| 目的 探讨镜像疗法对脑卒中偏瘫患者下肢肌肉表面肌电的影响。 方法 将62例脑卒中偏瘫患者按分层随机分组法分为镜像组和对照组，每组31例。两组患者均进行常规康复训练，镜像组在此基础上增加镜像疗法。于治疗前和治疗4周后（治疗后），采用无线表面肌电系统采集并分析患侧股直肌、股二头肌、胫骨前肌的最大收缩力量（MVC）及随意收缩时的积分肌电值（iEMG）、均方根值（RMS），比较上述指标治疗前、后的变化情况，评估训练效果。 结果 治疗前，两组患者患侧下肢胫骨前肌、股二头肌、股直肌的MVC、iEMG及RMS比较，差异均无统计学意义（P>0.05）。治疗后，两组患者患侧下肢胫骨前肌、股二头肌、股直肌的MVC、iEMG及RMS均较组内治疗前改善（P<0.05）。治疗后，与对照组比较，镜像组患者患侧下肢胫骨前肌、股直肌、股二头肌MVC、iEMG及RMS的提高幅度较大，差异有统计学意义（P<0.05）。 结论 镜像疗法能增强脑卒中偏瘫患者患侧下肢肌肉运动过程中运动单位的募集及同步化程度，增加参与运动的运动单位数量及放电总量，并促进下肢肌肉力量恢复。 |
| 英文摘要: |
| Objective To explore the effects of mirror therapy on the lower-limb muscles of hemiplegic stroke survivors. Methods Sixty-two hemiplegic stroke survivors were divided by stratified random grouping into a mirror group and a control group, each of 31. Both groups accepted routine rehabilitation training, while the mirror group was additionally provided with mirror therapy to train the non-paretic limb for 30 min per day, 5 days a week, lasting 4 weeks. Before and after the 4 weeks of training, integrated electromyography was performed and the maximum voluntary contraction force (MVC) of the tibialis anterior, rectus femoris and biceps femoris of the paretic limb were recorded and compared. Results Compared with before the training, the average root mean square values of the electromyographs and the average MVCs of all three muscles had improved significantly in both groups after training. Compared with the control group, the improvements were significantly greater in the mirror group. Conclusion Mirror therapy can promote the activation and synchronization of motor units, as well as increase the number discharging and the total discharge, promoting the recovery of muscle strength. |
