UNLABELLED The use of illicit drugs and alcohol can affect body balance. AIM To evaluate balance control with static posturography in individuals addicted to illicit drugs, with or without alcohol abuse. STUDY DESIGN Case-control, prospective. METHODS 47 users of illicit drugs, with or without alcohol abuse, and a homogeneous control group consisting of 47 healthy individuals were submitt...

Sensory-motor control of upright human posture may be organized in a top-down fashion such that certain head-trunk coordination strategies are employed to optimize visual and/or vestibular sensory inputs. Previous quantitative models of the biomechanics of human posture control have examined the simple case of ankle sway strategy, in which an inverted pendulum model is used, and the somewhat mo...

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...

Objective: To develop and assess the efficacy of a multimodal balance-enhancing exercise program (BEEP) designed to be regularly self-administered by community-dwelling elderly. The program aims to promote sensory reweighting, facilitate motor control, improve gaze stabilization, and stimulate continuous improvement by being constantly challenging. Method: Forty participants aged 60 to 80 years...
