Table 2 describes the characteristics of the 32 included studies. The majority of studies were conducted in either the UK or United States of America (USA) ( n = 6, 19%), followed by France ( n = 4, 13%) and were mostly case–control ( n = 10, 31%) or cross-sectional ( n = 8, 25%) in design. The sample size ranged from a total of 1 to 2404, with the majority ( n = 31, 97%) having a predominantly female sample and a mean age range of 20–68.5 years ( SD = 5.71–13.9).

All studies included samples with a clinical diagnosis of either EDS (inclusive of sub-types) or HSD [e.g., joint hypermobility syndrome (JHS)] as diagnosed by an appropriate clinician or validated tool. Diagnosis was mostly done by rheumatologists [ 17 ], geneticists [ 17 ], national experts in EDS [ 18 ] or primary care practitioners [ 19 ], with referrals to mental health professionals not uncommon though viewed as dismissive by individuals [ 20 ]. The Beighton Scoring System ( n = 10, 31%) and Brighton Diagnostic criteria ( n = 9, 28%) were most frequently used as the validated tool to support a diagnosis of joint hypermobility whilst a more recently revised diagnostic criteria for EDS was less frequently utilised ( n = 3, 9%) [ 17 , 21 , 22 ].
In this review, 31 (97%) of the included studies referred to physical manifestations whilst 29 (91%) studies referred to psychological manifestations. These manifestations were found to be either directly related to the EDS/HSD e.g., dysautonomia, or otherwise highly prevalent and clinically significant within this population e.g., anxiety and depression. Weak associations and less frequently reported symptoms and conditions have also been documented within this review for completeness. The social impact is referred to throughout the included studies (e.g., impact on QoL), more so in the qualitative studies where individuals had the opportunity to detail their lived experiences and diagnostic odyssey. The symptoms and conditions have been categorised by speciality sub-headings with Tables 3 and 4 , and Fig. 2 providing more details. Table 3 Biopsychosocial impact and study findings Author (year) Physical Psychological Social Findings Palomo-Toucedo, et al. (2020) [ 6 ] Miscellaneous: pain, physical fatigue, exhaustion Negative affect: exhaustion, misunderstood Miscellaneous: pain, fatigue Employment: professional life Hobbies/daily activities: physical activity limited Lifestyle: restriction on daily routines, atmospheric changes Social relationships: social isolation behaviours, misunderstanding, social image, short term social plans, social relationships, sexual sphere, support groups/sharing, emotional support; EDS affects daily life, in a physical level and a psychological and social sense. Social support is important. Patients need to be aware of the changes in their social life because of the disease so that they can have a better QoL. Progression of symptoms reduce employment opportunities, causing economic restrictions and diminish their self-care. HCPs need to know this information to provide better care and improve their QoL Hershenfeld, et al. (2016) [ 9 ] Cardiology Dermatology: skin hyperextensibility, abnormal scarring, striae Gastroenterology: abdominal pain, functional bowel disorders Haematology MSK/Orthopaedics: joint pain, inflammation, hypermobility, dislocations and subluxation, muscle pain Neurology: neuropathic pain, headaches, migraines Miscellaneous: pain symptoms, fatigue Anxiety disorders (23.6%): PTSD (4.7%) Behavioural disorders: ADHD (6.6%), conduct disorder (1.9%) Developmental disorder: Asperger disorder (0.9%) Eating disorders: AN (1.9%) Learning difficulties (1.9%) Mood disorder: depression (42.5%), bipolar disorder (1.9%); Personality disorder: BPD (3.8%), schizotypal disorder (0.9%) Psychosis: schizoaffective disorder (0.9%) Miscellaneous: fatigue NS High frequency of psychiatric disorders (e.g., depression and anxiety disorders). Pain symptoms are significantly associated with having a psychiatric disorder. Need to screen for mental health disorders in EDS patients, especially with pain symptoms. Need to support the recognition of psychiatric disorders within EDS. Many are stigmatised and dismissed without further investigation, contributing to delays in a diagnosis of EDS. Awareness will better address, manage and improve QoL Alomari, et al. (2020) [ 16 ] ANS/Cardiology: PoTS (39.9%) Gastroenterology: GI dysmotility: oesophageal dysmotility (23.8%), gastroparesis (42.8%), small bowel/colon altered transit time (11.9%), global dysmotility (9.5%) GI manifestations: abdominal pain (49.8%), nausea (49.5%), constipation (45.4%), diarrhoea (37.6%), IBS (28%), IBS subtypes (D—4.1%, C—2.3%, M—2.8%, U—12.4%) bloating/belching (27.1%), vomiting (26.1%), dysphagia (14.2%), faecal incontinence (6%), heartburn (35.8%), pelvic floor dysfunction (33.9%), faecal urgency (3.7%), rectal prolapse (1.8%), GORD (37.6%), oropharyngeal dysphagia (1.4%) Rheumatology: fibromyalgia (35.8%) Anxiety disorder: GAD (29.4%) Behavioural disorder: ADHD (11%) Mood disorder: depression (33%), bipolar disorder (6%) NS GI dysmotility in hEDS is not uncommon and underdiagnosed. PoTS was an independent predictive factor for GI dysmotility in hEDS. Need to improve outcomes and quality of care Baeza-Velasco, et al. (2018) [ 17 ] Miscellaneous: mild/moderate pain (32.5%), severe/very severe pain (66.25%), mild/moderate fatigue (31.25%), severe/very severe fatigue (68.75%) Anxiety disorder: anxiety Cognitive: pain catastrophising Mood disorder: high