摘要：

背景：目前关于前交叉韧带重建后训练对患者静态本体感觉或平衡的影响研究较多，对动态步行稳定性的研究较少。
目的：利用三维步态分析系统对前交叉韧带重建后患者本体感觉训练后步行的稳定性进行分析。
方法：单侧前交叉韧带重建患者32例，重建后3~6个月，可独立步行，膝关节无明显肿胀疼痛。所有患者本体感觉训练前及训练2个月后进行步态分析。
结果与结论：本体感觉训练后患者步频(P < 0.01)、步长(P < 0.01)、步速(P < 0.05)、患足廓清地面最大距离(P < 0.001)均较训练前明显改善。行走时，骨盆摆动、上身摆动三维扑捉图像与训练前相比更对称，更协调。提示利用三维步态分析系统比较本体感觉训练的效果，对评估步行过程中不自觉的关节稳定和姿势、平衡的调整和维持具有重要意义。

Abstract:

BACKGROUND: There are many studies on the effects of training on static proprioception or balance after reconstruction of anterior cruciate ligament, but few on the stability of walking.
OBJECTIVE: To study the effects of proprioception enhancement training on walking stability after reconstruction of anterior cruciate ligament by three-dimensional gait analysis.
METHODS: Thirty-two patients underwent unilateral anterior cruciate ligament reconstruction. At 3-6 months after operation, patients could walk themselves, and no significant swelling and pain of knee occurred. Gait analysis was examined in all patients before and after 2 months proprioception training.
RESULTS AND CONCLUSION: The gait velocity (P < 0.05), stride length (P < 0.01), cadence (P < 0.01) and the maximum clearance distance of the affected foot (P < 0.001) in patients were significantly improved after training compared with those before training. Three-dimensional gait analysis showed that the sway of the trunk and pelvis was more symmetric and coordinated when walking. The three-dimensional gait analysis system is very important to evaluate the effect of proprioception training on unconscious stability of joint and maintenance of posture and balance.
