Estimations of metabolic cost of gait using inverse methods and a weight-based adjustment

Metabolic cost of transport (MCoT) of gait was estimated from marker data and ground reaction forces (GRFs). Sagittal plane joint angles and joint moments were determined using inverse kinematics and dynamics, respectively, and muscle states were determined by dynamic optimization. Metabolic cost of the simulations was calculated from two metabolic energy expenditure models, and adjusted based on the subject's weight.
