踝足矫形器对脑卒中患者躯体运动及其步行能力的影响

摘要目的：探讨踝足矫形器（AFO）对脑卒中患者躯体运动和步行能力的影响及其之间的相互关系。方法：20例可以独立步行10m以上的慢性偏瘫患者，采用三维步态分析系统评测佩戴AFO前后的最大步行速度及躯体运动学参数。结果：佩戴AFO前后最大步行速度、身体重心垂直和侧方运动、骨盆前后倾斜和旋转运动差异有显著性意义（P<0.01）；步行能力的提高与身体重心运动和骨盆旋转运动改善显著相关（P<0.01）。结论：佩戴AFO可以改善脑卒中偏瘫患者躯体运动的稳定性，并且与提高患者的步行能力相关。

Effects of ankle-foot orthosis (AFO) on trunk motion and walking capacity of hemiplegic stroke patients

AbstractObjective: To quantitatively analyze the effects of ankle-foot orthosis (AFO) on trunk motion and walking speed of hemiplegic stroke patients and investigate the correlation between the improvements in trunk motion and walking capacity. Method: The maximum walking speed, gravity center of body and pelvic movements were examined with and without AFO in twenty post-stroke hemiplegic patients using the three-dimensional motion analysis system. Result: The AFO had positive effects on hemiplegic gait parameters, improving walking speed, pelvic rotation and tilt, lateral and vertical movements of gravity center of body(P<0.01). There was significant correlation between the improvements in walking capacity and trunk motion (P<0.01). Conclusion: The AFO could compensate the instability of trunk motion of hemiplegic stroke patients. Moreover, the improvement in walking capacity was associated with the compensation for the instability of trunk motion.
