Comparison of KJOC Scores in College Athletes With and Without Arm Trouble Across Overhead Sports.

Context: Shoulder and elbow problems are common among athletes in overhead sports, making 7 it essential to understand the characteristics of active athletes with arm trouble to improve and prevent upper extremity disorders. The Kerlan-Jobe Orthopaedic Clinic (KJOC) Score is widely used to evaluate upper extremity functionality in this population. Objective: (1) To compare the KJOC score between athletes with and without arm trouble in various overhead sports; and (2) to clarify the relationship between subjective competitive levels and functional characteristics using correlation analysis of the KJOC score questions.

Translation and Cross-cultural Adaptation of the Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow Score Into Japanese and Comparison of Visual Analog Scale and 10-Point Scale Formats.

Background: The Kerlan-Jobe Orthopaedic Clinic shoulder and elbow score (KJOC) is sensitive enough to detect subtle changes in the functional level of the shoulder or elbow in overhead athletes. However, a Japanese version of the KJOC is not yet available. Moreover, the original KJOC uses a visual analog scale (VAS) assessment format that requires a print version so that users can add a check mark along a horizontal line.
