连续超声波治疗脑卒中后腓肠肌痉挛的疗效观察

Observation of curative efficacy of continuous ultrasonic wave therapy on post-stroke gastrocnemius spasticity

目的观察连续超声波治疗脑卒中后腓肠肌痉挛的疗效。方法26例脑卒中后腓肠肌痉挛的患者随机分为超声波组和对照组,两组在给予腓肠肌牵张治疗的基础上,超声波组采用超声治疗仪对患侧腓肠肌进行连续超声波治疗4周;比较治疗前后两组改良的Ashworth量表(mAS)评分、胫神经H反射的最大H波和M波比值(Hmax/Mmax)、腓肠肌肌束长度。结果超声波组治疗后mAS评分及Hmax/Mmax值较治疗前明显下降(均P<0.05),对照组治疗前后差异无统计学意义;与对照组比较,超声波组治疗后Hmax/Mmax值明显下降(P<0.05);两组治疗前后患侧腓肠肌肌束长度无明显变化。结论连续超声波治疗可以改善脑卒中后腓肠肌痉挛,但不能改变肌肉的机械特性。

Objective To observe the efficacy of continuous ultrasonic wave therapy on post-stroke gastrocnemius spasticity. Methods 26 patients with gastrocnemius spasticity after stroke were randomly divided into ultrasonic group and control group. The stretch therapy was used in the two groups,and the continuous ultrasonic wave therapy was added on ultrasonic group for 4 weeks. The scores of modefied Ashworth scale (mAS),the ratio of Hmax and Mmax,and the fascicle length of gastrocnemius pre and post treatment were ...
