Which description applies to gravity-minimized wrist flexion?

• A. Forearm in Neutral; Ulnar Border on Table; Wrist in Neutral
• B. Forearm Pronated; Palm on Table
• C. Forearm Supinated; Wrist Extended
• D. Forearm Flexed; Fingers Clenched

Answer: (A)

In gravity-minimized testing, you remove the influence of gravity by stabilizing the limb on a surface so the joint won’t move on its own under its weight. For wrist flexion, the best setup is the forearm resting on a flat surface in neutral, with the ulnar border on the table and the wrist kept in neutral. This arrangement supports the weight of the forearm and hand, removing a strong gravitational drive toward flexion or extension, so any movement comes from the patient’s active effort rather than gravity. The contact of the ulnar border helps stabilize the arm and prevent unwanted motions, keeping the wrist neutral and isolating the test. Other positions would allow gravity to influence the movement more directly—for example, changing forearm rotation or letting the wrist sit in a more extended or flexed posture would create a gravitational moment that either assists or opposes flexion, which defeats the purpose of a gravity-minimized assessment.
