Abstract
Objective To study the validity,reliability and sensitivity of the simplified Chinese version of modified Barthel index (MBI) in evaluation of activities of daily living(ADL) of Chinese stroke patients. Methods Forty Chinese stroke patients (26 males and 14 females,aged 59.65±11.68 years) participated in the study.The duration of the disease averaged 21.20±19.44 days.All the patients were evaluated for three times with MBI.Barthel Index (BI) and the motor component of Functional Independence Measure (M-FIM)independently by twophysiatrists.Spearman correlation coefficients between MBI and Barthel index (BI),between MBI and M-FIM were used to test the validity of MBI.Intraclass correlation coefficients (ICC) were used to test both interrater and intra rater reliability of MBI.Sensitivity of MBl was analyzed with the Wilcoxon signed rank test and paired t-test.Results MBI was highly correlated with BI in each item and total score(r=0.816~1.000,P<0.01),and with M-FIM in total score(r=0.935~0.981,P<0.01).There were high reliability with MBI in the results collected by same assessor and different assessors(ICC=0.866~0.997).Furthermore,MBI was more sensitive than BI in majorities of its items and its total scores as well.Conclusions MBI has good validity and reliability as well as sensitivity in assessment of ADL of Chinese stroke patients.
