a Experimental setup (left). Example participant walking with asymmetric step lengths (center) and resulting visual display showing step length feedback bilaterally (right). b Step lengths (mean ± SE curves) for the limbs that took longer (blue) and shorter (red) steps at baseline during preferred walking (left) and symmetric stepping (right). The data shown have been truncated to number of strides for the participant that took the fewest strides for the same duration of the trial. c Step length asymmetry decreases significantly during symmetric stepping (green) as compared to preferred walking (purple). d The net metabolic cost of transport is similar between preferred walking and symmetric stepping
