Joint hypermobility & hypermobility Ehlers Danlos Syndrome (hEDS) Explained: Symptoms, Diagnosis and Management
Joint hypermobility is common and, for many people, entirely benign. For others, it can be associated with chronic pain, fatigue, joint instability and a significant impact on daily life. Understanding when hypermobility is simply a normal variant and when it becomes clinically relevant is an important part of rheumatology assessment.
Many people with hypermobility present after months or years of unexplained symptoms, often with normal blood tests and scans. Clear explanation, reassurance and a structured approach to management can make a substantial difference.
What Is Joint Hypermobility?
Joint hypermobility refers to joints that move beyond the usual range expected for a given joint. This is typically related to increased elasticity of ligaments and other connective tissues.
Hypermobility is:
relatively common
more frequent in women
often present from childhood
variable over time
For many individuals, hypermobility causes no symptoms at all. In others, it may be associated with pain, fatigue, recurrent soft-tissue strain or a sense of joint instability.
Why Are the Joints More Flexible?
Joint hypermobility is thought to relate to differences in connective tissue, particularly collagen. Collagen is a key structural protein that provides strength and stability to ligaments, tendons and joint capsules.
In people with hypermobility, connective tissues may be more elastic than average. While this allows a greater range of movement, it can reduce passive joint stability, meaning muscles must work harder to support joints. Over time, this increased demand can contribute to pain, fatigue and symptoms of joint “giving way”, particularly during everyday activities.
The Beighton Score: What It Does — and What It Doesn’t Do
The Beighton score is a simple clinical tool used to assess joint hypermobility. It looks at flexibility in a small number of joints and produces a score out of nine.
While the Beighton score can be helpful as a screening tool, it has important limitations. It reflects joint flexibility at a single point in time and does not account for symptoms, pain, function or how joints behave during daily life.
Many adults who were clearly hypermobile in childhood may no longer score highly, as joint flexibility often reduces with age. A low Beighton score therefore does not exclude clinically relevant hypermobility, particularly when there is a supportive history. Symptoms and function are more important than any single numerical score.
Hypermobility and Physical Ability
Joint hypermobility can be advantageous in certain settings. Many people who are hypermobile as children or young adults excel in activities that favour flexibility, such as gymnastics, dance, yoga, swimming or martial arts.
However, the same joint laxity that confers flexibility can also place greater demands on muscles and soft tissues for stability. As training reduces, life circumstances change or injury occurs, symptoms may emerge later in life. This helps explain why pain or fatigue can develop years after a period of high physical ability.
Hypermobility Across the Lifespan
Hypermobility is often most noticeable in childhood and adolescence, when connective tissues are naturally more elastic. Many people become less flexible with age as ligaments stiffen and joint range of motion reduces.
Importantly, reduced flexibility in adulthood does not mean earlier hypermobility is irrelevant. In some individuals, childhood hypermobility may be associated with later widespread musculoskeletal pain, fatigue or reduced physical resilience, even if joints are no longer overtly hypermobile on examination.
Hypermobility, HSD and hEDS
Terminology around hypermobility can be confusing:
Joint hypermobility describes increased joint range of motion alone.
Hypermobility Spectrum Disorder (HSD) refers to hypermobility associated with pain and functional symptoms.
Hypermobile Ehlers–Danlos syndrome (hEDS) is a specific inherited connective tissue disorder with defined diagnostic criteria and additional clinical features.
Most people with symptomatic hypermobility do not have hEDS. Careful clinical assessment is far more important than assigning labels.
Is Hypermobility Genetic? Do I Need Genetic Testing?
Joint hypermobility often runs in families, suggesting a genetic contribution. However, for most people with hypermobility or HSD, there is no single identifiable genetic test, and genetic testing is not routinely required.
Specific inherited connective tissue disorders are uncommon and usually associated with additional clinical features. In the majority of cases, clinical assessment is more informative than extensive investigations.
Associated Features Sometimes Seen with Hypermobility
Some people with hypermobility report additional features such as easy bruising, cold sensitivity of the fingers or toes (including Raynaud’s phenomenon), or symptoms related to circulation or temperature regulation.
These features are not specific to hypermobility and are common in the general population. When they occur alongside hypermobility, they are usually mild and do not imply serious underlying disease. Context and overall clinical assessment are key.
Why Blood Tests and Scans Are Often Normal
Hypermobility-related symptoms are usually non-inflammatory. As a result:
inflammatory markers such as ESR and CRP are typically normal
autoimmune blood tests are usually negative
imaging may not show joint damage
This does not mean symptoms are “not real”. It reflects a different mechanism of pain related to joint mechanics, muscle control and connective tissue properties rather than inflammation.

Pain Management in Hypermobility
Pain associated with hypermobility is usually mechanical rather than inflammatory. It often reflects a combination of joint instability, muscle overuse, altered movement patterns and, in some cases, heightened pain sensitivity over time.
Pain management works best when it is multimodal:
targeted strengthening and stability-focused physiotherapy
pacing activity to avoid boom-and-bust cycles
addressing sleep disturbance and fatigue
simple analgesia where appropriate
Anti-inflammatory medications are often of limited benefit unless there is a co-existing inflammatory condition. The aim of management is not necessarily to eliminate pain entirely, but to improve function, confidence and quality of life.

Exercise and Physical Resilience
Exercise is a key part of managing hypermobility, but the focus is on strength and control rather than flexibility. Well-structured, low-impact programmes help improve joint stability and reduce symptom flare.
Guidance on safe, sustainable activity can be found in Exercise in Rheumatic Disease: A Practical Guide.
Management and Long-Term Outlook
There is no single medication that treats hypermobility itself. Management focuses on:
improving joint stability
supporting physical resilience
reducing symptom impact
building confidence in movement
Hypermobility does not inevitably worsen over time. With understanding, appropriate exercise and realistic expectations, many people experience meaningful improvement.
In Summary
Joint hypermobility is common and often benign
In some people, it is associated with pain, fatigue and instability
Childhood hypermobility may remain relevant in adulthood
Blood tests and scans are usually normal
Genetic testing is not routinely required
Management focuses on strength, stability and whole-person care
With appropriate support, long-term outcomes are often good
