摘要
目的:探讨运动想象对脑卒中患者步态的时间与空间参数和步行能力的影响。方法:选择34例慢性偏瘫患者分为治疗组(n=18)和对照组(n=16),采用运动解析系统评测运动想象前后及12周随访时的最大步行速度、步态时相和时间-空间参数。结果:运动想象治疗前后及第12周随访时,最大步行速度、步态时间-空间参数、时相参数和步态不对称指数差异均有显著性意义(P<0.01),治疗6周后与对照组比较差异也有显著性意义(P<0.05)。PostHoc检验,治疗前与12周随访时比较,步频、步幅、健侧步长和不对称指数差异有显著性意义(P<0.05);与治疗第3周比较,所有评价指标差异有显著性意义(P<0.05);与第6周比较,除双腿支撑期外,其他参数差异均有显著性意义(P<0.05);治疗第6周和12周随访时比较,只有不对称指数差异有显著性意义(P<0.01)。结论:运动想象可以改善偏瘫步态时间-空间和时相参数,矫正步态不对称,提高步行能力。
Objective：To quantitatively analyze the effect of motor imagery（MI） on maximum walking speed and gait parameters and to explore the use of MI practice to improve walking ability and gait stability in post-stroke patients with hemiparesis.Method：A total of 34 patients with chronic hemiparesis after stroke who could walk at least 10m without assistance were selected in this study.They were divided into treatment group（n=18） and control group（n=16）.The treatment group was treated with MI,the control group had non MI.The maximum walking speed,gait temporaldistance parameters and gait asymmetry index were examined using the motion analysis system.Result：After MI practice and at the 12th week follow-up the positive effects on hemiplegic gait parameters and asymmetry index,improving maximum walking speed were significant（P〈0.01）.After 6-week in tervention there were significant differences between treatment group and control group on maximum walking speed,relative double-support time（P〈0.05）,and the hemiplegic gait parameters,asymmetry index（P〈0.01）.Pair wise comparisons suggested there were significant differences between before MI treatment and the 12th week follow-up only on the stride length,step-length of nonparetic limb and gait asymmetry index（P〈0.05）.There were significant differences between before MI treatment and after 3-week intervention on all parameters,moreover,there were significant differences between before MI treatment and after 6-week intervention except the absolute double-support time（all P〈0.05）.There was significant difference between after 6-week intervention and the 12th week follow-up only on the gait asymmetry index（P〈0.01）.Conclusion：The outcomes suggested that MI might be useful for the enhancement of walking ability and gait stability in patients following stroke.Moreover,improvement were mainly in temporal-distance gait variables and gait asymmetry index.
