肌电生物反馈治疗脑卒中恢复期后老年患者踝关节运动功能和认知功能的疗效观察

目的探讨结合常规康复训练，肌电生物反馈治疗（EMGBF）对脑卒中恢复期后老年患者踝关节运动功能和认知功能的疗效。方法选取病程4～6m的首次脑卒中恢复期后老年患者80例，随机分成EMGBF组和对照组，每组40例。两组患者药物治疗相同，EMGBF组患者采用常规康复训练结合EMGBF；对照组患者采用常规康复训练，治疗6m。分别采用Lovett分级评定量表、改良Ashworth量表、下肢Brunnstrom分级量表、MMSE量表进行测试，丁治疗前、后评估患者的踝关节运动功能和认知功能。结果治疗6m后，对照组与EMGBF组各评估的结果均有不同程度的改善，与治疗前比较患者Lovett分级评定昔表、下肢Brunnstrom分级量表的评估结果差异均有显著性意义（p〈0．05）；但EMGBF组患者Lovett分级评定量表、下肢Brunnstrom分级量表的评估结果均优丁对照组（P〈0．05）；随访6m后，EMGBF组改良Ashworth量表、下肢Brunnstrom分级量表的评估结果均优丁对照组（P〈0．05）。结论常规康复训练结合EMGBF能更有效地改善脑卒中恢复期后老年患者踝关节运动功能和认知功能。

Effect of Electromyographic biofeedback on the movement and cognition of ankle joint of elderly patients after stroke

Objectiv To investigate the effect of Electromyographic Biofeedback on the movement and cognition of ankle joint after recovery phase of stroke in the elderly patients. Methods 80 consecutive cases of the elderly patients with 4 to 6 months after stroke for the first time were researched, which were randomly divided into study group and control group, 40 cases each group. All the patients after the same medical treatment have regular rehabilitation therapy for six months, but the study group received electromyographic biofeedback training （EMGBF） in addition. Lovett grading scale, the improved Ashworth scale, limb Brunnstrom stages, MMSE scale after six-month treatment and the six-month follow up were evaluated. Results The significant progress of ankle function was detected in the postoperative weeks com- pared to the preoperative stage, there was significant difference in Lovett grading scale and limb Brunnstrom stages in EM- GBF group （P〈0.05） after six-month treatment and the six-month follow up. Conclusions The Electromyographic bio- feedback training based on regular rehabilitation therapy can effectively improve the movement and cognition of ankle joint in the elderly patients after recovery phase of stroke.