depressive symptomatology (18.75%) Negative affect: fear of pain and movement Miscellaneous: somatosensory amplification Social relationships: social functioning, social support Important to consider the psychosocial factors–this will improve adjustment to this chronic condition and provide support to those affected via a biopsychosocial approach Murray, et al. (2013) [ 18 ] Cardiology (96%): tachycardia, palpitations Dermatology (95%): skin hyperextensibility, problems with scarring, smooth/velvety skin, easy bruising Gastroenterology (96%): rectal prolapse, IBS, GERD, diarrhoea, nausea, constipation Gynaecology/Urology (67%): uterine prolapse, bladder prolapse, infertility, endometriosis, vulvodynia MSK/Orthopaedics (99%): locked jaw, scoliosis, flat feet, arthritis, TMJD, joint dislocations, subluxations and pain, limb pain, hypermobility Neurology (88%): restless leg syndrome, hypersomnia, nerve compression, other headache, tension headache, migraine headache, dizziness Rheumatology: fibromyalgia Miscellaneous: chronic/constant pain (67%), tiring/exhausting pain (93%), aching (80%), chronic fatigue (92%), insomnia Anxiety disorder: anxiety (73%) Mood disorder: depression (69%) QoL Miscellaneous: insomnia, chronic fatigue, dizziness, chronic/constant pain (67%), tiring/exhausting pain (93%), aching (80%), chronic fatigue (92%) Education: unable to enrol full time Employment: change roles, less responsibility QoL Documenting of the broad array of symptoms, clinical diagnoses and effects on QoL has important implications for HCPs. Supports the need for better recognition, understanding, and management as a multisystemic, disabling condition and a multidisciplinary approach to management is necessary Halverson, et al. (2021) [ 19 ] ANS/Cardiology: dysautonomia, PoTS (63.6%) Dermatology: rashes Endocrinology: Cushing syndrome (4.5%) Gastroenterology: vomiting, CVS (13.6%), gastroparesis (13.6%), ulcerative colitis (9.1%), IBS (4.5%) Gynaecology: endometriosis (9.1%), pelvic floor dysfunction (22.7%), PCOS Immunology: MCAS (40.9%) Infectious diseases: Epstein Barr (13.6%), Lyme disease (9.1%), meningitis (9.1%) MSK/Orthopaedics: hyperextending (arms and legs), extraordinary flexibility, chronic knee pain, stiffness, cervical instability (31.8%), carpal tunnel syndrome, scoliosis (13.6%) Neurology: recurrent headaches, neurosyncope, cognitive fogs, fainting, headaches, meningitis (9.1%), MS (22.7%), intercranial hypertensions (4.5%) Oncology: paraneoplastic syndrome (4.5%) Ophthalmology: glaucoma (4.5%) Respiratory: respiratory dystonia, stridor Rheumatology: fibromyalgia (40.9%), lupus (13.6%), Raynaud’s disease (9.1%) Miscellaneous: pain, fatigue, unbearable pain, chronic pain, iatrogenic physical harms, CRPS (9.1%), chronic fatigue (27.3%), tethered cord (9.1%), cerebellar tonsillar ectopia (4.5%), cytomegalovirus (4.5%), failed neck syndrome (4.5%), lordosis (4.5%), tendonitis (4.5%) Anxiety disorder: anxiety (54.5%) Cognitive: cognitive fogs, distress, exhausting, self-regulation (spoon theory), self-doubt, lonely, depressed, worthlessness, self-hate Learning difficulty: dyslexia (4.5%) Mood disorder: depression (68.2%), bipolar disorder (9.1%) Negative affect: frustration, burdensome (symptoms), overwhelming (symptoms), distress; Suicidal ideation: suicidal thoughts Miscellaneous: CRPS (9.1%), chronic fatigue (27.3%), pain, fatigue, iatrogenic physical harms Education: high school/college dropout Employment: did not pursue careers Healthcare experiences: encountered lack of understanding, encountered lack of empathy, dismissive treatment by healthcare professionals, distrust of medical providers, incomplete diagnoses, aversion to hostile clinical environments Hobbies/daily activities: abandoned hobbies/athletic pursuits due to physical limitations, daily activity limitations Social relationships: creeping isolation, lost entire social groups, lost support of loved ones, unable to participate in activities, relationships atrophied, lonely, social networks crumbling; Specific, difficult struggles faced, cases are complex. Long, overwhelming struggles of the diagnostic odyssey explains where and how these tensions arise. The journey is both limited and limiting. A significant misconception to think of these patients as difficult. Extraordinary lengths to find a medically valid explanation. Encounters are made difficult by the burden of this long and tumultuous odyssey. Need for greater empathy in the patient–provider relationship Maya, et al. (2021) [ 20 ] ANS/Cardiology: dysautonomia (70%); postural symptoms (62%); palpitations (53.5%), chest pain/discomfort (33.7%), hypotension (10.9%), exercise intolerance (78%), true/near syncope (37.6%), LE oedema (14.9%) Gastroenterology (61.4%) Respiratory: dyspnoea (35.6%), chest pain/discomfort (33.7%) Urology (8.9%) Neurology: dizziness (70.3%), poor concentration (46.5%) Miscellaneous: Fatigue (77.2%), thermodys regulation (33.7%), pain (50%) Miscellaneous: fatigue (77.2%), pain (50%), palpitations (53.5%) Lifestyle: sedentary lifestyle (> 75%) Having hEDS/HSD or dysautonomia are at risk for substantial morbidity and impaired QoL. Having both hEDS/HSD and dysautonomia imposes a greater symptomatic burden and disproportionately affects young women. hEDS/HSD leads to exercise intolerance, avoidance and a sedentary lifestyle Wasim, et al. (2019) [ 21 ] Cardiology (41.2%) Dermatology (60.6%): skin hyperextensibility Gastroenterology (61.6%) Haematology (63.2%) MSK/Orthopaedics (96.9%): joint hypermobility, recurrent