Ability of the Brief-Balance Evaluation Systems Test to evaluate balance deficits in community-dwelling older adults: a cross-sectional study

Abstract

ABSTRACT Background A method for assessing balance that differentiates between balance deficit can help guide effective interventions for preventing falls in older adults. Objective This study aimed to clarify the relationship between balance control systems and falls, and to examine the ability of the Brief-Balance Evaluation Systems Test (BESTest) to evaluate balance deficits in older adults. Methods Overall, 109 community-dwelling older adults participated in this study. The history of falls in the last year was investigated. Balance deficits were assessed using the Brief-BESTest, the functional reach test, the Timed up and Go Test, and the one leg balance test. We analyzed the difference between the fallers and non-fallers across two different age groups. Results Among younger-older group participants (age < 75 years), there were no significant differences between fallers and non-fallers across all variables. Among older-older group participants (age ≥ 75 years), there were significant differences in the Brief-BESTest total (p= .011; fallers, 13.5 versus non-fallers, 17.0) and section IV scores (postural responses of the Brief-BESTest; p= .026, 2.0 versus 5.0). There was no significant difference in other balance measurements. Conclusions The postural responses assessed by the Brief-BESTest may serve important functions and may be associated with falls in older adults.
