【摘要】 目的评价经皮神经电刺激(TENS)治疗脑卒中患者踝跖屈内翻的临床疗效,并探讨其作用机制。方法32例恢复期脑卒中患者,存在不同程度的踝跖屈内翻,随机分为TENS组和对照组各16例,在神经发育疗法、手法治疗以及配戴足托治疗的基础上,TENS组加用患侧胫前肌和腓骨长短肌的TENS治疗。于治疗前后用综合痉挛量表(CSS)、肌电图H反射评定腓肠肌的痉挛程度。结果治疗后,TENS组和对照组CSS评分都有明显降低,和治疗前相比均有统计学意义,TENS组CSS降低较对照组明显,但两组间差异无统计学意义；TENS组H反射波潜伏期延长、H/M降低,和治疗前相比差异有统计学意义,对照组无明显变化；目测TENS组患者的痉挛偏瘫步态得到明显改善。结论TENS能减轻脑卒中患者腓肠肌痉挛,有助于踝跖屈内翻和痉挛偏瘫步态的改善。更多还原

【Abstract】 Objective To evaluate the effects of TENS on metatarsus plantar flexion and inversion in stroke patients,and to explore its mechanism.Methods Thirty-two stroke patients with gastrocnemius spasticity were randomly divided into a control group (n=16) and a TENS group (n=16).All patients were treated with foot sup- ports,neurodevelopmental and manipulation therapies.In addition,the TENS group received TENS on the anterior tibialis,peroneus longus and brevis muscles.All patients were assessed in terms of their Chinese stroke scale(CSS) and H reflex scores before and after therapy.Results Compared with those in the control group,the H reflex scores in the TENS group were obviously decreased,while H reflex latency was prolonged and H/M was reduced. Gait in the TENS group was evidently improved.Conclusion TENS is an effective therapy to decrease gastrocnemi- us spasticity and to improve the gait of stroke patients.更多还原
