This paper describes a kinetic and kinematic study on axillary crutches during one-leg swing-through gait. The primary objective is to evaluate the interplay of forces at the crutch and body interfaces and to relate them in the understanding of problems associated with the use of axillary crutches. Ten normal adult male subjects with simulated left leg impairment participated in the study. For data acquisition, the VICON kinematic system, a Kistler force plate and an instrumented crutch (with force transducers at the two upper struts close to the axillary bar and one near the crutch tip) were used. Results showed that the peak ground reaction force on the weight-bearing leg during lower limb stance increased by 21.6 percent bodyweight. The peak reaction force transmitted to the arm during crutch stance was 44.4 percent bodyweight. These increased loadings could be detrimental to patients with unsound weight-bearing leg and upper extremities respectively. When the crutches were used incorrectly, 34 percent bodyweight was carried by the underarm. This could cause undue pressure over the neurovascular structures at the axillary region.
本文描述了在单腿摆动通过步态期间对腋拐进行的动力学和运动学研究。主要目的是评估拐杖与身体界面处力的相互作用，并将它们与理解腋拐使用相关问题联系起来。十名模拟左腿受损的正常成年男性受试者参与了该研究。为了进行数据采集，使用了VICON运动学系统、一个奇石乐测力台和一个装有仪器的拐杖（在靠近腋杆的两个上支柱处以及靠近拐杖尖端处各有一个力传感器）。结果表明，下肢站立期间承重腿上的地面反作用力峰值增加了体重的21.6%。拐杖支撑期间传递到手臂的反作用力峰值为体重的44.4%。这些增加的负荷分别可能对负重腿不健康和上肢不健康的患者有害。当拐杖使用不当时，腋下承受了34%的体重。这可能会在腋窝区域的神经血管结构上造成过度压力。
