VA tests common drugs to reconnect brain and spinal cord after injury

This study tested three already-approved medications to see if they could temporarily improve hand function when combined with hand training exercises in people with chronic spinal cord injuries. Researchers measured how well 25 participants could perform hand tasks and how their nerves responded after taking single doses of different drugs. The goal was to understand how these medications might help strengthen communication between the brain and spinal cord, though no long-term benefits were expected from this early research.
