Fig. 5From: 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 speedMean and standard error values for positive work at the ankle (a), knee (b), and hip joint (c), and total positive work across all three joints (d) for all four fore-aft (FA) resistance levels (10% = red, 15% = blue, 20% = green, 25% = black conditions). Note: superscripts represent significant pairwise comparisons with Bonferroni corrections at p < 0.01, 1 = 10%, 2 = 15%, 3 = 20%, and 4 = 25% FA resistance levelsBack to article page
