Contribuições da CIF para uma abordagem integral na atenção à Saúde de Crianças e Adolescentes / Contributions of ICF to an integral approach in the Health Care for Children and Adolescents

RESUMO Objetivo: Investigar a participação e funcionalidade de crianças e adolescentes com alterações de fala utilizando a Classificação Internacional de Funcionalidade, Incapacidade e Saúde. Método: Pesquisa descritiva-analítica de abordagem qualitativa-quantitativa com 30 participantes com alteração de fala (CAF) e 30 com desenvolvimento típico de fala (DTF). Para a coleta de dados, realizaram-se entrevistas semiestruturadas com os participantes, estudo de prontuário, observação dos participantes quanto aos aspectos de fala e aplicação de questionário estruturado com os responsáveis. Os dados coletados foram utilizados para seleção de qualificadores das categorias da Classificação Internacional de Funcionalidade, Incapacidade e Saúde. Para comparação dos qualificadores entre grupos, utilizou-se o Teste Mann-Whitney, e a análise de conteúdo temática, para as entrevistas. Resultados: Os participantes do grupo CAF relataram maior grau de dificuldade do que o grupo DTF. As alterações de fala repercutiram significativamente em Funções do Corpo (articulação e fluência), Atividades e Participação (conversa, relacionamentos, realização de rotinas e lidar com estresse) e Fatores Ambientais (atitudes de familiares, amigos e conhecidos). Conclusão: Os resultados evidenciam o impacto das alterações de fala e suas implicações sociais para estas crianças e adolescentes. A CIF permitiu compreender a saúde em complexidade e integralidade, possibilitando assim o planejamento de estratégias para amenizar o impacto dessas alterações individual e coletivamente. Podendo ser base, futuramente, para a criação de políticas públicas e ações que poderão melhorar a qualidade de vida e promover a saúde dessa população.

ABSTRACT Purpose: To investigate participation, and functionality of children and adolescents with speech disorders using the International Classification of Functioning, Disability and Health (ICF). Method: Descriptive and analytical research of qualitative and quantitative approach. The sample was composed of 30 participants with speech disorders and 30 with typical speech development. For data collection, it was conducted semi-structured interviews with the participants, medical record review, observation of speech aspects' participants, and analyzed study of medical records. The collected data were used to qualify the framework codes. The Mann-Whitney Test was used for comparison between groups, and thematic content analysis for the interviews. Results: Participants with speech disorders reported more difficulties than the participants with typical speech development. Speech disorders significantly impacted on the Body Functions (articulation and fluency), Activities and Participation (conversation, relationships, carrying out the routine and handling of stress) and Environmental Factors (attitudes of family, friends and acquaintances). Conclusion: The results show the impact of speech disorders and their social consequences for these children and adolescents. The ICF allowed us to comprehend health in all its complexity and integrality, making possible to plan strategies to soften the disorders impact in an individual and collective perspective. Then, ICF can be used, in the future, for elaboration of public policies and actions that will improve the quality of life and promote the health of this population.

ParkinSong: A Controlled Trial of Singing-Based Therapy for Parkinson's Disease.

Background. Communication impairment is one of the most common symptoms of Parkinson's disease (PD), significantly affecting quality of life. Singing shares many of the neural networks and structural mechanisms used during speech and, thus, has potential for therapeutic application to address speech disorders. Objective. To explore the effects of an interdisciplinary singing-based therapeutic intervention (ParkinSong) on voice and communication in people with PD. Methods. A controlled trial compared the effects of the ParkinSong intervention with an active control condition at 2 dosage levels (weekly vs monthly) over 3 months, on voice, speech, respiratory strength, and voice-related quality-of-life outcomes for 75 people living with PD. The interdisciplinary ParkinSong model comprised high-effort vocal and respiratory tasks, speech exercises, group singing, and social communication opportunities. Results. ParkinSong intervention participants demonstrated significant improvements in vocal intensity (P = .018), maximum expiratory pressure (P = .032), and voice-related quality of life (P = .043) in comparison to controls. Weekly ParkinSong participants increased vocal intensity more than monthly participants (P = .011). Vocal intensity declined in nontreatment control groups. No statistical differences between groups on maximum phonation length or maximum inspiratory pressure were observed at 3 months. Conclusions. ParkinSong is an engaging intervention with the potential to increase loudness and respiratory function in people with mild to moderately severe PD.

