Background and objective: This study aimed to explore optimal cut-off scores of the three-time stand and walk test (TTSW) in elderly Thais.

Methods: Based on the physiological changes, participants were divided into 3 age groups; 60-69 years, 70-79 years, and 80 years or more. The total of 186 participants (62 participants per age group) were interviewed and subjective examined for their demographics, health status and their history of falls within the past 6 months. All participants were divided into 2 groups: falls and non-falls. Thereafter, participants were performed the TTSW for 3 trials, and the mean values obtained from 3 trials were used for statistical analyses.

Results: Most of study participants were female. There was no significant difference in body mass index between falls and non-falls. Participants in the fall group had a significantly higher mean TTSW scores than those in the non-fall group (p<0.001). The mean cut-off scores of TTSW in each age group were 14.00, 14.13, and 15.30 seconds, respectively, with high sensitivity, specificity, predictive accuracy and area under receiver operating characteristic (ROC) curve of the TTSW test in each group.

Conclusions: This study concluded that the cut-off scores of the TTSW in each age group could be used as a criterion value for assessing the risk of falling in community-dwelling elderly participants.
