New technologies are giving people with motor disabilities alternative communication and
control channels. The investigators are interested in using the Cyberlink Control System as
a hands free means to access a computer for people with Amyotrophic Lateral Sclerosis (ALS).
The goal of this project is to determine whether this device is a practical and realistic
means for ALS patients to communicate with only the use of facial muscle, brainwave, and eye
The benefit of this study may be of substantial value to many people with severe motor
impairment. Additionally, it is hoped that some of the study subjects may benefit by
incorporating hands-free computer use into their daily lives.
This study is intended to evaluate the effectiveness of the cyberlink as a tool for daily
communication compared to the standard manual letter board.
