Simulation result with device. Motion of stance leg and swing leg – (i) with assistive device and optimal parameters of the torsional spring; (ii) With assistive device and optimal parameters of the torsional spring but with 50% change in leg mass. Stance leg – red dotted line. Swing leg – blue solid line. Initial position of swing leg – thick blue line with diamond markers. Final position of swing leg – brown line with star makers.
