The community-mobility statuses of 203 communitydwelling elders were classified as able, decreased, or disabled based on their self-reported ability to walk several blocks and climb stairs. They also performed the functional reach, timed 50-ft walk, timed 5-step, timed floor transfer, and 5-min-walk endurance tests. We found in all tests that the "able" outperformed the "decreased" and that the "decreased" outperformed the "disabled," except on the floor-transfer task. The optimum cutoff values of the 5 performance tests were also reported. The 5-min walk and timed 5-step test could best separate the "able" from the "decreased," whereas the 50-ft-walktest could best differentiate the "decreased" from the "disabled. " The results suggest that community-mobility function of older adults can be captured by performance tests and that the cutoff values of the 5-min-walk, 5-step, and 50-ft-walk tests can be used in guiding intervention or prevention programs.14enjournal article
