What is Selective Dorsal Rhizotomy (SDR)? 

SDR is the most effective treatment option for children and young adults with Spastic Cerebral Palsy. SDR has undergone more scientific scrutiny than any other procedure for treating Spastic CP. 

SDR permanently reduces or eliminates the spasticity in individuals with spastic CP by selectively cutting sensory nerves in the spine. An incision is made into the lower back. The L1 vertebrae is opened to access the spinal cord. The motor nerves are separated from the sensory nerves. Each of these sensory nerves are then separated into 4 or 5 rootlets. Each of these rootlets are then tested using electrical stimulation and the response of each of the muscles are measured. The nerve rootlets which produce the most abnormal responses are selectively cut. By cutting these nerves, the spasticity is permanently reduced or eliminated. As a result, the muscles can finally stop contracting abnormally all the time.
