Objective: The purpose of this study was to clarify the cutoff values of the modified five-repetition Sit-to-Stand and the One-Leg Stand tests, which discriminate life-space mobility in community-dwelling older adults certified as needing support or care.
Methods: Data obtained from 66 adults (age: 80.9±7.6 years, 39 women) who were using either day-care rehabilitation or home-visit nursing stations were analyzed cross-sectionally. Participants were classified into two groups according to the degree of life-space mobility as determined by Life Space Assessment. Cutoff values and discriminant accuracy of both tests were calculated using the Youden Index and area under the curve (AUC) based on the receiver operating characteristic curve.
Results: The respective AUCs and cutoff values were 0.905 (sensitivity: 0.889, specificity: 0.754) and 12.82 sec for the modified five-repetition Sit-to-Stand test and 0.860 (sensitivity: 0.778, specificity: 0.842) and 7.25 sec for the One-Leg Stand test.
Conclusion: The results suggest that lower-limb muscle strength and balance ability are important indicators for life-space mobility in community-dwelling older adults needing support or care. The findings of this study contribute to decision making in goal setting and intervention planning in physical therapy aimed at improving social participation in older adults.
