PRE/POST differences in postural stability tests. PSTC – postural stability tests without additional task; PSTE – postural stability test with additional task (counting); PSTLOS – limits of stability test, Vcop – velocity of center of pressure, RMSVX – medio-lateral root mean square of velocity; RMSVY – anterior-posterior root mean square of velocity; Area95 – area 95 percentile, RangeX – medio-lateral range of sway, RangeY – anterior-posterior range of sway, JP – juggling period, NJP – non juggling period
