The video tutorial covers the test item cluster for diagnosing subacromial impingement syndrome (SAPS), focusing on three key tests: the Hawkins Kennedy test, the painful arc test, and the resisted infraspinatus test. Each test's psychometric properties, such as sensitivity and specificity, are discussed. The video explains how combining these tests can improve diagnostic accuracy by increasing the positive likelihood ratio. Detailed procedures for each test are provided, along with their utility in differentiating between SAPS and rotator cuff tears.

Describe the procedure for conducting the Hawkins Kennedy test.

What is the sensitivity and specificity range of the resisted infraspinatus test?

What does a negative result in the resisted infraspinatus test indicate?
