The sensitivity and specificity of findings for Subscapularis Tear are listed below. See the left navigation bar to change the display.

Pre-Test Probability (Prevalence): %.	Post-Test Probability (Predictive Value): %.	Switch to display mode.
Note that calculating probabilities from more than one** finding is inherently inaccurate because findings are not independent. (For example, using two positive findings that share a common pathogenesis is likely to overestimate the true probability.)

The patient is examined in standing and is asked to place their hand behind their back with the dorsum of the hand resting in the region of the mid- lumbar spine. The dorsum of the hand is raised off the back by maintaining or increasing internal rotation of the humerus and extension at the shoulder. Study: Joint Bone Spine. 2008 Dec 5. PMID: 19059801
