Shoulder function, pain and health related quality of life in adults with joint hypermobility syndrome/Ehlers–Danlos syndrome-hypermobility type

Imaging modalities for atraumatic shoulder hypermobility: a scoping review

BACKGROUND

Objective measures from imaging studies have the potential to assist in timely diagnosis of atraumatic shoulder hypermobility to better guide management. The aim of this scoping review is to examine imaging modalities and techniques used to characterize atraumatic shoulder hypermobility.

METHODS

MEDLINE, EMBASE, SPORTDiscus, Cochrane Library, and Web of Science were searched up to May 2024 for any primary study investigating imaging findings seen in atraumatic shoulder hypermobility. Patients with unilateral instability were excluded given its frequent association with traumatic origin.

RESULTS

Eighteen observational studies met inclusion criteria. Results were divided into outcomes relating to capsular redundancy, glenohumeral anatomy, and muscle activation. Five studies using magnetic resonance arthrography (MRA) demonstrated statistically significant increases in capsular cross-sectional area (CSA), while a significant superior capsular elongation was reported by two studies in patients with multidirectional instability (MDI). Labrocapsular distance, glenocapsular ratio, and the presence of a combined sail and triangle sign on MRA were highly sensitive and specific parameters for identifying MDI. There were inconsistent findings for alterations of glenohumeral anatomy. Ultrasound assessments of acromiohumeral distance (AHD) were significantly increased in patients with MDI, but not in shoulders with hypermobility alone. Similarly, muscle activity measured by electromyography or glenohumeral translations differed significantly in patients with MDI, but not in those with hypermobility alone.

CONCLUSION

Radiographic markers of capsular redundancy (e.g., CSA, labrocapsular distance, glenocapsular ratio), AHD, and muscular activity are useful in the diagnosis of MDI. However, there are no definitive imaging markers for diagnosing atraumatic shoulder hypermobility without MDI.

A Multidisciplinary Approach to Hypermobility Spectrum Disorder, Raynaud's Phenomenon, and Biomechanical Soft Tissue Injuries in an Adolescent Boy: A Case Report

A 16-year-old male with hypermobility spectrum disorder (HSD) and Raynaud's phenomenon (RP) was referred to a clinical exercise physiologist (CEP) by their pediatric rheumatologist. The patient presented with arthralgia in the left knee and shoulder. Specifically, the left knee presented discomfort during activities of daily living (ADL), and the left shoulder had a reduced range of motion resulting from pain. Finally, complaints of painful fingers were also significant due to increased RP flare-ups during winter. A posture analysis was conducted, indicating relatively poor posture. Range of motion and manual muscle testing were suboptimal in the shoulders, but optimal in the knees and hips. The Kendal test, patella compression test, and Clarke's sign were conducted due to knee pain. Functional tests included a pelvic bridge, squat, Neer's test, and wall push-up. Finally, the modified pediatric clinical test of sensory interaction in balance (mPCTSIB) was completed to determine the interaction between balance systems. Analysis of all the tests conducted above confirmed the diagnosis of HSD and also indicated scapula dyskinesia, supraspinatus impingement, and patellofemoral pain syndrome. Consequently, the CEP treatment focused on strengthening the foot, knee, and hip kinetic chain, as a 12-week home program, along with hand exercises as needed to aid in the pain and stiffness experienced during RP flare-ups. The physiotherapist treatment was more hands on in the use of myofascial release, electrotherapy, taping, and posture correction of the neck and shoulder over four in-house visits. Finally, a 6-month follow-up was conducted by the CEP, in which the patient showed improvement with a pain-free range of motion and the ability to optimally conduct ADLs.

The Effectiveness of Conservative Interventions on Pain, Function, and Quality of Life in Adults with Hypermobile Ehlers-Danlos Syndrome/Hypermobility Spectrum Disorders and Shoulder Symptoms: A Systematic Review

Objective

To synthesize the evidence on conservative interventions for shoulder symptoms in hypermobile Ehlers-Danlos Syndrome (hEDS) and hypermobility spectrum disorder (HSD).

Data Sources

A literature search was conducted using data sources Medline, PEDro, CINAHL, AMED, Elsevier Scopus, and the Cochrane Library from January 1998 to June 2023.

Study Selection

The review included primary empirical research on adults diagnosed with hEDS or HSD who experienced pain and/or mechanical shoulder symptoms and underwent conservative interventions. Initially, 17,565 studies were identified, which decreased to 9668 after duplicate removal. After title and abstract screening by 2 independent authors, 9630 studies were excluded. The full texts of the remaining 38 were assessed and 34 were excluded, leaving 4 articles for examination.

