Age characteristics of postural control components in women 55-64 years old

The purpose of the study was to reveal age characteristics of the components of postural control in women 55-64 years old. Computer dynamic stabilometrical complex «Smart Equitest Balance Manager» was used for the comprehensive evaluation of the equilibrium function in elderly women. The following tests were used: Sensory Organization Test (SOT), Motor Control Test (MCT), Rhythmic Weight Shift (RWS). On the basis of the analysis of postural control parameters and according to the SOT data, we have found a quality decrease of the equilibrium function in the functional tests 1-4, as well as reduction in the degree of involvement of the somatosensory information in the balance control in women after 59 years. In addition, comparative analysis also revealed a weakening of postural strategy in all six functional tests SOT. However, no age-related changes have been found in the quality of the equilibrium function (functional tests 5 and 6), being the result of SOT assessment, as well as the degree of involvement of visual and vestibular information in the balance control. The analysis of the MCT test has shown deceleration of coordinated motor reactions. RWS test analysis has shown that women from 59 years had a quality deterioration of gravity control center while moving in the frontal and sagittal directions, as well as speed reduction of the gravity center movements in the sagittal direction.
