NSEC-AP: normal standing eye-closed anteroposterior sway velocity. NSEC-ML: normal standing eye-closed mediolateral sway velocity. NSEC-VM: normal standing eye-closed velocity moment. NSEO-AP: normal standing eye-open anteroposterior sway velocity. NSEO-ML: normal standing eye-open mediolateral sway velocity. NSEO-VM: normal standing eye-open velocity moment.
