Validation of the shoulder36 for the activities of daily living with shoulder disorders

抄録

[Purpose] The Shoulder36 (V 1. 3) is a regional questionnaire in Japan that has not been validated as a functional evaluation of the shoulder via a thorough comparison with other questionnaires (e.g., QuickDASH). The purpose of this study was to test the reliability, validity, and responsiveness of the Shoulder36 (V 1. 3). [Subjects and Methods] A series of 46 patients with upper extremity disorders completed the Shoulder36 (V 1. 3) and the QuickDASH Japanese version (QuickDASH-JSSH). The reliability of the Shoulder36 was assessed for consistency and validity. The correlation coefficients between the Shoulder36 (V 1. 3) and the QuickDASH-JSSH were obtained. [Results] The total of the Cronbach’s alpha coefficients for the Shoulder36 (V 1. 3) was 0.98. The intraclass correlation coefficients for the six domains of the Shoulder36 (V 1. 3) were similarly high, ranging from 0.81 to 0.94. The correlations between the six domains of the Shoulder36 (V 1. 3) and the three domains of the QuickDASH subscales ranged from −0.43 to −0.78. [Conclusion] The Shoulder36 (V 1. 3) was able to evaluate the relationship between activities of daily living and shoulder joint function with the same degree of accuracy but in more detail than QuickDASH-JSSH. Therefore, it should prove to be a valuable asset in physiotherapy plans and have multiple research applications.
