【摘要】：目的获取青年男性踝关节外侧韧带损伤者行走时踝关节的运动学和动力学参数,探讨损伤者行走步态的生物力学特性。方法采用Qualisys MCU500三维运动影像捕捉系统与Kistler三维测力台,对踝关节外侧副韧带损伤者与健康者各15名的行走步态进行三维同步测试。结果踝关节外侧副韧带损伤者竖直方向的地面反力变化平缓;在支撑时相中前期,损伤者前后方向的力要比健康者大;在步态周期的60%之前,损伤者左右方向的力明显大于健康者。损伤者关节跖屈力矩变化与健康者相似,患侧外翻力矩、外旋力矩最大,损伤者健侧输出功率最大。结论损伤者踝关节的稳定性下降,行走时步态异常,为减少患侧负荷,健侧出现代偿效应,足着地瞬间加速过度到垂直支撑时相。本研究为预防踝关节以及损伤后的临床治疗以及康复训练等提供一定的理论参考。
[Abstract]:Objective to study the biomechanical characteristics of walking gait of young male patients with lateral ligament injury of ankle joint. Methods Qualisys MCU500 three-dimensional motion image capture system and Kistler three-dimensional dynamometer were used to measure the walking gait of 15 patients with lateral collateral ligament injury and 15 healthy subjects. Results the lateral collateral ligament injury of the ankle showed a gentle change of the vertical ground reaction force; in the early phase of the support phase, the force in the front and back direction of the injured person was greater than that in the healthy one; before 60% of the gait period, the force in the front and back direction of the injured person was greater than that in the healthy one. The force on the left and right direction of the injured person was obviously greater than that of the healthy person. The change of the joint metatarsal flexion moment in the injured group was similar to that in the healthy one. The inflection moment and the external rotation moment of the injured joint were the largest and the output power of the healthy side was the largest. Conclusion the ankle stability of the injured patients decreased and the gait was abnormal during walking. In order to reduce the burden of the affected side, the healthy side had modern compensatory effect, and the foot ground was accelerated to the phase of vertical support. This study provides a theoretical reference for the prevention of ankle joint and post-injury clinical treatment and rehabilitation training.
