Methods : First, fifty stroke inpatients from department of rehabilitation were tested at admission and discharge. Spearman correlation coefficients (ρ) were used to evaluate validity between STREAM and relative scales (including Fugl-Meyer motor scale, Postural Assessment Scale for Stroke Patients, Barthel Index). Standardized response mean (SRM) was used to examine the change in score of the STREAM. Second, fifty stroke outpatients were tested twice, seven days apart. Inter-class correlation coefficient (ICC) was used to examine the level of agreement between test and retest. Absolute reliability indices, including the standard error of measurement (SEM) and the smallest real differences (SRD), were used to determine the extent. Results: There are neither ceiling effect nor floor effect in the distribution of STREAM total scores, indicating that there is no acceptability at admission and at discharge. STREAM showed the high concurrentvalidity with FM-motor ( ρ ≧ .88), the high convergent validity with PASS (ρ≧ .81), and the moderate convergent validity with BI (ρ≧ .76) at admission and at discharge. The scores of the STREAM at admission showed the high predictive validity with the scores of the FMA, PASS and BI at discharge(ρ≧ .83). Responsiveness of the STREAM from admission to discharge washigh (SRM ≧ .78). ICC was 0.989(95% CI=0.981~0.994), indicating good test-retest agreement. The SEM of the STREAM was 2.0, representing the smallest change threshold that indicates a real improvement for a group of individuals. The SRD of the STREAM was 5.5, exhibiting the smallest change threshold that indicates a real improvement for a single individual. Conclusion : The STREAM has high levels of acceptability, validity, and responsiveness and high agreement between the test-retest measurements with acceptable measurement errors. This suitable and brief assessment tool can be used for clinicians and researchers to assess the motor function of the stroke patients.
