In gravity minimized MMT for Shoulder Abduction, which stabilization is used?

• A. Clinician Stabilizes Opposite Shoulder
• B. Weight of the Trunk on the Table
• C. Arm Weight
• D. No Stabilization

Answer: (B)

In gravity-minimized muscle testing for shoulder abduction, stabilization comes from the body's own support rather than the examiner actively holding or stabilizing. Placing the patient supine with the arm positioned so the limb is supported on the table allows the weight of the trunk to press the scapula firmly against the thorax. This natural contact stabilizes the shoulder girdle and prevents compensatory or extraneous movement, isolating the shoulder abductors for assessment without gravity pulling the arm downward. Why this setup is best: using the trunk’s weight on the table provides a stable base that confines movement to the tested muscles, so you aren’t relying on the clinician to hold the opposite shoulder or on the arm’s own weight to resist gravity. The arm’s weight would tend to influence movement rather than stabilize, and no stabilization would permit unwanted scapular or trunk motion.
