摘　　要：目的:通过对肌力失衡性膝内翻患者进行开闭链运动干预,探究两种运动模式的治疗效果及对患者步态和足底压力的影响。方法:运用Zebris步态分析系统对14名肌力失衡性膝内翻患者进行步态参数测量,观察两组患者的支撑相、摆动相、双支撑阶段数据和足底压力。研究结果:两组膝间距、Q值、腿长均与正常下肢数据差距缩小,P<0.05,实验结果呈现显著性差异。两组受试者的三足区域压力显示:开链组和闭链组运动干预前后,足部三区的足跟到前掌时间变化、最大力值、最大压力值、时间最大力值、接触时间均有变化,其中开链组前足、中足、足跟的最大力值,中足和足跟的最大压力值,前足的时间最大力值占比,足跟的接触时间百分比差异性显著(P<0.05),具有统计学意义,闭链组前足、足跟的最大力值,中足、足跟的最大压力值和时间最大力值百分比,前足和足跟的接触占比差异性显著(P<0.05),具有统计学意义。三足区的其余参数干预前后有差异,但P值大于0.05,不具有统计学意义。研究结论:开练运动和闭链运动对膝内翻患者的步态时相和足底压力均有改善,但两组干预模式优劣暂无定论。The objective of this paper is to explore the therapeutic effect of two exercise modes and the impact on the patient's gait and foot pressure by conducting open and closed-chain movement intervention for patients with muscle imbalanced knee inturn.Methods:the Zebris gait analysis system was used to measure the gait parameters of 14 patients with muscle imbalanced knee inturn,and observe two support phase,swing phase,double support stage data and sole pressure of the patients in the group.Results:the gap between the knee spacing,Q value and leg length of the two groups and the normal lower limb data was narrowed,P<0.05,and the experimental results showed a significant difference.The pressure of the three-legged area of the two groups of subjects shows:before and after the movement intervention of the open chain group and the closed chain group,the heel to the front palm time change,maximum force value,maximum pressure value,time maximum force value and contact time in the three areas of the foot area of the foot have changed.Among them,the maximum force value of the forefoot,middle foot and heel in the open chain group,and the maximum pressure of the middle foot and the heel.value,the proportion of the maximum force value of the forefoot,the difference in the contact time percentage of the heel is significant(P<0.05),which has statistical significance.The maximum force value of the forefoot and the closed-chain group,the maximum pressure value of the midfoot and the maximum force value of the heel,and the percentage of the maximum force value of the forefoot,and the contact proportion of the forefoot and the heel are significant(P<0.05),which is of statistical significant.The rest of the parameters in the tripal area are dfferent before and after intervention,but the P value is greater than 0.05,which is not statistically significant.Conclusion:the opening exercise and closed-chain movement improve the gait phase and foot pressure of knee invert patients,but the advantages and disadvantages of the intervention mod