A scoping review of rehabilitation interventions for survivors of head and neck cancer.

Purpose: The objectives of this scoping review were to summarize, understand, and disseminate findings from a broad body of literature on rehabilitation interventions used with survivors of head and neck cancer. Method: Searches were conducted in six databases. Inclusion criteria were studies of adult head and neck cancer survivors with a predefined primary rehabilitation outcome as a result of an intervention. Excluded were studies not written in English, opinion papers, or studies where the intervention was not carried out by a rehabilitation healthcare service. A second level, full-text review of the studies was conducted. A thematic analysis was used to examine and combine study findings. Results: A total of 3804 results were retrieved from all sources resulting in 39 papers that were analyzed. The thematic analysis of the included papers represented interventions focusing on swallowing and nutrition, speech, physical therapy, assistive devices, complementary and alternative modalities, comprehensive interdisciplinary programs, and preventive rehabilitation programs. Conclusion: This review has provided an overview of the scope of rehabilitation interventions available for survivors of head and neck cancer and preliminary information about their efficacy. This is foundational information for the development and refinement of rehabilitation interventions and programs for head and neck cancer survivors. Implications for Rehabilitation The existing evidence suggests that survivors of head and neck cancer can benefit from early screening of potential rehabilitation needs and being involved in preventive rehabilitation programs pre-surgery when possible. Rehabilitation programs should consider swallowing interventions for patients as evidence reports improved swallowing function, decreased pain and discomfort, and reduced duration of feeding tube use. Rehabilitation programs should consider nutritional interventions after radiotherapy: Patients benefited from stabilized weights, improved nutritional status, and an improved quality of life. Physical exercise interventions demonstrated improvements in physical function, muscular endurance, range of motion, overall quality of life, and showed reductions in pain, and fatigue.

Video Game Rehabilitation of Velopharyngeal Dysfunction: A Case Series.

Purpose: Video games provide a promising platform for rehabilitation of speech disorders. Although video games have been used to train speech perception in foreign language learners and have been proposed for aural rehabilitation, their use in speech therapy has been limited thus far. We present feasibility results from at-home use in a case series of children with velopharyngeal dysfunction (VPD) using an interactive video game that provided real-time biofeedback to facilitate appropriate nasalization. Method: Five participants were recruited across a range of ages, VPD severities, and VPD etiologies. Participants completed multiple weeks of individual game play with a video game that provides feedback on nasalization measured via nasal accelerometry. Nasalization was assessed before and after training by using nasometry, aerodynamic measures, and expert perceptual judgments. Results: Four participants used the game at home or school, with the remaining participant unwilling to have the nasal accelerometer secured to his nasal skin, perhaps due to his young age. The remaining participants showed a tendency toward decreased nasalization after training, particularly for the words explicitly trained in the video game. Conclusion: Results suggest that video game-based systems may provide a useful rehabilitation platform for providing real-time feedback of speech nasalization in VPD.

[Home-based telerehabilitation after stroke]. / Telerehabilitation nach Schlaganfall im häuslichen Umfeld.

The use of modern information and telecommunication technologies enables telerehabilitation of neurological deficits in the domestic environment. The current state of studies on rehabilitative teletherapy for improvement of motor function and mobility deficits due to stroke is reviewed. Two neurolinguistic proof of concept studies investigating the efficacy of online interactive telespeech therapy are reported, which compared virtual screen to screen interactive telerehabilitation of aphasia after stroke and dysarthrophonia in Parkinson's disease to conventional face to face rehabilitation. The results of the studies indicate that the neurological rehabilitation of motor and communicative deficits in the domestic environment of patients by means of teletherapy is just as efficient as conventional rehabilitation. Under home-based telerehabilitation patient transfer becomes unnecessary. Rehabilitative Teletherapy is a posthospital component of a cross-sector supply chain for patients with handicaps or impairments due to stroke and other neurological diseases.

