Comparison of (a) step length and (b) cadence between pre- and post-training gait for 73 older adults. The step length was calculated from the farthest distance of the left-to-right heel (i.e., between their most posterior positions) during stance phase and normalized to the body height (bh). The cadence was determined as the reciprocal of the duration from TD to the following TD at the contralateral limb and expressed over 1 minute.
