Abstract: The research on the effects of experienced emergency and extreme situations on the health of an aging person continues to be one of the topical issues of gerontology and geriatrics. The purpose of this work was to identify the features of postural response and oscillatory movements of the center of gravity (CoG) in elderly women who survived the fire. Materials and methods. 94 women aged 60–69 years were examined (mean age (M±SD) — 63.2±2.3 years). The study group (SG) included 47 women who reported that they had experienced an extreme fire situation 4 to 18 weeks ago. The comparison group (CG) also included 47 women who over the past two years have not experienced any extreme situations (fire hazard, criminal, road traffic), as well as the death of close relatives. To assess the features of the components of the postural balance (CPB), a computer dynamic posturographic complex “Smart Equitest Balance Manager”, manufactured in the USA, was used. The following tests were performed: Motor Control Test (MCT) and Rhythmic Weight Shift (RWS). The results of the study. When analyzing MCT, it was found that women in the SG have the higher markers of the resulting assessment of the delay in the entire test compared to the CG (p=0.040), which indicates a slowdown in the rate of coordinated motor reactions in female fire victims. When comparing the results of the RWS test, it was found that the quality indicators for controlling CoG in the left-to-right direction in the SG were higher than in the CG (p=0.002), which indicates a decrease in the quality of control of the CoG movement in the frontal plane in women who survived the fire. Conclusion. Stressful situations associated with the experienced by elderly women extreme or emergency situations are accompanied by a deterioration in their CPB. The obtained results substantiate the possibility of using computer posturography through biofeedback not only for physical but also psychological rehabilitation.
