下肢康复机器人LR2训练对偏瘫患者下肢肌痉挛和ADL能力改善的疗效观察

A study on the antispasticity effect and ADL of leg rehabilitation robot(LR2) in the hemiplegia patients

目的:探讨分析下肢康复机器人LR2训练后,偏瘫患者肌痉挛和ADL能力的改善情况。方法:将40例脑卒中偏瘫患者按随机数字表法分为实验组和对照组,每组各20例。试验组在常规康复治疗的同时,运用LR2进行下肢康复训练,每天1次,每次30min,共治疗6周;对照组仅予以常规康复治疗,每天1次,每次30min,共治疗6周。在入组时、6周后分别采用改良Ashworth痉挛评定量表、简式Fugl-Meyer运动量表下肢部分和改良Barthel指数评定法对两组患者下肢肌张力、下肢运动功能及生活自理能力进行评定,比较两组的疗效。结果:两组患者下肢肌张力较治疗前均有明显降低(P<0.05),下肢运动功能及日常生活自理能力较治疗前有明显提高(P<0.05),且试验组疗效明显优于对照组(P<0.05)。结论:下肢康复机器人LR2对脑卒中偏瘫患者下肢肌痉挛有显著的改善作用,可提高患者下肢运动功能及生活自理能力,且近期疗效优于常规的康复治疗。

Objective：To observe effects of lower-limb rehabilitation robots on the lower limb spasticity, motor function and ADL of hemiplegic patients after stroke. Method： 40 cases of hemiplegic patients were randomly allocated to experiment and control groups （n=20 in each）.The experiment group received training assisted by a leg rehabilitation robot LR2 for 30 min once daily for 6 weeks in addition to conventional treatments. The control group was given conventional treatments once daily for 6 weeks. Their lower limbs spasticity, motor function and ADL were assessed with the modified Ashworth rating scale（MAS）, Simplified Fugl-Meyer Movement Scale （FMA） and Modified Barthel Index assessment method （MBI） before and after training. Result：After treatment, the lower limb spasticity was significantly lowered （P〈0.05）, lower limb motor function and ADL were significantly improved （P〈0.05）, and the experimental group was significantly better than the control group （P〈0.05）. Conclusion： Leg rehabilitation robot LR2 can lower the spasticity of lower limb muscle and improve lower limb motor function and the ability of daily living in stroke patients, and the short term effect is better than conventional rehabilitation.
