Part 2 of Joint Hyermobility Syndrome (Part 1 is lower down in my feed). These articles are compliments of an amazing Sports Therapist in the UK, Em Stuart who I have so much respect for.
Joint Hypermobility Syndrome Part 2
As previously mentioned, this condition is more commonly seen in females, but it’s also more common in non-Caucasian populations, particularly Asian and Afro-Caribbean populations.
Joints hypermobility syndrome (JHS) and Ehlers Danlos Syndrome (EDS) have a genetic link, however, they do not have any known genetic markers, so there is no blood test that can be done to confirm its presence.
What is predominantly affected is collagen and elastin that make up our body, affecting not only the skin but the fascia, muscles, bone, ligaments, tendons, joint capsules, cartilage, our spinal discs and also the brain. So basically, abnormal collagen.
How does Hypermobility affect the brain?
Anxiety and JHS and EDS have a long-established history together but links to ADHD and autism are well documented in literature, this also explains why JHS sufferers experience altered sensation.
A large proportion of people with JHS (over 70%) have psychological symptoms including panic disorders, anxiety, and depression.
Eating disorders
Studies that look at eating disorders have found that high proportion of participants have JHS. This is true of ARFID (avoidance restricted food intake disorder) and other forms of eating disorders including, but not limited to, Anorexia Nervosa.
Some studies have reported that 41% of participants with eating disorders had JHS which is a much higher percentage that the population that have been diagnosed with JHS (approximately 3% but other studies suggest it’s as high as 10% of the population). There appears to be a gut-brain interaction dysfunction. Some of my clients report that they have slow transit of food and consequently, reduced oral intake. This can be difficulty swallowing, vomiting, low grade constant nausea (a common symptom in POTS), indigestion, bloating, irritable bowel syndrome and altered oesophageal and/or gut motility (slow transit of food). Oesophageal hypersensitivity is also more common in people with hypermobility.
Functional neurological disorder (FND)
FND is when the brain does not work as designed which can lead to symptoms such as difficulties in movement, seizures, memory loss/cognitive issues; speech, vision or heating issues, chronic pain, fatigue and sensation issue (numbness) to name but a few.
Some of my hypermobile clientele have, or are being investigated for, functional neurological disorder. Its is believed hypermobility, anxiety and depression all contribute to FND.
How does Hypermobility affect the nerves?
Restless leg syndrome, I have at least ten hypermobile clients with this condition, and is linked to JHS. Restless leg syndrome is when you just have to move your legs, the urge is irresistible. Due to the extra joint range, nerves are stretched more than normal so neurological pain symptoms are not uncommon.
Mast Cell activation Syndrome (MCAS)
JHS sufferers on occasion also experience MCAS which is condition where the bodies Mast Cells (a form of white blood cell) go into overdrive and release too many chemicals into the bloodstream. Symptoms include.
Heart – Low BP, tachycardia and feinting. Gastrointestinal – abdominal cramping, constipation/diarrhoea, nausea and vomiting. Breathing - Shortness of breath and wheezing. Skin -Itching, rashes, swelling, hives and skin writing. Neurological symptoms - Headaches, fainting, brain fog, balance problems, memory problems, anxiety, depression, mood swings.
These episodes can be triggered by stress, insect bites, temperature changes, foods, medicines, strong chemical odours and exercise.
Blood
Some of my hypermobile clients have, for no reason the medical profession can explain, a high C-reactive protein marker (CrP); these are normally present only when a systemic infection is present, however, in these clients they are consistently high without the presence of infection. I have yet to be able to find out why this happens, only that it does in many cases. If any haematologist wish to enlighten me feel free to comment! I will continue to research however.
Joint and tendon pain & autoimmune links
JHS is also prevalent in rheumatoid arthritis populations and a link has long been recognised. Usually the presence of HLA-B27 (a rhumatoid arthritis marker in the blood) is present, but again several clients lack this marker but still get rheumatoid arthritis like symptoms.
Arthralgia – pain emanating from the joints.
Myalgia – pain emanating from the tendon, ligaments and soft tissue. It can present with or without muscle cramps.