A qualitative case study in the social capital of co-professional collaborative co-practice for children with speech, language and communication needs.

BACKGROUND: Effective co-practice is essential to deliver services for children with speech, language and communication needs (SLCN). The necessary skills, knowledge and resources are distributed amongst professionals and agencies. Co-practice is complex and a number of barriers, such as 'border disputes' and poor awareness of respective priorities, have been identified. However social-relational aspects of co-practice have not been explored in sufficient depth to make recommendations for improvements in policy and practice. Here we apply social capital theory to data from practitioners: an analytical framework with the potential to move beyond descriptions of socio-cultural phenomena to inform change. AIMS: Co-practice in a local authority site was examined to understand: (1) the range of social capital relations extant in the site's co-practice; (2) how these relations affected the abilities of the network to collaborate; (3) whether previously identified barriers to co-practice remain; (4) the nature of any new complexities that may have emerged; and (5) how inter-professional social capital might be fostered. METHODS & PROCEDURES: A qualitative case study of SLCN provision within one local authority in England and its linked NHS partner was completed through face-to-face semi-structured interviews with professionals working with children with SLCN across the authority. Interviews, exploring barriers and facilitators to interagency working and social capital themes, were transcribed, subjected to thematic analysis using iterative methods and a thematic framework derived. OUTCOMES & RESULTS: We identified a number of characteristics important for the effective development of trust, reciprocity and negotiated co-practice at different levels of social capital networks: macro-service governance and policy; meso-school sites; and micro-intra-practitioner knowledge and skills. Barriers to co-practice differed from those found in earlier studies. Some negative aspects of complexity were evident, but only where networked professionalism and trust was absent between professions. Where practitioners embraced and services and systems enabled more fluid forms of collaboration, then trust and reciprocity developed. CONCLUSIONS & IMPLICATIONS: Highly collaborative forms of co-practice, inherently more complex at the service governance, macro-level, bring benefits. At the meso-level of the school and support team network there was greater capacity to individualize co-practice to the needs of the child. Capacity was increased at the micro-level of knowledge and skills to harness the overall resource distributed amongst members of the inter-professional team. The development of social capital, networks of trust across SLCN support teams, should be a priority at all levels-for practitioners, services, commissioners and schools.

The speech-language pathologist's role in multidisciplinary burn care: An international perspective.

PURPOSE: To explore international practices of speech-language pathology (SLP) within burn care in order to provide direction for education, training and clinical practice of the burns multidisciplinary team (MDT). METHOD(S): A 17-item online survey was designed by two SLPs experienced in burn care with a range of dichotomous, multiple choice and open-ended response questions investigating the availability and scope of practice for SLPs associated with burn units. The survey was distributed via professional burn association gatekeepers. All quantitative data gathered were analysed using descriptive statistics and qualitative data were analysed using content analysis. RESULT(S): A total of 240 health professionals, from 6 different continents (37 countries) participated within the study. All continents reported access to SLP services. Referral criteria for SLP were largely uniform across continents. The most dominant area of SLP practice was assessment and management of dysphagia, which was conducted in concert with other members of the MDT. CONCLUSION: SLP has an international presence within burn care that is currently still emerging.

Efecto de una estimulación musical en el desarrollo fonológico del lenguaje en niños del nivel preescolar / The effect of a musical stimulation in the phonological development of language in preschoolchildren

