AP: Anteroposterior movements; ML: Mediolateral movements

QS: measured during quiet stance; DT: measured during dual task

COM_RMS: RMS amplitude of center of mass (COM) excursions

K_e: mechanical stiffness

B: mechanical damping

Scaled parameters were used in all negative binomial models. Original parameters are given in [12].

P-value based on paired t-test.
