The purpose of this study is to validate of 5 scale-MBI as ADL asessment instrument for stroke patients. The subject was 34 patients following CVA on rehabilitation ther- apy in the rehabilitation hospital, Yonsei medical center. They were assessed with FIM, and 5 scale-MBI in a day. There scores were taken statistics through SAS package, so that we have Pearson's R score. The results is following. 1) FIM and 5 scale-MBI scores averaged 86. 21, 62. 32. 2) On Pearson's R score between FIM and 5 scale MBI was 0. 9345(p(0.001). Therefore there was a very high correlation. 3) On Pearson's R score between motorFIM and MBI was 0.8565(p(0.001), between cog- nitive FIM and MBI was 0.4641(p(0.01). There was significant. 4) On Pearson's R score between same category of FIM and MBI - self care, sphincter control, mobility, locomotion - each others was 0.8960, 0.6974, 0.8585, 0.8540 (p(0.001 ) . In conclusion, 5 scale MBI was found to be useful scale to assess the stroke patients.
