摘　　要：背景:深层肌肉刺激疗法是一种局部振动疗法,可有效缓解因牵拉或劳累所致损伤、乳酸堆积,或筋膜粘连造成的疼痛和功能受限,但其对慢性非特异性腰痛作用的研究报道相对不足。目的:探讨深层肌肉刺激疗法对慢性非特异性腰痛患者腰肌表面肌电变化、步态时空与动力学参数特征的影响。方法:选取2019年2月至2020年6月在盐城市第一人民医院就诊的102例慢性非特异性腰痛患者作为研究对象,采用随机单盲对照试验设计,按随机数字表法分为2组,各51例。对照组予以传统腰椎节段稳定性训练,观察组在传统腰椎节段稳定性训练基础上,给予深层肌肉刺激疗法。统计两组临床疗效、治疗前及治疗1,6个月疼痛程度、腰椎功能、腰肌表面肌电变化、步态时空与动力学参数特征、生活质量及不良反应。结果与结论:观察组总有效率(96%)高于对照组(82%)(P<0.05),观察组治疗1,6个月后目测类比评分均低于对照组(P<0.05),多裂肌、回旋肌前屈60°、外展90°、后伸45°时最大肌电值明显高于对照组(P<0.05),步长对称指数、足偏角对称指数、站立相对指数、初始双支撑垂直地面反作用力、单支撑相垂直地面反作用力、终末双支撑垂直地面反作用力均低于对照组(P<0.05),Oswestry功能障碍指数低于对照组(P<0.05),SF-36评分高于对照组(P<0.05);观察组和对照组不良反应发生率分别为3.9%(2/51),5.9%(3/51),差异无显著性意义(P﹥0.05)。结果表明,深层肌肉刺激疗法有助于减轻慢性非特异性腰痛患者的疼痛,恢复腰椎功能并改善步态。BACKGROUND:As a local vibration therapy,deep muscle stimulation therapy can effectively relieve the pain and functional limitation caused by traction or fatigue,lactic acid accumulation,or fascia adhesion.However,less is reported on its effect on chronic non-specific low back pain.OBJECTIVE:To investigate the effect of deep muscle stimulation therapy on the changes of psoas surface electromyography as well as spatiotemporal and kinetic gait parameters in patients with chronic non-specific low back pain.METHODS:This was a single-blind randomized controlled trial.A total of 102 patients with chronic non-specific low back pain admitted to Yancheng No.1 People’s Hospital from February 2019 to June 2020 were enrolled and randomly divided into two groups(n=51 per group):a control group and an observation group.Patients in the control group received a traditional lumbar stabilization exercise,and patients in the observation group received deep muscle stimulation therapy based on the lumbar stabilization exercise.Clinical efficacy,pain degree,lumbar spine function,psoas surface electromyography changes,spatiotemporal and kinetic gait parameters,quality of life,and adverse reactions were statistically analyzed before treatment,1 and 6 months after treatment.RESULTS AND CONCLUSION:The overall efficiency of the observation group(96%)was higher than that of the control group(82%;P<0.05).After 1 and 6 months of treatment,the visual analog scale scores of the observation group were lower than those of the control group(P<0.05).The maximal electromyographic value of the multifidus and musculi rotatores at 60°anteflexion,90°abduction,and 45°extension was significantly higher in the observation group than the control group(P<0.05).The step length symmetry index,foot deflection angle symmetry index,standing relative index,initial double support vertical ground reaction force,single support phase vertical ground reaction force,and terminal double support vertical ground reaction force were lower in the observation group than t
