According to general fitting rules, the handgrip height should correspond to which landmark?

• A. Ulnar styloid = handgrip height
• B. Elbow flexion 90 degrees
• C. Standing height
• D. Shoulder height

Answer: (A)

Handgrip height is set to align with a palpable bony landmark—the ulnar styloid process—when the person stands with the arm relaxed at the side. This placement keeps the forearm in a neutral, functional position with a comfortable, slight elbow flexion, enabling a natural grip and stable weight transfer without overloading the shoulder or wrist. Using the ulnar styloid as the reference point provides a consistent, reproducible height across individuals, which is why it’s preferred over standing height, shoulder height, or forcing a 90-degree elbow angle. The other references would place the grip too high or too low for many people and can lead to awkward posture and inefficient use of the device.
