Using a Force Plate the gait cycle for one leg swing-through gait of ten normal subjects on Canadian crutches was monitored, and a composite diagram of forces on the lower limb and both crutches was produced. In addition the relationship of the stance and swing phase for both the lower limb and crutches was studied and the percentage of these phases and their overlap included on the composite diagram. The average maximum vertical ground reaction to the leg was 1.32 body weight, 16 per cent higher than that reported for normal walking. The horizontal force on the lower limb in the direction of walking was 0.35 body weight, compared to 0.15 for normal walking. Vertical ground reaction to crutches was on average 0.54 body weight on the side of the landing leg and 0.51 on the contralateral side. Horizontal ground reaction on the crutches at right angles to the direction of ambulation was 0.09 body weight on the right and 0.08 on the left. The results were considered to indicate caution in the prescription of one leg swing-through gait in subjects with diseased bone and joints in the lower limb.
使用测力板监测了十名正常受试者在加拿大拐杖辅助下单腿摆动通过步态的步态周期，并绘制了下肢和双拐受力的综合图表。此外，还研究了下肢和拐杖支撑期与摆动期的关系，并将这些阶段及其重叠部分的百分比纳入综合图表。腿部平均最大垂直地面反作用力为1.32倍体重，比正常行走时报告的数值高16%。下肢在行走方向上的水平力为0.35倍体重，而正常行走时为0.15倍体重。落地侧拐杖的垂直地面反作用力平均为0.54倍体重，对侧为0.51倍体重。与行走方向成直角的拐杖水平地面反作用力右侧为0.09倍体重，左侧为0.08倍体重。结果表明，对于下肢患有骨关节疾病的受试者，在开具单腿摆动通过步态的处方时应谨慎。
