Postural control and lifetime alcohol consumption in alcohol-dependent patients

The aim of this study was to examine the relationship between alcohol consumption and postural control in alcohol-dependent patients.

Posturographic measurements were performed in 82 abstinent patients and in 54 healthy controls. The findings in the patients were compared with those in the controls as well as with the daily alcohol consumption, the consumption during 6 months before the admission for alcohol withdrawal therapy and the estimated lifetime alcohol consumption.

Postural control was impaired in alcohol-dependent patients compared to healthy controls. This impairment was related with the lifetime alcohol consumption, but not with the alcohol consumption per day and prior to admission, respectively. Comparing healthy controls, and alcohol-dependent patients with an estimated lifetime alcohol consumption of < 1000 kg and > or = 1000 kg revealed a significant increase in 6 of 8 sway parameters. Furthermore, the lifetime alcohol consumption increased significantly from patients with normal posturographic and clinical findings to those with abnormalities in both examinations.

This study suggests that postural imbalance in abstinent alcohol-dependent patients is related to the lifetime alcohol consumption.