Introducción: en la edad preescolar, los niños frecuentemente intentan simplificar su lenguaje. Estas estrategias de simplificación, llamadas procesos de simplificación fonológica, los cuales se sub dividen en tres: de estructura silábica, de asimilación y de sustitución; estas son eliminadas paulatinamente durante el desarrollo fonológico hasta presentar nulos o escasos procesos a los seis años. Si los procesos persisten se considera un trastorno fonológico la cual es abarcada mediante la terapia fonológica tradicional la cual ofrece varias estrategias que buscan la generalización en las producciones del niño, es decir sin abordar todos los blancos posibles ya que los procesos presentan una importante variación individual. Una estrategia innovadora dentro de este enfoque es la aplicación de la música, la cual presenta varias similitudes con el lenguaje hablado. Objetivo: determinar el efecto de la estimulación musical con canciones infantiles en el desarrollo del aspecto fonológico del lenguaje de los alumnos de preescolar del Centro Educacional "Sagrados Corazones de Jesús y de María". Materiales y método: experimental intra-grupo, porque se realiza una intervención en una misma población que sirve de control. Se utiliza el TEPROSIF-R como instrumento de evaluación a 55 niños que acuden al preescolar y las canciones infantiles como instrumento de intervención. Resultados: se observó post intervención, una reducción significativa de la media de los procesos de estructura silábica y de los procesos de sustitución. Se apreció que la disminución de la media de los procesos de asimilación en relación a la media de los procesos de sustitución fue menos significativa, debido a que estos fueron menos frecuentes en los sujetos de estudio. Conclusión: tendencia a la reducción de los casos de niveles en riesgo y en déficit y por ende, un aumento significativo del número de alumnos con un nivel de desempeño fonológico normal en un 20%, debido al efecto directo de la intervención con canciones infantiles.

Introduction: in preschool, children often try to simplify their language. These strategies of simplification, called phonological simplification processes, which are sub divided into three: syllabic structure, assimilation and substitution are gradually eliminated during phonological development until they are reduced with little or no process at age of six. If processes persist they must be considered a phonological disorder which is approached by the traditional phonological therapy which offers several strategies that seeks generalization in productions of the child, without addressing all possible targets as processes exhibit significant individual variation. An innovative strategy in this approach is the application of music, which has several similarities with spoken language. Objective: to determine the effect of musical stimulation with nursery rhymes in the development of the phonological aspect of language in students who attend preschool education at the Educational Center "Sagrados Corazones de Jesus y María". Materials and methods: experimental intra-group because an intervention on the same control population is performed. The TEPROSIF-R is used as an assessment tool to evaluate the phonological aspect of language to 55 children attending the preschool education and nursery rhymes as an instrument of intervention. Results: a significant reduction of the average in the processes related to syllabic structure and substitution processes is observed. It is noted that the decrease in mean of assimilation processes in relation to the average substitution process was less significant, because these were less frequent in the study subjects. Conclusion: a tendency of reduced cases in levels at risk and deficit is evident and therefore, a significant increase in the number of students with a normal level of phonological performance by 20% due to the direct effect of the intervention with nursery rhymes.

[Clinical study of post-stroke speech apraxia treated with scalp electric acupuncture under anatomic orientation and rehabilitation training].

OBJECTIVE: To compare the differences in the clinical efficacy on post-stroke speech disorder between scalp electric acupuncture (EA) under anatomic orientation combined with rehabilitation training and simple rehabilitation training. METHODS: Sixty patients of post-stroke speech apraxia were randomized into an observation group and a control group, 30 cases in each one. In the observation group, under anatomic orientation, the scalp EA was adopted to the dominant hemisphere Broca area on the left cerebrum. Additionally, the speech rehabilitation training was combined. In the control group, the speech rehabilitation training was simply,used. The treatment lasted for 4 weeks totally. The speech movement program module in the psychological language assessment and treatment system of Chinese aphasia was used for the evident of efficacy assessment. The scores of counting, singing scale, repeating phonetic alphabet, repeating monosyllable and repeating disyllable were observed in the patients of the two groups. The assessment was done separately on the day of grouping and 4 weeks after treatment. RESULTS: In 4 weeks of treatment, the scores of counting, singing scale, repeating phonetic alphabet, repeating monosyllable and repeating disyllable were all improved as compared with those before treatment in the two groups (all P<0. 001). The results in the observation group were better than those in the control group (all P< 0. 05). The total effective rate was 100. 0% (30/30) in the observation group, superior apparently to 53. 3% (16/30) in the control group (P<0. 001). CONCLUSION: The scalp EA under anatomic orientation combined with' speech rehabilitation training obviously improves speech apraxia in stroke patients so that the speech disorder cani be relieved. The efficacy is better than that in simple rehabilitation training.

