Clyde is administering a resisted muscle test to assess Beth’s shoulder injury. What does this test MOST likely involve?

A resisted muscle test checks how strongly a muscle works when the examiner applies resistance. Comparing the strength of Beth’s uninjured shoulder with her injured shoulder helps reveal weakness caused by the injury. Asking her to scratch her back tests range of motion, while lifting and lowering a can is a functional movement task.
