Abstract:

Abstract: This paper addresses whether whole-body force feedback on treadmill-style locomotion interfaces can simulate the gravity forces experienced when walking on smooth inclines. By applying horizontal force feedback possible with the active mechanical tether of the Sarcos Treadport, it is shown that the biomechanics of walking are similar under conditions of real slope walking versus tether force walking. These biomechanical results complement previous psychophysical studies which yielded the same result, to conclude denitively that whole-body force feedback can realistically substitute for treadmill tilt. 1.
