An In-home Study of Brain Computer Interfaces
The investigators are developing a tool to help people who are severely paralyzed. This tool is called a brain-computer interface (BCI). BCIs can connect to computers or other electronic devices.
This study allows a person with ALS to communicate, control their wheelchair tilt and perform other tasks using a BCI, thus increasing their independence.

|Study Design:||Intervention Model: Single Group Assignment
Masking: No masking
Primary Purpose: Supportive Care
|Official Title:||An In-home Study of Brain Computer Interfaces|
- Duration of BCI Usage by Persons With ALS. [ Time Frame: Monthly measurements for a period of up to 18 months. ]Number of months of BCI usage by each participant.
- Changes in Accuracy of BCI for Controlling Devices and Text [ Time Frame: 6 months, 12 months, 18 months ]Changes in Accuracy Percentage (i.e., cumulative correct selections per month divided by the cumulative number of intended sections per month). Looking for trends over each 6 month period.

|Brain Computer Interface In-Home Use||
Device: Brain Computer Interface for Wheelchair Tilt Control
Patients will be given the BCI for use in-home, as long as they use the BCI at least 10 hours per week and complete monthly performance assessment sessions.
This small-scale study of the feasibility of a BCI to operate the tilt position of a power wheelchair was also designed to determine the conditions and support structures necessary for use of a BCI in the home. In this study, people with Amyotrophic Lateral Sclerosis (ALS) will have a BCI in their home. They will receive training in order to operate and maintain the BCI. The BCI will allow them to access at least one task of primary interest to them. Task may include communication, computer access, control of assistive technology, or control of wheelchair seat position. Data concerning the use of the BCI will be collected throughout the study. Custom installations will be made for each participant to connect to their wheelchair and provide communication options if needed. Each installation is expected to be a unique prototype because of the differing control requirements for the individual wheelchairs in use by the participants.
We intended to enroll six participants, but were only able to enroll one.
