Improvement in Upper Extremity Function and Trunk Control After Selective Posterior Rhizotomy

Abstract

Abstract Selective posterior rhizotomy is being increasingly used in the treatment of spasticity associated with cerebral palsy. Anecdotal reports in the literature note that this procedure results in improved upper extremity function and trunk control. We present a systematic analysis of the results of selective posterior rhizotomy performed on patients with cerebral palsy at Santa Rosa Children’s Hospital. Patients were videotaped before surgery and one year postoperatively. These videos were reviewed blind by an occupational therapist who graded patients’ performance on three tasks: assumption of side sitting, maintenance of side sitting, and block building. Statistically significant improvements were noted in all three categories with p values of .0003, .0001, and .0044 respectively. These results support the anecdotal reports of improvement in upper extremity function and trunk control with selective posterior rhizotomy.
