Synopsis
Assess symptomatic joint hypermobility systematically, distinguish hypermobile Ehlers-Danlos syndrome from hypermobility spectrum disorder and monogenic EDS subtypes, recognise vascular danger, and coordinate stabilising rehabilitation, symptom care, genetics and reproductive planning.
- Joint hypermobility is a physical trait; HSD or hEDS requires symptoms or associated features after exclusion of another explanation, and neither follows from flexibility alone.
- Score Beighton manoeuvres correctly: the 2017 hEDS threshold is at least 5 of 9 from puberty through age 50 and at least 4 after 50; historical questions help when one point below.
- All hEDS groups are required: generalised hypermobility; at least two of Feature A with five systemic findings, Feature B with an independently affected first-degree relative, or Feature C with qualifying pain or instability; and complete exclusions.
- There is no confirmatory genetic test for hEDS; molecular testing is directed by features of vascular, classical or another monogenic subtype, not ordered as a generic hypermobility panel.
- HSD can be as functionally important as hEDS; management is based on instability, pain, fatigue and comorbidity rather than perceived label rank.
- Use progressive proprioceptive, strength and movement-control rehabilitation, pacing, task adaptation and selected braces; aggressive stretching or prolonged immobilisation can worsen stability and deconditioning.
- Sudden severe chest, abdominal, head or limb pain in suspected vascular EDS is an emergency; state the diagnosis because imaging, access and operative strategy require tissue-fragility expertise.
- Pregnancy planning should identify subtype where possible; vascular EDS needs genetics and maternal medicine, while hEDS or HSD benefits from pelvic-health and anaesthetic planning.
Key red flags
Arterial rupture or dissection, spontaneous bowel perforation, uterine rupture, pneumothorax or unexplained sudden death in a young first-degree relative raises vascular EDS and warrants specialist genetics assessment.
Marked skin fragility with broad atrophic scars, easy tearing, congenital hip dislocation, severe progressive scoliosis, ocular rupture or early periodontal loss suggests a monogenic subtype.
A hot swollen joint after a procedure or injury, fever, severe unremitting bone pain or progressive neurological loss requires an infection, fracture or compression pathway.
Syncope during exertion, chest pain, sustained tachyarrhythmia or focal neurological events must not be assumed to be benign dysautonomia without acute assessment.
Investigation priorities
Confirm current and historical hypermobility, document functional consequences and detect signs requiring another route.
Management branches
Recurrent pain, instability or systemic connective-tissue features accompany current or historical hypermobility.
- Measure Beighton score correctly, document non-Beighton and historical mobility, and establish whether symptoms are plausibly related rather than incidental.
- Apply all hEDS criteria groups, examining systemic features and excluding inflammatory, neuromuscular, skeletal and alternative heritable disorders.
- Diagnose HSD when symptomatic hypermobility remains important but hEDS and another defined disorder are not met, explaining that treatment need is not label-dependent.
- Refer to clinical genetics when vascular, classical, ocular, skeletal or other distinctive fragility makes a molecular subtype plausible.
Instability, pain, fatigue or movement fear limits function without fracture, unreduced dislocation or emergency.
- Begin proprioception, neutral-position awareness, low-load closed-chain strength and movement quality, progressing repetitions, resistance and complexity gradually.
- Use pacing and aerobic conditioning to reduce boom-and-bust activity while avoiding repeated end-range demonstrations and aggressive stretching.
- Add occupational adaptation, footwear, tape or task-specific brace when it improves function, and maintain active muscle support rather than permanent immobilisation.
