DOI: 10.1109/tnsre.2020.3045268
Abstract: We propose a point-mass biomechanical model to estimate the forces and moments supported by the upper extremity during Lofstrand crutch-assisted gait. This model is based on the Newtonian classical mechanics and the angular momentum theorem.… read more here.
