Ehlers-Danlos Syndrome

Other

Overview

Ehlers-Danlos Syndrome (EDS) is a group of inherited connective tissue disorders characterized by defective collagen synthesis, resulting in joint hypermobility, skin hyperextensibility, and tissue fragility. The condition presents with variable severity depending on the specific EDS type, with classical, hypermobility, and vascular subtypes being most common. Osteopathic management focuses on stabilization, pain reduction, and prevention of secondary complications through gentle, tissue-protective techniques.

Pathophysiology

EDS results from genetic mutations affecting collagen synthesis, crosslinking, or structure, compromising the integrity of connective tissues throughout the body. Defective collagen weakens joint capsules, ligaments, tendons, and blood vessel walls, leading to excessive joint laxity, proprioceptive deficits, and vascular fragility. The hypermobility and microtrauma from repetitive instability cause chronic inflammation, pain, and progressive degenerative changes. Secondary issues include poor proprioception, muscle weakness from avoidance patterns, autonomic dysfunction, and gastrointestinal dysmotility.

Typical Presentation

Site

Polyarticular involvement: fingers, wrists, shoulders, hips, knees, ankles; variable spine involvement; often generalized

Quality

Aching, throbbing, burning pain; instability sensations; joint 'slipping' or subluxation feelings; tissue fragility concerns

Intensity

Mild to severe, often disproportionate to clinical findings; fluctuating based on activity and stress

Aggravating

Repetitive movements, prolonged fixed postures, heavy lifting, high-impact activities, sudden position changes, overuse, fatigue, stress

Relieving

Rest, gentle movement, compression, heat, proprioceptive support, pacing activities, relaxation techniques

Associated

Skin hyperextensibility, easy bruising, poor wound healing, fatigue, headaches, vertigo, proprioceptive deficits, muscle weakness, anxiety regarding injury, functional limitation, gastrointestinal symptoms

Orthopaedic Tests

Test descriptions are written with AI assistance from standard clinical texts. Where a test lists Sources, its description has been checked against them; those sources are independent and do not endorse OsteoKit. Accuracy figures and grades (A–D) appear only when checked against the published study; tests without one are marked “No accuracy study”.

Beighton Score

Procedure

Score 1 point for each side: little finger bends back beyond 90° at the knuckle; thumb can be pulled down to touch the forearm; elbow straightens more than 10° past neutral; knee straightens more than 10° past neutral. Score 1 point for placing the palms flat on the floor with the knees straight. Maximum 9.

Positive Finding

A score at or above the age-based cut-off in the 2017 criteria.

Interpretation

Identifies generalised joint hypermobility, which is one part of the criteria for hypermobile EDS; EDS also needs systemic features, family history or a confirmed genetic type. Many people with hypermobility have no disorder. The Beighton score is itself the standard used to define generalised joint hypermobility in the 2017 international criteria (Malfait et al.), so it has no separate accuracy figure. Adults up to 50 usually need 5 or more of 9; from 50, 4 or more. Generalised hypermobility on its own is common and is not a diagnosis. Some EDS types (for example vascular EDS) may have little or no joint hypermobility.

Skin Hyperextensibility Test

Procedure

Gently pinch and lift the skin on the inner forearm or the back of the hand, and watch how far it stretches and how quickly it springs back.

Positive Finding

Skin that stretches further than usual and springs back normally; or soft, velvety, thin or see-through skin.

Reference: Castori et al., 2017, American Journal of Medical Genetics

Interpretation

Very stretchy skin with fragile skin and wide scars suggests classical EDS rather than hypermobile EDS. Thin, see-through skin with visible veins, very easy bruising, or a family history of sudden death or artery or bowel rupture suggests vascular EDS: avoid high-velocity thrust techniques and refer for medical and genetic assessment.

Joint Instability History (Dislocations and Subluxations)

Procedure

Ask about joints that dislocate or partly dislocate (sublux), give way, or need to be put back in, and which joints, how often and how they happened. Check range at the symptomatic joints.

Positive Finding

Recurrent dislocations or subluxations, especially without significant injury.

Reference: Castori et al., 2017, American Journal of Medical Genetics

Interpretation

Recurrent instability is one of the musculoskeletal features in the 2017 criteria for hypermobile EDS. It is not the five-part questionnaire (5PQ), which is a separate self-report screen. Rehabilitation focuses on strength and control rather than end-range stretching.

No accuracy study

Skin Fragility and Bruising History

Procedure

Ask about easy bruising, slow wound healing, wide or paper-thin scars, and wound breakdown after surgery. Inspect scars and bruises.

Positive Finding

Easy bruising, slow healing, or wide, thin, atrophic scars.

Reference: Castori et al., 2017, American Journal of Medical Genetics

Interpretation

Supports a connective tissue disorder and helps separate EDS types. Thin, see-through skin with visible veins, very easy bruising, or a family history of sudden death or artery or bowel rupture suggests vascular EDS: avoid high-velocity thrust techniques and refer for medical and genetic assessment.

