YERGASON'S TEST FOR SLAP LESIONS Primarily designed to test for the integrity of the transverse humeral ligament, this test is now more commonly used to detect SLAP lesions. While this test has the highest specificity in the literature amongst all SLAP tests with 95%, the low sensitivity of this test (12%) minimizes its clinical value. A positive test therefore increases the odds for a SLAP lesion by only 2.49 and a negative test basically does not alter the post-test probability for the presenc

MATLES TEST TO DIAGNOSE ACHILLES TENDON RUPTURE Matles originally described the knee flexion test in 1975. Reiman et al. (2014) conducted a systematic review with meta-analysis on clinical tests used in the diagnosis of achilles tendon pathology. Their findings for this test? A sensitivity of 88% and a specificity of 85%. The associated likelihood ratios would alter the post-test probability to a moderate degree and the included study had a fairly high risk of bias which is why the clinical valu