Data Extraction

Two authors independently extracted data using a predefined extraction table. Quality assessment used the Joanna Briggs Institute checklists and the Template for Intervention Description and Replication.

Data Synthesis

The review covered 4 studies with a total of 7 conservative interventions, including exercise programs, kinesiology taping, and elasticized compression orthoses. Standardized mean differences were calculated to determine intervention effects over time. The duration of interventions ranged from 48 hours to 24 weeks, showing positive effect sizes over time in the Western Ontario Shoulder Instability Index, pain levels, improved function in activities of daily living, and isometric and isokinetic strength. Small to negligible effect sizes were found for kinesiophobia during completion of exercise programs.

Conclusions

Shoulder symptoms in hEDS/HSD are common, yet significant gaps in knowledge remain regarding conservative interventions, preventing optimal evidence-based application for clinicians. Further research is necessary to explore the most effective intervention types, frequencies, dosages, and delivery methods tailored to the specific requirements of this patient population.

Impact of chronic wrist hypermobility on proprioception, strength, and functional performance in young adults

BACKGROUND

Chronic joint hypermobility has been attributed to repetitive ligamentous microtrauma, benign joint hypermobility syndrome (BJHS), or genetic connective tissue disorders that lead to pain and functional impairment, especially among females. Chronic wrist hypermobility (CWH) prevalence, etiology, and effects on proprioception, strength, and function have yet to be established.

PURPOSE

This pilot study aimed to determine the CWH prevalence among adults; its effects on proprioception, strength, and function; and whether these effects are gender based.

STUDY DESIGN

This was a quasi-experimental cross-sectional study.

METHODS

Ninety wrists (55 participants, mean age 27.46 years) with no wrist range of motion (ROM) restrictions or previous trauma for ≥6 months were screened for CWH based on an exploratory set of diagnostic criteria. Fifty-eight wrists (34 adults) were allocated to a CWH group, and 32 wrists (21 adults) were allocated to a healthy control group. Twenty-five CWH and 25 healthy control matched (gender, age, and handedness) participants were compared. Assessment included the active wrist joint position sense test, hand-held dynamometry for wrist extension and grip strength, and the patient-rated wrist evaluation for function. Testers were blinded to group allocation.

RESULTS

A 64.4% CWH prevalence existed among CWH participants, who were mostly asymptomatic females (74%). Frequent etiologic factors were midcarpal (96.5%) and scapholunate (39%) instabilities and BJHS (37%), which was higher among females (30%) than males (8%). Independent t-tests showed statistically significant (p < 0.05) group differences in wrist proprioception, wrist isometric extension, grip strength, and function with moderate-high (0.41-0.75) effect size. No significant gender differences existed in proprioception and function.

CONCLUSIONS

CWH is very prevalent among functional independent young adults with atraumatic midcarpal and intercarpal ligamentous laxities and BJHS. CWH prevails among women and adversely affects wrist proprioception, strength, and function. The study's specific CWH diagnostic criteria may be useful for clinicians to identify and timely manage impacted individuals by CWH.

One-year effectiveness of high-load compared with low-load strengthening exercise on self-reported function in patients with hypermobile shoulders: a secondary analysis from a randomised controlled trial

OBJECTIVES

To investigate the long-term effectiveness of high-load versus low-load strengthening exercise on self-reported function in patients with hypermobility spectrum disorder (HSD) and shoulder symptoms.

METHODS

A secondary analysis of a superiority, parallel-group, randomised trial (balanced block randomisation 1:1, electronic concealment) including adult patients (n=100) from primary care with HSD and shoulder pain and/or instability ≥3 months. Patients received 16 weeks of shoulder exercises (three sessions/week): HEAVY (n=50, full-range, high-load, supervised twice/week) or LIGHT (n=50, neutral/mid-range, low-load, supervised three times in total). The 1-year between-group difference in change in self-reported function was measured using the Western Ontario Shoulder Instability Index (WOSI, scale 0-2100, 0=best). Secondary outcomes were self-reported measures including changes in shoulder-related symptoms, function, emotions and lifestyle, quality of life, patient-perceived effect, treatment utility and adverse events. A blinded analyst conducted the analyses using linear mixed model repeated measurements analysis.

RESULTS

One-year data were available in 86 out of 100 participants (79% women, mean age 37.8 years) (LIGHT 84%, HEAVY 88%). The mean WOSI score between-group difference favoured HEAVY (-92.9, 95% CI -257.4 to 71.5, p=0.268) but was not statistically significant. The secondary outcomes were mostly inconclusive, but patients in HEAVY had larger improvement in the WOSI emotions subdomain (-36.3; 95% CI -65.4 to -7.3, p=0.014). Patient-perceived effect favoured HEAVY anchored in WOSI-emotions (55% vs 31%, p=0.027) and WOSI-lifestyle (50% vs 29%, p=0.042).

