Quantifying Nonlinear Ankle Quasi-Stiffness During Level and Sloped Walking.

Natural ankle quasi-stiffness describes the joint's resistance to motion during loading in gait, which is informative for the design of biomimetic devices (eg, prostheses, orthoses, and exoskeletons). Ankle quasi-stiffness is typically quantified as the slope of the moment-angle curve using a linear approximation. Yet,...
