Spinal zap trial offers hope for rare stiffness disease

This small pilot study tested whether spinal cord stimulation could reduce painful muscle rigidity and spasms in people with stiff person syndrome, a rare autoimmune condition. Two adults with the disease received temporary stimulation for up to 10 days, and researchers measured changes in pain, spasm frequency, sleep, and mood. The goal was to gather early safety and effectiveness data to guide future research.
