- Keith Thomas suffered a spinal cord injury in a 2020 diving accident, leaving him with virtually no ability to move or feel anything below his neck.
- In 2023, Thomas received a brain implant as part of an experimental study, with his family acquiring a dog around the same time.
- The device works by delivering tiny simultaneous electrical jolts to both Thomas' brain and spinal cord.
- With stimulation active, Thomas regained the ability to lift his arms and shoulders — movements he had lost since the accident.
- The implant also restored Thomas' sense of touch, allowing him to feel and stroke the fur of Bow, his malshipoo, again.
Why it matters: The study is among the first to restore both movement AND sensation in a quadriplegic patient using brain-spinal cord stimulation, addressing the sensory loss that other movement-focused implants leave unfixed. For Thomas personally, the milestone wasn't lifting his arm — it was feeling his dog's fur, showing that tactile restoration may matter more to patients than motor function alone.
