Background: JOA score (JOA) is health professional side evaluation, but Shoulder 36 (Ver1.3) (Sh36) is patient basis evaluation. Although the reactivity of Sh36 and reliability were estimated by Maruyama, there were few reports of the relation between each item of JOA and Sh36. Methods: 101 shoulders which underwent arthroscopic surgery (Rotator cuff tear 67, shoulder instability 28, contracture 6) were investigated. Preoperatively, the rank correlation of Spearman examined the correlativity between pain, function, ROM and ADL of Sh36 to JOA. Moreover, the same examination was performed for each disease and disease singularity was also examined. Results: In all the cases, correlation of JOA and Sh36 was found in pain (P ‹ 0.01), functions (P ‹ 0.01), ROM( P ‹ 0.01) and ADL (P ‹ 0.01). On the other hand, in rotator cuff tear only correlation of JOA and Sh36 with function (P ‹ 0.01) and ROM (P ‹ 0.05) were found and in shoulder instability a correlation with function (P ‹ 0.05) was found. At shoulder contracture, correlation of JOA and Sh36 was found in no items. Conclusion: Correlation was found between each item of pain, a function, ROM, and ADL of JOA and Sh36 in all cases. However, there was no correlation in pain at rotator cuff tear and contracture, and there was in ROM at shoulder instability. It seems that more detailed shoulder joint evaluation of function can be performed by performing evaluation of JOA and Sh36 on both sides.