Paving the way for speech: voice-training-induced plasticity in chronic aphasia and apraxia of speech--three single cases.

Difficulties with temporal coordination or sequencing of speech movements are frequently reported in aphasia patients with concomitant apraxia of speech (AOS). Our major objective was to investigate the effects of specific rhythmic-melodic voice training on brain activation of those patients. Three patients with severe chronic nonfluent aphasia and AOS were included in this study. Before and after therapy, patients underwent the same fMRI procedure as 30 healthy control subjects in our prestudy, which investigated the neural substrates of sung vowel changes in untrained rhythm sequences. A main finding was that post-minus pretreatment imaging data yielded significant perilesional activations in all patients for example, in the left superior temporal gyrus, whereas the reverse subtraction revealed either no significant activation or right hemisphere activation. Likewise, pre- and posttreatment assessments of patients' vocal rhythm production, language, and speech motor performance yielded significant improvements for all patients. Our results suggest that changes in brain activation due to the applied training might indicate specific processes of reorganization, for example, improved temporal sequencing of sublexical speech components. In this context, a training that focuses on rhythmic singing with differently demanding complexity levels as concerns motor and cognitive capabilities seems to support paving the way for speech.

An independent SSVEP-based brain-computer interface in locked-in syndrome.

OBJECTIVE: Steady-state visually evoked potential (SSVEP)-based brain-computer interfaces (BCIs) allow healthy subjects to communicate. However, their dependence on gaze control prevents their use with severely disabled patients. Gaze-independent SSVEP-BCIs have been designed but have shown a drop in accuracy and have not been tested in brain-injured patients. In the present paper, we propose a novel independent SSVEP-BCI based on covert attention with an improved classification rate. We study the influence of feature extraction algorithms and the number of harmonics. Finally, we test online communication on healthy volunteers and patients with locked-in syndrome (LIS). APPROACH: Twenty-four healthy subjects and six LIS patients participated in this study. An independent covert two-class SSVEP paradigm was used with a newly developed portable light emitting diode-based 'interlaced squares' stimulation pattern. MAIN RESULTS: Mean offline and online accuracies on healthy subjects were respectively 85 ± 2% and 74 ± 13%, with eight out of twelve subjects succeeding to communicate efficiently with 80 ± 9% accuracy. Two out of six LIS patients reached an offline accuracy above the chance level, illustrating a response to a command. One out of four LIS patients could communicate online. SIGNIFICANCE: We have demonstrated the feasibility of online communication with a covert SSVEP paradigm that is truly independent of all neuromuscular functions. The potential clinical use of the presented BCI system as a diagnostic (i.e., detecting command-following) and communication tool for severely brain-injured patients will need to be further explored.

Training a new generation of speech-language pathologists with competences in the management of literacy disorders and learning disabilities in Hong Kong.

One of the recent developments in the education of speech-language pathology is to include literacy disorders and learning disabilities as key training components in the training curriculum. Disorders in reading and writing are interwoven with disorders in speaking and listening, which should be managed holistically, particularly in children and adolescents. With extensive training in clinical linguistics, language disorders, and other theoretical knowledge and clinical skills, speech-language pathologists (SLPs) are the best equipped and most competent professionals to screen, identify, diagnose, and manage individuals with literacy disorders. To tackle the challenges of and the huge demand for services in literacy as well as language and learning disorders, the Hong Kong Institute of Education has recently developed the Master of Science Programme in Educational Speech-Language Pathology and Learning Disabilities, which is one of the very first speech-language pathology training programmes in Asia to blend training components of learning disabilities, literacy disorders, and social-emotional-behavioural-developmental disabilities into a developmentally and medically oriented speech-language pathology training programme. This new training programme aims to prepare a new generation of SLPs to be able to offer comprehensive support to individuals with speech, language, literacy, learning, communication, and swallowing disorders of different developmental or neurogenic origins, particularly to infants and adolescents as well as to their family and educational team.

