Presented are results for sensitivity to change for effects of early rehabilitation during hospital stay
Abbreviations: SD Standard deviation, SRM Standardized response mean, 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; Adjusted SRMs are classified as < 0.2 = trivial, ≥0.2 < 0.5 = small, ≥0.5 < 0.8 = moderate, ≥0.8 = large
