^aParticipant identification number
^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
