voice therapy according to the Voice Handicap Index (VHI) score pre- and post-therapy in relation to the number of sessions, age, and gender. Design: Prospective cohort study. Materials and methods: This study was conducted as a collaborative project between Linkoping University and hospitals in the south-east health care region in Sweden. Six voice clinics participated by asking their patients voluntarily to complete the Swedish version of the VHI at the beginning and end of therapy. Results and conclusions: The two most prevalent diagnoses were dysphonia (43%) and phonasthenia (25%). Among the working population, the three most common occupational fields were education, health care, and child-care. The majority of the patients were women (74.3%), and the mean age of all patients was 55 years. A significant improvement in VHI scores was found after therapy, with an average decrease of 19 median points in total score and a substantial effect size (0.55). The number of sessions did not significantly correlate with the mean VHI score difference but had a weak correlation to the start and end scores. Increasing age correlated with a higher median VHI score both at the start and end of therapy but did not affect the average decrease between the two measurements.

    Influence of adenotonsillar hypertrophy on /s/-articulation in children-effects of surgery2011Ingår i: Logopedics, Phoniatrics, Vocology, ISSN 1401-5439, E-ISSN 1651-2022, Vol. 36, nr 3, s. 100-108Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Tonsillar hypertrophy is common in young children and affects several aspects of the speech such as distortions of the dento-alveolar consonants. The study objective was to assess s-articulation, perceptually and acoustically in children with tonsillar hypertrophy and compare effects of two types of surgery, total tonsillectomy and tonsillotomy. Sixty-seven children, 50-65 months, on waiting list for surgery, were randomized to tonsillectomy or tonsillotomy. The speech material was collected pre-operatively and six months post-operatively.  Two groups of age-matched children were controls. /S/-articulation was affected acoustically with lower spectral peak locations and perceptually with less distinct /s/-production before surgery, in comparison to controls.  After surgery /s/-articulation was normalized perceptually, but acoustic differences remained. No significant differences between surgical methods were found.

    Voice onset time in Swedish children and adults2012Ingår i: Logopedics, Phoniatrics, Vocology, ISSN 1401-5439, E-ISSN 1651-2022, Vol. 37, nr 3, s. 117-122Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Voice onset time (VOT) is a temporal acoustic parameter, which reflects the timing of speech motor control. The objective of the work was to obtain normative VOT data in Swedish children. Thus, 150 children aged 8-11 years old and 36 adults were audio-recorded when producing the plosives in minimal pairs. Measures were made using waveforms and spectro-grams. Results show that Swedish children developed adult-like VOT values between 9 and 10 years. By the age of 10 years prevoicing was also found to be completely adultlike in length. The results indicate that all Swedish adults do not produce voiced plosives with prevoicing. No evident gender differences were found. The obtained VOT values can be used as normative data when assessing children with speech and language disorders.

    Voice onset time in Swedish children with phonological impairment2015Ingår i: Logopedics, Phoniatrics, Vocology, ISSN 1401-5439, E-ISSN 1651-2022, Vol. 40, nr 4, s. 149-155Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Mastering spatial and temporal co-ordination in speech production is a challenge for children. Voice onset time (VOT) reflects timing in speech. The objective was to study VOT in Swedish children with a diagnosed phonological impairment and compare results with normative data. Thus 38 children, aged 4-11 years, in three age-groups were audio-recorded when producing minimal pairs with the plosives /p b t d k g/. Waveforms and spectrograms were analysed. Results show that children with phonological impairment produced plosives with deviant VOT values and greater variability compared to normative data. No developmental trend was seen with increasing age. Also, no relationship was found between VOT values and degree of impairment measured by percentage phonemes correct. Furthermore no relation was found between number of errors on auditory discrimination of nine minimal pairs with the different plosives and number of deviant VOT. Findings were interpreted as displaying motor co-ordination difficulties.

    Treatment with a combination of intra-oral sensory stimulation and electropalatography in a child with severe developmental dyspraxia2007Ingår i: Logopedics, Phoniatrics, Vocology, ISSN 1401-5439, E-ISSN 1651-2022, Vol. 32, nr 2, s. 71-9Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper describes the use of a combination of intra-oral sensory stimulation and electropalatography (EPG) in the treatment of a case with severe developmental verbal dyspraxia. A multiple-baseline design was used. The treatment duration was 11 months and started when the subject was 5 years old. The efficacy of the treatment was assessed by calculations of percentage of correctly articulated words, percentage of consonants correct, percentage of phonemes correct and percentage of words correct. Intelligibility assessments were conducted by both naïve and expert listeners. The experts also assessed visual deviances in articulatory gestures from video recordings. Qualitative analysis of EPG data was made. The subject's speech was significantly improved by the treatment in all aspects. The results and their generalization to other cases of developmental verbal dyspraxia are discussed.

