We investigated early signs of @entity191 in mediolateral postural control. Thirty-six @entity1 (18 Hoehn _ Yahr stage 2 @entity1 in the off-drug condition and 18 healthy controls) were studied in a stationary gaze condition and when performing 80   lateral gaze shifts at 0.125 and 0.25 Hz. Body sway, coordination and postural control mechanisms were analyzed. All @entity1 performed the visual tasks adequately. The @entity1 were not unstable in the stationary gaze condition. In both groups, mediolateral ankle- and hip-based postural control mechanisms were significantly more active under gaze shift conditions than under the stationary gaze condition. As expected, the @entity1 exhibited significantly greater angular movements of the lower back and significantly lower angular movements of the head (relative to controls) when performing gaze shifts. When considering linear displacements (rather than angular movements), the @entity1 exhibited significantly greater displacements of the lower back and lower, slower displacements of the head than controls under gaze shift conditions. Relative to controls, the @entity1 performed "en block" body movements. Overall, our results show that the @entity1 ' ankle- and hip-based mediolateral postural control mechanisms did not adapt to the difficulty of the visual task being performed.