Arthritis – premature osteoarthritis is common with JHS and EDS, as is lower bone mass so earlier presentation of osteopenia (the pre-curser to osteoporosis) and osteoporosis itself.
Tendon issues including bursitis, tendinopathies, and irritation to tendons and their surrounding tissues which include tennis elbow, golfers elbow, De quervains, medial tibial stress syndrome and Achilles irritations.
Disc herniations – Because of the affect on the collagen and its matrix, this makes discs easier to herniate in JHS populations. Those with this are more likely to require a surgical solution.
Coccygeal joint dysfunction – Instability of the coccyx is also prevalent with JHS, suffers experience pain in the coccyx area (the tail bone) of their spines, and symptoms are aggravated by sitting.
Temporomandibular joint (TMJ) pain and dysfunction are a common presentation as well.
Tinnitus – Those with TMJ disorder have a higher likelihood of having tinnitus with it.
Bones
Osteopenia – I had a client back in the early years of my clinic present with a herniated disc. While going through her medical history, she has been diagnosed with osteopenia (the pre-curser to osteoporosis) and degenerative disc disease (DDD) in her 20’s! When she had an MRI her herniated disc was so bad it was labelled a sequestration (Grade IV). Interestingly, no pain medication her GP prescribed affected or lowered her pain. She scored highly on the Beighton scale.
Earlier signs of osteoarthritis (often a decade earlier) and osteopenia (the precursor to osteoporosis) which can be from altered gait and biomechanical dysfunction as well as poorer cartilage quality leading to earlier degeneration.
Lower bone mass, reported in some studies on young adults could account for poor and delayed bone healing in some cases. This is something that can be later exacerbated in perimenopause and menopause.
Gait abnormalities
Flat feet (pes planus), bunions (hallux valgus) and Genu valgus (knock knees) are also more common in JHS sufferers.
B12/Folate levels
One thing that commonly comes up with my JHS clients is low folate and low B12 for no reason that can be explained.
B12 and Folate function together. Folate deficiency links to some types of JHS but the mechanisms are still being explored.
Blood Vessels
Varicose veins – Varicose veins, hernia, or uterine or re**al prolapse are more common in JHS populations.
The Heart
In the last part we explored postural orthostatic tachycardia (PoTS) which effect the heart, but JHS also affects Heart conditions such as mitral valve prolapse are more prevalent as well.
Eyes
Drooping eyelids, Astigmatism and myopia (short sightedness) are more commonly experienced.
Raynaud’s
Raynaud’s is when sufferers experience decreased blood flow to hands and feet. Having white or slightly blueish hands and feet isn’t uncommon. Some of my JHS clients wear thick socks even in summer.
Thyroid links?
Several of my hypermobile clientele have ‘thyroid issues’. There is a link between JHS and thyroid disorders because thyroid function can affect the formation of cellular components and collagen formation.
Despite researching this link and many JHS journals mentioning the role the thyroid plays, I cant quite find the ‘smoking gun’ that gives us a cause and effect but I will continue to search for it in literature.
What can be done to help?
Not to put too fine a point on it but this condition provides both diagnostic and management challenges…
With muscle weakness and sometimes a fear of movement (Kinesiophobia) due to suffering chronic pain, it might be advisable to use hydrotherapy. Not only does the water stabilise the joints but the hydrostatic pressure helps those that may be suffering with POTS (postural orthostatic tachycardia syndrome) due to improved venous return, but warmer water is better tolerated.
Soft tissue therapy can be very helpful in modulating pain in muscles, but care must be taken with regards to mobilisations of the peripheral joints. If I do mobilise a joint, then I treat my clients with caution, often a sustained traction is far better than an oscillating movement and produces less stress on their tissues.
From my experience with my clients all seem to respond well to soft tissue massage, dry needling, PNF stretching, carefully considered joint mobilisation and TECAR therapy. Physical therapy approaches to improve proprioception will help to decrease balance issues and low impact strengthening does work.
From a pain perspective, many journals also suggest cognitive behavioural therapy.
In part 3, I hope to explore pregnancy and post-partum challenges in hypermobile populations.
