Abstract. [Purpose] The purpose of this study was to clarify the criterion validity, construct validity, and feasibility of the Functional Assessment for Control of Trunk (FACT). [Participants and Methods] This study was a multicenter, cross-sectional study of patients with subacute stroke at three Japanese rehabilitation hospitals. To clarify feasibility, we examined the differences in the measurement time between FACT and the Trunk Impairment Scale (TIS). For the criterion validity of FACT, correlations between FACT, TIS, and the trunk items of the Stroke Impairment Assessment Set (SIAS) were examined using Spearman's rank correlation coefficient. For the construct validity of FACT, we examined the correlations with the other assessments. [Results] Seventy-three patients participated in this study. The measurement time was significantly shorter for FACT (212.6 +- 79.2 s) than TIS (372.4 +- 199.6 s). For criterion validity, FACT correlated significantly with TIS (r=0.896) and two SIAS trunk items (r=0.453, 0.594). For construct validity, significant correlations were found for FACT and other tests (r=0.249-0.797). Areas under the curve for FACT and TIS were 0.809 and 0.812, respectively, and the cutoff values for walking independence were 9 and 13 points, respectively. [Conclusion] For inpatients with stroke, FACT offered feasibility, criterion validity, and construct validity.
