Hypermobility refers to the ability of a persons joints to move beyond the normal range of motion. Joint hypermobility syndrome (JHS) is a genetic connective tissue disorder that causes extreme flexibility along with pain and other symptoms. People with JHS have loose or weak ligaments that hold their joints together, which can cause pain, stiffness, sprains, strains, and dislocations. However, being hypermobile does not necessarily mean that a person will experience pain or difficulty. In fact, many people with hypermobile joints do not have any problems, and some people, such as dancers, gymnasts, and musicians, may even benefit from increased flexibility.

Hypermobility can be diagnosed by a doctor who will examine a person to see how flexible their joints are and check their skin, eyes, and heart. If a person has hypermobility that causes pain or other symptoms, they may have JHS or a hypermobility spectrum disorder (HSD) . HSDs are connective tissue disorders that cause joint hypermobility, instability, injury, and pain, as well as other problems such as fatigue, headaches, GI problems, and autonomic dysfunction.

Treatment for hypermobility and JHS/HSD may include gentle exercise, physiotherapy, and pain management techniques. It is important to work with a healthcare provider to protect the joints and manage pain. People with hypermobility should avoid overextending their joints and doing repetitive exercises or activities. Maintaining a healthy weight, wearing supportive shoes, and using special insoles in shoes if recommended by a podiatrist can also help.
