The aim of this study was to describe the gait of persons with a unilateral transfemoral amputation by means of a questionnaire, gait analysis and measurement of energy expenditure, and to find correlations among the variables studied. The study included 29 transfemoral amputees amputated for other reasons than a chronic vascular disease. The patients were assessed using the following methods: 1) A questionnaire rating the walking distance and walking difficulty in different circumstances. 2) Gait analysis measuring temporal variables and goniometry of hips and knees. 3) Measurement of energy expenditure during sitting and walking. Scores on the questionnaire showed a correlation with socket design, a negative correlation with age and energy expenditure, and a positive correlation with fast speed. The gait of transfemoral amputees was asymmetrical as far as temporal variables were concerned, and for most amputees also for the range of motion of hip and knee. The walking speed of the amputees was lower than that of non-amputees and showed a positive correlation with hip extension-flexion range of motion and a negative correlation with age and stride time. The energy expenditure of the amputees during ambulation was higher than that of non-amputees, and seemed to correlate with residual limb length and the hip abduction-adduction range of motion.
本研究的目的是通过问卷调查、步态分析和能量消耗测量来描述单侧经股骨截肢者的步态，并找出所研究变量之间的相关性。该研究纳入了29名因慢性血管疾病以外的其他原因进行经股骨截肢的患者。采用以下方法对患者进行评估：1）一份对不同情况下步行距离和步行困难程度进行评分的问卷。2）测量时间变量以及髋部和膝部角度的步态分析。3）测量坐着和行走时的能量消耗。问卷得分与接受腔设计相关，与年龄和能量消耗呈负相关，与快速行走呈正相关。就时间变量而言，经股骨截肢者的步态不对称，而且对于大多数截肢者来说，髋部和膝部的活动范围也是不对称的。截肢者的步行速度低于非截肢者，且与髋部屈伸活动范围呈正相关，与年龄和步幅时间呈负相关。截肢者行走时的能量消耗高于非截肢者，且似乎与残肢长度和髋部外展-内收活动范围相关。
