OBJECTIVE:
Selective dorsal rhizotomy via a single-level approach (SL-SDR) to treat spasticity 100% relies on the interpretation of results from the intra-operative neuroelectrophysiological monitoring. The current study is to investigate the role EMG interpretation plays during SL-SDR procedure with regard to the selection of nerve rootlets for partially sectioning in pediatric cases with spastic cerebral palsy (CP).

PURPOSE:
Our aim was to test whether the newly modified rhizotomy protocol which could be effectively used to guide single-level approach selective dorsal rhizotomy (SL-SDR) to treat spastic hemiplegic cases by mainly releasing those spastic muscles (target muscles) marked pre-operatively in their lower limbs was still applicable in spastic quadriplegic or diplegic cerebral palsy (CP) cases in pediatric population.

AIMS:
Spasticity remains a major impediment in the treatment of cerebral palsy (CP). The single-level selective dorsal rhizotomy (SDR) is a minimally invasive intervention that reduces spasticity in select patients. We provide a descriptive set of normative data that practitioners can utilize to help guide the single-level SDR procedure, including (1) physiological threshold values used to dissociate ventral from dorsal roots; (2) response characteristics of muscles; (3) descriptions of abnormal physiological responses; and (4) percentage of rootlets transected during surgery.

PURPOSE:
It still remains challenging to treat CP cases with spastic hemiplegia using SDR via a single-level approach when guided by the traditional EMG response grading system. Our aim was to assess the feasibility and effectiveness of a newly modified protocol-guided single-level laminectomy SDR to treat such pediatric patients.
