BACKGROUND This study used a dual task design to examine the effect of sensory context on postural stability during the concurrent performance of an attentionally demanding cognitive task in young and older adults with and without a history of imbalance and falls. METHODS A choice reaction time auditory task was used to produce changes in attention during quiet stance in six different sensory...

An acute unilateral vestibular lesion leads to a vestibular tone imbalance with nystagmus, head roll tilt and postural imbalance. These deficits gradually decrease over days to weeks due to central vestibular compensation (VC). This study investigated the effects of i.v. N-acetyl-DL-leucine, N-acetyl-L-leucine and N-acetyl-D-leucine on VC using behavioural testing and serial [18F]-Fluoro-desoxy...

INTRODUCTION Postural instability is one of the most disabling features of Parkinson's disease. OBJECTIVE To evaluate postural balance in Parkinson's disease. METHODS Thirty patients with Parkinson's disease were compared with controls using Tetrax™ interactive balance system posturography. RESULTS For different positions, patients with Parkinson's disease showed a significantly higher we...

The aim of this study was to assess the prevalence of ataxia of stance in different types of alcohol-dependent patients. Posturographic measurements were performed in 82 abstinent alcohol-dependent patients and 54 healthy controls in order to analyse postural control. According to Lesch and co-workers, alcohol dependence was classified as total abstinence (Type I), drinking without loss of cont...

Although motor output of the postural function clearly influences postural performance in young and older subjects, no relationship has been formally established between them. However, the relationship between lower-extremity muscle strength/power and postural performance is often pointed out, especially in older subjects. In fact, the influence of motor output may vary according to the postura...

Balance training and postural response assessment have been for decades two separate tasks in the rehabilitation medicine. The former concerns physiotherapy and the latter diagnostics. The virtual-reality technology does not only enhance the possibilities of balance training, but in combination with a haptic floor enables the subjects to gain a postural imbalance experience. The differences in ...

PURPOSE Two potential mechanisms leading to postural and osseous shoulder deformity after brachial plexus birth palsy are muscle imbalance between functioning internal rotators and paralyzed external rotators and impaired longitudinal growth of paralyzed muscles. Our goal was to evaluate the combined and isolated effects of these 2 mechanisms on transverse plane shoulder forces using a computat...