CONCLUSION

High-load shoulder strengthening exercise was not superior to low-load strengthening exercise in improving self-reported function at 1 year. High-load strengthening exercise may be more effective in improving patient emotions about shoulder pain and function, but more robust data are needed to support these findings.

Hypermobile Ehlers-Danlos syndrome/hypermobility spectrum disorders in older women: A feasibility study

INTRODUCTION

Hypermobile Ehlers-Danlos syndrome and hypermobility spectrum disorders cause joint instability, chronic pain, fatigue and progressive multisystemic dysfunction, increasing symptom burden and decreasing quality of life. Researchers know little about how these disorders progress in women as they age.

OBJECTIVE

This research aimed to determine the feasibility of an internet-based study to understand the clinical characteristics, symptom burden and health-related quality of life in older women with symptomatic hypermobility disorders.

METHODS

This cross-sectional, internet-based survey studied recruitment methods, suitability and usability of survey instruments and obtained baseline data on women aged 50 and older with hEDS/HSD. Researchers recruited participants from a Facebook group for older adults with Ehlers-Danlos syndrome. Outcome measures included health history, the Multidimensional Health Assessment Questionnaire and the RAND Short Form 36 health survey.

RESULTS

Researchers recruited 32 participants from a single Facebook group within 2 weeks. Nearly all participants were satisfied with the survey length, clarity and navigation, with 10 participants providing free-text recommendations for survey improvement. The survey suggests a high symptom burden and poor quality of life in older women with hEDS/HSD.

CONCLUSION

The results support the feasibility and importance of a future internet-based comprehensive study about hEDS/HSD in older women.

Psychological factors and symptom duration are associated with exercise-based treatment effect in people with hypermobile shoulders: A secondary analysis of a randomised controlled trial

BACKGROUND

Shoulder symptoms are common in patients with hypermobility spectrum disorders (HSD), but few studies focus on identifying factors associated with treatment effects.

AIM

To identify baseline and clinical characteristics associated with a better outcome 16 weeks after starting an exercise-based treatment in patients with HSD and shoulder symptoms.

DESIGN

Exploratory secondary analysis of data from a randomised controlled trial.

METHOD

Self-reported treatment outcome was reported as change between baseline and follow-up after 16 weeks of high-load or low-load shoulder strengthening. Multiple linear and logistic regressions were used to investigate associations of patient expectations of treatment effect, self-efficacy, fear of movement, and symptom duration with change in shoulder function, shoulder pain, quality of life, and patient reported health change. All regression models were performed firstly with adjustments for covariates (age, sex, body mass index, hand dominance, treatment group, and baseline score of the outcome variable) and secondly with additional adjustments for exposure variables.

RESULTS

Expectations of complete recovery were associated with an increased odds of perceiving an important improvement in physical symptoms after a 16-week exercise-based treatment program. Higher self-efficacy at baseline seemed to be associated with improved shoulder function, shoulder pain and quality of life. A higher fear of movement seemed to be associated with increased shoulder pain and decreased quality of life. A longer symptom duration was associated with decreased quality of life.

CONCLUSION

Expectations of complete recovery, higher self-efficacy, lower fear of movement and shorter symptom duration seem to be important for better treatment outcomes.

A systematic review to compare physiotherapy treatment programmes for atraumatic shoulder instability

Background

Optimal physiotherapy treatment is uncertain for atraumatic shoulder instability (ASI), the primary aim of this systematic scoping review was to compare physiotherapy treatment programmes for people with ASI. The secondary aims were to evaluate outcome measures used and to compare the effectiveness of these programmes.

Methods

CINAHL, EMBASE and Medline databases were searched for studies, except single case studies, published between 1950 and July 2021. 12 critical appraisal items covered three domains; internal validity, transferability to wider population and reporting.

Results

Ten studies were included; one randomised controlled trial, 6 cohort studies and 3 case series. There were 491 participants. Treatment programmes included education, movement re-education, static posture correction, shoulder muscle strengthening, functional training, and adjuncts. All studies used patient reported outcome measures (PROMs), 7 of which reported a statistically significant improvement (p < 0.05) post-treatment. There was no clear relationship between programmes and outcomes. PROMs specific to shoulder instability were all found to detect statistically significant differences post-treatment.

Discussion

There does not appear to be one optimal physiotherapy treatment programme for ASI. Future studies should use PROMs that are valid in the shoulder instability population and use more outcome measures that are specific to impairments being targeted.

