During elbow flexion MMT in anti-gravity, where should the examiner stabilize the limb?

• A. Stabilize the humerus.
• B. Stabilize the forearm.
• C. Stabilize the elbow joint.
• D. No stabilization is used.

Answer: (A)

When testing elbow flexion against gravity, you want to isolate the elbow flexors and prevent any movement from other joints that could contribute to the motion. Stabilizing the humerus anchors the upper arm so the shoulder and scapulothoracic joints can’t drive the motion. This keeps the test focused on elbow flexion, with resistance applied to the forearm while the proximal arm remains stationary. Stabilizing the forearm or the elbow joint would interfere with the movement you’re assessing or fail to prevent compensatory motion, and no stabilization would allow the entire limb to move unpredictably. So, stabilizing the humerus provides the proper control to measure the elbow flexors accurately.
