Hypermobility is a term used to describe “loose joints” or joints that stretch farther than what is normal.  For example, some people with hybermobility will be able to stretch their thumb backwards where it touches the wrist while others can put their leg behind their head.  Researchers have found that certain inherited genes (that are predisposed) are the root of hypermobile joints.  In addition, genes responsible for the production of collagen may also play a role. The condition is considered benign and harmless and occurs in about 10-15% of children.  Hypermobility does not have any symptoms and does not require any treatment.
