Assessment of functional independence and residual disability is very important for measuring treatment outcome after stroke. The modified Rankin Scale (mRS) the Barthel Index (MBI) are commonly used scales to measure or dependence in activities daily living (ADL) stroke survivors. Lack consensus regarding MBI score categories has caused confusion interpreting outcomes. purpose this study was identify optimal corresponding scale grades categorization MBI. Korean versions (K-MBI) mRS were collected from 5,759 patients at 3 months onset sensitivity specificity calculated K-MBI cutoffs each grade obtain optimally scores grades. We also plotted receiver operating characteristic (ROC) curves determined area under curve (AUC). cutoff points with highest sum 100 (sensitivity 0.940; 0.612), 98 0.904; 0.838), 94 0.885; 0.937), 78 0.946; specificity, 0.973), 55 937; 0.986) 0, 1, 2, 3, 4, respectively. From result, range can be obtained. For 100, indicating no associated range. 5, ranges 99 98, 97 94, 93 78, 77 55, 54, respectively.The AUC ROC 0.791 0.919 0.970 0.0 0.991 4. representing variable; 2 had narrow ranges, while 5 exhibited broad ranges. seemed sensitively differentiate mild survivors, whereas provided more specific information status survivors moderate severe impairment.
