【摘要】：目的:探讨前交叉韧带(anterior cruciate ligament,ACL)断裂患者步行时足底压力时间特征,为康复评定和运动训练提供参考依据。方法:应用footscan R足底压力测量系统,对64例单侧ACL断裂患者的动态足底压力进行对照研究。分析ACL断裂侧、未伤侧步行时支撑相时间参数(足-地接触时间及其足跟触地阶段、前足触地阶段、全足支撑阶段和前足蹬离阶段的百分比)的5次重测信度及其双侧差异。结果:上述各参数5次重测信度的组内相关系数均大于0.79。ACL断裂侧、未伤侧的足-地接触时间分别为662ms、668 ms(t=2.967,P=0.004),足跟触地阶段分别为8.15%、8.79%(t=2.940,P=0.005),全足支撑阶段分别为35.33%、39.29%(t=4.66,P=0.000);而前足蹬离阶段分别为46.62%、42.66%(t=-4.660,P=0.000)。结论:ACL断裂后步行时的动态足底压力时间参数重测信度良好,ACL断裂侧的足-地接触时间、足跟触地阶段和全足支撑阶段显著缩短,而前足蹬离阶段显著延长。
[Abstract]:Objective: to investigate the time characteristics of plantar pressure during walking in patients with anterior cruciate ligament (anterior cruciate ligament,ACL) rupture and to provide reference for rehabilitation evaluation and exercise training. Methods: the dynamic plantar pressure of 64 patients with unilateral ACL rupture was studied by footscan R plantar pressure measurement system. The time parameters of support phase (foot-ground contact time and the percentage of heel contact phase, front foot contact stage, full foot support stage and forefoot pedal phase) of ACL fault side and uninjured side walking were analyzed and their bilateral differences were analyzed. Results: the correlation coefficients of the above parameters were higher than those of the 0.79.ACL fault side. The contact time between foot and ground of the uninjured side was 662 ms (t0. 967 P0. 004), and the heel contact time was 8. 15 in the contact phase of the heel. 8.79% (t = 2.940), 39.29% (t = 4.66), respectively, and 35.33% (t = 4.66) in the whole foot support stage. However, 42.66% (t ~ (-4.660) P ~ (0.000) were used in the pedal stage of the anterior foot, and 46.62% (t ~ (-4.660) P ~ (+). Conclusion: the time parameters of dynamic plantar pressure during walking after ACL fracture have good reliability. The contact time between foot and ground at the side of ACL fracture, the contact time between foot and ground, the contact phase of heel and the whole foot support phase are shortened significantly, while the pedal stage of front foot is prolonged significantly.
