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.
