Quick version
Hypermobility means that the body's connective tissue is more flexible than normal, which allows the joints to bend further than usual. When this hypermobility leads to pain, instability and repeated injuries, it is called hypermobility spectrum disorder (HSD) or the hereditary condition hypermobile Ehlers-Danlos syndrome (hEDS). The problems often extend beyond just the joints and can cause profound fatigue, stomach problems, headaches and dizziness. The diagnosis is made clinically through medical history and mobility tests such as the Beighton score, while blood tests are mainly used to rule out nutritional deficiencies or other diseases. The path to a functioning everyday life is rarely about more stretching, but about adapted strength and stability training that helps the muscles to actively support and protect the unstable joints.
Hypermobility may sound like an advantage. You may have always been able to do the splits, bend your thumb back to your forearm or impress with unusually soft joints. But when that same mobility is followed by aching knees, recurring sprains or a feeling that your body never quite holds together, hypermobility becomes something completely different from “flexibility”.
Many people who seek help for joint pain are first told that they are just overly mobile. For some, this is true and does not cause any major problems. For others, hypermobility is part of a broader condition where pain, fatigue and instability affect both everyday life, training and work ability.
What does hypermobility mean?
Hypermobility means that one or more joints move more than usual. This is usually due to the body's connective tissue being more pliable than average. Connective tissue is found in, among other things, ligaments, tendons, skin and supporting tissue around organs.
For many, this is just a normal variation. Children, women and people with certain hereditary traits often have greater mobility in their joints without being sick. Problems arise when hypermobility is combined with pain, repeated injuries, joint instability or other physical symptoms.
Generalized joint hypermobility is a measure of the hypermobility itself. If the hypermobility causes discomfort but does not meet the requirements for hypermobile Ehlers-Danlos syndrome (hEDS), the condition is called hypermobility spectrum disorder (HSD). HEDS is in turn an inherited connective tissue disease in which joint hypermobility is combined with other specific physical symptoms.
When does hypermobility become a problem?
It is easy to wonder why pain occurs even though you should actually be mobile and strong. The answer is that a joint needs a balance of both mobility and stability. When ligaments and supporting tissue provide too little passive support, the muscles must compensate and work harder to keep the joint in the correct position.
This can cause a nagging ache after a day of work, pain after exercise, or a feeling that the shoulder, knee, or ankle is “slipping.” Small, repeated overloads can also irritate tendons and muscle attachments. Over time, the body may react with tension, fatigue and poorer movement control rather than with clear swelling or inflammation.
Typical complaints are:
joint pain that is worsened by strain or prolonged static positions
recurrent sprains, subluxations or the joint feeling unstable
muscle fatigue and the need to “compensate” in other parts of the body
pain in several joints at the same time, often knees, ankles, hips, fingers or shoulders
increased pain after activity even though X-rays or blood tests are normal.
For someone in an office, it may be noticeable as neck and shoulder pain after a day at the computer. For someone who exercises, it may instead be recurrent overuse, knee pain when running or shoulder problems during strength training. Employers often see the problem as recurring strain problems without a clear individual injury.
Symptoms of hypermobility are not just about joints
Hypermobility can be more than joint pain. Especially with hEDS and certain forms of the hypermobility spectrum, fatigue, sleep problems, headaches, gastrointestinal problems and symptoms from the body's autonomic nervous system, such as palpitations or dizziness when standing up, are also seen.
This does not mean that everyone with hypermobile joints has a syndrome or a systemic disease. However, if the joint pain is combined with, for example, easy bruising, soft skin, recurrent dislocations, pronounced fatigue or problems from multiple organ systems, the picture needs to be assessed more broadly.
Many also describe feeling misunderstood for a long time. When tests are normal and the joint looks "fine", the symptoms can be misinterpreted as nonspecific. At the same time, it is known that the pain of hypermobility is real and can be due to both mechanical overload, repeated micro-injuries and altered pain processing in the nervous system.
How is hypermobility diagnosed?
The diagnosis is mainly based on medical history and physical examination. The doctor or physiotherapist asks about pain, sprains, dislocations, heredity and symptoms from other parts of the body. Joint hypermobility is then assessed, often with the Beighton score, which tests several typical movements in the fingers, elbows, knees and spine.
The Beighton score is a useful tool but not the whole truth. A person may have clear problems with hypermobility even if the score is not high at the time of the examination, especially if mobility has decreased with age, pain or previous injuries. Therefore, the score is always weighed together with symptoms, previous mobility and other clinical findings.
If hEDS is suspected, the diagnosis is made based on established clinical criteria. Today, there is no confirmed genetic test that can alone determine hEDS, unlike several other forms of Ehlers-Danlos syndrome where genetic analysis can be indicative. Genetic investigation is therefore mainly relevant when the symptoms suggest another hereditary connective tissue disease or when there are warning signs, such as unusual vascular fragility or clear skin fragility.
Blood tests are not used to prove hypermobility, but they can be important to rule out other causes of pain and fatigue. In practice, this may involve assessing inflammation, blood status, thyroid, iron deficiency, vitamin deficiency or other conditions that can amplify the symptom picture.
Treatment for hypermobility: stability before stretching
The most well-documented treatment is individually adapted training. The goal is not to become even more mobile, but to build strength, improve coordination and give the joint better active control. This is especially true for the torso, hips, shoulders and ankles, where stability often determines how the load is distributed in the rest of the body.
For many, it feels unexpected that the treatment is often the opposite of what they themselves have tested. Anyone who feels stiff despite hypermobility easily starts to stretch more, but too much stretching can worsen the instability. Instead, low to moderate strength training, balance exercises, gradual cardio training and a clear dosage of activity and recovery often help.
Physiotherapy can also include:
proprioception training, i.e. the body's ability to sense the position of the joint
technique adjustment when walking, running, strength training or working
orthosis, taping or support for particularly unstable joints
ergonomic adaptations at home and at work
strategies to avoid overload without becoming inactive.
Pain treatment needs to be adapted to the cause. Acute injuries are managed differently than long-term pain. In the case of long-term problems, a combination of exercise, sleep therapy, activity planning and sometimes pain rehabilitation often works better than relying solely on medication.
When should you seek care and when can testing be valuable?
You should seek care if you have recurrent joint dislocations, new severe pain, significant swelling, neurological symptoms or if hypermobility affects work, exercise or sleep. The same applies if you have several simultaneous problems such as dizziness, severe fatigue, stomach problems or palpitations. In this case, you need to determine what is related to hypermobility and what may have another cause.
Testing cannot measure hypermobility directly, but it can provide important information about things that affect pain tolerance, recovery and energy. Examples are anemia, iron deficiency, vitamin D deficiency, thyroid disorders or other abnormalities that cause an already overloaded body to function less well than it otherwise would. For those with long-term pain or unexplained fatigue, a health check can therefore be a reasonable complement to clinical assessment.
Hypermobility teaches us that more mobility does not always mean better function. In many cases, the way forward is about building a body that feels reliable, not about squeezing out even greater ranges of motion. When you understand the connection between mobility, stability and recovery, it becomes easier to choose the right interventions in time.
