For a weight-bearing hand position used during a transfer, which shoulder action helps stabilize the elbow in extension?

• A. Wrist flexion
• B. Shoulder flexion
• C. Shoulder extension
• D. Forearm pronation

Answer: (B)

When bearing weight through the hands during a transfer, the elbow stays extended best when the shoulder is in a forward flexed position. Shoulder flexion helps position the arm so the humerus aligns with the forearm and the scapulothoracic region can stabilize the shoulder girdle, creating a solid base that resists the elbow dropping into flexion under load. This proximal stabilization is key for maintaining an extended elbow as you push through the hand.

Wrist flexion doesn’t impact elbow stability in this scenario, forearm pronation mainly changes grip and distal alignment, and shoulder extension moves the arm behind the body, which can undermine the stable alignment needed to keep the elbow extended during the transfer.
