Abstract
Introduction
The Timed Up and Go (TUG) is a test widely used to assess the risk of falls in older adults. Although it is a complex task, only the total TUG time has been used for evaluation. The widespread use of smartphones has provided the development of applications for monitoring diagnostic procedures.
Objective
To analyze the ability to predict future falls in older adults.
Methods
A cohort study (1 year) of 42 participants using the sTUG Doctor. Fall events during 1-year follow-up were monitored by telephone. The number of days between assessment and first fall or last contact was calculated for survival analysis, assessed by unadjusted and adjusted Cox proportional hazards regression models. Tests with p <5 % were considered statistically significant and between 5% and 10% were indicative of significance (Epi-Info™ 7.2).
Results
Falls were observed in 22 (52.38%) participants (fallers). The results indicated that cognitive impairment, depressive symptoms, women, and participants with fear of falling (FES-I) were more likely to fall. Fallers performed worse on all sTUG Doctor phases. Hazard ratios for predicting falls were significant for total TUG time (1.35; p = 0.029) and total number of steps (1.52; p = 0.057). Total TUG time remained significant when adjusted for sex, age group, FES-I, and depression level.
Conclusion
The sTUG Doctor was an important tool to predict falls in community-dwelling older adults.
