Energy expenditure of transfemoral amputees during floor and treadmill walking with different speeds.

Background: Walking energy expenditure, calculated as the percent utilization of the maximal aerobic capacity, is little investigated in transfemoral amputees.

Objectives: Compare the energy expenditure of healthy participants (control participants) and transfemoral amputees walking with their respective preferred walking speeds on the treadmill (TPWS) and floor (FPWS).

Study Design: Randomized cross-over study.
