In anti-gravity MMT for wrist flexion, what is the test position?

• A. Forearm Supinated with the Dorsal Surface Resting on the Table
• B. Forearm Pronated with the Palmar Surface on the Table
• C. Forearm in Neutral with the Hand on the Table
• D. Forearm Flexed at the Elbow with the Palm Facing Up

Answer: (A)

In this anti-gravity wrist flexion test, you want to isolate the wrist flexors (the muscles that bend the wrist toward the palm) and make sure the forearm is stabilized so the movement happens at the wrist and against gravity. Placing the forearm in supination with the dorsal surface of the hand resting on the table achieves that clearly: the supinated position positions the flexor muscles in a favorable line of pull and reduces the chance that forearm pronators or other muscles will substitute. Resting the dorsal surface on the table also stabilizes the forearm, preventing extraneous movement at the elbow or fingers and helping keep the motion focused at the wrist. If the forearm were pronated or the palm not supported, substitutions from pronators or finger flexors could contribute, or the test could be harder to isolate or to perform against gravity. This position therefore provides a stable, muscle-isolating setup for assessing anti-gravity wrist flexion strength.
