In-lab usual-walking and in-lab dual-task walking compared to daily-living walking typical, best and worst gait values of: a) step length; b) gait speed; c) step regularity; d) stride regularity and e) step time. The light blue bars reflect the in-lab values of usual-walking (UW) and dual-task walking (DTW). The results shown here are based on 30-s walking bouts
