Evaluation of postural balance in patients with obstructive sleep apnoea syndrome.

Abstract:

INTRODUCTION:Patients with obstructive sleep apnoea syndrome (OSAS) can be more prone to accidents due to excessive daytime sleepiness which can lead to attention deficits and thereby cause balance problems. One of the tests evaluating postural balance is static posturography (SPG). In this study, we aimed to evaluate postural balance with SPG in OSAS patients. METHODS:Patients who were referred to a sleep disorders outpatient clinic of a tertiary health care centre with snoring, daytime sleepiness or witnessed apnoea were enrolled consecutively in this cross-sectional study. They were grouped as the OSAS group and the control group according to the apnoea-hypopnoea index. Posturographic analyses were carried out in all subjects on a SPG platform under five different conditions: eyes open (EO), eyes closed (EC), head rotated to left (HL), head rotated to right (HR), and tandem Romberg. RESULTS:A total of 95 patients and 23 controls were included in the study. In EO conditions, there was no difference between the OSAS group and the control group in any of the posturographic parameters. In EC conditions, change in lateral sway was significantly higher in the OSAS group which also correlated negatively with SaO2(min). HR conditions caused an i ncrease in anterior-posterior (A-P) sway velocity, and HL conditions led to an increase in change in lateral and A-P sways, sway area, and sway area velocity in the OSAS group. CONCLUSIONS:Our findings suggest that postural balance in OSAS patients is impaired even in the very first hours of the day, and that the severity of the disease has an impact on postural balance.
