The Beighton scale is probably the best known tool used to signpost hypermobility, but may also be the most misunderstood, and has limitations, even when properly applied ("Can you, or could you ever?" not just "Can you now?"). Originally designed as a research tool, it entered the diagnostic criteria for some conditions, but examines just nine of the 360+ joints in the human body.
It looks at just one direction of movement (ignoring knees and elbows that bend sideways, for example). Someone obviously hypermobile can fail to score a single point, while asymptomatic people can score a nine (and then some). So while Beighton score indicates hypermobility is present, it's of little use once that has been noted.
