From: Fore-aft resistance applied at the center of mass using a novel robotic interface proportionately increases propulsive force generation in healthy nonimpaired individuals walking at a constant speed

Fig. 3

Dominant limb ensemble average (with standard error) fore-aft GRF profiles (a); and ensemble average (with standard error) vertical GRF profiles (b) across all FA resistance conditions at 1.0 m/s target velocity. Propulsion phase (shaded area in A) highlights the second half of the stance phase used for propulsion calculations. Note red = 10%, blue =15%, green = 20% and black =25% B.w. fore-aft resistance levels
