摘　　要：目的:观察和分析足下垂患者穿戴踝足支具(AFO)前后对下肢稳定性、负重能力、步行中膝、踝关节活动的影响。方法:20例足下垂患者(男14例,女6例),其中右侧足下垂者9例,左侧足下垂者13例。患者中有6例需在辅助下行走,14例已具备独立行走的条件。对所有患者分别在穿戴和不穿戴踝支具状态下进行步行能力、下肢活动能力、身体平衡功能测定。其中5例患者在穿戴支具1个月左右进行步态分析。结果:穿戴AFO后即刻患者的步行速度和步幅影响与穿戴支具前比较无显著差异(P>0.05);踏车时间和上楼的速度比不戴支具有明显提高(P<0.05),而起蹲、下楼时间、足抬高距离无显著差异(P>0.05);穿戴AFO对患肢负重无明显改善(P>0.05),但可使患者身体左右的稳定性及患腿前后的稳定性有明显改善(P<0.05);步态分析结果发现,5例患者穿戴支具前后患侧下肢垂直峰力矩、步速无明显影响(P>0.05);穿戴AFO后患侧膝关节在步行周期中最大伸膝度数较不穿支具明显减少(P<0.05);患侧踝关节在步态周期中最大趾屈度数较不穿支具明显减少(P<0.01)。结论:AFO对下肢功能的影响主要表现在改善足下垂和膝过伸程度;增强身体稳定性及患侧下肢稳定性;穿戴AFO对患者下肢日常功能活动无明显影响;对患者即刻和1个月以后的步速、步幅、患腿负重能力的改善不明显?Objective: To observe and analysis the effect of ankle foot orthosis(AFO) on lower extremity stability, weight loading ability and range of joint motion(ROM) of the knee and ankle during walking. Method:Twenty patients with foot drop had taken part in this study.There were 6 cases with assist walking and 14 cases with independent ambulation. All patients received evaluation of walking ability,lower extremity activity ability and balancing function of body in wearing or unwearing AFO. Five cases wearing AFO received gait analysis about 1 month later.Result:The main lower extremity capability of the patients(such as walking speed, step width and downstairs time,etc) wearing AFO hadn′t improved greatly(P>0.05); The patients′ balancing stability of body wearing AFO had improved greatly(P<0.05); The ROM of the knee and ankle of the patients during walking had been improved(P<0.05,P<0.01).Conclusion:An effect of AFO on lower limb function of the patients is to improve foot drop and knee excessive extension,to increase balancing stability of the body and lower extremity. Changes in ADL and gait weren′t found.Author′s address Department of Rehabilation Medicine, First Affiliated Hospital of Nanjing Medical University, Nanjing,210029
