【摘要】：目的研究不同硬度楔形鞋垫在步行状态下对膝关节内翻力矩的影响。方法 15名健康成年男性受试者穿着不同硬度楔形鞋垫进行步态测试,通过光学运动捕捉系统和地面测力板收集运动学和动力学数据,经Visual3D软件计算得出膝关节内翻力矩,分析在3种不同步行状况下(仅穿鞋、鞋中放入软、硬楔形鞋垫)膝关节内翻力矩峰值的差异。结果与较软的楔形鞋垫相比,较硬的楔形鞋垫可使膝关节内翻力矩的第1个峰值降低9.3%,第2个峰值降低9.7%,差异具有统计学意义。结论楔形鞋垫增加一定的硬度能更多降低膝关节内侧间室的压力,减轻关节面的磨损,从而可能缓解膝关节炎症状。
[Abstract]:Objective to study the effect of wedge insoles with different hardness on the varus moment of knee joint on foot.Methods Fifteen healthy adult male subjects wore wedge-shaped insole with different hardness for gait test. Kinematics and dynamics data were collected by optical motion capture system and ground force plate. The knee joint varus moment was calculated by Visual3D software.The difference of the peak value of varus moment of knee joint in three different walking conditions (only wearing shoes and putting soft and hard wedge insoles in shoes) was analyzed.Results compared with softer wedge insole, the first peak value of knee joint varus moment was decreased by 9.3 and the second peak value was decreased by 9.7%. The difference was statistically significant.Conclusion increasing the hardness of wedge insole can reduce the pressure of medial compartment of knee joint and reduce the wear of articular surface, which may relieve the symptoms of knee arthritis.
