Fig. 5From: Increased gait variability during robot-assisted walking is accompanied by increased sensorimotor brain activity in healthy peopleCorrelations between relative oxygenated hemoglobin (Hboxy) and gait variability calculated by intraindividual coefficient of variation (CV) during unassisted-walking (UAW) and robot-assisted walking (RAW). a SMA/PMC, supplementary motor area/premotor cortex; b SMC, sensorimotor cortex; the shaded area represents the 95% confidence intervalBack to article page
