Summary:The Kerlan-Jobe Orthopedic Clinic shoulder and elbow score (KJOC score) was developed for assessing performance and function in overhead athletes with shoulder and elbow injury and recently adapted as the standard score for overhead athletes in Major League Baseball. However, the Korean version of the KJOC score was not developed in the literature. The aim of the current study was to adapt the English version of the KJOC score to develop a Korean version (K-KJOC) and to evaluate its validity and reliability. A total of 52 professional baseball players in the Korean Baseball League completed the K-KJOC at two-week intervals during the off-season. The QuickDASH (11-point Disabilities of the Arm, Shoulder and Hand) score was also performed to evaluate the construct validity of the K-KJOC score. The internal consistency of reliability and test–retest reliability were assessed as well. The K-KJOC score was correlated with the Quick DASH – disability/symptom (−0.309, ~−0.268, p
