RESUMEN
The ability to perform a 'selective' dorsal rhizotomy has been challenged. EMG responses are inconsistent and often do not represent reflex responses. We perform nonselective partial dorsal rhizotomy (NSPDR) when reflex response is not evident. Ten children undergoing primarily NSPDR were evaluated preoperatively and postoperatively with the Modified Ashworth Scale, gait lab analyses gross motor function measure and the NSPDR was performed by nonselectively sectioning 50-75% of the dorsal roots not demonstrating a reflex response. Standard selective rhizotomy was performed in the remainder. Only 17 of 106 (16%) dorsal roots demonstrated reflex responses. The results reported in this study demonstrate a benefit to patients undergoing primarily NSPDR which is similar to that reported for patients in whom a selective procedure was intended.
