Anterior Shoulder Instability Tests | Apprehension, Relocation, & Surprise Tests

The video tutorial covers special tests for diagnosing anterior shoulder instability, focusing on the apprehension, relocation, and surprise tests. The apprehension test involves passive external rotation of the shoulder to detect apprehension or pain, indicating instability. The relocation test follows, applying a posterior force to the humeral head to reduce symptoms. The surprise test, rarely used due to risks, involves releasing the posterior force without warning. The video emphasizes the order of tests and their clinical significance, highlighting the apprehension and relocation tests' high specificity.

What is the primary reason the surprise test is rarely performed in clinical practice?

• It is too time-consuming.

• It requires special equipment.

• It can cause further dislocation and pain.

• It is not mentioned in the literature.

During the apprehension test, what position should the patient's forearm be in?

• Pronation

• Flexion

• Supination

• Neutral

What indicates a positive result in the apprehension test?

• Improved shoulder stability

• No change in symptoms

• Apprehension or pain during external rotation

• Increased range of motion

What is the main purpose of the relocation test?

• To reduce apprehension or pain by repositioning the humeral head

• To confirm shoulder dislocation

• To increase shoulder flexibility

• To test the strength of shoulder muscles

What should be done if the apprehension test is negative?

• Stop further testing

• Perform the surprise test

• Proceed to the relocation test

• Repeat the apprehension test

What is the starting position for the surprise test?

• A neutral shoulder position

• The same as the relocation test

• A fully flexed elbow position

• The same as the apprehension test

What is a potential risk of performing the surprise test?

• Increased shoulder stability

• Full dislocation or further subluxation

• No change in symptoms

• Improved range of motion
