The resting hand splint positions the hand in functional position. Which description matches this position?

• A. Wrist neutral with thumb in slight opposition and abduction; fingers slightly flexed
• B. Wrist flexed with thumb tucked under
• C. Wrist extended in maximal extension with fingers curled
• D. Wrist pronated with palm down

Answer: (A)

The resting hand splint is designed to hold the hand in a posture that supports everyday grasp and prevents contractures. In this functional position, the wrist sits near neutral to a slight extension, the thumb is in slight opposition and abduction so the thumb pad can reach and oppose objects, and the fingers are in gentle flexion rather than extended or curled. This combination places the hand in a ready-to-grasp posture, balancing intrinsic and extrinsic muscle length and keeping the thumb poised for grip.

That’s why the description describing a wrist in neutral with the thumb in slight opposition and abduction while the fingers are slightly flexed fits best. Positions that bend the wrist (flexed or maximally extended), tuck the thumb under, or rotate the forearm in pronation disrupt the ability to grip and do not reflect the resting functional posture.
