Filter by:In a retrospective analysis of already existing clinical assessment data from patients with functional voice disorders the following aspects will be sampled, encoded and analysed: Outcomes pre and post treatment of 1. subjective voice symptoms measured by Voice Handicap Index (VHI-9i), 2. perceptual voice symptoms according to Grading-Roughness-Breathiness-Asthenia-Strain Scale (GRBAS Scale), 3. instrumental acoustic analysis parameters Jitter (%), speaking voice profile: mean and range of speaking pitch and intensity, max. intensity and mean pitch of calling voice, singing voice: min./max. and range of pitch and intensity, maximum phonation time, Dysphonia Severity Index (DSI).
Voice therapy is the standard-of-care for many of the nearly 140 million people in the United States who suffer from voice disorders,1 yet patients claim that current therapies are ineffective at meeting their voice needs.2 Published data by our research team indicate that patients think that transfer of target voice techniques to every day voice use (i.e. conversation) is the most difficult aspect of therapy,2 and that training techniques in conversation is the most useful aspect of voice therapy.2 Unfortunately, traditional voice therapy programs spend little, if any, time training voice techniques in conversation.3 This lack of functional specificity in voice therapy may contribute to the estimated 65% attrition rate.4 Even after some form of treatment, patients are still struggling with daily conversational voice use, and voice disorders continue to cause serious disability, stress and depression, which negatively affects social functioning and job performance.5 A new voice therapy program, Conversation Training Therapy (CTT), based on published patient reports on dissatisfaction with traditional therapy, was developed by the Investigators. It was honed with recommendations from expert clinical voice-specialized speech-language pathologists, and successfully piloted in a small case series of patients with voice problems. The investigators objective in this application is to test CTT in the rehabilitation of patients with voice disorders. The investigators hypothesize that, as demonstrated in the investigators preliminary case studies, these methods will result in early treatment success, and reduce the time required to reach therapeutic goals, thereby reducing costs associated with voice treatment.
The purpose of this study is to verify the effects of two speech-pathology interventions: vocal warm-up and respiratory training in teachers who work in a public school of the city of Salvador-Bahia, with or without complaints of vocal disorders. It is a preventive study and the hypothesis is that both approaches can produce positive voice changes, but the Vocal Warm-up will produce the most significant changes.
The purpose of the study "A comparison of vocal demands with vocal performance among classroom teachers" is to gather information about the voice production of teachers using three separate strategies: (a) measures of voice assessed with the Computerized Speech Lab (CSL) and the Phonatory Aerodynamic System (PAS) instruments in the SIUC Voice Lab.
The purpose of the study, Effects of Interaction of Caffeine and Hydration on Voice Performance, is to gather information about the effects of caffeine and hydration upon voice performance. The research question involves whether systemic hydration may reduce degradation on voice performance caused by caffeine ingestion. It is hypothesized that the hydration conditions will result in a less degraded vocal performance as compared with the nonhydration condition.The investigation involves abstention from any caffeine ingestion for 24 hours - from 8pm the day before testing to 8am the morning of testing. In addition, preparation for participation involves abstaining from ingesting any foods and liquids for 12 hours - from 8pm to 8am of the following morning. Each test will take about 10 minutes.
The proposed series addresses the prevention and treatment of voice problems in teachers. Data in the literature clearly identify voice disorders as teachers' primary occupational risk not only in the U.S. but also internationally. Moreover, voice problems constitute a global women's health concern. Until recently, few reports have been available around the treatment of these problems in teachers, and even fewer have addressed the equally important question of prevention. The present studies are conducted within the context of a long-range goal to identify effective intervention methodologies for both the prevention and treatment of voice problems in teachers taking into consideration multicultural and linguistic factors. The present studies will report pragmatic data around the effectiveness of two theoretically-driven approaches to the prevention and treatment of voice problems in teachers, (a) voice hygiene education (VH) and (b) voice hygiene education + voice production training in "resonant voice" (VH+VP, essentially the Lessac-Madsen Resonant Voice Therapy program). Participants will be student teachers in Pittsburgh and Hong Kong, who will be followed from student teaching across their second full year of employment as a professional teacher. The central aims are: [1] to evaluate the effectiveness of VH and VH+VP for the prevention of future voice problems in student teachers who are vocally healthy at the outset of the protocol, versus the treatment of voice problems in student teachers who already have them at some level; [2] to evaluate the generality of the findings across teachers in the U.S. and China, using appropriate linguistic and cultural adaptations of the interventions; and [3] to evaluate the feasibility of an internet-based voice exercise and reporting program as a supplement to face-to-face interventions. Ergonomic and personal factors will also be evaluated for their differential ability to predict the risk for future voice problems in teachers. The results should be useful at a practical level, and should also lay the groundwork for future studies assessing similar issues around the prevention of voice problems in teachers, in particular as influenced by multicultural factors within the U.S. The results should also be useful for future studies investigating causal pathways in interventions around these problems.
The study compares two different approaches of voice therapy. Vocal Functional Exercises (Stemple,1997) and Voice Amplification using a portable amplifier (Tsi Supervoz II - Tecnisystem do Brasil TSI 1210).
Dysphagia in Parkinson's disease(PD) is common and its presence is related to motor and sensory abnormalities, and incoordination between swallowing and breathing. Despite harming as respiratory infections and increased risk of death, treatment of this condition remains uncertain. This study aims to evaluate the effect of oral motor exercises on the swallowing dynamics and quality of life of dysphagic Parkinson's disease patients. This study is an open trial, self-paired and blinded to the examiner. The participants will perform oropharyngeal exercises for five weeks and will be evaluated before and after intervention by swallowing videofluoroscopy and questionnaires about quality of life in dysphagia (SWAL-QOL).
The objective of this clinical and experimental study was to verify the immediate effect of vocal techniques: vibration, nasal sound and articulation in women without vocal complaints.
The diagnosis and management of childhood dysphonia is a significant clinical problem; however, there have been few studies aimed at defining standard assessment methods for pediatric dysphonia. Accordingly, pediatric dysphonia is difficult to diagnose and it is difficult to quantify change following treatment. The long-term goal of this research program is to develop valid, responsive, reliable, and age-appropriate methods for assessing vocal pathology in children. In the present small grant, our objective is to define assessment methods that are appropriate for use in determining response to treatment. Our main focus, therefore, is the issue of assessment responsivity. The first specific aim is to develop a set of responsive measures of vocal pathology in school-aged children by inducing short-term change in vocal status via behavioral and medical management of extraesophageal reflux disease (EERD). Because we are treating children suspected of EERD, this study also presents the opportunity for examining the benefits of combined vocal hygiene and medical management in the treatment of pediatric EERD. Accordingly, our second specific aim is to determine predictive criteria for improvement in vocal status in dysphonic children suspected of EERD. Our hypothesis is that a particular set of measurements will emerge as particularly responsive to change in vocal pathology in this population, and will allow for informed prediction of degree of improvement with treatment. The proposed research is significant in filling a gap in knowledge in childhood dysphonia assessment and treatment, which are important clinical issues consistent with the mission and intent of the NIDCD. Because phonatory disorders in children may have lasting negative effects, studies geared toward accurate assessment and treatment are very important.
