“…Given the difficulties in reliably classifying SLAP lesions based on arthroscopic videos [8], it is not surprising that physical examination maneuvers [5,18] and MRI findings [21] are reported to be unreliable in correctly diagnosing SLAP lesions. In two systematic reviews of physical examination reliability and validity for diagnostic accuracy of SLAP tears [5,12], the methodologically robust studies determined that Speed's and Yergason's tests (among all maneuvers) showed sensitivity of 32% and 43% and specificity of 79% and 75%, respectively [5,12].…”
