Non-invasive Brain Stimulation as a Treatment for Dysarthria Post-stroke
DysarthriaStrokeThe proposed study aimed to determine if tDCS can help post-stroke patients with dysarthria.
Improve Speech Using an In-the-ear Device in Parkinson's Disease
Parkinson's DiseaseDysarthriaThis project will systematically examine the therapeutic effect of altered auditory feedback provided by the in-the-ear device on the speech impairments in patients with Parkinson's disease. Many patients with PD have difficulty starting their speech even though they know the words they want to say. They experience 'freezing' of the jaw, tongue and lips. When they eventually get their speech started, they have a hard time moving it forward. They keep on saying the same words or phrases over and over again while their voice gets softer and softer. Many words also run together. These symptoms make patients' speech very hard to understand and directly affect their care and quality of life. Currently, there is no effective medical or surgical treatment for these speech symptoms. We have tested an in-the-ear therapeutic device that provides altered auditory feedback in eight patients with PD and moderate to severe speech impairment and the results are encouraging. We will recruit 100 patients with PD and moderate to severe speech impairment for Phase A and 20 for Phase B of the study. They will use the device routinely to provide the altered auditory feedback as they speak to improve their speech intelligibility.
Effect of Noninvasive Brain Stimulation on Hypokinetic Dysarthria in Parkinson's Disease
Parkinson DiseaseHypokinetic dysarthria (HD) is common in Parkinson's disease (PD) patients and responds only partially to pharmacotherapy and surgery. The investigators will explore long-term effects of repetitive transcranial magnetic stimulation (rTMS) applied over right superior temporal gyrus, brain area known to be engaged in the feedback control of voiced speech. The project results will allow for the identification of potential therapeutic effects of rTMS as a tool that could contribute to the speech therapy of HD in PD patients. The results will also enhance our understanding of brain mechanisms underlying specific long-term effects of rTMS.
Perceptual Training to Improve Listeners' Ability to Understand Speech Produced by Individuals With...
DysarthriaIntelligibility1 moreThere exist very few effective treatments that ease the intelligibility burden of dysarthria. Perceptual training offers a promising avenue for improving intelligibility of dysarthric speech by offsetting the communicative burden from the speaker with dysarthria on to their primary communication partners-family, friends, and caregivers. This project, utilizing advanced explanatory models, will permit identification of speaker and listener parameters, and their interactions, that allow perceptual training paradigms to be optimized for intelligibility outcomes in dysarthria rehabilitation. This work addresses this critical gap in clinical practice and sets the stage for extension of dysarthria management to listener-targeted remediation-advancing clinical practice and enhanced communication and quality of life outcomes for this population.
Intensive Dysarthria Sessions in Adults and Children With Down Syndrome
DysarthriaDown SyndromeThis research study is designed to investigate the feasibility and treatment effects of a behavioral speech treatment in adults and children with Down Syndrome (DS) and dysarthria. The speech sessions will provide an intensive, articulation-based intervention focused on increasing effort during speech production via use of "clear speech." A single subject multiple baselines across subjects design will be employed in a total of six subjects divided into two groups of three. Changes in dependent measures will be determined by visual inspection, effect size determination, and time series analysis. The study follows accepted procedures in rehabilitation treatment and research and there are minimal foreseeable risks associated with participation.
Efficacy of Voice Treatment for Parkinson's Disease
Parkinson's DiseaseDysphagia1 moreThe purpose of the research study is to determine the effects of two different kinds of speech treatment on certain behaviors in individuals with parkinson's disease. These behaviors include speech, voice, related communication behaviors, swallowing and body movement.
Evaluating the Efficacy of Opti-Speech for Speech Treatment
Articulation DisorderDysarthria1 moreThe purpose of this study is to determine if feedback from a three-dimensional real-time visualization of the tongue, a program called Opti-Speech, can be used to improve speech.
A Multidimensional Study on Articulation Deficits in Parkinsons Disease
Parkinson DiseaseDysarthria1 moreArticulatory deficits are present in most speakers with dysarthria, which negatively impacts their speech intelligibility, yet little is known about the relationship between articulatory movement and speech intelligibility. This study will examine the relationship between articulation measures, both acoustic and kinematic, and their relationship to perceptual measures (i.e., speech intelligibility and articulation ratings) in 30 individuals with dysarthria secondary to Parkinson's disease and 30 neurologically healthy adults of the same age. The findings will have implications for behavioral management.
Laryngeal Adaptation for Speech and Swallowing
StrokeSpinocerebellar Ataxia3 moreThis study will test laryngeal adaptation in speech and swallowing function in healthy adults, in patients with cerebral stroke, and in patients with spinocerebellar ataxia type 6. The findings from this proposal will be the first step toward implementing rehabilitation techniques that help patients to prevent speech and swallowing errors before they occur.
A Systematic Investigation of Phonetic Complexity Effects on Articulatory Motor Performance in Progressive...
Amyotrophic Lateral SclerosisParkinson DiseaseThe goal is to improve the fundamental knowledge about articulatory motor performance in people with Lou Gehrig's disease (also known as ALS) and Parkinson's disease (PD), in order to develop more sensitive assessments for progressive speech loss, which may lead to the improved timing of speech therapies.
