Receiver operating characteristic (ROC) analysis a, internal rotation; b, external rotation; c, total arc. According to ROC analyses, the cutoff values for diagnosis of shoulder impingement syndrome were 47° for internal rotation (sensitivity, 0.56; specificity, 0.81; sensitivity - [1-specificity], 0.36; AUC, 0.71), 41° for external rotation (sensitivity, 0.83; specificity, 0.69; sensitivity - [1-specificity], 0.53; AUC, 0.82), and 86° for total arc (sensitivity, 0.83; specificity, 0.83; sensitivity - [1-specificity], 0.67; AUC, 0.88)
