Static posturography in addicted to illicit drugs and alcohol

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.
