Abstract
Objectives: to assess the use of the Voluntary Step Execution Test to identify fallers. Design: cross-sectional retrospective. Setting: two self-care, residential facilities. Participants: a total of 100 healthy old volunteers (mean age = 78.4 ± 5.7). Measurements: the study investigated the use of the Voluntary Step Execution Test to identify fallers under single and dual-task conditions. Berg Balance Test (BBS) and Timed Get Up and Go (TUG) were used to assess balance and gait function. Results: there were no significant differences found between fallers and non-fallers in BBS and TUG (50.5 ± 4.6 versus 52.5 ± 3.4 and 9.4 ± 3.4 versus 7.98 ± 2.3 respectively). There were no statistically significant differences between non-fallers and fallers across all step execution parameters under the single-task condition. However, adding cognitive load to the Voluntary Step Execution Test revealed statistically significant increases in duration of the preparatory phase, swing time and the time to foot-contact ( P = 0.035; P = 0.033 and P = 0.037, respectively). Based on the coefficients of the logistic regression model participants with dual-task step execution times of ≥1,100 ms had five times the risk of falling than participants with execution times of Conclusions: the study provides evidence that a simple, safe measure ofstep executon under dual-task conditions can identify elderly individuals at risk for falls.