joint dislocations Neurology (54.5%) Ophthalmology (46.3%) Rheumatology: rheumatoid arthritis, systemic lupus erythematosus Urogenital (24%) Miscellaneous: pain (85.7%) Anxiety disorder (28.6%) Behavioural disorder (11.5%): ADHD (4.6%) Learning difficulty: dyslexia/speech difficulties (2.8%), self-harm/suicide (0.5%) Mood disorder (34.5%): depression (30.2%), bipolar disorder (1.9%) Personality disorder: schizotypal disorder (0.3%) Psychosis: schizoaffective disorder (0.3%) NS Mood and somatoform disorders were associated with pain and GI dysfunction. ADHD was more frequent in HSD. Psychiatric findings and systemic associations were similar across the spectrum of HSD/EDS, management should be similar regardless of diagnosis. Importance of screening for mental health disorders in HSD/EDS, particularly those with pain and GI symptoms. Awareness of the associations will aid management and identify those at a higher risk for mental health disorders Saetre & Eik (2019) [ 22 ] MSK/Orthopaedics: hypermobile (body capable of unlimited movement), pain as children (dismissed as growth pain), decreased function, bodily disruption, bodily discomfort, body feels loose, body failure, sudden falls, imbalance of body tolerance, range of flexibility Miscellaneous: fatigue, feeling a lack of energy, sleep disturbances Negative affect: frustration (perceived lack of knowledge and understanding), feeling a lack of energy, overwhelming, anger, grief, distress, fear, hope and hopelessness, uncertainty, disharmony Hobbies/daily activities: daily activities, lack of energy for activities, exercise-daily activity imbalance, restrictions Complex experiences of having flexible bodies and restricted lives. Pain, fatigue and weakness demand attention and resolution, causing individual suffering. HCPs need to develop an ethical attitude and sensitivity in listening, and acknowledge bodily experiences to understand the nature of this illness An integrated approach in the management may provide a deeper understanding, better clinical decision‐making and improved possibilities for recovery Terry, et al. (2015) [ 23 ] MSK/Orthopaedics: recurring joint dislocation Miscellaneous: fatigue, pain (chronic and acute), proprioception Anxiety disorder: heightened anxiety Cognitive disorder: catastrophising Negative affect: modify/restrict behaviours, stigmatised, fraudulent Miscellaneous: fatigue, pain Hobbies/daily activities: modify/restrict behaviours, activity pacing Diverse, fluctuating and debilitating symptoms. Diagnosis is slow, exacerbating symptoms. Increased awareness in primary care could help improve the diagnosis and referral processes. Access to JHS-trained professionals could help patients to effectively manage their condition and receive psychological support as needed. Patients and professionals should learn from one another and assist in developing a deeper understanding of a poorly understood condition Mullick, et al. (2013) [ 24 ] Dermatology: skin laxity (1.2%) MSK/Orthopaedics: excessive joint clicking and laxity (25%), recurrent joint dislocations (8.33%), carpal tunnel syndrome (1.2%), knee pain (51.2%), low backache (23.8%) Rheumatology: non-specific polyarthralgia (52.38%), soft tissue rheumatism (13.1%), fibromyalgia (4.76%), synovitis (4.76%) Miscellaneous: lateral head tilt (10.71%) Anxiety disorder (1.2%) NS Under-recognised and usually missed in clinical practice due to a lack of awareness. Need to consider even when presenting with non-specific MSK symptoms. The ‘lateral head tilt sign’ was an incidental finding in 10%, could be a leading clue Martinez, et al. (2021) [ 25 ] ANS/Cardiology: dysautonomia, mitral valve prolapse (0% vs 3.6% vs 25.5%), aortic root dilation (0% vs 0% vs 6.1%) Dermatology: unusually soft or velvety skin (27.3% vs 67.9% vs 79.6%), mild hyperextensibility skin (31.8% vs 50% vs 51%), unexplained striae (27.3% vs 28.6% vs 59.2%), bilateral piezogenic papules (36.4% vs 39.3% vs 73.5%), atrophic scarring (13.6% vs 35.7% vs 55.1%) Gastroenterology: lump in throat, difficulty swallowing, nausea, vomiting, chest pain, intolerance of several foods, abdominal fullness, abdominal bloating, feeling of abdominal distension, abdominal pain, bowel noises, stools very rarely, frequent changing of stool consistency, hard or lumpy stools, straining during bowel movement, passage of mucous, feeling of incomplete evacuation, recurrent/multiple abdominal hernias (13.6% vs 7.1% vs 11.2%) Gynaecology: prolapse (pelvis, rectal, uterine) (0% vs 3.6% vs 15.3%) MSK/Orthopaedics: MSK/CWP (31.2% vs 89.3% vs 92.9%), joint dislocation/instability (9.1% vs 17.9% vs 38.8%), arachnodactyly (9.1% vs 28.6% vs 50%), arm span-to-height ratio (0% vs 3.6% vs 14.3%) Orthodontics: dental crowding/high narrow palate (18.2% vs 5.6% vs 69.4%) Miscellaneous: fatigue, daytime sleepiness Negative affect: fear of movement Miscellaneous: fatigue Hobbies/daily activities: fatigue affects activities HSD/hEDS groups had significant impairment of health-related QoL, complaints of generalised pain and self-reported symptoms including fear of movement, fatigue, daytime sleepiness, gastrointestinal concerns and dysautonomia Folci & Capsoni (2016) [ 26 ] Dermatology: thin skin, elastic skin Gastroenterology: abdominal discomfort, alternating bowel MSK/Orthopaedics: recurrent sprains, joint pain, pain in the TMJ, dislocate TMJ, twist and stretch thoracic-lumbar spine, axial and peripheral joint mobility, widespread joint hypermobility, extra-range mobility (knees, elbows, fingers) Rheumatology: