Static posturography in addicted to illicit drugs and alcohol.

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 submitted to a neurotological evaluation including Balance Rehabilitation Unit posturography. RESULTS The stability threshold mean values were significantly lower (p < 0.0001) in users of illicit drugs, with or without alcohol abuse when compared to the control group; the mean values for sway velocity and ellipse area in all evaluated conditions were significantly higher (p <0.05) in the experimental group when compared to the control group, except for the ellipse area in static force surface and opened eyes (p = 0.168). CONCLUSION The balance control of individuals addicted to illicit drugs with or without alcohol abuse could present stability threshold, sway velocity and ellipse area abnormalities in static posturography.
