- Background and aim: Adequate velopharyngeal function and speech are main goals in the treatment of cleft palate. The objective was to investigate if there were differences in velopharyngeal competency (VPC) and hypernasality at age 5 years in children with unilateral cleft lip and palate (UCLP) operated on with different surgical methods for primary palatal repair. A secondary aim was to estimate burden of care in terms of received additional secondary surgeries and speech therapy. Design: Three parallel group, randomised clinical trials were undertaken as an international multicentre study by 10 cleft teams in five countries: Denmark, Finland, Sweden, Norway, and the UK. Methods: Three different surgical protocols for primary palatal repair were tested against a common procedure in the total cohort of 448 children born with a non-syndromic UCLP. Speech audio and video recordings of 391 children (136 girls, 255 boys) were available and perceptually analysed. The main outcome measures were VPC and hypernasality from blinded assessments. Results: There were no statistically significant differences between the prevalences in the arms in any of the trials. VPC: Trial 1, A: 58%, B: 61%; Trial 2, A: 57%, C: 54%; Trial 3, A: 35%, D: 51%. No hypernasality: Trial 1, A: 54%, B: 44%; Trial 2, A: 47%, C: 51%; Trial 3, A: 34%, D: 49%. Conclusions: No differences were found regarding VPC and hypernasality at age 5 years after different methods for primary palatal repair. The burden of care in terms of secondary pharyngeal surgeries, number of fistulae, and speech therapy visits differed.

- BACKGROUND AND AIMS: Longstanding uncertainty surrounds the selection of surgical protocols for the closure of unilateral cleft lip and palate, and randomised trials have only rarely been performed. This paper is an introduction to three randomised trials of primary surgery for children born with complete unilateral cleft lip and palate (UCLP). It presents the protocol developed for the trials in CONSORT format, and describes the management structure that was developed to achieve the long-term engagement and commitment required to complete the project.METHOD: Ten established national or regional cleft centres participated. Lip and soft palate closure at 3-4 months, and hard palate closure at 12 months served as a common method in each trial. Trial 1 compared this with hard palate closure at 36 months. Trial 2 compared it with lip closure at 3-4 months and hard and soft palate closure at 12 months. Trial 3 compared it with lip and hard palate closure at 3-4 months and soft palate closure at 12 months. The primary outcomes were speech and dentofacial development, with a series of perioperative and longer-term secondary outcomes.RESULTS: Recruitment of 448 infants took place over a 9-year period, with 99.8% subsequent retention at 5 years.CONCLUSION: The series of reports that follow this introductory paper include comparisons at age 5 of surgical outcomes, speech outcomes, measures of dentofacial development and appearance, and parental satisfaction. The outcomes recorded and the numbers analysed for each outcome and time point are described in the series.TRIAL REGISTRATION: ISRCTN29932826.

- Background and aim: Normal articulation before school start is a main objective in cleft palate treatment. The aim was to investigate if differences exist in consonant proficiency at age 5 years between children with unilateral cleft lip and palate (UCLP) randomised to different surgical protocols for primary palatal repair. A secondary aim was to estimate burden of care in terms of received additional secondary surgeries and speech therapy. Design: Three parallel group, randomised clinical trials were undertaken as an international multicentre study by 10 cleft teams in five countries: Denmark, Finland, Norway, Sweden, and the UK. Methods: Three different surgical protocols for primary palatal repair were tested against a common procedure in the total cohort of 448 children born with non-syndromic UCLP. Speech audio- and video-recordings of 391 children (136 girls and 255 boys) were available and transcribed phonetically. The main outcome measure was Percent Consonants Correct (PCC) from blinded assessments. Results: In Trial 1, arm A showed statistically significant higher PCC scores (82%) than arm B (78%) (p=.045). No significant differences were found between prevalences in Trial 2, A: 79%, C: 82%; or Trial 3, A: 80%, D: 85%. Across all trials, girls achieved better PCC scores, excluding s-errors, than boys (91.0% and 87.5%, respectively) (p=.01). Conclusions: PCC scores were higher in arm A than B in Trial 1, whereas no differences were found between arms in Trials 2 or 3. The burden of care in terms of secondary pharyngeal surgeries, number of fistulae, and speech therapy visits differed.