generalised arthralgia, myalgia, diffuse arthralgia (shoulders, ankles, wrists, knees) Urology: difficult urination, dysuria, pollakiuria Miscellaneous: persistent fatigue, tendonitis (wrists and ankles), lower limb paraesthesia, sleep disturbance, weight gain, chewing problems Cognitive: poor concentration Mood disorder: depressive mood Negative affect: frustration Miscellaneous: fatigue, sleep disturbance, pain Daily living: bedridden, change in lifestyle, heavy impact on life Hobbies/daily activities: ceased physical activities Clinical complexity and the multidisciplinary importance of an unexpectedly common disease that still tends to be under-recognised. Early diagnosis is essential to avoid long and unnecessary diagnostic paths. Management requires a coordinated intervention including patient education, personalised physiotherapy and multidisciplinary medical collaboration Baeza-Velasco, et al. (2016) [ 27 ] ANS/Cardiology: dysautonomia; tachycardia Dermatology: thin skin, easy bruising, thin and hyper-extensible skin Gastroenterology: constipation, abdominal pain, dysphagia, gastroesophageal reflux, bloating, chronic nausea, food intolerances, painful swallowing, painful digestion, nausea, vomiting Genetics: unequivocally affected first degree relative Haematology: haemorrhages (nasal & gingival) MSK/Orthopaedics: recurrent dislocations, MSK pain, chronic MSK pain, recurrent blocks, recurrent sprains, TMJ dislocation, mild scoliosis Neurology: migraine Respiratory: respiratory dysfunction Rheumatology: chronic arthralgia Miscellaneous: Marfanoid habitus, chronic fatigue, hyperosmia, enhanced audition (hyperacousia), touch sensitivity (cutaneous hyperesthesia), proprioception dysfunction (clumsiness, frequent trips and falls), chronic fatigue, sleep disturbances, lack of appetite, weight loss, amenorrhea, masticatory muscle pain Anxiety disorder: panic attacks without agoraphobia Eating disorder: eating avoidance, AN, eating behaviours, distorted body image, fear of gaining weight Mood disorder: depression Negative affect: depressive feelings Substance use disorder: cannabis dependence Miscellaneous: pain, fatigue, sleep disturbances, self-injurious behaviours Education: bullying experiences Substance use: cannabis dependence Features and common co-occurring problems may favour difficulty eating, significant weight loss and eating disorders such as AN with consequent poor nutrition. The relationship with eating problems warrants more clinical and research attention Lee and Strand (2017) [ 28 ] Cardiology: tachycardia, syncope, postural hypotension Dermatology: bruise easily, thin skin, scar fissure, atopic, atrophic scars Gastroenterology: bloating, nausea, involuntary vomiting, dysphagia, weight loss, hiatus hernia, mild esophagitis MSK/Orthopaedics: general joint hypermobility, joint pain, dislocations, lumbar lordosis, chronic compartment syndrome, sprains Orthodontics: overbite, dental crowding, high/narrow palate Miscellaneous: diffuse pain Eating disorder: eating disorder/behaviours Miscellaneous: somatic conditions, pain NS Heterogeneous presentation. EDS symptoms may resemble or mask an underlying eating disorder, and vice versa. GI manifestations could be a risk factor for developing disordered eating Berglund, et al. (2015) [ 29 ] MSK/Orthopaedics: back pain (94%), cervical back pain (82%), thoracic back pain (74%), lumbosacral back pain (81%) Miscellaneous: tiredness Anxiety disorder: anxiety (74.8%) Mood disorder: depression (22.4%) Miscellaneous: tiredness Lifestyle: daily life A lower health-related QoL was found among EDS middle-aged individuals. Probable anxiety and depression were detected. Important to explore the factors behind these results and what initiatives can be taken to alleviate the situation for this group Clark, et al. (2014) [ 30 ] ANS (70% vs 12%)/Cardiology: light headedness, fainting, dizziness, PoTS (7.8%) Functional difficulties: gross motor activities, fine motor activities, organisation, impaired co-ordination, ability at games, ball skills, impaired balance, obstacle avoidance Gastroenterology (71% vs 9%): nausea, constipation, diarrhoea, stomach ache MSK/Orthopaedics: Knee pain (86%), lower back pain (83%), elbow pain (39%), foot pain (56%) Rheumatology: fibromyalgia (19% vs 0%) Miscellaneous: CFS (31% vs 1%), CWP (86%) Developmental disorder: DCD/dyspraxia (56% vs 19%); Miscellaneous: pain NS Clinicians should assess for broader neurophysiological symptoms in patients presenting with CWP in order to understand and better manage this condition. Adds to the growing body of evidence that recognises the multifactorial manifestations and the need to be recognised and treated holistically. Need to explore effective interventions that ameliorate the debilitating symptoms Inayet, et al. (2018) [ 31 ] Gastroenterology: abdominal pain (61% vs 28%), diarrhoea (33% vs 9%), constipation (54% vs 17%), centrally mediated abdominal pain syndrome (10% vs 3%), functional biliary pain (1% vs 1%); Oesophageal disorders: functional chest pain, (7% vs 1%), functional heartburn (33% vs 11%), globus (3% vs 1%), functional dysphagia (14% vs 3%); Gastroduodenal disorders: functional dyspepsia (61% vs 7%), belching disorders (11% vs 4%), nausea and vomiting disorders (4% vs 1%), rumination syndrome (3% vs 1%); Bowel disorders: IBS (23% vs 7%), functional constipation (36% vs 11%), functional diarrhoea (21% vs 6%), functional abdominal bloating/distension (26% vs 7%), unspecified functional bowel disorder (56% vs 24%); Anorectal disorders: