Abstract

The purpose of this study was to determine the underlying factor structure of commonly used clinical balance measurements. Subjects comprised 79 community-dwelling elderly people (mean age: 79 ± 5.9 years) who were receiving a day-care rehabilitation program. Six clinical balance tests were administered to the subjects on a single occasion. The tests comprised two measures of sway using postulography, the Manual Perturbation Test, the Functional Reach Test, the Functional Balance Scale and the Performance-Orientated Mobility Assessment. Exploratory factor analysis revealed four underlying balance factors; standing balance, ability to withstand perturbations, leaning balance with a stationary base of support and dynamic balance with movement of the base of support. Structural equation modeling confirmed that these four factors comprised the substructure of the balance assessments. These findings are helpful for identifying the tests required for comprehensive assessment of balance in elderly people.