Management of Shoulder Instability in Patients with Underlying Hyperlaxity

PURPOSE OF REVIEW

Shoulder instability in patients with underlying joint hyperlaxity can be challenging to treat. Poorly defined terminology, heterogeneous treatments, and sparse reports on clinical outcomes impair the development of best practices in this patient population. This article provides a review of the current literature regarding optimal management of patients suffering from shoulder instability with concomitant hyperlaxity of the shoulder, from isolated shoulder joint hyperlaxity to congenital hypermobility spectrum disorders (HSD).

RECENT FINDINGS

Current research shows specialized physiotherapy protocols focused on strengthening of periscapular muscles and improvement of sensorimotor control are a promising non-surgical therapeutic avenue in certain patients, which can be augmented by device-based intervention in select cases. If surgical treatment is warranted, arthroscopic techniques such as pancapsular shift or plication continue to demonstrate favorable outcomes and are currently considered the benchmark for success. The long-term success of more recent innovations such as coracoid process transfers, conjoint tendon transfers, subscapularis tendon augmentation, and capsular reconstruction remains unproven. For patients affected by connective tissue disorders, treatment success is generally less predictable, and the entire array of non-operative and operative interventions needs to be considered to achieve the best patient-specific treatment results. In the treatment of shoulder instability and concomitant hyperlaxity, specialized physiotherapy protocols augmented by device-based interventions have emerged as powerful, non-operative treatment options for select patients. Successful surgical approaches have been demonstrated to comprehensively address capsular redundancy, labral lesions, and incompetence of additional passive stabilizers in a patient-specific fashion, respective of the underlying connective tissue constitution.

Clinical-functional features of individuals with Osteogenesis Imperfecta and Ehlers-Danlos syndromes: A scoping review of assessment tools and ICF model

BACKGROUND

Clinical-functional assessment of patients affected by Osteogenesis Imperfecta and Ehlers-Danlos Syndromes is essential for clinical management. However, there is no clear information on disease-specific tools of assessment for clinical practice, thus limiting quantification and management of the diseases-related impairments.

OBJECTIVE

The present scoping review was aimed at investigating the most common clinical-functional features and assessment tools in individuals with Osteogenesis Imperfecta and Ehlers-Danlos Syndromes, and to provide an updated International Classification of Functioning (ICF) model related to functional impairments for each disease.

METHODS

The literature revision was conducted on PubMed, Scopus and Embase databases. Articles reporting an ICF model of clinical-functional features and assessment tools for Osteogenesis Imperfecta and Ehlers-Danlos Syndromes individuals were included.

RESULTS

A total of 27 articles were included, 7 reporting an ICF model, and 20 reporting clinical-functional assessment tools. It was reported that patients with Osteogenesis Imperfecta and Ehlers-Danlos Syndromes show impairments in both Body Function and Structure, and Activities and Participation domains of the ICF. A heterogeneous number of assessment tools was found for both diseases regarding proprioception, pain, endurance to exercise, fatigue, balance and motor coordination, and mobility.

CONCLUSION

Patients with Osteogenesis Imperfecta and Ehlers-Danlos Syndromes show several impairments and limitations in Body Function and Structure, and Activities and Participation domains of the ICF. Thus, an appropriate and ongoing assessment of the disease-related impairments is necessary to improve clinical practice. Several functional tests and clinical scales can be used to assess the patients despite the heterogeneity of assessment tools found in previous literature.

Dynamic pediatric shoulder instability: Etiology, pathogenesis and treatment

Dynamic shoulder instability in children or adolescents, whose glenohumeral growth plates are still open, is a rare condition with an etiology that is hard to decipher. Atraumatic and recurrent forms are most common, contrary to adults. Disruptions to capsule and ligament maturation, muscle balance or bone growth can lead to glenohumeral instability. The etiology assessment, which needs to be multidisciplinary in atraumatic forms, aims to collect the medical history, analyze the direction of the instability, determine whether it is voluntary or involuntary, and look for a history of trauma, connective tissue abnormality, psychological disorder, neuromuscular pathology or congenital malformation. The initial treatment is conservative. It requires a multidisciplinary team when the shoulder instability is voluntary. Surgical treatment is reserved for symptomatic forms that do not respond to conservative treatment and have an impact on daily life and/or sports participation after a minimum of 6 months of well-conducted rehabilitation. The results of surgical stabilization mainly depend on the features of the instability, the anatomical structures damaged and the etiology. Episodes of recurrent instability in children/adolescents with open glenohumeral growth plates can fade in adulthood or can get worse with the development of structural damage. Early detection of poor outcomes and suitable treatment will help to limit the occurrence of osteoarthritis in the medium and long term. LEVEL OF EVIDENCE: Expert opinion.

