Abstract
Background: The Three Times Stand and Walk test (TTSW) is functional test used to predict the risk of falling in Thai community-dwellings elderly. However, there is a lack of supporting information, such as the optimal cut-off scores to be used for prediction, and therefore the validity of the test itself.
Objectives: The objectives of this study were to develop and evaluate the predictive validity to optimize the cut-off scores of TTSW. Additionally, the predictive ability of TTSW was compared with standard tools.
Methods: Seventy community-dwelling subjects aged ≥ 60 years, 35 subjects having experienced at least one fall in the past 6 months and 35 non-faller subjects. All subjects were evaluated the basic demographics and performed the functional test including TTSW, Timed Up and Go test (TUGT), and Five Times Sit-to-Stand test (FTSST). Results: A prominent result of this study showed that TTSW possessed ≥ 12 seconds for cut-off scores. Additionally, TTSW demonstrated the highest level of sensitivity, specificity, and area under ROC curve (AUC) (sensitivity = 80.00%, specificity = 91.43% and AUC = 0.87; 95%CI; 0.79-0.98). The other two tests, TUGT and FTSST, showed lower sensitivity (68.57% and 65.71%), specificity (80% and 77.14%), and area under ROC curve (= 0.82; 95%CI = 0.72-0.92 and 0.77; 95%CI =0.66-0.88).
Conclusions: The TTSW can be used as a fall prediction tool. Overall, the results of this study demonstrated the Thai community-dwelling elderly required duration for complete TTSW was ≥ 12 seconds, suggesting risk of fall.
