Hypermobility (also called double-jointedness, hypermobility syndrome or hyperlaxity) describes joints that stretch farther than is normal. For example, some hypermobile people can bend their thumbs backwards to their wrists, or bend their knee joints backwards. It can affect a single joint or multiple joints throughout the body.
Hypermobility generally results from one or more of the following:
- Misaligned joints
- Abnormally-shaped ends of one or more bones at a joint
- A Type 1 collagen defect results in weakened ligaments, muscles & tendons. This same defective process also results in weakened bones which may result in osteoporosis and fractures
- Abnormal joint proprioception (an impaired ability to determine where in space parts of the body are, and how stretched a joint is)
