Joint hypermobility

Also called Joint hypermobility syndrome, Hypermobility spectrum disorder, or Double-jointed

Joint hypermobility means some or all of your joints have an unusually large range of movement. Many people with hypermobile joints have no problems. When it causes symptoms such as pain, stiffness or frequent sprains and dislocations, it may be called hypermobility spectrum disorder. It often runs in families.

What it is

Exercises to strengthen muscles and improve fitness, guided by a physiotherapist, are the main treatment.

Sometimes hypermobility is part of a wider condition, such as Ehlers-Danlos syndromes.

Common signs

  • Joints that bend further than usual
  • Pain and stiffness in joints and muscles
  • Frequent sprains or dislocations
  • Tiredness
  • Poor coordination

How it is usually diagnosed

  • Examination using the Beighton score
  • Questions about symptoms and family history

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Beighton score
  • Physiotherapy notes and exercise plans
  • Rheumatology letters

Questions to ask your doctor

  • Could this be part of another condition?
  • Which exercises are safe for me?
  • How can I avoid injuries?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • A joint that dislocates and does not go back, or is very swollen and painful after injury: get it checked the same day
