The system was tested with four patients with complete locked-in syndrome who couldn’t even move their eyes to communicate and had amyotrophic lateral sclerosis (ALS).
ALS is a neurodegenerative disease affecting nerve cells in the brain and spinal cord. Motor neurons get transported through the body to the spinal cord and to muscles. When the motor neurons begin to degenerate and die, the brain loses the ability to initiate and control muscle movement. Approximately 20,000 Americans have ALS, with 15 new cases occurring daily, according to the ALS Association.
