Which index assesses hypermobility?

• A. Beighton index
• B. Goniometer score
• C. Shoulder flexibility index
• D. Hyperextension index

Answer: (A)

Beighton score is a quick screening tool specifically designed to assess generalized joint hypermobility by testing multiple joints for excessive motion. It uses a set of simple maneuvers, including bending the trunk to place the palms on the floor with straight knees, hyperextension of the elbows and knees, and the ability of the little fingers to extend beyond 90 degrees and thumbs to touch the forearms. Each positive finding adds to a total score (up to 9), so a higher total indicates greater hypermobility. This broad, multi-joint approach is why it’s the best index for identifying hypermobility. In contrast, a goniometer measures ROM at individual joints, which doesn’t capture the overall hypermobile pattern, and the other named indices aren’t standard tools for this purpose.
