Values presented are Pearson r values. P: total path length; P_ML: path length along the medial-lateral axis; P_AP: path length along the anterior-posterior axis; M_ML: maximal range of sway in the medial-lateral direction; M_AP: maximal range of sway in the anterior-posterior direction; SA: sway angle; V_M: mean sway velocity; V_ML: velocity along the medial-lateral axis; V_AP: velocity along the anterior–posterior axis; A: covered area; D_ML: average center displacement deflection along the medial-lateral axis; D_AP: average center displacement deflection along the anterior-posterior axis
