selective dorsal rhizotomy

Selective dorsal rhizotomy (SDR) is a surgical procedure used to reduce muscle stiffness and improve mobility in individuals with spasticity, often caused by cerebral palsy. During the operation, neurosurgeons identify and selectively cut abnormal nerve roots in the spinal cord that send excessive signals to muscles, causing tightness. This interrupts the overactive nerve signals, helping muscles relax and allowing for easier movement. SDR is typically performed on children or adults with significant spasticity who haven't responded well to other treatments, and it can lead to increased comfort and improved functional abilities.
