Joint hypermobility and spectrum disorders explained

What joint hypermobility is

Joint hypermobility means that some or many of your joints move further than the usual range — you might be able to bend your thumb back to your wrist, straighten your elbows or knees beyond flat, or place your palms on the floor with straight legs. It is common, especially in children and young people, and often runs in families, reflecting the make-up of the body's connective tissue that gives joints their stretchiness. For most people, hypermobility is simply a normal variation that causes no symptoms and needs no treatment, and flexibility tends to reduce with age. The word only signals a problem when the extra flexibility comes together with symptoms such as pain or frequent injuries, which is when doctors talk about a hypermobility spectrum disorder rather than harmless flexibility.

When it causes problems

For some people, hypermobile joints bring troublesome symptoms. The most common is pain, often in the knees, hips, back, hands or other joints, which can come on after activity and sometimes becomes persistent. Joints may feel unstable, give way, or slip partly or fully out of place, and sprains and other injuries can happen more easily. People may tire quickly, feel clumsy, or notice their joints ache more the day after exercise. Some also experience symptoms beyond the joints, such as easy bruising, digestive problems, dizziness on standing, and anxiety, though these vary from person to person. When flexible joints are linked with ongoing pain, injuries or other symptoms that affect daily life, this pattern is described as a hypermobility spectrum disorder, sitting on a spectrum from mild to more disabling.

How it is assessed

Assessment starts with the story of the symptoms and a physical examination of how far the joints move. Clinicians sometimes use a simple scoring method that checks the flexibility of certain joints to gauge how widespread the hypermobility is, alongside asking about pain, injuries and how symptoms affect life. Importantly, part of the assessment is to look for features that might point to a rarer, specific connective tissue condition, some of which can affect the skin, blood vessels or other organs and need particular care; most people with hypermobility do not have these, but doctors stay alert to warning signs. There is no single test that confirms a hypermobility spectrum disorder — it is a clinical picture. The aim is to understand the impact on the individual and rule out other causes, so that support can be tailored.

How symptoms are managed

There is no cure for the way the joints are built, so management focuses on reducing symptoms and improving strength, stability and confidence. The cornerstone is exercise and physiotherapy: carefully building the muscles around the joints improves support and stability, and learning to move well and pace activity helps prevent flare-ups. Managing pain may involve simple measures, physiotherapy-led approaches and, where needed, advice from a clinician on other options. Occupational therapy can help with daily tasks, joint protection and, sometimes, supports or aids. Attention to good sleep, gradual fitness building and looking after mental wellbeing all help, as living with persistent symptoms can be wearing. Because a few people have symptoms beyond the joints, care is tailored to the individual, and more complex cases may be seen by specialists in rheumatology or physiotherapy.

Living well with hypermobility

Many people with joint hypermobility, including those with a spectrum disorder, live active, full lives, especially with the right approach. Staying active is important — although it can feel counter-intuitive when joints hurt, gentle, gradually increasing exercise that builds muscle strength protects the joints, whereas avoiding movement tends to make things worse over time. Learning your own limits, pacing activities, and warming up help avoid flare-ups. It can take time to find the right balance, and support from a physiotherapist, and sometimes an occupational therapist, is valuable. Connecting with others who understand, through support groups or charities, can help too. If new or worsening symptoms appear — particularly anything affecting the skin, heart, blood vessels or eyes — it is worth mentioning to your clinician so that other conditions can be considered and the right care arranged.
