In gravity minimized MMT for Shoulder Horizontal Adduction, stabilization is provided by which?

• A. Contralateral Shoulder
• B. Opposite Scapula
• C. Weight of Trunk on Table
• D. Clinician Stabilizes Tested Side

Answer: (A)

In gravity-minimized MMT, stabilization keeps the trunk and shoulder girdle fixed so the movement truly isolates the target joint and muscle. For shoulder horizontal adduction, you want a stable base that prevents the thorax or scapula from moving as the arm crosses the chest. Using the opposite (contralateral) shoulder as the stabilizing point provides that anchor, locking the torso in place and allowing the examiner to sense the true strength of the shoulder adductors without cheating from trunk or scapular motion. The other options don’t offer the same stable anchor. Stabilizing the opposite scapula doesn’t reliably fix the entire thorax for this test, the weight of the trunk on the table is a passive factor rather than a deliberate stabilization maneuver, and having the clinician stabilize the tested side can alter the mechanics and make it harder to isolate the intended muscle action.