faecal incontinence (2% vs 1%), functional anorectal pain (4% vs 2%) QoL QoL A greater understanding of functional GI symptoms may give further understanding to the aetiology of GI symptoms in individuals not formally diagnosed with connective tissue abnormalities and may give insight into the causes of functional GI disorders and IBS Albayrak, et al. (2015) [ 32 ] Localised pain: neck (20%), low back (32.2%), knee (27.8%), back (5.2%), ankle (4.3%), wrist (8.7%), other joint (1.7%) Miscellaneous: physical function, role physical, bodily pain, general health, physical component summary, fatigue, sleep quality Mood disorder: depression QoL: impaired Miscellaneous: bodily pain, role emotional, mental health, mental component summary, vitality, sleep quality, fatigue Lifestyle: vitality QoL: impaired Social relationships: social function Increased depression levels, fatigue and diminished QoL are common. One factor may trigger or aggravate another. Assessments should focus on the pain complaint, psychological problems, fatigue, sleep patterns, and QoL. A holistic approach to the examination, assessment, thorough questioning and a multidisciplinary treatment regimen Gaisl, et al. (2017) [ 33 ] Respiratory: OSA (32% vs 6%), hypopneas (64%), apnoeas (36%) Miscellaneous: fatigue, day time sleepiness Negative affect: depressive symptoms Miscellaneous: fatigue QoL: lower OSA is highly prevalent and under-recognised and contributes to fatigue, daytime sleepiness and impaired QoL in this population. Patients with EDS and excessive daytime sleepiness should be evaluated for OSA Zeitoun, et al. (2013) [ 34 ] Gastroenterology: heartburn (68.7%) regurgitations (68.7%), decubitus (62.6%), dysphagia (62.6%), epigastric pain (78.8%), nausea (70.8%), postprandial fullness (67.2%), belching (70.5%), IBS (48%), functional constipation (46%) Orthodontics: erosion of dental enamel (51.5%) Respiratory: chronic cough (36.2%), laryngitis (56.8%), asthma (45%) QoL QoL Digestive manifestations are extremely common, most frequently nonspecific and not serious but with major consequences on QoL. A systematic clinical assessment of the EDS population is required. Improve therapeutic management Fikree, et al.

There is an over-representation of reflux hypersensitivity and oesophageal hypomotility. More likely if JHS patients have comorbid PoTS Mastoroudes, et al. (2012) [ 36 ] Gynaecology: heaviness/dragging (28.3% vs 5%), discomfort (25% vs 5%), sex interference (bulge) (27% vs 10%), bowel interference (bulge) (23% vs 5%), straining to open bowels (61.7%), posterior compartment prolapse, bowels incompletely emptying MSK/Orthopaedics: backache (60% vs 23.3%), lower backache (36.7% vs 5%) QoL QoL Social relationships: sex interference (bulge) (27% vs 10%) The prolapse impacts QoL in the form of bowel evacuation symptoms and sexual dysfunction. The incidence of prolapse and the symptoms is significant, much may still go unnoticed. Provides knowledge about the pathophysiology of prolapse and obstructed defecation Mastoroudes, et al. (2013) [ 37 ] Gynaecology/Urology: urinary incontinence (73.3% vs 48.3%), urgency incontinence (62% vs 38.3%), stress incontinence (63.3% vs 36.7%) voiding dysfunction (63.3% vs 23.3%), straining to empty bladder (48.3% vs 13.3%), poor stream (38.3% vs 8.3%), postmicturition dribble (46.7% vs 30%), anterior prolapse, nocturia, nocturnal enuresis, intercourse incontinence, bladder pain Negative affect: embarrassment QoL QoL Incontinence is a source of embarrassment. Clinicians rarely acknowledge the impact it has on QoL. A large proportion of time is spent in rheumatology and hypermobility clinics with an insignificant amount of time spent asking about gynaecological issues. Under-diagnosis may be due to underreporting of symptoms or failure by GPs and rheumatologists to routinely screen for these symptoms. A systematic approach may be more effective in identifying these cases. A high prevalence of incontinence justifies the need for an integrated continence pathway within specialised hypermobility units Puledda, et al. (2015) [ 38 ] ANS/Cardiology: orthostatic hypotension (36.3%), PoTS (15.2%), mitral valve collapse (21.1%), arrhythmias (9.1%) Dermatology: psoriasis (12.1%) Gastroenterology: GORD (57.6%), chronic gastritis (30%), hiatal hernia (12.1%), celiac disease (9%) Gynaecology: urogynaecological prolapses and stress incontinence (12.1%) MSK/Orthopaedics: TMJD (18.2%) Neurology: Migraines: pulsating pain (75.8% vs 80.3%), constrictive pain (24.2% vs 19.7%), unilateral pain (36.4% vs 37.9%), bilateral pain (36.4% vs 39.4%), bilateral and unilateral (27.3% vs 22.7%), photophobia (100% vs 89.4%), phonophobia (78.8% vs 94%), osmophobia (54.6% vs 41%), nausea (91% vs 80.3%), vomiting (48.5% vs 48.5%), visual aura (36.4% vs 39.4%), sensory aura (3% vs 4.54%), speech aura (3% vs 1.5%) Respiratory: allergic asthma (15.2%) Rheumatology: Raynaud’s phenomenon (18.2%) Miscellaneous: multiple medication allergies (27.3%), inner ear dysfunction (18.2%), ANA positivity (6%) Anxiety disorder: anxiety with panic attacks (51.2%) Mood disorder: mood disturbances (36.4%), bipolar disorder (6%) Psychosis: psychotic disorder (3%) NS Migraine has a high impact on QoL in these patients. Although associated it must always be recognised separately and not contemplated solely as one of the manifestations of the disease. Adequate migraine therapy is essential in these patients and should not be delayed, to allow a lower risk of migraine-associated disability Bulbena-Cabre, et al.

