Amyotrophic Lateral Sclerosis, Brain Stem Infarctions, Locked in Syndrome, Muscular Dystrophy, Spinal Cord Injuries, Tetraplegia

Keywords

Brain computer interface, Assistive device, Environmental control, Communication device, quadriplegia, tetraplegia

Brief summary

The purpose of this study is to obtain preliminary device safety information and demonstrate proof of principle (feasibility) of the ability of people with tetraplegia to control a computer cursor and other assistive devices with their thoughts.

Detailed description

The goal of the BrainGate2 research and development project is to identify the core methods and features for a medical device that could allow people with paralysis, including severe speech impairment, to recover a host of abilities that normally rely on the hands or on speech.

Interventions

DEVICEPlacement of the BrainGate2 sensor(s) into the motor-related cortex

Up to six 4x4 mm BrainGate2 sensor(s) are placed into the motor-related cortex (including speech-related areas of cortex), connected to one, two, or three percutaneous pedestals. Neural recordings are made at least weekly for a year or more.
