The test was devised in 1931 for detecting bicipital tendonitis. It is however now clear that the pain may arise from tenosynovitis, tendinopathy, or a SLAP lesion. It also assesses the ability of the transverse humeral ligament to hold the biceps tendon in the bicipital groove.
The physical examination: A combination of two sensitive tests and one specific test is useful to diagnose a SLAP lesion. Sensitive tests include: Compression rotation test; O’Briens test; Apprehension Test; Specific tests include: Speed’s test; Yergason’s test; Biceps load test II
The Yergason’s test was primarily designed to test the transverse humeral ligament, which holds a long biceps tendon in the bicipital groove. According to the RCT by Micheroli et al. (2015) it has a sensitivity of 32% and a specificity of 88% for biceps pathology.
7 lis 2021 · The Yergason's Test is used to test for biceps tendon pathology, such as bicipital tendonitis and an unstable superior labral anterior posterior (SLAP) lesion.The patient should be seated or standing in the anatomical position, with the humerus in a neutral position and the elbow in 90 degrees of flexion in a pronated position.
The accuracy of Speed's and Yergason's tests for diagnosing a SLAP lesion was poor in the only methodologically robust study reviewed. The likelihood ratios for these tests could not rule in, or rule out, the presence of a SLAP lesion when compared with arthroscopic results.
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.
Among the clinical tests for SLAP lesions that have been published to date, Yergason's test is the only one that shows a significant ability to influence clinical decision making, based on the results of the current analysis.
