Transfemoral Amputations: Is There an Effect of Residual Limb Length and Orientation on Energy Expenditure?

摘要

BackgroundEnergy cost of ambulation has been evaluated using a variety of measures. With aberrant motions resulting from compensatory strategies, persons with transfemoral amputations generally exhibit a larger center of mass excursion and an increased energy cost. However, few studies have analyzed the effect of residual femur length and orientation or energy cost of ambulation.
