Selective Dorsal Rhizotomy

A neurosurgical procedure used to reduce spasticity in the legs and sometimes arms of people with cerebral palsy, by selectively cutting sensory nerve fibers in the spinal cord that contribute to abnormal muscle tone. SDR can improve mobility, reduce pain, and increase functional independence, though outcomes vary and the procedure carries risks including changes in sensation and the need for intensive post-operative rehabilitation. It is most commonly performed in childhood but can benefit adults as well.
