Data are expressed as median (25th percentile, 75th percentile) values. SL=step length; Max height [m]=maximum elevation of the foot during the swing phase; Vmean app.X [m/s]=mean velocity of approach; Vmean obst.X [m/s]=mean velocity during obstacle clearance; WLK=level walking condition; OBST=walking with an obstacle.
