The oxygen consumption and the total quantity of oxygen consummed were measured continuously during a hard test of inclined walking, in four young traumatic below-knee amputees. The test consisted of an 18 minute walk with twice a 12 to 15% gradient according to the performance level of the subject. A Sach foot was compared to a Copy III prothesis. The quantity of oxygen consummed was systematically weaker with the Copy III foot. The differences were more clear as the oxygen consumption increased. These results suggest the necessity to use tests of relatively intense walking to evaluate the benefit of a new type of prothesis, the interest of energy-storing prosthetic feet in young subjects having regular physical activities.
