Upper-extremity spasticity and functionality after selective dorsal rhizotomy for cerebral palsy: a systematic review

Lumbosacral selective dorsal rhizotomy is a neurosurgical treatment option to reduce spasticity in the lower extremities in children with cerebral palsy. Surprisingly, concomitant improvement of spasticity in the upper extremities and functionality of the hands has been sporadically reported postoperatively. In this systematic review, the authors aimed to quantify the postoperative improvement in upper-extremity spasticity and functionality, identify predictors, and discuss underlying mechanisms.
