NCT ID: NCT04897711 Completed - Dysarthria Clinical Trials

Perceptual Training to Improve Listeners' Ability to Understand Speech Produced by Individuals With Dysarthria

Start date: April 26, 2021
Phase: N/A
Study type: Interventional

There 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.

NCT ID: NCT04126226 Completed - Oral Cancer Clinical Trials

Quality of Life in Patients Treated for Tongue and/or Jaw Neoplasia Before and After Speech Therapy

Start date: March 1, 2018
Phase: N/A
Study type: Interventional

This study aims to verify the impact of four speech therapy sessions on the Quality of Life of patients treated for malignant tongue and/or jaw cancer, using as measure specific questionnaires of speech and swallowing. The hypothesis is that after treatment with exercises and speech therapy guidance, patients will present better indicators on Quality of Life related to speech and swallowing.

NCT ID: NCT03698539 Completed - Down Syndrome Clinical Trials

How Stuttering and Gestures Influence the Intelligibility of Individuals With Down Syndrome

Start date: December 5, 2018
Phase:
Study type: Observational

This study wants to determine the relationship between spontaneous hand gestures, stuttering and intelligibility in individuals with Down syndrome. One third of these individuals has fluency problems, such as stuttering. Gesture use appears to be a strength in individuals with Down syndrome. While they are able to compensate for their language problems, it is not clear if they also use gestures to compensate for their speech problems. Therefore, this study will observe the impact of their gesture use on the stuttering frequency/severity and on the intelligibility of children with Down syndrome. This study has three research questions. The first question is: Is there a difference in gesture use between individuals with Down syndrome who stutter and individuals with Down syndrome who do not stutter? The hypothesis is that the children who stutter will make more gestures to compensate for the fluency problems. The kind of spontaneous hand gestures will also be considered. These results will be compared to those of typical developing individuals. The second research question is: Are stuttering events that are accompanied by a gesture more intelligible than stuttering moments that are not accompanied by a gesture? Research showed that the use of signs has an positive impact on the speech intelligibility of individuals with Down syndrome. Here it is investigated if this is also true for spontaneous hand gestures. In case of better speech intelligibility it is investigated if the gain in intelligibility is caused by how recognizable the gesture is or by the effect of the gestures on speech itself. The effect of different types on the speech intelligibility of the stuttering events will also be investigated. Typically developing individuals who stutter will function as control group. The third research question is: 'Does gestural priming have an influence on the fluency of children with Down syndrome? Gestural priming is a secondary speech signal that gives feedback to the first speech signal by simultaneously mimicking the first speech signal. In this research a hand puppet will imitate the mouth movements of the participants. Next to that, the speech will be simultaneously be accompanied by beat gestures, meaningless up and downward movements. The hypothesis is that due to mirror neurons, the participants will become more fluent. Mirror neurons are neurons in the brain that can produce a neural basis for fluency by the perception of the second speech signal.
