The joint moment is effective for quantitative physical load evaluation. We normally solve the joint moment by inverse dynamics with ground reaction force. However, a force plate which acquires ground reaction force data is too expensive for daily use. In this paper, we present a simple model for joint moment calculation based on the slope deflection method which does not require ground reaction force. We focused on a knee joint for basic study as it can be assumed to be a hinge joint. We estimated the knee joint moment during steady state walking and validated with three-dimensional motion analysis and force plate.
