Comparison of postural control on solid and mobile supports

The aim of the study was to investigate the features of postural control during static one-legged stance on a solid stable platform (Plt) and on a movable in the sagittal plane support (a see-saw device, SeS). The postural stability in healthy young girls (n = 33) was assessed using the velocity of oscillations of the common center of pressure (V-COP, stabilography), angular velocities in hip (V-HJ), knee (V-KJ), ankle (V-AJ) joints using goniometric sensors. It was established that in the stance on SeS, V-COP, as well as V-HJ, V-KJ, V-AJ joints were significantly greater than on the solid support (all p