The association between number of shoulder diagnoses and positive clinical tests with self-reported function and pain: A cross-sectional study of patients with hypermobile joints and shoulder complaints

BACKGROUND

Patients with hypermobility spectrum disorder (HSD) and shoulder complaints may suffer from symptoms related to shoulder instability, laxity, and hypermobility. It is currently unknown whether having a more complex clinical status with several diagnoses (i.e., anterior instability (AI), multidirectional instability (MDI), and/or symptomatic localised shoulder hypermobility (LSH), relates to higher functional impairments and pain.

OBJECTIVES

To investigate the associations between either ≤1, 2, or 3 clinical shoulder diagnoses (AI, MDI, and LSH) or the number (0-10) of positive clinical shoulder tests with shoulder function using the western Ontario shoulder instability index (WOSI, 0-2100, 0 = best) and pain intensity using numerical pain rating scale (NPRS, 0-10, 10 = worse).

DESIGN

Exploratory cross-sectional study.

METHOD

From a randomised controlled trial, baseline data from 100 participants with HSD and shoulder complaints for at least three months were included. Associations were investigated using linear regression models, adjusted for age, sex, body mass index, and hand dominance.

RESULTS

Compared with having ≤1 diagnosis, neither participants with two (WOSI 76.9, 95% CI -136.3, 290.0; NPRS 0.3, 95% CI -0.9, 1.5) nor three (WOSI 35.5, 95% CI -178.5, 249.6; NPRS 0.1, 95% CI -1.1, 1.3) clinical shoulder diagnoses had significantly worse shoulder function or pain. Likewise, the number of positive clinical shoulder tests was not associated with function (WOSI -20.8 95%CI (-55.3, 13.7)) or pain (NPRS -0.1 95%CI (-0.2, 0.1)).

CONCLUSIONS

In participants with HSD and shoulder complaints, having more additional shoulder diagnoses or increased number of positive shoulder tests were not related to functional impairments or pain intensities.

Societal participation in ehlers-danlos syndromes and hypermobility spectrum disorder, compared to fibromyalgia and healthy controls

Ehlers-Danlos syndrome and hypermobility spectrum disorder affect daily life. There is a lack of research that investigates how the disease affects aspects of participation. This study investigates whether there is a difference in the level of participation in society in persons with vascular EDS (N = 18), hypermobile EDS (N = 20), classical EDS (N = 4) and Hypermobility Spectrum Disorder (N = 27), compared to a healthy control group (N = 69) and fibromyalgia (N = 69). In this retrospective case-control study, the Ghent Participation Scale was completed by all participants. Each patient with EDS and HSD was matched by age and sex to healthy controls. The hEDS and HSD group were compared with the healthy control group and a positive control group (persons with fibromyalgia). The results show that there was a significant lower overall participation score for persons with hEDS/HSD compared to the healthy control group. In addition, significant differences were observed in the subscores self-performed activities and delegated activities in the hEDS/HSD group compared to healthy controls, being HEDS/HSD patients who obtained the lower scores. Further research is needed to obtain representative results of the participation level for the EDS/HSD population. In this way, interventions can be set up for patients with EDS in an evidence-based way and that are appropriate to the patient’s level of participation.

Short-term effectiveness of high-load compared with low-load strengthening exercise on self-reported function in patients with hypermobile shoulders: a randomised controlled trial

OBJECTIVES

To investigate the short-term effectiveness of high-load versus low-load strengthening exercise on self-reported function in patients with hypermobility spectrum disorder (HSD) and shoulder symptoms.

METHODS

A superiority, parallel-group, randomised trial (balanced block randomisation, electronic concealment) including adult patients (n=100) from primary care with HSD and shoulder pain and/or shoulder instability ≥3 months. Patients received 16 weeks of shoulder exercises (three sessions/week): HEAVY (n=50, full-range, high-load, supervised twice/week) or LIGHT (n=50, neutral/mid-range, low-load, supervised three times). The primary outcome was the 16-week between-group difference in self-reported function measured with the Western Ontario Shoulder Instability Index (WOSI, scale 0-2100, 0=best, minimal important difference 252 points). Secondary outcomes were self-reported measures including quality of life and clinical tests including shoulder muscle strength and range of motion. An intention-to-treat analysis with multiple imputation was conducted by a blinded biostatistician using linear regression.

