Table 1 Comparison of vertical ground reaction force variables (GRF; mean ± SD) during the stance phase of unassisted walking (UAW) and robot-assisted walking (RAW), SD = standard deviation

From: Increased gait variability during robot-assisted walking is accompanied by increased sensorimotor brain activity in healthy people
