Using a brain-computer interface to help people with speech difficulties communicate

Understanding and Restoring Speech Production Using an Intracortical Brain-computer Interface

NA · Massachusetts General Hospital · NCT06094205

This study is testing a brain-computer interface to help people who can't speak due to conditions like ALS communicate by turning their thoughts into speech.

What this trial studies

This study aims to enhance communication for individuals who have lost the ability to speak due to neurological conditions such as ALS or spinal cord injuries. It utilizes an implanted brain-computer interface (iBCI) that captures brain activity when participants attempt to speak, translating their intentions into computer-generated speech. By analyzing how brain cells work together to produce speech, the study seeks to improve the technology and understanding of speech production in affected individuals.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 80 with complete or incomplete tetraplegia or other motor neuron disorders.

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

Why it matters

Potential benefit: If successful, this approach could significantly improve communication abilities for patients with severe speech impairments.

How similar studies have performed: Other studies involving brain-computer interfaces have shown promise in restoring communication abilities, indicating potential success for this approach.
