Reproducibility of Trunk Control Assessment and the Clinical Utility of the Distinguishing Barthel Index in Chronic Stroke Patients

PURPOSE: This study examined the test-retest reliability and clinical utility of the Modified Trunk Impairment Scale (mTIS), Trunk Control Test (TCT), and Postural Assessment Scale for Stroke -Trunk Control (PASS-TC) in patients with chronic stroke.METHODS: Thirty-eight stroke patients were reassessed using the mTIS, TCT, and PASS-TC with a seven-day interval between assessments.The test-retest reliability was evaluated using the intraclass correlation coefficient (ICC 2,1 ), the standard error of measurement (SEM), the minimal detectable change (MDC), and MDC%, as well as Bland-
