Accuracy of the shoulder clinical tests and ultrasonography in the diagnosis of supraspinatus tendon lesions

Abstract

The shoulder clinical tests are important for the diagnosis of the rotator cuff lesions; moreover, currently there is an abusive increase in requests for the shoulder image exams, especially the ultrasound and magnetic resonance, for patients complaining of shoulder pain. The aim of the study will be to evaluate the accuracy of these shoulder tests in the diagnosis of supraspinatus tendon lesions. An accuracy study will be done in patients of both genders, over 18 years of age, with a complaint of shoulder pain for at least 1 month, compared to ultrasound and magnetic resonance imaging of the shoulder that will be performed. The tests performed will be: the Jobe test, full can test, drop arm test, external rotation against resistance test, Patte test, Hawkins-Kennedy, Yocum, Neer signal, Speed test, painful arc and cross body adduction test; and then, the patients will undergo the imaging of the shoulder: ultrasound and magnetic resonance. The sensitivity, specificity, positive predictive value, negative predictive value, accuracy and likelihood ratio of these tests will be calculated. (AU)
