Hypermobility spectrum disorder (HSD)

Much of the practical discussion in patient communities is about joints that partly slip out of place (subluxation) rather than fully dislocate. Members swap taping, bracing, and stabilizing techniques, often for subluxations no doctor has confirmed.

hEDS, HSD, cEDS · Community knowledge

Members treat finding a physical therapist as a search problem. They share directories and word-of-mouth referrals and look for therapists who avoid the generic exercise programs members consider harmful.

hEDS, HSD · Community knowledge

Members share advice on which specialists diagnose EDS, which tests matter, and how to prepare for an appointment, in response to diagnostic delays that often last years. This is peer advice, not a clinical pathway.

hEDS, HSD · Community knowledge

Patient communities often describe hEDS, POTS (a form of dysautonomia), and mast cell activation syndrome (MCAS) occurring together, and call the combination the “trifecta”. In a Global Registry survey of 505 people with hEDS, POTS and MCAS were among the diagnoses participants most often endorsed as accurate. Whether the three share a mechanism is unknown.

hEDS, HSD · Comorbidities and systemic features

Tinkle and colleagues describe digestive and autonomic problems among the conditions reported with hEDS in their 2017 review. Autonomic problems affect functions such as heart rate and blood pressure. In Rauterberg and colleagues’ 2025 German clinic survey, 31 of 80 respondents with hEDS or HSD reported digestive complaints severely affecting daily activities (38.8%), and 25 of 80 reported autonomic complaints at that level (31.3%). Respondents could report both kinds of complaint.

hEDS, HSD · Comorbidities and systemic features

hEDS diagnosis under the 2017 International Classification requires (1) generalized joint hypermobility by Beighton score, (2) at least two of three feature groups: systemic manifestations, a positive family history, and musculoskeletal complications, and (3) exclusion of other connective-tissue disorders. Unlike every other subtype, hEDS has no molecular confirmation test.

hEDS, HSD · 2017-03 · Diagnosis and classification

The 2017 framework (Castori et al.) separated symptomatic joint hypermobility into hEDS when the strict criteria are met and HSD when they are not. The boundary is contested. The criteria were designed to define a more uniform group for research, not to declare HSD benign.

HSD, hEDS · 2017-03 · Diagnosis and classification

HEDGE (Hypermobile Ehlers-Danlos Genetic Evaluation), listed among The Ehlers-Danlos Society's research programs, is studying the genetics of 1,000 people with hEDS. In October 2025 the society said it expected the first publications in late 2025 or early 2026, and that timelines may shift.

hEDS, HSD · Genetics

Clinical guidance gives individualized physical therapy (strengthening, proprioceptive work, and pacing) a central role in managing hEDS and HSD. A 2017 paper on physical therapy by Engelbert and colleagues says the research on managing these conditions is limited in size and quality, so the advice rests more on expert consensus and clinical experience than on large trials.

hEDS, HSD · Management and clinical care

Studies of the diagnostic journey in hEDS describe medical gaslighting and post-traumatic stress, and management guidance includes psychological support. A 2025 qualitative study of people with hEDS says physicians should be aware of possible medical post-traumatic stress disorder and highlights the importance of trauma-informed care.

hEDS, HSD · 2025 · Management and clinical care

A qualitative study of people diagnosed with hEDS, published in BMJ Connections Clinical Genetics and Genomics in December 2025, found that experiences with providers ranged from harmful dismissal to validation, and that a diagnosis brought both validation and grief. The authors say physicians who diagnose and treat hEDS should be aware of possible medical post-traumatic stress disorder and past experiences of medical gaslighting. In a separate Global Registry survey of people with hEDS, anxiety and depression were among the most common other diagnoses they had received.

hEDS, HSD · 2025 · Patient experience and diagnostic odyssey

Rauterberg and colleagues found that pain was the complaint most often reported to severely affect daily activities at a German EDS clinic. Their 2025 paper surveyed 99 adults attending University Hospital Cologne, including 80 with hEDS or HSD, 16 with classical EDS, and three with classical-like EDS. Of the 98 who answered the daily-activity question, 59 reported musculoskeletal pain (60.2%), 38 joint instability (38.8%), 36 other orthopedic problems (36.7%), 35 digestive complaints (35.7%), and 32 fatigue (32.7%). Respondents could name more than one complaint. These figures describe one specialist clinic.

Rauterberg and colleagues found that 32 of 98 adults at a German EDS clinic reported fatigue severely affecting daily activities (32.7%). The 2025 study included people with hEDS, HSD, classical EDS, and classical-like EDS. Within the hEDS/HSD group, 27 of 80 respondents reported this level of fatigue (33.8%). Fatigue is not one of the 2017 hEDS diagnostic criteria.
