We performed a dual-task experiment to explore the effect of nabiximols on postural control in 22 patients with multiple sclerosis. They were assessed with static posturography and Stroop test in single- and dual-task conditions at treatment start and after 1, 3 and 12 months. At follow-up, we found more impaired postural control in single-task ( F = 3.07, p = 0.044) and dual-task ( F = 4.90, p = 0.005) conditions in patients who continued treatment (continuers, n = 11) compared with those who discontinued (quitters, n = 11)...

The European Society for Clinical Evaluation of Balance Disorders - ESCEBD - Executive Committee meets yearly to identify and address clinical equilibrium problems that are not yet well understood. This particular discussion addressed "discordances" (defined as "lack of agreement") in clinical assessment. Sometimes there is disagreement between a clinical assessment and measured abnormality (ies); sometimes the results within the assessment do not agree. This is sometimes thought of as "malingering" or an attempt to exaggerate what is wrong, but this is not always the case...

OBJECTIVE: Yoga has been shown to improve muscle strength, flexibility, and balance. However, the impact of meditation on dynamic factors such as gait, reactive balance and proprioception has yet to be examined. The purpose of this study was to test if a novel yoga meditation program (YoMed) is as effective as a standard proprioceptive training in improving proprioception, balance and power in older individuals who have fallen. DESIGN: Sixteen older persons were randomly assigned to either the YoMed Group (YM) or Proprioception Training Group (PT)...

Rheumatoid arthritis (RA) and osteoarthritis (OA) are common rheumatic diseases and account for a significant percentage of disability. Posturography is a method that assesses postural stability and quantitatively evaluates postural sways. The objective of this study was to estimate posturographic trajectories applying pattern recognition algorithms. To this end, k-nearest neighbors (k-NN) classifier was used to differentiate between healthy subjects and patients with OA and RA. The following parameters of trajectories were computed: radius of sways, developed area, total length, and two directional components of sways: length of left-right and forward-backward motions...