RESULTS

93 of 100 patients (93%) completed the 16-week evaluation. The mean WOSI score between-group difference significantly favoured HEAVY (-174.5 points, 95% CI -341.4 to -7.7, adjusted for age, sex, baseline score, clustering around clinic). The secondary outcomes were inconclusive, but patients in HEAVY were less likely to have a positive shoulder rotation test >180°, and more likely to rate an important improvement in physical symptoms. There were no serious adverse events, but HEAVY was associated with more transient muscle soreness (56% vs 37%) and headaches (40% vs 20%).

CONCLUSION

High-load shoulder strengthening exercise was statistically superior to low-load strengthening exercise for self-reported function at 16 weeks and may be used in primary care to treat patients with HSD and shoulder pain and/or instability to improve shoulder function in the short term. Further studies are needed to confirm the clinical relevance, and patients should be supported to manage associated minor adverse events.

Heritable connective tissue disorders in childhood: Decreased health-related quality of life and mental health

The psychosocial consequences of growing up with Heritable Connective Tissue Disorders (HCTD) are largely unknown. We aimed to assess Health‐Related Quality of Life (HRQoL) and mental health of children and adolescents with HCTD. This observational multicenter study included 126 children, aged 4–18 years, with Marfan syndrome (MFS, n = 74), Loeys–Dietz syndrome (n = 8), molecular confirmed Ehlers–Danlos syndromes (n = 15), and hypermobile Ehlers–Danlos syndrome (hEDS, n = 29). HRQoL and mental health were assessed through the parent and child‐reported Child Health Questionnaires (CHQ‐PF50 and CHQ‐CF45, respectively) and the parent‐reported Strengths and Difficulties Questionnaire. Compared with a representative general population sample, parent‐reported HRQoL of the HCTD‐group showed significantly decreased Physical sum scores (p < 0.001, d = 0.9) and Psychosocial sum scores (p = 0.024, d = 0.2), indicating decreased HRQoL. Similar findings were obtained for child‐reported HRQoL. The parent‐reported mental health of the HCTD‐group showed significantly increased Total difficulties sum scores (p = 0.01, d = 0.3), indicating decreased mental health. While the male and female MFS‐ and hEDS‐subgroups both reported decreased HRQoL, only the hEDS‐subgroup reported decreased mental health. In conclusion, children and adolescents with HCTD report decreased HRQoL and mental health, with most adverse outcomes reported in children with hEDS and least in those with MFS. These findings call for systematic monitoring and tailored interventions.

Clinical Characteristics of 100 Patients with Hypermobility Spectrum Disorders and Shoulder Complaints With or Without Mechanical Symptoms: A Cross-Sectional Study

OBJECTIVE

The aims were to describe the clinical characteristics of patients with hypermobility spectrum disorders (HSD) and shoulder complaints with or without mechanical symptoms, and to compare characteristics between these groups.

DESIGN

Descriptive study.

SETTING

Primary care PARTICIPANTS: One-hundred patients with HSD and shoulder complaints for at least three months were included from primary care.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE(S)

Medical history, self-reported (shoulder pain and function, discomfort due to other symptoms, fatigue, fear of movement, quality of life) and objective (strength, range of motion, proprioception) characteristics were collected by physiotherapists. Mechanical symptoms (Yes/No) were defined as self-reported shoulder instability, subluxation, and/or laxity.

RESULTS

Sixty-seven reported mechanical symptoms. Patients in both groups reported impairments related to shoulder pain, function, fatigue, fear of movement, and quality of life. Patients with mechanical symptoms were younger (mean (95% CI): 35.1 (32.3; 37.9) vs. 43.3 (38.4; 48.1) years), had longer symptom duration (median: 46 (36; 66) vs. 24 (9; 56) months), reported a previous shoulder dislocation (25% (16; 37) vs. 3% (0; 16)), experienced that their shoulder was loose (64% (52; 76) vs. 15% (5; 32)), and reported discomfort due to other symptoms (OR 1.48 (1.17; 1.87)). Furthermore, a larger proportion had received supplemental treatment (analgesic medication, steroid injection/surgery).

CONCLUSION(S)

Both groups with HSD and shoulder complaints presented with substantial shoulder-related impairments. Two-thirds reported mechanical symptoms, were younger, and more severely impaired than those without mechanical symptoms. These findings highlight the importance of managing mechanical shoulder symptoms to fully address the patients' impairments.