[Post-stroke speech disorder treated with acupuncture and psychological intervention combined with rehabilitation training: a randomized controlled trial].

OBJECTIVE: To assess the clinical efficacy on post-stroke speech disorder treated with acupuncture and psychological intervention combined with rehabilitation training. METHODS: The multi-central randomized controlled study was adopted. One hundred and twenty cases of brain stroke were divided into a speech rehabilitation group (control group), a speech rehabilitation plus acupuncture group (observation group 1) and a speech rehabilitation plus acupuncture combined with psychotherapy group (observation group 2), 40 cases in each one. The rehabilitation training was conducted by a professional speech trainer. In acupuncture treatment, speech function area in scalp acupuncture, Jinjin (EX-HN 12) and Yuye (EX-HN 13) in tongue acupuncture and Lianquan (CV 23) were the basic points. The supplementary points were selected according to syndrome differentiation. Bloodletting method was used in combination with acupuncture. Psychotherapy was applied by the physician in psychiatric department of the hospital. The corresponding programs were used in each group. Examination of Aphasia of Chinese of Beijing Hospital was adopted to observe the oral speech expression, listening comprehension and reading and writing ability. RESULTS: After 21-day treatment, the total effective rate was 92.5% (37/40) in observation group 1, 97.5% (39/40) in observation group 2 and 87.5% (35/40) in control group. The efficacies were similar in comparison among 3 groups. The remarkable effective rate was 15.0% (6/40) in observation group 1, 50.0% (20/40) in observation group 2 and 2.5% (1/40) in control group. The result in observation group 2 was superior to the other two groups (P<0.01, P<0.001). In comparison of the improvements of oral expression, listening comprehension, reading and writing ability, all of the 3 groups had achieved the improvements to different extents after treatment (P<0.01, P<0.001). The results in observation group 2 were better than those in observation group 1 and control group. CONCLUSION: Acupuncture and psychological intervention combined with rehabilitation training is obviously advantageous in the treatment of post-stroke speech disorder.

[Micro-current reflexotherapy in the rehabilitative treatment of the speech function disorders in children with cerebral palsy].

The objective of the present paper was to study the influence of microcurrent reflexotherapy on the compromised speech functions in children (n = 84) presenting with cerebral palsy in comparison with the control group comprised of children (n = 56) with the same problems treated by medicamental therapy. The microcurrent reflexotherapy was shown to be instrumental in the restoration of the compromised speech function. Moreover, it promoted positive dynamics of locomotor and cognitive disorders.

Science-based practice and the speech-language pathologist.

Evidence-based practice (EBP) is a well established concept in the field of speech-language pathology. However, evidence from research may not be the primary information that practitioners use to guide their treatment selection from the many potential options. There are various alternative therapy procedures that are strongly promoted, so clinicians must become skilled at identifying pseudoscience from science in order to determine if a treatment is legitimate or actually quackery. In order to advance the use of EBP, clinicians can gather practice-based evidence (PBE) by using the scientific method. By adhering to the principles of science, speech-language pathologists can incorporate science-based practice (SBP) into all aspects of their clinical work.

Clients becoming teachers: Speech-language pathology students' understanding of rehabilitation following clinical practicum in a rehabilitation setting.

There has been limited research investigating the conceptual development of rehabilitation in speech-language pathology (SLP) students. The aim of this study was to describe SLP students' understanding of rehabilitation following completion of a clinical practicum in a rehabilitation setting. This study was conducted using a qualitative approach according to grounded theory methodology. Semi-structured interviews were conducted with 10 SLP students who had completed a practicum in a rehabilitation setting. Interview data analysis revealed the emergence of five axial categories. Clients becoming teachers was identified as the core category, as the notion that clients were fundamental to students' understanding of rehabilitation occurred reliably throughout the data and related to all other categories. A theoretical model was proposed that demonstrated successive levels of support to students in the acquisition of their understanding of rehabilitation on practicum. Students' understanding of rehabilitation was derived from client-related interactions and factors experienced on practicum in rehabilitation settings. Rehabilitation practicum provided students with a rich and complex learning environment that may facilitate the development of the "core skills" identified for rehabilitation practice.

