Fig. 2 — Kinematic parameter recordings of gait initiation. Kinematic parameters of gait initiation in an individual patient. From top to bottom, curves represent the smoothed mean of ten trials and show the vertical centre of mass velocity (CoM-Vz), mediolateral (CoP x) and anteroposterior (CoP y) displacements and anteroposterior centre of foot pressure (CoP) velocity (CoP-Vy). APAs: anticipatory postural adjustments, DS: double-stance, CoP: centre of foot pressure, CoM: centre of mass, FC: foot contact of the swing leg, FO1: foot-off of the swing leg, FO2: foot-off of the stance leg, L: step length, t0: time of the first biomechanical event, V1: negative peak of the CoM vertical velocity, V2: CoM vertical velocity at the time of foot contact, W: step width
