摘要:
Above-knee (AK) amputees generally walk slower than normal subjects. To understand why this occurs, the kinetics (forces and moments) of walking, at different walking speeds, must be examined. The purpose of this study was to determine the effect of walking speed on stride length, stride and swing times, the knee and hip displacement and torque patterns, and the roles of the gravitational forces and interactive moments associated with thigh motion. Three subjects were filmed walking at three self-selected walking speeds (slow, natural, fast). The swing phase was analyzed in detail using the inverse dynamics approach. As walking speed increased, the stride length increased while stride and swing times decreased. The maximum knee flexion and initial hip .flexion peaks increased as walking speed increased. As walking speed increased, the knee flexor torque during terminal swing increased, and this was necessary to slow the leg down in preparation for the subsequent weightbearing stage. The principle moment limiting knee flexion was the gravitational moment, which was assisted by the interactive moments associated with thigh acceleration and velocity (L-AT and L-VT). The hip muscular torque pattern was characterized by four phases—initial flexor and extensor, final flexor and extensor. The initial extensor torque decelerated the thigh, which in turn contributed to the term L-AT. L-AT assisted in accelerating the leg and resisted knee flexion and initiated knee extension. The final hip extensor torque slowed down the thigh and maintained the knee in extension, through the term L-AT in preparation for footstrike.
