Beighton 1973: 9 points; 2017 EDS age thresholds; no automatic new diagnosis

Beighton assesses generalized joint hypermobility; it does not by itself diagnose hypermobile Ehlers–Danlos syndrome. In the 2017 classification, cutoffs are at least 6 in prepubertal children and adolescents, 5 in pubertal individuals and adults up to 50 years, and 4 above 50 years. Surgery, amputation, wheelchair use, injuries and other acquired limitations may prevent maneuvers; document them. A history of hypermobility can complement the examination, but the 2017 classification notes that the five-question historical questionnaire had not been validated in children. Diagnosis of hEDS requires all three sets of criteria and exclusion of other causes.

Documented formula

Transcribed from the source or a recorded revision; this is not a clinical recommendation.

1 point per positive maneuver, each side when bilateral: fifth finger (2), thumb (2), elbow (2), knee (2), trunk flexion (1). Total 0 to 9.

Generalized hypermobility (2017): ≥6 in prepubertal children/adolescents; ≥5 from puberty to 50 years; ≥4 over 50 years.
