摘　　要：目的:观察佩戴踝足矫形器(AFO)对脑卒中患者步行能力改善的程度。方法:脑卒中偏瘫患者32例,给予佩戴50S1动态踝足矫形器7d后,采用三维步态分析系统评测佩戴AFO前后的步态空间域参数和步态时间域参数。结果:佩戴7d后,脑卒中患者步态空间域参数中平均步幅宽患、健侧均较佩戴前下降(P<0.05),平均步幅长、步伐长和平均步向角患、健侧均较佩戴前增大(P<0.05,0.01);步态时间域参数中步速、步频和双支撑相百分比患侧、健侧均较佩戴前明显增加,(P<0.01),单支撑相和摆动相百分比患侧较佩戴前明显增加、健侧较佩戴前下降(P<0.01)。结论:佩戴AFO可以改善脑卒中患者步态的稳定性,患、健侧的步速、步频均明显提高,并且佩戴后即刻发挥作用。Objective：To observe the effects of the ankle-foot orthosis （AFO） on the recovery of the walking ca pacity of patients With stroke hemiplegia. Methods：We randomly selected 32 cases of chronic stroke hemiparesis. Af ter using 50S1 AFO for 7 days,we adopted 3 D gait analysis system on these patients to evaluate and contrast the gait parameters in the spatial domain and time domain before and after using AFO. Results：After using AFO for 7 days,we observed that one of the spatial parameters,the average stride width of both injured and uninjured sides was decreased significantly （P〉0.05）. On the contrary,the average stride length, pace length and step angle of both in jured and uninjured sides were increased dramatically （P〈0. 05）. The time domain parameters, including stride pace,stride frequency and double support status of both injured and uninjured sides were raised significantly （P〈 0.01）. The single-support status and sway status of injured sides were raised,and those of the uninjured sides de clined （P〈0. 01）. Conclusion： Adopting AFO on hemiplegic patients can improve their stride stability, and increase their stride pace and stride frequency significantly. The improvement took place immediately after wearing AFO.