Balance and Joint Position Sense Testing

Procedure

Test single-leg stance and heel-to-toe (tandem) stance with eyes open and closed. For joint position sense, move a joint passively with the patient's eyes closed and ask them to copy the position with the same or opposite limb.

Positive Finding

Poor balance or poor accuracy at copying joint position compared with what you would expect for age.

Interpretation

Reduced balance and joint position sense are common in hypermobility and guide rehabilitation. They do not help diagnose EDS. Sudden balance loss with other neurological signs needs medical review.

Moving Patellar Apprehension Test

Procedure

Patient supine, knee straight and relaxed. Part 1: push the kneecap outwards with your thumb, then bend the knee to 90° and straighten it again while keeping the push on. Part 2: repeat the bend and straighten while pushing the kneecap inwards instead.

Positive Finding

Part 1 brings on apprehension (the patient says so or tightens the quadriceps), while part 2 does not: the patient lets the knee bend and straighten freely.

Interpretation

Suggests patellar instability, which is common with generalised hypermobility. Ask about previous dislocations. Rehabilitation focuses on quadriceps and hip strength and control.

⚠ Red Flags

  • •Vascular EDS signs (arterial rupture risk, unexplained hemorrhage)
  • •Acute severe chest or abdominal pain suggesting visceral involvement
  • •Signs of spinal cord compression or myelopathy
  • •Recurrent or spontaneous joint dislocations with neurological compromise
  • •Unexplained syncope or severe autonomic symptoms
  • •Severe anemia from chronic bleeding
  • •Acute eye pain or vision changes (ocular fragility)

⚡ Yellow Flags

  • •Health anxiety and fear-avoidance behaviors regarding movement and injury
  • •Catastrophizing about disease progression and complications
  • •Social isolation due to functional limitations and visible skin changes
  • •Psychological distress from unpredictable pain and symptom fluctuation
  • •Overprotective family dynamics limiting activity and independence
  • •Mood disorders (depression, anxiety) common in chronic EDS
  • •Frustration with previous healthcare provider dismissal or disbelief
  • •Nocebo expectations regarding tissue fragility and treatment risk

Osteopathic Techniques

Physical and occupational therapy are the cornerstones of care: targeted exercise for strength, joint stability and proprioception, with bracing where needed, though trial evidence is limited. A 2024 scoping review found exercise and motor-function training effective in hEDS and HSD, but only weak evidence for manual therapy.

Safety: Check the EDS type first. Vascular EDS carries a risk of arterial and organ rupture: a history of aneurysm, dissection, spontaneous pneumothorax, bowel perforation or unexplained severe bruising raises concern and needs medical review.

Region

Muscles around the spine and painful joints

Technique

Soft tissue, general (affected muscle group)
Grade D
Low evidence: expert consensus or could not be verified against literature
No trials of this technique on its own in hypermobility. A 2024 scoping review found only weak evidence for manual therapy; exercise and motor training had the best evidence.

Rationale

Soft tissue to the painful muscle group, kept within comfort.

How it's done & evidence

How it's done

Hands-on soft-tissue manipulation of the affected muscle group: kneading, stroking, stretching and sustained pressure, with the area relaxed and supported. Use this entry when a card names no body region; regional entries describe the same work for one area.

Evidence in Ehlers-Danlos Syndrome

Searched 27 Oct 2026: no trials of this technique on its own in hypermobility spectrum disorder or hypermobile EDS. Brittain 2024 (scoping review, 28 studies, 630 participants): therapeutic exercise and motor-function training were effective; evidence for manual therapy, adaptive equipment, patient instruction and functional training was weak.

Region

Proximal stabilisers (scapulae, pelvis, trunk)

Technique

Muscle energy, general (affected muscle)
Grade D
Low evidence: expert consensus or could not be verified against literature
No trials of this technique on its own in hypermobility. A 2024 scoping review found only weak evidence for manual therapy; exercise and motor training had the best evidence.

Rationale

Muscle energy technique to ease and lengthen the affected muscle.

How it's done, cautions & evidence

How it's done

The muscle is taken to its barrier. The patient pushes gently, at about 10–20% effort, against resistance for 5–10 seconds, relaxes for 3–5 seconds, and the new barrier is taken up.

Cautions

Not used with an acute fracture, a joint infection or a bone malignancy; take care with severe osteoporosis or after surgery that limits muscle contraction. Use the least force needed: too much can tear a muscle or pull off a tendon, especially in older patients.

Region

Painful hypermobile joints (held in ease)

Technique

Facilitated positional release (FPR)No trials found

Rationale

Facilitated positional release: a gentle, indirect technique held in a position of ease, with no stretch into end range.

How it's done, cautions & evidence

How it's done

An indirect technique related to counterstrain, diagnosed by 3-plane motion findings rather than tender points. Bring the area to neutral, then into its position of ease. Add an activating force (compression, torsion or traction) and hold for about 5 seconds, then return to neutral and re-check.

Cautions

Do not use over an acute fracture, or in a patient who cannot give feedback.

Evidence in Ehlers-Danlos Syndrome

Searched 27 Oct 2026: no trials of positional release in Ehlers-Danlos syndrome.
