Feasibility of the BrainGate2 Neural Interface System in Persons With Tetraplegia (BG-Speech-02)...
AnarthriaDysarthria6 moreThe goal of this study is to improve our understanding of speech production, and to translate this into medical devices called intracortical brain-computer interfaces (iBCIs) that will enable people who have lost the ability to speak fluently to communicate via a computer just by trying to speak.
The Role of Cerebellum in Speech
Cerebellar AtaxiaDysarthria1 moreThis study will investigate the how the cerebellum is involved in speech motor learning over time and short-term corrections in patients with cerebellar ataxia and healthy controls. This will be accomplished through three approaches: behavioral studies, magnetic resonance imaging (MRI), and transcranial magnetic stimulation (TMS). During behavioral studies, participants will be asked to speak into a microphone while their voice is played back over earphones, and to do other speaking tasks. MRI will be acquired to perform a detailed analysis on brain function and anatomy related to speech and the cerebellum. In healthy controls, TMS will also be performed to temporarily disrupt the cerebellum before, during, or after the participant performs speaking tasks. Patients with cerebellar ataxia and healthy volunteers will be asked to complete behavioral studies and/or MRI; healthy volunteers may be asked to additionally participate in TMS.
The Efficacy and Feasibility of Smartphone-Based Speech Therapy for People With Post-Stroke Dysarthria...
Dysarthria as Late Effect of StrokeThis clinical trial aims to determine if a new smartphone-based speech therapy is effective and feasible for patients with post-stroke dysarthria. Participants in the intervention group will use the speech therapy app for 1 hour per day, 5 days per week, over a 4-week period. The control group will receive the same duration and frequency of traditional speech therapy as the intervention group. The study will help us understand if smartphone-based speech therapy is a viable treatment option for post-stroke dysarthria patients.
Application of Ideal Binary Masking to Disordered Speech
Hearing LossSensorineural1 moreDysarthria and hearing loss are communication disorders that can substantially reduce intelligibility of speech and the addition of background noise adds a further challenge. This proposal utilizes an established signal processing technique, currently exploited for improved understanding of speech in noise for listeners with hearing loss, to investigate its potential application to overcome speech-in-noise difficulties for listeners understanding dysarthric speech. Successful completion of this project will demonstrate proof-of-concept for the application of this signal processing technique to dysarthric speech in noise, and inform the development of an R01 proposal to perform a large-scale evaluation of the technology, and clinically meaningful implications, in a broad range of disordered speech types and severities.
Subthalamic Nucleus Deep Brain Stimulation in Speech Study
Parkinson DiseaseDysarthriaParkinson's disease (PD) patients treated with deep brain stimulation (DBS) of the subthalamic nucleus (STN) have unpredictable and varied speech outcomes after this treatment. Our research will prospectively document speech performance before, during and 6- and 12-months after STN-DBS in 80 surgically treated patients and compared with 40 non-surgical controls with Parkinson's disease. This study will provide unique insights into the role of STN in speech production, document speech outcome in a comprehensive fashion, identify factors that predict functional communication ability 12 months after STN-DBS, and test the feasibility of low frequency DBS in reversing DBS-induced speech declines in order to optimize treatment strategies for those living with Parkinson's disease.
The Effectiveness of Smartphone-Based Speech Therapy for People With Post-Stroke Dysarthria
Dysarthria as Late Effect of StrokeThis clinical trial aims to determine if a new smartphone-based speech therapy is effective self-treatment method for patients with post-stroke dysarthria. For this study, participants in the intervention group will use the speech therapy app for 1 hour per day, 5 days per week, over a 4-week period. The active control group will receive home-based speech therapy with the same duration and frequency as the intervention group. The study will help us understand if smartphone-based speech therapy is a viable treatment option for post-stroke dysarthria patients.
Rare Disease Patient Registry & Natural History Study - Coordination of Rare Diseases at Sanford...
Rare DisordersUndiagnosed Disorders316 moreCoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.
Rhythmic Entrainment in Bilingual Speakers With Dysarthria
Parkinson DiseaseAtaxiaThe objectives of this study are to determine i) the effect of rhythmic entrainment of speech with hand gestures and auditory rhythmic cues on intelligibility and speech naturalness in Spanish-accented speakers of English in two pathology groups: ataxic dysarthria and hypokinetic dysarthria secondary to idiopathic Parkinson's disease; and ii) the extent to which speech rate and effort are control parameters of entrainment. These objectives will be achieved with the following specific aims: Specific Aim 1: Determine the effect of three rates of hand gestures and auditory rhythmic cues and the degree to which learning and carry-over occur. Specific Aim 2: Determine the effect of increased speech effort, operationalized as clear speech, and the interaction effect of clear speech with hand gestures and auditory rhythmic cues. Specific Aim 3: Investigate the perception of speech rhythm and its relationship to entrainment.
Application of Vibration Wave Therapy to the Children Suffering From Cerebral Palsy and Tongue Spastic...
Cerebral PalsySpastic DysarthriaVibration therapy is the widely used in many neurological disorders for different type of problems. Recently, it is being used by researchers for the betterment of motor disorders and muscle movements of the cerebral palsy patients and significant results are obtained. Investigators are conducting this research to explore that whether this therapy can have some effect on the Spastic Tongue Dysarthria of the Cerebral Palsy patients.
