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 Overview

• Status: Completed
• Conditions: Amyotrophic Lateral Sclerosis
• Intervention / Treatment: Device: Brain Computer Interface for Wheelchair Tilt Control

Detailed Description

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.
