Multiple displacement patterns, stride dimensions, and temporal components during slow, free-speed, and fast walking were compared in the same seven above-knee amputees using prostheses with constant-friction knee components and using hydraulic swing-control knee components. During walking with the hydraulic-type prostheses, the amputees showed a wider range of walking speeds, improvement in the equality of the durations of successive swing and stance phases, and greater uniformity of forward progression. Improvements toward normal were also seen in several of the displacement patterns of the prosthetic limb during walking with the hydraulic knee. Several gait abnormalities persisted with both types of prostheses.
使用带有恒定摩擦膝关节组件的假肢和液压摆动控制膝关节组件，对上述七名相同的膝上截肢者在慢速、自由速度和快速行走过程中的多种位移模式、步幅尺寸和时间成分进行了比较。在使用液压型假肢行走时，截肢者表现出更宽的行走速度范围、连续摆动和站立阶段持续时间的均等性得到改善，以及向前推进的更大均匀性。在使用液压膝关节行走时，假肢肢体的几种位移模式也显示出向正常的改善。两种类型的假肢都存在一些步态异常。
