Fig. 10

Peak joint moments and GRFs. Values are depicted for the elevating, lowering, and delayed lowering strategies on the ipsilateral and contralateral limbs. Each bar depicts the inter-subject mean of the average peak values for each strategy, with standard deviation displayed as error bars. The unperturbed values shown are the inter-subject mean of the 25-stride average prior to perturbation. Moments are reported as Newton-meters/kilogram, and forces are reported as Newtons/kilogram. Asterisks above bars indicate that the value is significantly different from the same metric for unperturbed walking
