The Beighton index is scored based on which maneuvers?

• A. Hyperextension of the knee beyond 10 degrees
• B. Passive dorsiflexion of the little finger beyond 90 degrees
• C. Forward trunk flexion with palms on floor
• D. All of the above

Answer: (D)

Hypermobility is assessed with a simple scoring system, the Beighton index, which uses a few specific movements to gauge joint laxity. These maneuvers include bending the little finger back beyond 90 degrees, extending the knee beyond 10 degrees, and forward trunk flexion with the palms flat on the floor, among others like thumb-to-forearm and elbow hyperextension. Each positive maneuver contributes to the score, and the combination covers the range of joints tested. The options given—the knee hyperextension, the little finger dorsiflexion beyond 90 degrees, and the forward trunk flexion with palms on the floor—are all part of the Beighton criteria, so “All of the above” is the correct choice.
