Abstract: AIM: Although lateral bending reflex is important nerve behavior detection for children with cerebral palsy, the positive rate of it is concerned with the experience of the clinician; a new simple monitoring method is need. METHODS: 24 children with cerebral palsy and positive of lateral bending reflection were enrolled as positive group, 30 normal children with negative of lateral bending reflex were arranged as negative group (which were conformed by the deputy director of two or more physicians independent identification).The strength of lateral bending reflection in two groups was measured by a high density array type of surface EMG technique. RESULTS: The MMAV (quantitative strength indicators of lateral bending reflex) in the positive group (48.9±17.4) mV was significantly highly than that of in the negative group (3.1±1.2) mV (t=11.750, P<0.01). CONCLUSION: The condition of lateral bending reflection can be tested qualitatively and quantitatively by surface electromyography, it is worthy of clinical application.
