Abstract | The sequence of gait events and symetry of kinematic parameters between both lower limbs are compromised in below-knee amputees. In the present study the periods of double-limb support and the step length in below-knee amputees were investigated. The symmetry of the two periods of double-limb support occurring in each stride was obviously abnormal (ratio: 0.74) among temporal and distance parameters. The time of double-limb support (0.211+-0.05 seconds) measured from heel-strike of the amputated leg until toe-off of the normal leg was significantly longer (p=0.011) when compared with the contralateral leg (0.173+-0.04 seconds). The step length of the normal leg (0.709+-0.07 m) was significantly (p=0.045) shorter than that of the amputated leg (0.752+-0.08 m). Most of these differences between measured kinematic parameters can be explained by the limited ability of the prosthesis ankle-foot component to reproduce the normal functions of both footh and ankle. | |
