Nottingham Klavikula Skorunun Türk Populasyonunda Geçerliliği ve Doğrulanması

Abstract

Aim: The aim of this study was to evaluate the validation and verification of the Nottingham Clavicle Score (NCS) in the Turkish population. Methods: Sixty-eight patients (12 females, 56 males; mean age: 37.1±13.3 years) who underwent surgery due to clavicle fracture or acromioclavicular separation were included in the study. The Turkish version of the NCS (NCS-Tr) was designed in accordance with the stages recommended by Beaton et al. Each patient completed the NCS-Tr twice at 7 to 10-day intervals to evaluate the test-retest reliability based on the interrater correlation coefficient, and Cronbach’s alpha was evaluated for internal consistency. Additionally, the Oxford Shoulder Score (OSS), Disabilities of the Arm, Shoulder, and Hand (DASH), Constant-Murley Score (CMS), and Short Form-36 (SF-36) Health Survey tests were completed by each participant to assess the correlation with the NCS-Tr. Results: The main score of the NCS-Tr was 79.71 ± 20.37. The other mean scores of CMS, OSS, and DASH were 84.14 ± 21.47, 38.34 ± 12.43, and 17.84 ± 22.47 respectively. The translation and adaptation of the NCS-Tr for a Turkish context required no major cultural adaptation. Internal consistency was high (Cronbach’s alpha: 0.933). Test-retest reproducibility was excellent (q=0.941, p<0.001). Conclusion: The NCS-Tr is a valid, reliable, shoulder-specific scale in the assessment of patient-reported outcome measures for the functional assessment of Turkish patients undergoing surgery due to clavicle fractures or acromioclavicular joint separation.
