Filter by:The 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.
This 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.
Dysarthria is a speech disorder resulting in speech that is slow, slurred and difficult to understand, limiting a person's opportunities to study, work, and develop relationships. People with dysarthria often use communication aids to help them to communicate creating spoken messages using a keyboard, touchscreen or joystick. Communication aids can increase independence but are often too slow to keep pace with normal conversation. Developments in speech recognition technology have led to apps which can learn to recognise a set of words or sounds spoken by the individual with dysarthria, and connect these with a clear spoken output. The investigator's previous research provides some evidence that these voice input communication apps may be faster than traditional communication aids. This study aims to find out who can benefit from this technology, and what support they will need to use it successfully. This information can be used by professionals involved in providing communication aids, and will help the investigators to plan further research into their effectiveness. This research has two phases: 1. 20-30 individuals with dysarthria will be asked to use a voice input communication app for 6 months. The investigator's will collect information on whether VocaTempo improves their communication, and helps participants to reach their goals. 2. Focus groups will be held with professionals involved in providing and supporting people with communication aids, to understand factors affecting their ability to provide the support identified as needed in part 1 of the research. The investigators have a panel of communication aid users, who are advising and contributing throughout the study, for example, helping the investigators to identify informal support networks to recruit participants from. The investigators will let people know about the findings through support groups used by people with dysarthria, publications read by people involved in providing communication aids, and academic papers and conferences.
Difficulties with speech and language are the first and most notable symptoms of primary progressive aphasia (PPA). While there is evidence that demonstrates positive effects of speech-language treatment for individuals with PPA who only speak one language (monolinguals), there is a significant need for investigating the effects of treatment that is optimized for bilingual speakers with PPA. This stage 2 efficacy clinical trial seeks to establish the effects of culturally and linguistically tailored speech-language interventions administered to bilingual individuals with PPA. The overall aim of the intervention component of this study is to establish the relationships between the bilingual experience (e.g., how often each language is used, how "strong" each language is) and treatment response of bilinguals with PPA. Specifically, the investigators will evaluate the benefits of tailored speech-language intervention administered in both languages to bilingual individuals with PPA (60 individuals will be recruited). The investigators will conduct an assessment before treatment, after treatment and at two follow-ups (6 and 12-months post-treatment) in both languages. When possible, a structural scan of the brain (magnetic resonance image) will be collected before treatment in order to identify if brain regions implicated in bilingualism are associated with response to treatment. In addition to the intervention described herein, 30 bilingual individuals with PPA will be recruited to complete behavioral cognitive-linguistic testing and will not receive intervention. Results will provide important knowledge about the neural mechanisms of language re-learning and will address how specific characteristics of bilingualism influence cognitive reserve and linguistic resilience in PPA.
The purpose of this study is to obtain preliminary device safety information and demonstrate proof of principle (feasibility) of the ability of people with tetraplegia to control a computer cursor and other assistive devices with their thoughts.
Parkinson'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.
Nearly 90% of people with Parkinson's disease have speech and voice disorders that negatively impact their ability to communicate effectively in daily life. This study will test the hypothesis that a combined speech and exercise intervention will improve speech intelligibility in people with Parkinson's disease and speech impairment. This approach would offer an affordable way to continue to both instruct and encourage training by Veterans virtually indefinitely through the remote access technology. These findings may help VA clinicians provide optimal care for the many Veterans with Parkinson's disease and speech impairment.
The present study aims to investigate the short- and long-term effects of two weeks of intensive speech-language pathology intervention with additional physiotherapy, on aphasia and apraxia of speech (AOS) and their neural correlates in thirty persons with chronic stroke. Changes are studied following intensive treatment of aphasia and AOS with standardised speech-language testing and testing of communication and with voxel-based morphometry (VBM) analysis and resting state functional connectivity (rsFC).
Dysarthria is a common problem in Pakistan. therefore the current study aims to translate the dysarthria communication tools into urdu language for better understanding the population and the problem
Cerebral palsy (CP) is the most frequent cause of motor disability worldwide, with a prevalence of 2-2.5 per 1000 live births. Children with CP may experience a variety of difficulties with communication including speech. Communication impairment has been identified in at least 40% of children with CP, with 36-90% of CP children experiencing motor speech impairment. The aims of the current project are to test the effectiveness of intensive PROMPT treatment in a group of preschool children with CP and motor speech disorders (dysarthria/apraxia of speech) and to evaluate differences to the intervention response according to CP type, brain lesion severity and white matter integrity of corticospinal tract. We hypothesize that children with CP and motor speech disorders will benefit from 3 weeks of daily administration of PROMPT treatment and show measurable improvement of speech intelligibility on clinical and kinematic assessments, with 3 months stability. Outcome measures will include a standardized speech motor assessment as well as improvement in kinematic speech measures detected by a computerized system. We also hypothesize that children with dyskynetic CP will show more improvement induced by the PROMPT treatment as compared to children with spastic CP. We finally hypothesize that corticospinal microstructural integrity positively impact on intelligibility recovery, with children with better integrity having bigger improvements. Our study of PROMPT with children with varying types of CP meets current international priorities of testing and implementing effective, earlier interventions, therefore investing in the improvement infant's health based on evidence, as a future investment for individuals and the community.
