[The effect of selective dorsal rhizotomy on motor function in patients with infantile cerebral palsy].

The authors analyze the outcomes of surgical treatment in 15 CP patients with lower paraparesis who had been treated with selective dorsal rhizotomy at the L2-S2 level. All the patients were examined by neurological study, EMG, EEG, visual evoked potential (VEP) recording and motor reaction time estimation. Based on the findings, it is suggested that SPR lumbosacral spinal level may affect cerebral function. Some motor functional changes are associated with this impact. Possible mechanisms of these changes are discussed.
