Fig. 4From: 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 speedEnsemble average profiles of joint powers with standard error (dotted colored lines) for ankle (a), knee (b), and hip (c), respectively, at 10% (red), 15% (blue), 20% (green), and 25% (black) fore-aft (FA) resistance across 0 to 100% of the full gait cycleBack to article page
