Individual Margins of Instantaneous Dynamic Stability: Verification in Elderly with Mobility and Balance Tests

Abstract

A verification of individual margins of instantaneous dynamic stability in elderly volunteers is presented. The modified condition and margins of instantaneous dynamic stability permitting the estimation in elderly are proposed. By utilizing in experimental protocols of conventional tests of mobility, i.e. Up-and-Go activity, and balance, i.e. mini-BEST, the periodic stability indices were estimated in elderly without introducing fall prone incidence. The margins of instantaneous dynamic stability or the risk of falls of each elderly volunteer was compared to the healthy young group. The accuracy of fall risk estimation by using the current method tested in fall incidences of young and healthy volunteers was presented. © 2020, Springer Nature Switzerland AG.
