PATINO, Osvaldo et al. Shoulder outcome measures: 4 Functional scales and concurrent reliability. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2011, vol.76, n.1, pp.41-46. ISSN 1852-7434.

Background: The purpose of our study was to compare the concurrent reliability of 4 commonly used outcome scales for rotator cuff surgery and shoulder pain syndrome. Methodology: 16 female and 7 male patients with rotator cuff surgery, and 7 female and 10 male patients with shoulder pain syndrome were analyzed. Four professionals blindly applied the following scales: Simple Shoulder Test (SST), Constant and Murley Scale (Constant), University of California Los Angeles Shoulder Score (UCLA) and American Shoulder and Elbow Surgeons Shoulder Score Index (ASES). The Intraclass correlation coefficient (ICC) and 95% Confidence Interval (CI) and p < 05 significance level were used for statistical purposes. Results: The dominant shoulders were affected in 65% of the patients. The ICC(CI 95%) between scales was: SST vs Constant 0.39 (-15.3; 0.68) .064, vs ASES 0.29 (-0.34; 0.62); vs UCLA 0.56 (0.17; 0.77). Constant vsASES 0.834 (0.69; 0.91); vs UCLA 0.706 (0.44; 0.85) and ASES vs UCLA 0.679 (0.39; 0.83). Conclusions: Our study found no concurrent reliability between SST and C-M, and between SST and ASES. Reliability was moderate between SST and UCLA, between C-M and UCLA and between ASES and UCLA. The highest reliability was observed comparing C-M and ASES. We estimate that when using both scales, the results obtained should be similar.
