Amyotrophic Lateral Sclerosis, Brain Stem Stroke, Cerebral Palsy, Speech Disorders, Traumatic Brain Injury
Conditions
Brief summary
The goal of this project is to test a new AAC-BCI device comparing gel and dry electrode headgear used for communication while providing clinical care. Innovative resources will be employed to support the standard of care without considering limitations based on service billing codes. Clinical services will include AAC assessment, AAC-BCI device and treatment to individuals with minimal movement due to amyotrophic lateral sclerosis (ALS), brain stem strokes, severe cerebral palsy, traumatic brain injury (TBI) and their family support person. This is a descriptive study designed to measure and monitor the communication performance of individuals using the AAC-BCI, any other AAC strategies, their user satisfaction and perceptions of communication effectiveness, and the satisfaction of the family support persons.
Detailed description
This clinical trial follows a descriptive study design collecting data to measure and monitor variables related to the standard of care in providing speech language pathology augmentative and alternative communication clinical (AAC) assessment and treatment. The study tracks participants through the AAC, speech generating device trial and AAC-BCI trial processes. In addition this study measures and monitors the communication performance of individuals using the AAC-BCI and any other AAC strategies for treatment in the home. Data on communication performance, user satisfaction, and perceptions of communication effectiveness are gathered over monthly visits along with the satisfaction and perceptions of communication effectiveness by the family support persons.
Interventions
BEHAVIORALSpeech generating device (SGD) evaluation including BCI access
At the initial evaluation the participants will review the full range of AAC options and speech generating devices (SGDs) and complete a speech and language evaluation. The second evaluation date will involve a trial of SGDs matched to the participant's assessment results. The third visit is the trial of an AAC system with BCI access. Should the dry electrode headgear for BCI access prove ineffective, then the gel electrode cap will be offered to the participant for trial. At the end of the third visit, the evaluation results will be discussed with participant and family, and they will be asked to select the preferred SGD.
BEHAVIORALTraining and treatment
Participants receive training on the selected SGD followed by monthly treatment sessions from the SLP who monitors performance. In some cases the participants' SGD will be an AAC system with BCI access. In this case training will also include an identified system support person. Use of the SGD is monitored on a monthly basis through home visits and/or tele-practice sessions, when requested. Technical support for the SGD is provided on an as needed basis or when requested by the participant or support person.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in daily communication performance | Baseline vs. 1 month | Monitoring daily use of a speech generating device (SGD) for communication. Average communication rate based on total number of words used during the day. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| User satisfaction of speech generating device (SGD) for daily communication | Baseline vs. 1 month | Rating scale of user satisfaction with a range of 0-21 with a lower score representing a better outcome. |
| User satisfaction of speech generating device (SGD) or daily communication | 15 months vs. 16 months | Rating scale of user satisfaction with a range of 0-21 with a lower score representing a better outcome. |