Considerations for lactation with Ehlers-Danlos syndrome: a narrative review

Background

Ehlers-Danlos syndrome (EDS) is a rare genetic connective tissue condition that is poorly understood in relation to lactation. As diagnostic methods improve, prevalence has increased. EDS, a disorder that impacts connective tissue, is characterized by skin extensibility, joint hypermobility, and fragile tissue which can affect every organ and body system leading to complications during pregnancy, delivery, and the postpartum period. Traits of this disease can cause mild to severe physiologic and functional obstacles during lactation. Unfortunately, there is little clinical evidence and minimal guidance for lactation management, and providers may feel uncomfortable and hesitant to address these concerns with patients due to a lack of readily available resources on the subject and inexperience with such patients. This narrative review describes and discusses the types of EDS, identifying symptoms, considerations, and precautions for care providers to implement during lactation and breastfeeding.

Methods

An electronic search of relevant citations was conducted using the databases Cochrane, PubMed, and Google Scholar from 1 January 2000 to 1 November 2021. Search terms used were Ehlers-Danlos syndrome, Hypermobility Syndrome, breastfeeding, lactation, breastmilk expression, breastmilk collection, human milk expression, human milk collection, and infant feeding. The search of these databases yielded zero results. As no research articles on EDS were directly related to lactation, this narrative review includes articles found that related to the health of mothers relevant to maternal function during lactation.

Discussion

For the healthcare provider, identifying characteristics of EDS can improve the management of lactation challenges. Mothers may experience generalized symptoms from gastrointestinal distress to fatigue or chronic pain, while they also may suffer from more specific joint complaints and injuries, such as dislocations / subluxations, or skin fragility. Such obstacles can generate impediments to breastfeeding and create unique challenges for breastfeeding mothers with EDS.

Unfortunately, new mothers with these symptoms may have them overlooked or not addressed, impacting a mother’s ability to meet her breastfeeding intentions. While there are some published research manuscripts on EDS and pregnancy, there is a lack of information regarding breastfeeding and lactation. Additional research is needed to help guide EDS mothers to achieve their breastfeeding intentions.

Pain in the Ehlers-Danlos syndromes: Mechanisms, models, and challenges

Chronic pain is one of the most common, yet poorly studied, complaints in people suffering from Ehlers-Danlos syndromes (EDS). This heterogeneous group of heritable connective tissue disorders is typically characterized by skin hyperextensibility, joint hypermobility, and generalized connective tissue fragility. Most EDS types are caused by genetic defects that affect connective tissue biosynthesis, thereby compromising collagen biosynthesis or fibrillogenesis and resulting in a disorganized extracellular matrix. Even though chronic pain is a major source of disability, functional impairment, and psychosocial suffering in EDS, currently used analgesics and other treatment strategies provide inadequate pain relief and thus represents an important unmet medical need. An important contributor to this is the lack of knowledge about the underlying mechanisms. In this narrative review, we summarize the current understanding of pain and the associated mechanisms in EDS based on clinical studies focusing on questionnaires and experimental pain testing as well as studies in animal models of EDS. In addition, we highlight the challenges, gaps, and opportunities in EDS-pain research.

Occupational Therapy Interventions for Clients with Ehlers-Danlos Syndrome (EDS) in the Presence of Postural Orthostatic Tachycardia Syndrome (POTS)

Postural orthostatic tachycardia syndrome (POTS) is often seen in clients with Ehlers-Danlos syndrome (EDS), primarily hypermobile EDS. Research has shown clients with EDS and POTS may experience limitations affecting not only their physical function, but also their social, emotional, and mental well-being. Using a client-centered approach, occupational therapy practitioners assess health, well-being, symptomatology (fatigue, muscle pain, dizziness, etc.), participation and engagement in occupation, and provide interventions to improve quality of life. This paper will address occupational therapy interventions to treat common symptomatology for clients with EDS in the presence of POTS, including environmental modifications, use of adaptive equipment and orthoses, exercise and fall prevention, energy conservation and pacing, sleep hygiene, and routine and habit development to promote optimal engagement in meaningful occupations.

Capsulorraphy with Achilles allograft augmentation for shoulder instability in patients with Ehlers-Danlos syndrome

BACKGROUND

Surgical management of shoulder instability in patients with Ehlers-Danlos syndrome (EDS) remains challenging secondary to the pathologic nature of their connective tissue. Allograft reconstruction of the shoulder capsule in EDS has the potential to increase stability by providing healthier connective tissue. The purpose of this study was to report the surgical technique and outcome of open capsulorraphy and augmentation of the anterior capsule with an Achilles tendon allograft in patients with shoulder instability in the setting of EDS.

METHODS

Five shoulders (4 patients) with EDS and severe anteroinferior or multidirectional instability underwent open capsular shift combined with Achilles allograft augmentation of the anterior capsule. Patients were evaluated for pain, motion, recurrent instability, subjective shoulder value, American Shoulder and Elbow Surgeons score, complications, and reoperations. The mean follow-up time was 3.6 years (range, 2-5 years).

