摘要：

      摘要 目的：研究四肢联动训练对脑卒中患者运动功能和下肢表面肌电的影响，并探讨其可能的作用机制。 方法：选取中山医院康复医学科住院的脑卒中偏瘫患者32例，随机将其分为治疗组和对照组，每组16例。对照组为常规康复训练组，而治疗组为四肢联动训练组，两组均进行为期4周的治疗，分别采用Berg评分（BBS）、起立行走试验（TUG）、改良Barthel指数（BI）、静态平衡仪测试和表面肌电图进行评估。 结果：干预后治疗组中Berg评分、腓肠肌和股直肌的iEMG较对照组有显著提升（P<0.05），而动摇总轨迹长、X轴最大动摇径和踝跖屈CR则更低于对照组（P<0.05）。 结论：四肢联动训练能够提升脑卒中患者伸膝肌群和踝关节控制能力，并有效改善患者的运动和平衡功能。

Abstract:

      Abstract Objective： To explore the effects of limb linkage training on motor function and lower limb surface electromyography in stroke patients， and investigate its possible mechanisms. Method： Thirty-two stroke hemiplegic patients admitted to the Rehabilitation Medicine Department of Zhongshan Hospital were selected and randomly divided into the treatment group and the control group， with 16 cases in each group. The control group received routine rehabilitation training， while the treatment group received limb linkage training. Both groups were treated for 4 weeks and evaluated by the Berg Balance Scale(BBS), Timed Up and Go Test(TUG), modified Barthel index(MBI), static balance instrument test, and surface electromyography. Result： After intervention， the BBS score and iEMG of gastrocnemius and rectus femoris muscles in the treatment group were significantly improved compared to the control group （P<0.05）， while the total trajectory length of shaking， maximum X-axis shaking diameter， and ankle plantar flexion CR were lower than those in the control group （P<0.05）. Conclusion： Limb linkage training can enhance the knee extensor muscle group and ankle joint control ability of stroke patients， and effectively improve their motor and balance functions.
