This investigation compared stance, swing, and double support times of a recent below-the-knee amputee (BKA) child's gait with the gait of normal children and with that of experienced BKA children. Kinematic data were collected for 11 normal children, 2 experienced BKA children, and a novice BKA child. Results indicated there were significant differences between the steps of prosthetic and nonprosthetic limbs and between normals and BKAs. Initially the gait of the novice BKA differed from that of experienced BKAs. After 94 days the gait of the novice BKA was not significantly different from that of the experienced BKAs. It was concluded that since the structure and function of the prosthetic limb is not the same as normal, (a) it may be appropriate for the BKA child to have an asymmetrical gait pattern, and (b) rehabilitation may be directed toward teaching the recent BKA child to walk more like experienced BKAs than like normal children.
本研究比较了一名近期接受膝下截肢（BKA）的儿童与正常儿童以及经验丰富的BKA儿童的步态中的站立期、摆动期和双支撑期。收集了11名正常儿童、2名经验丰富的BKA儿童和一名初发BKA儿童的运动学数据。结果表明，假肢侧和非假肢侧的步幅之间以及正常儿童和BKA儿童之间存在显著差异。最初，初发BKA儿童的步态与经验丰富的BKA儿童不同。94天后，初发BKA儿童的步态与经验丰富的BKA儿童没有显著差异。得出的结论是，由于假肢的结构和功能与正常情况不同，（a）BKA儿童可能具有不对称的步态模式是合适的，并且（b）康复可能旨在教导近期接受BKA手术的儿童走得更像经验丰富的BKA儿童而不是正常儿童。
