Energy expenditure and biomechanical characteristics of lower limb amputee gait: the influence of prosthetic alignment and different prosthetic components.
In this study , the influence of different prosthetic alignments and components on oxygen consumption and the important biomechanical characteristics of the normal gait pattern of leg amputees was investigated . With 15 transtibial and 12 transfemoral amputees  , the oxygen consumption during walking on a treadmill was analyzed and biomechanical parameters during walking on even ground at a self-selected speed were defined . The amputation of all patients was caused by trauma . Variations of the prosthetic alignment affect the energy consumption of transfemoral amputees more significantly than that of transtibial amputees . Comparison of different prosthetic feet worn by transtibial amputees did not show significant differences regarding metabolic parameters . Compared with conventional hydraulic knee controls , the oxygen consumption of transfemoral amputees provided with an electronically controlled hydraulic knee joint is reduced . All investigated variations can be clearly characterized by the sagittal moments acting on the joints of the prosthetic limb during gait