Rhythmic motor entrainment in children with speech and language impairments: tapping to the beat.

In prior work (Corriveau et al., 2007), we showed that children with speech and language impairments (SLI) were significantly less sensitive than controls to two auditory cues to rhythmic timing, amplitude envelope rise time and duration. Here we explore whether rhythmic problems extend to rhythmic motor entrainment. Tapping in synchrony with a beat has been described as the simplest rhythmic act that humans perform. We explored whether tapping to a beat would be impaired in children for whom auditory rhythmic timing is impaired. Children with SLI were indeed found to be impaired in a range of measures of paced rhythmic tapping, but were not equally impaired in tapping in an unpaced control condition requiring an internally-generated rhythm. The severity of impairment in paced tapping was linked to language and literacy outcomes.

The effect of nasal speaking valve on the speech under experimental velopharyngeal incompetence condition.

Velopharyngeal incompetence (VPI) is a contributing factor to speech disorders, frequently accompanying disorders, such as cleft palate, congenital paralysis of the soft palate, and cerebrovascular disease. For the treatment of these types of dysarthria, a Nasal Speaking Valve (NSV), which regulates nasal emission utilizing one-way valve, has been reported to be effective. As the unpleasantness while wearing the NSV was less than that with the conventional Palatal Lift Prosthesis, the NSV could be worn for a longer period of time. As NSV is inserted into the nostrils, this device could easily be provided for edentulous patients. This study aimed to evaluate the effect of NSV on experimentally induced VPI condition. Intelligibility of monosyllabic speech, intelligibility of conversational speech, nasalance score and acoustic analysis were used to evaluate the effect of NSV. Local infiltration anaesthesia was achieved to the area of levator veli palatini muscle and tensor veli palatine muscle of seven adult male subjects. In all subjects, remarkable suppression of the soft palate movement could be observed after the local infiltration anesthesia. Although the utterance supported by NSV under the experimentally induced VPI condition was less natural than the normal utterance, the intelligibility was markedly improved by the device. From the results of this study, the acoustic properties of NSV on the pure VPI condition, which was enabled by the newly established experimental induction, were revealed. This experimental model was also proved to provide a basis for the improvement in the treatment modalities for VPI.

[Conception and realisation of a prosody test battery]. / Konzeption und Realisierung einer Prosodie-Testbatterie.

BACKGROUND: Prosody reflects rhythmic and melodic aspects in speech and is one of the quality measures that shows--apart from pure speech understanding--a rising interest in the assessment of technical hearing aids, especially of cochlear implants. At present, there is no adequate test battery for the German speaking population. The test battery presented in this study aims to fill this gap. METHODS: The test battery consists of four different modules addressing different prosodic cues, namely duration, question vs statement, sentence stress, and speaker gender. One part of the test battery aims at reflecting everyday situations and was realized with six different speakers representing various pitch frequencies and speak rates. Another goal of the tests is to detect very small differences in prosody perception. Therefore, natural utterances were artificially modified by changing the underlying acoustic parameters (e.g. duration, fundamental frequency). Measurements were performed with 12 normal listeners in order to investigate the properties of the tests. RESULTS: As expected, the normal listeners revealed discrimination rates of close to 100% in that part of the test battery using natural utterances. For the part with the modified stimuli, all four modules revealed very steep discrimination functions indicating that the normal listeners were able to use very small changes in the acoustic parameters as cues for prosody perception. Moreover, the slope of the discrimination function revealed very low variability. CONCLUSIONS: Together with preliminary data from cochlear implant recipients who clearly showed different psychometric functions, the test battery seems suitable for a comprehensive evaluation of prosody perception. This facilitates future examinations of speech processing beyond the pure understanding of speech.
