Study Description
Brief Summary:

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.


Condition or disease Intervention/treatment
Amyotrophic Lateral Sclerosis 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.


Study Design

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 1 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Supportive Care
Official Title: An In-home Study of Brain Computer Interfaces
Study Start Date : January 2010
Primary Completion Date : May 2011
Study Completion Date : May 2011


Arms and Interventions

Arm Intervention/treatment
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.


Outcome Measures

Primary Outcome Measures :
  1. 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.


Secondary Outcome Measures :
  1. 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.
