Feasibility of a brain-computer interface for people with tetraplegia

BrainGate2: Feasibility Study of an Intracortical Neural Interface System for Persons With Tetraplegia

NA · Massachusetts General Hospital · NCT00912041

This study is testing a new brain-computer interface that helps people with tetraplegia control a computer and other devices just by thinking, to see if it’s safe and effective.

What this trial studies

This study aims to evaluate the safety and feasibility of the BrainGate2 intracortical neural interface system, which allows individuals with tetraplegia to control a computer cursor and assistive devices using their thoughts. Participants will have sensors implanted in the motor-related cortex to facilitate this control. The research focuses on developing a medical device that can help restore abilities typically reliant on hand movement or speech for those with severe paralysis. The study will gather preliminary data on device performance and user experience.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with spinal cord injuries, brainstem strokes, or other motor neuron disorders resulting in complete or incomplete tetraplegia.

Not a fit: Patients with significant visual impairments or those on chronic immunosuppressive therapies may not benefit from this study.

Why it matters

Potential benefit: If successful, this could enable individuals with tetraplegia to regain control over their environment and improve their quality of life.

How similar studies have performed: Other studies have shown promise in using brain-computer interfaces for similar applications, indicating a potential for success in this approach.