Self-reported clinical characteristics were more severe for those with mechanical symptoms, longer symptom duration, shoulder dislocations, feeling the shoulder is loose, and additional discomfort, received supplemental treatment. Importance of addressing mechanical symptoms in the shoulder during treatment to fully cover and understand the patients’ impairments Berglund & Björck (2012) [ 42 ] Miscellaneous: mucosal problems, oral problems, nasal problems, eye problems, genital problems, physical pain, handicap, functional limitation Negative affect: felt insecure, felt tense, difficulty relaxing, felt embarrassed, life has been less satisfactory, psychologic discomfort Lifestyle: life has been less satisfactory Women with EDS report a low oral health related QoL as measured with the OHiP-14. Particularly in physical pain, psychologic discomfort, and handicap. This demonstrates that also the oral health-related QoL is impeded by the disorder De Baets, et al.

Complex experiences of having flexible bodies and restricted lives. Pain, fatigue and weakness demand attention and resolution, causing individual suffering. HCPs need to develop an ethical attitude and sensitivity in listening, and acknowledge bodily experiences to understand the nature of this illness
An integrated approach in the management may provide a deeper understanding, better clinical decision‐making and improved possibilities for recovery

Venn diagram of the biopsychosocial impact of HSD/EDS
Limb hyperextension, joint flexibility, pain and dislocations are the most recognised symptoms of EDS and HSD, frequently reported throughout studies. One qualitative study [ 23 ] described how these MSK symptoms, like having a flexible body, can cause restrictions to daily living. Another [ 24 ] described how involvement from a specialist hypermobility physiotherapist improved their understanding of their own bodies via a two-way learning process which in turn motivated these individuals to engage in appropriate self-management of their condition. Within assessments of EDS/HSD, individuals are subject to dermatological evaluation [ 25 ], this is because skin hyperextensibility is as common as MSK symptoms [ 9 , 26 ] with additional dermatological symptoms identified such as, thin skin [ 27 – 29 ] and abnormal scarring [ 9 , 19 ]. A significant number of participants in one study [ 19 ] suggested that the MSK and skin symptoms began as early as childhood yet despite these widely recognised and long-standing symptoms, the condition is often underdiagnosed [ 25 ].
Pain management specialists [ 21 ] can refer patients to be evaluated for a joint hypermobility condition due to the high prevalence of pain reported by this population. The pain experienced by these individuals affects the entire body including, but not limited to, back (94%) [ 30 ], knee (86%) [ 31 ], abdominal (61%) [ 32 ], foot (56%) [ 31 ], elbow (39%) [ 31 ] and neck (20%) [ 33 ]. The intensity of the pain ranges from, tiring and exhausting (93%) [ 19 ], chronic and constant (67%) [ 19 ] and severe to very severe (66%) [ 18 ]. Prevalence of fatigue is also reported to be as high as 77% [ 21 ] and can be measured using the Epworth Sleepiness Scale (ESS) [ 26 , 34 ] or Fatigue Severity Scale (FSS) [ 25 ]. Fatigue and impaired sleep quality are considered to be a simultaneous experience to pain, as described by individuals with EDS/HSD, interfering with their ability to live a good QoL [ 23 , 33 ]. Interestingly, some studies suggested that the presence of pain increases the likelihood of an individual with EDS/HDS also having a comorbid psychiatric disorder [ 9 , 22 ].
Gastrointestinal symptoms are extremely common in this population, reported in over half of the included studies, therefore involvement from a gastroenterologist is not unusual. One retrospective study found that over 60% of their sample disclosed at least one gastrointestinal symptom at the time of their hEDS diagnosis [ 17 ]. Abdominal pain (50%) and nausea (50%) in this sample were the two most common gastrointestinal symptoms [ 17 ]. This was supported by another study, reporting higher prevalence found in an EDS sample, 79% and 71% respectively [ 35 ]. Furthermore, one study with a hEDS sample and accompanying gastrointestinal symptoms were significantly more likely to use medications for these symptoms (anti-secretory, antacids, laxatives) than the control group ( p < 0.01) [ 32 ]. Though these symptoms are not considered serious, they can cause a detrimental impact to the individual’s QoL, as assessed by the Gastrointestinal Quality of Life Index (GIQLI) [ 35 ].
