Brain-controlled prosthetic communication for paralyzed individuals

Official title: Visuomotor Prosthetic for Paralysis

Run by California Institute of Technology · NCT01958086 · Data updated 2026-11-12

This study is testing a brain-chip that helps people with severe paralysis control a computer directly with their thoughts to see if it can improve their ability to communicate.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 22-65 with paralysis who can provide informed consent and have a stable psychosocial support system.

Probably not a fit

Patients with intellectual impairments, active infections, or severe psychiatric disorders may not benefit from this study.

What this trial studies

This clinical trial aims to explore the use of a brain-chip implanted in the brain to enable severely paralyzed individuals to control a computer interface directly with their brain activity. The study will utilize a prospective, longitudinal, single-arm early feasibility approach to assess the safety and effectiveness of a neural communication system. Participants will undergo initial training in simplified computer environments, with the ultimate goal of achieving autonomous control over a Google Android tablet. The research focuses on understanding how different brain areas encode movement intentions and how this knowledge can enhance prosthetic performance.

Why it matters

Potential benefit: If successful, this approach could significantly improve communication and independence for individuals with quadriplegia.

How similar studies have gone: Previous studies have shown promising results in using brain activity to control prosthetics, indicating potential success for this novel approach.
