A STUDY OF EVOKED POTENTIAL AND GAIT ANALYSIS OF SPASTIC LIMBS SELECTIVE POSTERIOR RHIZOTOMY IN PATIENTS WITH CEREBRAL INJURY / 解放军医学杂志

ABSTRACT

Selective posterior rhizotomy was performed for the treatment of spastic limbs in patients with brain injury, and evoked potential and gait analysis were used to study its effect. The posterior roots of L 2～S 1 were separated from anterior roots and they were split into funiculi. Electric stimulation of the fumiculi was done.Those with low threshold were sectioned. Evoked potential and gait analysis were performed preoperatively and postoperatively. Selective posterior rhizotomy had been performed in 16 cases.They were followed up for 4 years. The result of the treatment was satisfactory.The rate of reduction in spasticity was 90 percent, and the rate of functional improvement was 80 percent.The study of evoked potential and gait analysis also showed that the effect of the operation was satisfactory.The results of selective posterior rhizotomy in the treatment of spastic limbs as a sequela of brain injury is promising,as judged by evoked potential and gait analysis.