- Background and aim: Few studies have explored childrens emotional and behavioural reactions to cleft surgery and treatment-related stress. The objective was to investigate parents evaluations of appearance and treatment outcomes in their 5-year-old child with unilateral cleft lip and palate (UCLP), and their perceptions of how their child was coping with treatment, comparing this information with recorded postsurgical complications.Design: Three parallel group randomised clinical trials were undertaken as an international multicentre study by 10 cleft teams in five countries: Denmark, Finland, Sweden, Norway, and the UK.Methods: Three different surgical procedures for primary palatal repair were tested against a common procedure in the total cohort of 448 children born with a non-syndromic UCLP. A total of 356 parents completed the Scandcleft Parent Questionnaire, and 346 parents completed the Cleft Evaluation Profile.Results: The results indicated that the majority of parents were satisfied with cleft-related features of their childs appearance. Further, most children coped well with treatment according to their parents. Nevertheless, 17.5% of the children showed minor or short-term reactions after treatment experiences, and 2% had major or lasting difficulties. There were no significant relationships between parent perceptions of treatment-related problems and the occurrence of post-surgical medical complications.Conclusions: Most parents reported satisfaction with their childs appearance. However, treatment-related problems were described in some children, urging cleft centres to be aware of potential negative emotional and behavioural reactions to treatment in some young children, with a view to preventing the development of more severe treatment-related anxiety.

Perceived Voice Quality and Voice-Related Problems Among Older Adults With Hearing Impairments
- 2018
-
Ingår i: Journal of Speech, Language and Hearing Research. - : AMER SPEECH-LANGUAGE-HEARING ASSOC. - 1092-4388 .- 1558-9102. ; 61:9, s. 2168-2178

Tidskriftsartikel (refereegranskat)abstract
- The auditory system helps regulate phonation. A speakers perception of their own voice is likely to be of both emotional and functional significance. Although many investigations have observed deviating voice qualities in individuals who are prelingually deaf or profoundly hearing impaired, less is known regarding how older adults with acquired hearing impairments perceive their own voice and potential voice problems. Purpose: The purpose of this study was to investigate problems relating to phonation and self-perceived voice sound quality in older adults based on hearing ability and the use of hearing aids. Method: This was a cross-sectional study, with 290 participants divided into 3 groups (matched by age and gender): (a) individuals with hearing impairments who did not use hearing aids (n = 110), (b) individuals with hearing impairments who did use hearing aids (n = 110), and (c) individuals with no hearing impairments (n = 70). All participants underwent a pure-tone audiometry exam; completed standardized questionnaires regarding their hearing, voice, and general health; and were recorded speaking in a soundproof room. Results: The hearing aid users surpassed the benchmarks for having a voice disorder on the Voice Handicap Index (VHI; Jacobson et al., 1997) at almost double the rate predicted by the Swedish normative values for their age range, although there was no significant difference in acoustical measures between any of the groups. Both groups with hearing impairments scored significantly higher on the VHI than the control group, indicating more impairment. It remains inconclusive how much hearing loss versus hearing aids separately contribute to the difference in voice problems. The total scores on the Hearing Handicap Inventory for the Elderly (Ventry amp; Weinstein, 1982), in combination with the variables gender and age, explained 21.9% of the variance on the VHI. Perceiving ones own voice as being distorted, dull, or hollow had a strong negative association with a general satisfaction about the sound quality of ones own voice. In addition, groupwise differences in own-voice descriptions suggest that a negative perception of ones voice could be influenced by alterations caused by hearing aid processing. Conclusions: The results indicate that hearing impairments and hearing aids affect several aspects of vocal satisfaction in older adults. A greater understanding of how hearing impairments and hearing aids relate to voice problems may contribute to better voice and hearing care.

Tidskriftsartikel (refereegranskat)abstract
- Normative language-based data are important for comparing speech performances of clinical groups. The Swedish Articulation and Nasality Test (SVANTE) was developed to enable a detailed speech assessment. This study's aim was to present normative data on articulation and nasality in Swedish speakers. Single word production, sentence repetition and connected speech were collected using SVANTE in 443 individuals. Mean (SD) and prevalences in the groups of 3-, 5-, 7-, 10-, 16- and 19-year-olds were calculated from phonetic transcriptions or ordinal rating. For the 3- and 5-year-olds, a consonant inventory was also determined. The mean percent of oral consonants correct ranged from 77% at age 3 to 99% at age 19. At age 5, a mean of 96% was already reached, and the consonant inventory was established except for /s/, /r/, /?/. The norms on the SVANTE, also including a short version, will be useful in the interpretation of speech outcomes.

