In gravity-minimized MMT for Wrist Extension, what is the forearm position and stabilization?

• A. Forearm in neutral; ulnar border of the hand resting on a table top with the wrist in neutral. The fingers should be relaxed. Stabilization: The clinician stabilizes the forearm against the table top.
• B. Forearm in neutral; ulnar border of the hand resting on a table top with the wrist in neutral. The fingers should be clenched. Stabilization: The clinician stabilizes the forearm against the table top.
• C. Forearm pronated; palm resting on the table top.
• D. Forearm in neutral; dorsal surface resting on the table

Answer: (A)

In a gravity-minimized wrist extension test, you place the forearm supported on a stable surface with the forearm in a neutral orientation. This setup allows the patient to attempt to extend the wrist without gravity helping or hindering the movement, so the test isolates the wrist extensor muscles rather than whole-arm effort. Resting the ulnar border of the hand on the table provides a stable contact point to anchor the hand and helps prevent extra movement at the wrist other than pure extension. Letting the fingers stay relaxed avoids recruiting finger flexors or gripping patterns that could skew the measurement. Stabilization is crucial: the clinician holds the forearm steady against the table so the motion remains at the wrist and doesn’t involve the elbow or shoulder, and to prevent slipping or rotation of the forearm. This combination—neutral forearm, supported hand, relaxed fingers, and firm forearm stabilization—yields an isolated, gravity-minimized assessment of wrist extensor strength. Options with the fingers clenched would engage finger flexors and grip, altering the test results. Pronating the forearm or letting the dorsal surface rest on the table changes alignment and the mechanics of the movement, making it harder to isolate the wrist extensors in a gravity-minimized position.
