Spinal zaps tested to boost movement in Muscle-Weakening disease

This small pilot study explored whether a temporary spinal cord stimulator could improve leg strength and motor control in people with types 3 or 4 spinal muscular atrophy (SMA). Three participants had thin wires implanted near their lower spine for up to 29 days to deliver mild electrical stimulation. Researchers measured if turning the stimulation 'on' improved muscle strength, walking ability, and other motor functions compared to when it was 'off'.