Validity of auditory perceptual assessment of velopharyngeal function and dysfunction - the VPC-Sum and the VPC-Rate
- 2017
-

Tidskriftsartikel (refereegranskat)abstract
- Overall weighted or composite variables for perceptual auditory estimation of velopharyngeal closure or competence have been used in several studies for evaluation of velopharyngeal function during speech. The aim of the present study was to investigate the validity of a composite score (VPC-Sum) and of auditory perceptual ratings of velopharyngeal competence (VPC-Rate). Available VPC-Sum scores and judgments of associated variables (hypernasality, audible nasal air leakage, weak pressure consonants, and non-oral articulation) from 391 5-year olds with repaired cleft palate (the Scandcleft project) were used to investigate content validity, and 339 of these were compared with an overall judgment of velopharyngeal competence (VPC-Rate) on the same patients by the same listeners. Significant positive correlations were found between the VPC-Sum and each of the associated variables (Cronbachs alpha 0.55-0.87, P amp;lt; 0.001), and a moderately significant positive correlation between VPC-Sum and VPC-Rate (Rho 0.698, P amp;lt; 0.01). The latter classified cases well when VPC-Sum was dichotomized with 67% predicted velopharyngeal competence and 90% velopharyngeal incompetence. The validity of the VPC-Sum was good and the VPC-Rate a good predictor, suggesting possible use of both measures depending on the objective.

- Even though there are documented benefits of direct intensive intervention for children with speech sound disorders (SSDs), the intensity given at Swedish Speech Language Pathology services rarely exceeds once a week. Also, indirect therapy approaches are commonly employed. The purpose of the present case study was to investigate the effects of an intensive specialist therapy, based on non-linear phonological analysis and motor learning principles. The participant was a boy aged 4:10 years with severe SSD, who previously had received indirect therapy from age 3 with, very limited results. A single subject ABA design was used. At baseline, whole word match was 0%, Word shape CV match was 39% and PCC was 22, 7%. He had no multisyllabic words, no consonant clusters and no established coronals. Intervention was given 4 days weekly for 3 weeks in two periods with a 7-week intervening break and a post therapy assessments. Therapy was focused on establishing multisyllabic words, iambic stress pattern, clusters and coronals with the principle of using already established elements for targeting new elements. At post therapy assessment, whole word match was 39%, word shape CV match was 71% and PCC 69.1%. Multisyllabic words (86%), coronals (82%) and word initial clusters (80%) were established. Without being targeted, back vowels were also present and segment timing improved. The strong treatment effects of this study demonstrate that at least severe cases of SSD require the clinical knowledge and skills that only a SLP can provide and that frequent direct therapy is both beneficial and needed.

Manual till LINUS 2.0 : LINköpingsUnderSökningen 2.0: Ett fonologiskt bedömningsmaterial för barn från 3 år
- 2019
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- När ett barn med misstänkta tal- och språkavvikelser kommer till logoped för bedömning är det viktigt att samtliga aspekter av tal och språk beaktas. Under de år som svensk logopedi har vuxit fram, har ett flertal instrument för bedömning av barns tal- och språk tagits fram. Ett av dessa, Stora fonemtestet, som skapades i mitten av 1980-talet, har länge varit det enda vitt spridda testet av barns fonologi i landet. Testet fanns under flera år inte att beställa på förlag, vilket var ett av motiven till arbetet med att ta fram ett nytt fonologiskt bedömningsmaterial. Ett annat var att Enheten för logopedi vid Linköpings universitet sedan 2010 ingår i en större multicenterstudie med syftet att jämföra fonologiska avvikelser hos barn i olika länder. Inom ramen för detta projekt och genom några magisterarbeten i logopedi färdigställdes LINUS 2014. Som en direkt följd av det fortsatta internationella forskningssamarbetet och av feed-back från kollegor som använt materialet i sin kliniska vardag, kommer nu en ny version av materialet, LINUS 2.0. och finns för gratis nedladdning på http://phonodevelopment.sites.olt.ubc.ca/practice-units/swedish/. Vi hoppas att det även fortsatt skall komma till användning vid utredning av tal- och språkförmåga hos barn.Linköpings universitet, 2019Inger Lundeborg Hammarström

Tidskriftsartikel (refereegranskat)abstract
- 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.