    Oral motor dysfunction in children with adenotonsillar hypertrophy-effects of surgery2009Ingår i: Logopedics, Phoniatrics, Vocology, ISSN 1401-5439, E-ISSN 1651-2022, Vol. 34, nr 3, s. 111-116Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Adenotonsillar hypertrophy is associated with a wide range of problems. The enlargement causes obstructive symptoms and affects different functions such as chewing, swallowing, articulation, and voice. The objective of this study was to assess oral motor function in children with adenotonsillar hypertrophy using Nordic Orofacial Test-Screening (NOT-S) before and 6 months after surgery consisting of adenoidectomy combined with total or partial tonsil removal. A total of 67 children were assigned to either tonsillectomy (n=33) or partial tonsillectomy, 'tonsillotomy' (n=34); 76 controls were assessed with NOT-S and divided into a younger and older age group to match pre- and post-operated children. Most children in the study groups had oral motor problems prior to surgery including snoring, open mouth position, drooling, masticatory, and swallowing problems. Post-surgery oral motor function was equal to controls. Improvement was independent of surgery method.

    Spatiotemporal arrangement of objects in activities with people with dementia2019Ingår i: Logopedics, Phoniatrics, Vocology, ISSN 1401-5439, E-ISSN 1651-2022, Vol. 44, nr 1, s. 31-40Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose: This study shows how the spatial organization of objects and their use may impact locally produced order of activities and how that can affect the accomplishment of everyday activities by people with dementia. Methods: The study is based on ethnomethodological conversation analysis of eight and a half hours of video recordings in three different settings. Eighteen sequences of activities identified were multimodally transcribed and analyzed. Results: The availability or non-availability of objects, their arrangements and manipulations play a crucial role in the management of the order of activities and may present both challenges and facilitations for people with dementia. The organizations of objects directly influence the order of the activity, and the objects potential use may afford actions that deviate from the trajectory and the order of the main activity. Conclusions: One of the significant uses of objects is how they contribute to the perceptual field where attention is organized for building actions. Participants in activities modify the perceptual field by manipulating objects in the material surrounds in response to the relevancies resulting from the unfolding activities. Therefore, spatial contingency is significant in the accomplishment of activities by people with dementia. As it is not self-evident that verbal instructions may result in the instructed actions accordingly, the rearrangement of objects and making them timely available to people with dementia may increase the possibilities of keeping the order of the activities intact.

    Childhood apraxia of speech: A survey of praxis and typical speech characteristics2017Ingår i: Logopedics, Phoniatrics, Vocology, ISSN 1401-5439, E-ISSN 1651-2022, Vol. 42, nr 2, s. 84-92Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose: The purpose of this study was to investigate current knowledge of the diagnosis childhood apraxia of speech (CAS) in Sweden and compare speech characteristics and symptoms to those of earlier survey findings in mainly English-speakers. Method: In a web-based questionnaire 178 Swedish speech-language pathologists (SLPs) anonymously answered questions about their perception of typical speech characteristics for CAS. They graded own assessment skills and estimated clinical occurrence. Results: The seven top speech characteristics reported as typical for children with CAS were: inconsistent speech production (85%), sequencing difficulties (71%), oro-motor deficits (63%), vowel errors (62%), voicing errors (61%), consonant cluster deletions (54%), and prosodic disturbance (53%). Motor-programming deficits described as lack of automatization of speech movements were perceived by 82%. All listed characteristics were consistent with the American Speech-Language-Hearing Association (ASHA) consensus-based features, Strands 10-point checklist, and the diagnostic model proposed by Ozanne. The mode for clinical occurrence was 5%. Number of suspected cases of CAS in the clinical caseload was approximately one new patient/year and SLP. Conclusions: The results support and add to findings from studies of CAS in English-speaking children with similar speech characteristics regarded as typical. Possibly, these findings could contribute to cross-linguistic consensus on CAS characteristics.

