Comparison of the Responsiveness of the Long-Form and Simplified XXXX Rehabilitation Assessment of Movement: Group- and Individual-Level Analysis.

@entity1 @entity64
BACKGROUND: The group-level responsiveness of the original, 30-item @entity64 Rehabilitation Assessment of Movement measure (STREAM-30) is similar to that of the simplified STREAM (STREAM-15), even though the STREAM-30 has twice as many items as those of the STREAM-15. OBJECTIVE: The purpose of this study was to compare the responsiveness of the STREAM-30 and STREAM-15 at both group and individual levels in @entity1 with @entity64 . For the latter level, the Rasch-calibrated 27-item STREAM (STREAM-27) was used because the individual-level indexes of the STREAM-30 could not be estimated. DESIGN: A repeated-measurements design was used. In total, 195 @entity1 were assessed with the STREAM-30 at both admission and discharge. METHODS: The Rasch scores of the STREAM-27 and STREAM-15 were estimated from the @entity1 ' responses on the STREAM-30. We calculated the paired t-test value, effect size, and standardized response mean as the indexes of group-level responsiveness. The significance of change for each @entity1 was estimated as the individual-level responsiveness index, and the paired t test and test of marginal homogeneity were used for individual-level comparisons between the STREAM-27 and STREAM-15. RESULTS: At the group level, the STREAM-30, STREAM-27, and STREAM-15 showed sufficient and comparable responsiveness. At the individual level, the STREAM-27 detected significantly more @entity1 with significant improvement and fewer @entity1 with no change or deterioration compared with the STREAM-15. LIMITATIONS: Few @entity1 with subacute @entity64 showed deterioration at discharge, so the abilities of the 2 measures to detect deterioration remain inconclusive. CONCLUSIONS: The STREAM-27 detected more @entity1 with significant recovery compared with the STREAM-15, although the group-level responsiveness of the 2 measures was the same. The STREAM-27 is recommended as an outcome measure to demonstrate the treatment effects of movement and mobility for @entity1 with @entity64 .
