  1. Presented are results of test-re test reliability for the total group and sub-scores according to cognitive status
  2. Abbreviations: CI Confidence interval, LSA-IS Life-Space Assessment for institutionalized settings, LSA-IS-T Total life-space mobility, LSA-IS-M Maximum life-space, LSA-IS-E Maximum life-space with equipment, LSA-IS-I Maximum independent life-space; ICCs were interpreted as poor (< 0.4), fair to good (≥ 0.4 ≤ 0.75), and excellent (> 0.75)
