Since 1992,task groups have used free nerve auto grafts to bridge partially transected nerves from the dominant area of the normal cerebral cortex to nerves that innervate spastic muscles from a diseased cerebral cortex,using transplanting sutures to alleviate the muscle spasm of cerebral palsy caused by different diseases. This has facilitated rebuilding of some of its neurological function. In this study,80 such patients were followed up,including 20 patients with traumatic brain injury,32 patients with stroke,and 28 pediatric patients with cerebral palsy. After postoperative follow-up of 3 to 21 years,the efficacy rate of this operation was 100% and the excellent and good spasm relief rate was 82.5%.
