  1. aParticipant identification number
  2. bBerg Balance Scale score (0-56 points). v ref : velocity (m/s) calculated from the time to pass 10 meters, measured using a stopwatch. v : velocity during selected steps (m/s) estimated by the extended Kalman filter. v n : velocity v normalized to \(v_{0} = \sqrt {g l_{0}}\). S I Stance symmetry index value for stance times. S I Step symmetry index value for step lengths