    Voice disorders in children with oral motor dysfunction: Perceptual evaluation pre and post oral motor therapy2003Ingår i: Logopedics, Phoniatrics, Vocology, ISSN 1401-5439, E-ISSN 1651-2022, Vol. 28, nr 3, s. 117-125Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    A few clinical investigations of children's voices have suggested a relation between voice deviation and oral motor and sensory dysfunction. This motivated the present retrospective study of the occurrence of voice disorders in a group of children with oral motor problems. A further aim was to evaluate the effect of an oral motor and articulatory treatment programme upon voice function in this patient group. Subjects were 38 children with oral motor deficits who had received and finished therapy at the clinic. The recordings of a picture naming task, before onset of therapy and at therapy ending, were selected. The voices were presented in random order on a test tape and perceptually evaluated by an expert panel of speech pathologists. Eleven perceptual parameters were selected, based on previous investigations of children's voices. Ten of these parameters were represented by a 100 mm visual analogue scale. Register was represented by a categorical scale with the options chest, falsetto, and child voice register. The results were compared with previous investigations of child voice function. Results indicated: 1) The occurrence of voice disorders in the present group of children with oral motor difficulties was somewhat lower than in children with normal articulation. 2) Oral motor treatment also influenced and improved the perceptual impression of voice quality in this group.

    Digital communication support in interaction involving people with dementia2019Ingår i: Logopedics, Phoniatrics, Vocology, ISSN 1401-5439, E-ISSN 1651-2022, Vol. 44, nr 1, s. 41-50Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: People with dementia frequently suffer from communication disabilities, which usually influence their quality of life. The communication disabilities may affect a persons possibility to participate in interaction as a result of reduced ability to initiate new topics and difficulties in contributing new information to maintain the conversational topic. Technical aids have been proved useful to facilitate communicative activities by supporting memory and stimulating communicative initiatives. Purpose: The aim of the present study is to further understandings of how digital communication support may be used in interaction involving people with dementia. A further aim is to investigate how participants experience communication with and without the use of communication aids. Methods: The study is carried out in a Swedish context, and three dyads of older women with dementia and professional carers participated in the study. The dyads interact in the home environments of the persons with dementia using tablet computers and two web-based applications with generic pictures, videos, and music files (Computer Interactive Reminiscence and Communication Aid, CIRCA) and personalised pictures and films (Computer Interactive Reminiscence and Communication University of Sheffield, CIRCUS). The data include twenty-one video recorded activities. Results and Conclusion: The applications appear to provide support for the dyads in finding things to talk about. The participants talk both about the material and memories associated with the material. The participants experience the use of communication aids as positive.

    Clarification requests in everyday interaction involving children with cochlear implants2014Ingår i: Logopedics, Phoniatrics, Vocology, ISSN 1401-5439, E-ISSN 1651-2022, Vol. 39, nr 3, s. 130-138Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of the present study is to explore the form and function of clarification request sequences in interaction involving children with cochlear implants. Clarification request sequences are investigated in everyday interaction, and it is demonstrated that children with CI use both general/open and specific requests for clarification. It is also shown that there is relatively lower frequency of requests for clarification in interactions involving children with CI with high intelligibility scores. The results may be useful in clinical assessment and intervention demonstrating the importance of assessing interactional ability in everyday interaction.

    Assessing speech perception in Swedish school-aged children: preliminary data on the Listen-Say test2018Ingår i: Logopedics, Phoniatrics, Vocology, ISSN 1401-5439, E-ISSN 1651-2022, Vol. 43, nr 3, s. 106-119Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    To meet the need for a linguistic speech perception test in Swedish, the Listen-Say test was developed. Minimal word pairs were used as speech material to assess seven phonetic contrasts in two auditory backgrounds. In the present study, childrens speech discrimination skills in quiet and in four-talker (4T) speech background were examined. Associations with lexical-access skills and academic achievement were explored. The study included 27 school children 7-9 years of age. Overall, the children discriminated phonetic contrasts well in both conditions (quiet: Mdn 95%; 4T speech; Mdn 91% correct). A significant effect of 4T speech background was evident in three of the contrasts, connected to place of articulation, voicing and syllable complexity. Reaction times for correctly identified target words were significantly longer in the quiet condition, possibly reflecting a need for further balancing of the test order. Overall speech discrimination accuracy was moderately to highly correlated with lexical-access ability. Children identified as having high concentration ability by their teacher had the highest speech discrimination scores in both conditions followed by children identified as having high reading ability. The first wave of data collection with the Listen-Say test indicates that the test appears to be sensitive to predicted perceptual difficulties of phonetic contrasts particularly in noise. The clinical benefit of using a procedure where speech discrimination, lexical-access ability and academic achievement are taken into account is discussed as well as issues for further test refinement.
