H-Reflex recovery curve in syringomyelia

H-reflex recovery curves were obtained from 13 patients with cervical syringomyelia to assess motor neurone excitability, and results were compared with control subjects and patients with spasticity due to stroke. The median nerve was stimulated at the elbow and the H-reflex was recorded from the fl...
