Hypermobility Syndrome

Hypermobility syndrome is too much movement at a joint. It is sometimes referred to as being “double jointed” or “loose jointed.” 

Examples of hypermobility syndrome.

It is most common in young children who are more flexible than older children and teenagers. It usually affects movements in the shoulders, elbows, wrists, fingers and knees, but can be seen in all joints. The most common form, benign hypermobility of childhood, is due to age and genetics.

You may have hypermobility syndrome if you have extreme movement of a joint. Although hypermobility is common, it can be linked with syndromes such as Down syndrome, Ehlers-Danlos syndrome, Marfan syndrome, Williams syndrome and others.

A doctor’s exam can diagnose hypermobility syndrome. There are some tests that can be done if there is concern for an underlying medical problem. However, most children with hypermobility have a nonthreatening form.

Many factors cause hypermobility. Children with the benign form usually outgrow their hypermobility as they get older. It is caused from abnormal stretch in ligaments, tendons and connective tissue that hold the skeleton together.

There is no cure for hypermobility. Hypermobility usually gets better as kids age. Keeping muscles strong and limiting over-stretching of your muscles and joints can prevent pain and dislocations.

Some people with hypermobility syndrome can have pain in their arms and legs. Others are at risk for dislocation of their kneecaps and shoulders. 

Hypermobility syndrome is due to your genes and cannot be prevented.
