The compression load used in the "jerk test" is applied to which part of the body?

• A. Elbow
• B. Shoulder
• C. Wrist
• D. Finger

Answer: (A)

The jerk test is primarily used to assess the integrity and function of the shoulder, particularly evaluating the presence of a labral tear or issues with the shoulder joint stability. During this test, a compression load is applied to the shoulder to elicit any symptoms or signs related to labral injuries. Applying the load to the elbow does not serve the purpose of the jerk test; therefore, the focus remains on the mechanics of the shoulder joint. The test involves specific maneuvers where the shoulder is put through various ranges of motion under compression, meant to replicate the conditions that a labral tear would create during functional activities. This targeted approach effectively assists in diagnosing shoulder pathologies rather than issues with the elbow, wrist, or fingers.
