Benign Hypermobility Syndrome

Benign joint hypermobility syndrome is a connective tissue disorder characterized by joints that easily move beyond the normal range. People with joint hypermobility are often called "double-jointed." This is common and usually not problematic, but in some people, typically children, it causes pain.

Symptoms

• Children with benign hypermobility syndrome may complain of pain after exercise or of pain waking them at night. Traditionally, this has been referred to as "growing pains," says the Cleveland Clinic.

Location

• Benign hypermobility syndrome pain is more common in the legs and arms, and most often involves large joints such as the knees or elbows.

Pain Causes

• Joint hypermobility may cause wear and tear on the joints and strains in nearby muscles, according to the Journal of the American Osteopathic Association (JAOA). Children who experience pain from hypermobility may have reduced proprioception, or awareness of where their body parts are located, which can lead to joint trauma.

Time Frame

• Symptoms usually improve by the teen years, because increased strength and size of joints and muscles reduces joint laxity. Through experience, children also learn which movements cause pain. Some people, however, continue to have discomfort throughout their lives.

Treatment

• Joint pain from benign hypermobility syndrome can be treated with medication if the parent and physician agree it is appropriate. Modifying activity may be necessary, and children can be taught stretching and strengthening exercises for the joints, says that JAOA.
