目的 观察运动想象疗法对脑卒中偏瘫患者下肢运动功能恢复的影响。方法 将32例脑卒中偏瘫患者分为实验组（n=16）和对照组（n=16），两组均采用常规康复训练，实验组在常规康复训练结束后进行运动想象疗法(15 min/次，1次/日)。两组均经过3个阶段：1～3周为第一阶段，4～5周为第二阶段（治疗间歇期，即不进行系统正规的康复训练及运动想象疗法），6～8周为第三阶段。采用Fugl-Meyer运动功能评分(FMA)下肢部分和功能独立性测定(FIM)中运动功能部分的转移和行走评定治疗结果。结果 两组患者治疗前FMA和 FIM评分差异无统计学意义（P>0.05），两组在3个阶段治疗后上述评分较治疗前均有明显提高（P<0.01），第二阶段治疗前后差异无统计学意义；各个阶段实验组FMA和FIM评分均较对照组显著提高，差异有统计学意义（P<0.01）。结论 运动想象疗法结合常规康复训练可提高脑卒中偏瘫患者下肢运功功能及日常生活能力。

Objective To investigate the effect of motor imaginary therapy on lower limb motor function in hemiplegic patients after stroke. Methods Thirty-two hemiplegic patients after stroke were randomly divided into experiment group (n=16) and control group (n=16). Conventional rehabilitation was conducted in both group, and motor imaginary therapy was performed in experiment group after conventional rehabilitation (once a day, 15 min for each time). The treatment was made up of three stages: first stage, from the first week to the third week; second stage, from the fourth week to the fifth week (systemic conventional rehabilitation and motor imagery therapy were not performed during this period); and the third stage, from the sixth week to the eighth week. The therapeutic outcomes were evaluated with Fugl-Meyer motor assessment (FMA) and functional independent measurement (FIM). Results There was no significant difference in FMA and FIM scores between two groups before treatment (P>0.05). Compared with those before treatment, the FMA and FIM scores significantly increased after each stage of treatment in both groups (P<0.01), while there was no significant difference between FMA and FIM scores before the second stage of treatment and those after the second stage of treatment. The FMA and FIM scores in experiment group were significantly higher than those in control group in each stage of treatment (P<0.01). Conclusion Motor imaginary therapy combined with conventional rehabilitation can improve the lower limb motor function and activities of daily living in hemiplegic patients after stroke.
