摘要 目的筛选直肠电刺激(RPES)治疗脊髓损伤后痉挛的最佳参数组合。方法应用正交表获得不同的RPES参数组合。10例肌张力2级以上的脊髓损伤患者,每例患者每次接受一种RPES参数组合治疗,直至完成所有参数组合。每次治疗前后分别评价患者的肌张力、阵挛、反射。采用正交设计方差分析对患者治疗前后差值进行分析。结果刺激强度10 mA、刺激频率3/min、刺激时间15 min时对肌张力的缓解最为明显;刺激强度10 mA、刺激频率4/min、刺激时间10 min对反射的缓解最明显;刺激强度40 mA、刺激频率2/min、刺激时间15 min对阵挛的缓解最明显;刺激强度10 mA、刺激频率2/min、刺激时间15 min对综合痉挛指数的缓解最明显。结论刺激强度对肌张力、反射和痉挛指数的影响较大,刺激频率对阵挛的影响较大。缓解单项指标的最佳刺激参数不一定是综合缓解痉挛的最佳刺激参数,应针对患者的不同需要选择参数组合。 Objective To screen the optimal parameters of rectal probe electrostimulation(RPES) to release spasticity after spinal cord injury.Methods 10 patients with muscular tension more than 2 level of the modified Ashworth scale after spinal cord injury received the RPES in 9 parameters combinations from orthogonal array,every patient underwent a combination per day.Their muscular tension,clonus and reflex were recorded before and after each treatment.The varieties were analyzed with orthogonal design variance analysis.Results The optimal parameter for muscular tension was 10 mA,3 /min,15 min;for reflex: 10 mA,4 /min,10 min;for clonus: 40 mA,2 /min,15 min;spasm score: 10 mA,2 /min,15 min.Conclusion The stimulus intensity most affects the muscular tension,reflex and spasm score,and the frequency of stimulation most affects the clonus.The parameter components were separately for muscular tension,reflex,clonus and spasm score.
