Which Beighton criterion specifically tests the little finger?

Explanation:
Beighton scoring looks for generalized joint hypermobility with specific maneuvers, and the one that targets the little finger is the passive dorsiflexion of the little finger beyond 90 degrees. In this test, the examiner moves the little finger backward at the metacarpophalangeal joint until the angle exceeds 90 degrees, which directly assesses the small finger’s joint laxity as part of overall hypermobility. The other options involve different joints or movements—knee and elbow hyperextension assess those joints’ laxity, while forward trunk flexion with palms on the floor evaluates overall flexibility rather than a specific finger joint.
