THEORY | Shoulder Instability Tests

The video tutorial explores different types of shoulder impingement: primary, secondary, and internal. It discusses the clinical reasoning behind these conditions, focusing on the role of muscle weakness, joint laxity, and genetic factors. The tutorial details various instability tests used to diagnose anterior, posterior, and inferior shoulder instability, as well as labral tears. Key tests include the apprehension, relocation, surprise, jerk, and Kim tests. The video emphasizes the importance of these tests in identifying shoulder instability and impingement syndromes.

What is a common characteristic of primary shoulder impingement?

• Joint laxity

• Muscle stiffness

• Posterior shoulder pain

• Scapular dyskinesis

Which of the following is an objective finding for secondary impingement?

• Scapular dyskinesis

• Hooking of the acromion

• Weakness of rotator cuff muscles

• Posterior impingement test

What is the first test in the anterior instability test item cluster?

• Relocation test

• Apprehension test

• Surprise test

• Load and shift test

Why might some practitioners avoid the surprise test in the anterior instability cluster?

• It has low specificity

• It can cause further dislocation

• It is not part of the test item cluster

• It is not specific to shoulder instability

Which test is used to assess posterior shoulder instability?

• Sulcus sign

• Biceps load test Part 2

• Jerk test

• Apprehension test

What does a positive jerk test indicate?

• Anterior instability

• Lateral instability

• Inferior instability

• Posterior instability

What is the sulcus sign used to determine?

• Labral tear

• Posterior instability

• Anterior instability

• Inferior instability
