Paralyzed Man Regains Arm Movement and Touch After Double Neural Bypass

Keith Thomas, paralyzed from the chest down after a 2020 pool accident, regained arm and hand control plus tactile sensation through a double neural bypass that links his brain to arm nerves and uses finger sensors. After 35 weeks of training, arm strength improved 86% on the right and 62% on the left, enabling actions like scratching his nose and gripping objects, and letting him feel things like his dog’s fur. The findings, detailed in Nature, highlight the potential of brain–computer interface technology to restore movement and touch for people with paralysis.
