Definition of Hypermobile joints:

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

Considerations:

Children generally tend to be more flexible than adults, but those with hypermobile joints can flexing and extend their joints beyond what's considered normal. The movement is done without undue force and without discomfort.

Children with hypermobile joints also frequently have flat feet.

Common Causes:

Hypermobile joints occur in some very rare medical conditions, but can also occur in otherwise healthy and normal children. Conditions associated with hypermobile joints include:

• Cleidocranial dysostosis
• Down syndrome
• Ehlers-Danlos syndrome
• Marfan syndrome
• Morquio syndrome