Dysautonomia is condition characterised by a malfunction of the ANS with associated symptoms such as dizziness, fainting and light headedness [ 31 ]. One study [ 21 ] found prevalence of dysautonomia at 70% amongst a hEDS/HSD sample, with those carrying this diagnosis significantly more likely to suffer with related symptoms, have an impaired QoL and exhibit exercise avoidance behaviours, subsequently leading to a more sedentary lifestyle. Individuals with dysautonomia and attempting to engage in physical therapy programmes are limited by the related symptoms, leading to a lack of significant improvement in their overall condition via such interventions [ 21 ]. This ANS malfunction is also responsible for postural tachycardia syndrome (PoTS), with prevalence in individuals with EDS/JHS ranging from 8% [ 31 ] to 64% [ 20 ]. Those with both JHS and PoTS were found to be at a significantly increased risk of gastrointestinal symptomology ( p ≤ 0.05) [ 17 ], with higher reflux scores, regurgitation and dysphagia [ 36 ].
Fibromyalgia, a chronic widespread pain (CWP) condition, has been identified in a small number of the included studies as a comorbid condition. Prevalence of the diagnosis ranges from as small as 5% [ 25 ] up to 41% [ 20 ] amongst benign JHS (BJHS) and EDS samples respectively. Interestingly, individuals with hEDS were significantly more likely to report this comorbid diagnosis if they likewise presented with gastrointestinal manifestations and chronic pain ( p < 0.02) [ 17 ]. Complaints of tiring and exhausting pain were further found to be a predictive factor of a fibromyalgia diagnosis within one hEDS sample [ 19 ]. Individuals with joint hypermobility conditions have overlapping symptoms as those with fibromyalgia [ 31 ], therefore the increased likelihood of also having this CWP condition could be attributed to this reason.
Women are much more likely to be affected by this condition and as a result endure clinically significant urogynaecology-related symptoms like, pelvic organ prolapse ( p < 0.01) [ 37 , 38 ] as an example. These symptoms can have a detrimental impact on QoL, as measured by the Prolapse Quality of Life (P-QOL) [ 37 , 38 ]. The impact of gynaecological issues is rarely acknowledged by the rheumatologists and primary care practitioners who predominantly make the diagnosis [ 38 ]. One study [ 37 ] found prolapse symptoms to be clinically significant across the general health perception, physical limitation, social limitation, personal relationships, emotions, sleep/energy and severity domains ( p ≤ 0.05), as well as contributing to sexual and bowel dysfunctions. In addition to this, urinary incontinence was also cited as a clinically significant symptom within a BJHS sample ( p < 0.01) with prevalence over 70% and a cause of significant embarrassment to women [ 38 ].
Neurological assessments conducted by neurologists found manifestations in this population to include migraines and headaches, with severity of symptoms measured by the Migraine Disability Assessment (MIDAS) and HIT-6 [ 39 ]. Individuals with hEDS and migraines are significantly more likely to have an earlier onset of symptoms than those without hEDS (13 vs 17 years, p < 0.01), a higher number of days per month migraine episodes (15 vs 9 days, p = 0.01) and experience photophobia ( p = 0.05) [ 39 ]. The migraine-related pain hEDS experience has been described as pulsating (76%) and constrictive (24%), with these individuals being significantly more likely to use migraine-related medication (e.g., NSAIDS, analgesics, triptans) ( p ≤ 0.05) [ 39 ]. This is an example of the substantial impact of migraines on the QoL of hEDS individuals. However, it is still recommended that migraines are seen and managed as a separate condition rather than a sole manifestation of hEDS [ 39 ].
Respiratory symptoms have been inconsistently reported throughout the included studies and are quite varied, suggesting a weak association between EDS and/or HSD individuals. However, one study [ 34 ] recognises obstructive sleep apnoea (OSA) as highly prevalent yet under-recognised in HSD when compared to control groups (32% vs 6%, p < 0.01), hypopneas being the most common respiratory event within this HSD sample (64%) [ 34 ]. It may be that HSD individuals suffering from excessive daytime sleepiness and fatigue should also be assessed for OSA as a potential cause [ 34 ].
Almost half of included studies suggested EDS/HSD individuals were significantly more likely to experience mood and anxiety disorders than the general population ( p < 0.01) [ 22 ]. The most frequently cited mood disorder being depression with prevalence ranging from 22% [ 30 ] to 69% [ 19 ], with anxiety having a higher prevalence at 75% [ 30 ]. The two disorders were most often measured in studies using the Hospital Anxiety and Depression Scale (HADS) [ 30 , 40 ], whilst antidepressant and anxiolytic use was also noted within this sample [ 18 ]. Additional diagnoses of both mood and anxiety disorders included: major depression (ranging from 8% [ 41 ] to 37% [ 41 ]), bipolar disorder (less than 10% [ 20 ]), phobias [ 40 ] and post-traumatic stress disorder (PTSD) [ 9 ], though the latter were reported in less than 5%. Notably, one study found that HSD individuals experiencing muscle and body pain and gastrointestinal symptoms were at a significantly increased risk of experiencing depression ( p < 0.01 and p < 0.03 respectively), with gastrointestinal symptoms alone being significant for anxiety ( p < 0.01) [ 22 ].
