In gravity-minimized MMT for Wrist Flexion, which describes the forearm position?

• A. Forearm in neutral; the ulnar border of the hand resting on a table top with the wrist in neutral
• B. Forearm pronated; the ulnar border of the hand resting on a table top with the wrist in neutral
• C. Forearm supinated; the ulnar border of the hand resting on a table top with the wrist in neutral
• D. Forearm in neutral; the radial border of the hand resting on a table top with the wrist in neutral

Answer: (A)

Gravity-minimized testing aims to remove gravity’s influence so you can feel the true strength of the wrist flexors. Keeping the forearm in neutral position prevents any torque from rotation that could bias the test, while the wrist staying neutral ensures there’s no inherent flexion or extension bias. Placing the ulnar border of the hand on the table provides a stable contact base and helps keep the finger flexors from contributing through gripping. If the forearm were pronated or supinated, gravity could help or resist the motion in a way that doesn’t reflect pure wrist flexor strength. Using the radial border for contact would also alter stabilization and the direction of any unintended torque. So, forearm neutral, wrist in neutral, with the ulnar border resting on the table best isolates wrist flexors in gravity-minimized testing.
