Clinical Trial 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.

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.