Negative affect is the experience of negative emotions and psychological distress. This population described being fearful, specifically fear of movement [ 18 , 26 , 42 ]. One study utilised the Tampa Kinesiophobia Scale (TSK) to measure this, finding a statistically significant difference between individuals with EDS/HSD and without, including within the activity avoidance and somatic focus subscales ( p < 0.01) [ 26 ]. Additionally, catastrophising (a cognitive distortion) was cited across two included studies. A sample of hEDS individuals with high levels of anxiety were found to score significantly higher in pain catastrophising ( p < 0.01), as measured by the Pain Catastrophizing Scale (PCS) [ 18 ]. A qualitative study further offered an explanation to the above findings, describing how prior experiences of injuries have led to heightened levels of anxiety, resulting in participants catastrophising about future injuries [ 24 ]. The anxiety, fear of movement and pain catastrophising is a direct response to their unpredictable symptoms, resulting in individuals modifying or restricting their activities to avoid pain and potential injuries [ 26 ].
Three case studies of young female women described EDS/JHS manifestations that contributed to the development of eating disturbances [ 28 , 29 ]. Such disturbances included painful eating experiences [ 43 ] and selective eating behaviours due to temporomandibular pain and dislocations [ 28 ], as well as eating avoidance due to gastrointestinal problems like nausea and vomiting [ 28 ]. One female was diagnosed with the eating disorder anorexia nervosa (AN) and underwent an enhanced cognitive behavioural therapy programme to improve eating behaviours, body image and social functioning [ 29 ]. Notably, this study is the only that referenced a CBT programme to be utilised within this population, though specifically for an eating disorder. Additionally, their presenting symptoms which had primarily been attributed to AN could also be attributed to the EDS, specifically gastrointestinal symptoms which caused disordered eating [ 29 ].
Three of the studies reported a comorbid diagnosis of attention deficit hyperactivity disorder (ADHD). One study found this behavioural disorder to be more frequent in EDS/HSD individuals than in the general population (5% vs 3%), though only significantly higher within those with HSD ( p < 0.01) [ 22 ]. The other two studies reported a slightly higher prevalence of ADHD in EDS and hEDS samples, 7% [ 9 ] and 11% [ 17 ] respectively. The association between ADHD and EDS/HSD however, is weak and unclear and would warrant further exploration.
Including the psychiatric disorders already outlined, prevalence of others, though relatively low, have also been recognised such as, schizoaffective disorder (0.3% [ 22 ] and 1% [ 9 ]), schizotypal disorder (0.3% [ 22 ] and 1% [ 9 ]) and borderline personality disorder (4%) [ 9 ]. One study [ 41 ] examined suicidal behaviours in women with HSD finding that 31% of the sample had previously attempted suicide whilst 60% presented with a mild suicidal risk. Those with a history of suicidal attempt were also significantly more likely to have personality disturbances ( p < 0.01), major depression ( p < 0.03) and anxiety disorders ( p < 0.04) [ 41 ].
The education of EDS/HSD individuals is significantly impacted, with individuals dropping out of education [ 20 ], being unable to enrol full-time [ 19 ] and when in school being subjected to bullying due to their physical appearance [ 28 ]. Similarly, these individuals also face difficulties in their professional lives, feeling unable to pursue their desired careers [ 20 ] or having to change their current role and handle less responsibilities [ 19 ]. These individuals additionally need to consider the accessibility of their workplace and their working environment to ensure it meets their needs and capabilities [ 44 ]. Changes to the individuals desired career path and working environment can contribute to reduced job satisfaction and feeling a lack of financial independence [ 44 ].
Individuals with EDS/HSD are often forced to abandon their favourite hobbies or quit their athletic pursuits as a result of the many physical limitations that accompany the condition [ 20 ]. Though this is not applicable to all, some instead choose to persevere and make modifications appropriate to what they are capable of achieving and to pace themselves [ 24 ]. Whilst others simply lacked the energy, as well as the physical limitations, to participate in recreational activities and activities of daily living, such as doing housework [ 23 ]. They would often have to evaluate their energy levels and how they should distribute their energy throughout the day in order to complete simple daily household tasks (e.g., making food and going shopping) and fulfil their personal care needs (e.g., taking a shower) [ 22 ].
A qualitative study [ 6 ] examining the psychosocial influence in the daily life of individuals with EDS demonstrates the difficulties in maintaining social networks as a result of the debilitating symptoms that accompany the condition. They identified social isolation behaviours in some individuals due to not being able to participate in certain activities and the inability to make long-term plans. In order to be able to attend social events, these individuals must plan rest days in advance to conserve their energy, as previously discussed [ 22 ]. However, due to these behaviours and adjustments, these individuals often feel like they must justify themselves to friends and family who, like many HCPs, lack proper understanding and insight into the condition.
Referrals for joint hypermobility assessments can also be made by cardiologists and orthopaedists [ 21 ]. Additional physical and psychological manifestations inconsistently cited across the 32 studies but noteworthy included: haematology [ 9 , 22 , 28 ], orthodontics [ 26 , 29 , 35 ] (e.g., dental crowding), ophthalmology [ 20 , 22 ] (e.g., glaucoma), endocrinology [ 20 ], genetics [ 28 ], immunology [ 20 ], infectious disease [ 20 ], oncology [ 20 ], functional difficulties (e.g., DCD/dyspraxia) [ 31 ], learning difficulties (e.g., dyslexia [ 20 , 22 ]), developmental disorders (e.g., Asperger disorder [ 9 ]) and substance use disorder (e.g., alcohol/substance use abuse [ 41 ]). Individuals with EDS/HSD also engage in complementary therapies such as acupuncture and massage [ 20 ].
