What tests are used to assess the integrity of the rotator cuff?

The correct answer focuses on the use of specific tests designed to evaluate the integrity of the rotator cuff, which is essential for diagnosing shoulder injuries. The Hawkins-Kennedy test and Neer's test are both physical examination maneuvers that specifically target the rotator cuff, particularly the supraspinatus muscle, which is commonly involved in rotator cuff tears.

The Hawkins-Kennedy test is performed by flexing the shoulder to 90 degrees and then internally rotating the arm, which can elicit pain if there is impingement of the rotator cuff tendons. This test is particularly useful in assessing for shoulder impingement syndrome, a common condition that often results from rotator cuff injuries.

Neer's test is performed by stabilizing the scapula and then raising the arm in front of the patient. If this maneuver produces pain, it suggests that the rotator cuff tendons are being impinged upon, which corroborates the presence of a rotator cuff injury or tear.

The other tests mentioned in the other options are not appropriate for assessing the rotator cuff. For example, the valgus stress test and Lachman test are used primarily to evaluate the integrity of the medial collateral ligament and the anterior cruciate ligament, respectively,
