Definition    Return to top

Hypermobile joints are joints that move beyond the normal range with little effort. The joints that are most commonly hypermobile are the elbows, wrists, fingers, and knees.

Hypermobile joints occur in some very rare medical conditions, but can also occur in otherwise healthy and normal children. Children generally tend to be more flexible than adults, but those with hypermobile joints are capable of flexing and extending beyond normally observed limits for that particular joint. The movement is accomplished without undue force and without discomfort. Children with hypermobile joints also frequently have flat feet.

Home Care    Return to top

There is no specific care for the hypermobility. In many cases, people with hypermobile joints are at an increased risk for joint dislocation and other problems, and extra care may be needed to protect the joints. Consult your health care provider for specific recommendations.

Hypermobile joints often accompany other symptoms that, taken together, define a specific syndrome or condition. A diagnosis is based on a family history, medical history and thorough physical evaluation.

Medical history questions that help document hypermobile joints in detail may include:

• When was it first noticed?
• Is it getting worse or more noticeable?
• Are other symptoms are also present, such as swelling or redness around the joint?
• Is there any history of joint dislocation, difficulty walking, or difficulty using the arms?

The physical examination will include detailed examination of the muscles and skeleton. The joints may be moved to determine the direction and extent of mobility.

Diagnostic testing will vary depending on what condition is suspected.
