Assessment of imbalance in @entity191 ( @entity191 ) usually relies on semi-quantitative ratings. Posturography has been proposed as an objective means to assess imbalance but its relationship to clinical disequilibrium is questionable. In this study static and dynamic posturography was performed in 58 @entity1 with @entity191 and 29 healthy controls. In @entity1 , posturography was related to performance in established clinical tests (pull-test and tandem gait). Posturography did not differentiate between controls and @entity1 with impaired pull-test (IPDimb, n = 28). @entity1 with normal pull-test (IPDstab n = 30) had lower sway than controls in static (P = 0.042) and dynamic posturography (P = 0.001) and also differed from @entity1 with impaired pull-test in static (P = 0.007) and dynamic (P < 0.001) conditions. In @entity1 with side-steps in tandem gait (n = 21), sway in static and dynamic posturography was increased. Sway measures did not differentiate between @entity1 with pull-test scores 1 and 2 or one and >1 side step in tandem-gait, respectively. Results of ANOVA showed that variance of static posturography was related to performance in tandem-gait (P < 0.0001) but not to pull-test performance (P = 0.91). In contrast, dynamic posturography was related to both, tandem-gait (P = 0.012) and pull-test (P = 0.03). Posturographic sway is increased in @entity1 with @entity191 with disturbance of tandem gait and pull-test. Posturographic measures did not distinguish between different degrees of deficits in clinical tests.
