Brief summary
Various clinical scales are available to investigate shoulder diseases. Some of them, culturally adapted to the Turkish population. However, none of them are specific for osteoarthritis of the shoulder. Thus, this study aimed to translate the WOOS index into Turkish and investigate its psychometric properties in the Turkish population.
Detailed description
Purpose; The aim of this study is to adapt the Western Ontario Osteoarthritis of the Shoulder Index (WOOS) specific to shoulder osteoarthritis, to Turkish and evaluate its validity and reliability. Methods; WOOS index was translated and culturally adapted to Turkish, systematically. It was applied to 68 patients with osteoarthritis of the shoulder treated conservatively. The reliability of the scale was checked through internal consistency and test-retest methods. Internal consistency was analyzed with Cronbach's alpha value. Test-retest reliability was assessed using an intraclass correlation coefficient with 25 patients. The Western Ontario Rotator Cuff (WORC), The Shoulder Pain and Disability Index (SPADI), and The Society of American Shoulder and Elbow Surgeons Standardized Shoulder Assessment (ASES) score were used to conduct concurrent validity.
