Study on clinical effectiveness of lower limb spasticity of non-cerebral palsy treated by selective posterior rhizotomy

Objective To study curative effect of selective posterior rhizotomy(SPR) in treatment of lower limb spasticity in patients with non-cerebral palsy.Methods Thirty six cases of non-cerebral lower limb spasticity(8 cases of cerebrovascular accident;4 cases of hydrocephalus;19 cases of cerebral or spinal trauma and 5 cases with other causes) were treated with selective posterior rhizotomy(SPR) during October 2008 to June 2011.Muscle tonicity and gait analysis were measured before and after operation.Results All cases were followed up for 3~18(with mean of 5.3±1.8) months.Gait analysis and walking ability were significantly improved after treatment.Reduction of spasticity was obtained in every case,and their muscle tonicity was reduced from 3.5 ± 0.2 pre-operation to 1.5 ± 0.5 post-operation,hence their movement had been improved.Conclusion SPR is an effective method for treatment of non-cerebral lower limb spasticity.It can remit the spasticity and muscle tonicity,and then it may improve the gait.