RESULTS

Shoulder stability was restored in 4 of 5 (80%) shoulders. At the final follow-up, the mean subjective shoulder value and American Shoulder and Elbow Surgeons scores were 84 and 77.3, respectively. One shoulder developed recurrent posterior instability after an injury 1.6 years after the index procedure. The mean pain visual analog scale was 7 preoperatively and 2 at the most recent follow-up. Before surgery, all patients reported the use of narcotic pain medication, whereas at the most recent follow-up, only the one patient who had experienced recurrence reported moderate pain. Except for the shoulder that required revision surgery for posterior shoulder instability, there were no complications or other reoperations.

CONCLUSION

Open capsulorraphy with Achilles allograft augmentation improved stability and pain in 4 of 5 shoulders with instability in the setting of EDS. In this small case series of patients with EDS, Achilles tendon allograft augmentation was safe and effective as a primary or revision surgical procedure for anterior shoulder instability. A larger patient cohort with longer follow-up is needed to confirm these findings.

The Beighton Score as a measure of generalised joint hypermobility

The Beighton Score (BS) is a set of manoeuvres in a nine-point scoring system, used as the standard method of assessment for Generalised Joint Hypermobility (GJH). It was originally developed as an epidemiological tool used in screening large populations for GJH, but later adopted as a clinical tool for diagnostic purposes. Its ability to truly reflect GJH remains controversial, as joints within the scoring system are predominantly of the upper limb and disregard many of the major joints, preventing a direct identification of GJH. Furthermore, a consistent finding in the literature whereby the BS failed to identify hypermobility in joints outside the scoring system suggests its use as an indirect indicator of GJH is also not viable. As such, the collective findings of this review demonstrate a need for a change in clinical thinking. The BS should not be used as the principle tool to differentiate between localised and generalised hypermobility, nor used alone to exclude the presence of GJH. Greater emphasis should be placed on a clinician’s judgement to identify or exclude GJH, according to its full definition.

A randomised controlled trial of heavy shoulder strengthening exercise in patients with hypermobility spectrum disorder or hypermobile Ehlers-Danlos syndrome and long-lasting shoulder complaints: study protocol for the Shoulder-MOBILEX study

Background

Four out of five patients with hypermobility spectrum disorder (HSD) or hypermobile Ehlers-Danlos syndrome (hEDS) experience shoulder complaints including persistent pain and instability. Evidence suggests that patients with HSD/hEDS who experience knee and back complaints improve with exercise-based therapy. However, no study has focused on exercise-based treatment for the shoulder in this patient group. The potential benefits of strengthening the shoulder muscles, such as increased muscle-tendon stiffness, may be effective for patients with HSD/hEDS who often display decreased strength and increased shoulder laxity/instability.

The primary aim is to investigate the short-term effectiveness of a 16-week progressive heavy shoulder strengthening programme and general advice (HEAVY) compared with low-load training and general advice (LIGHT), on self-reported shoulder symptoms, function, and quality of life.

Methods

A superiority, parallel group, randomised controlled trial will be conducted with 100 patients from primary care with HSD/hEDS and shoulder complaints (persistent pain and/or instability) for more than 3 months. Participants will be randomised to receive HEAVY (full range of motion, high load) or LIGHT (neutral to midrange of motion, low load) strengthening programme three times weekly with exercises targeting scapular and rotator cuff muscles. HEAVY will be supervised twice weekly, and LIGHT three times during the 16 weeks. The primary outcome will be between-group difference in change from baseline to 16-week follow-up in the Western Ontario Shoulder Instability Index (WOSI, 0-2100 better to worse). Secondary outcomes will include a range of self-reported outcomes covering symptoms, function, and quality of life, besides clinical tests for shoulder strength, laxity/instability, and proprioception. Outcome assessors will be blinded to group allocation. Participants will be kept blind to treatment allocation through minimal information about the intervention content and hypotheses. Primary analyses will be performed by a blinded epidemiologist.

Discussion

If effective, the current heavy shoulder strengthening programme will challenge the general understanding of prescribing low-load exercise interventions for patients with HSD/hEDS and provide a new treatment strategy. The study will address an important and severe condition using transparent, detailed, and high-quality methods to potentially support a future implementation.

Surgical Management of Shoulder and Knee Instability in Patients with Ehlers-Danlos Syndrome: Joint Hypermobility Syndrome

Ehlers-Danlos Syndrome (EDS) is a hereditary disorder of the connective tissue, which has been classified into numerous subtypes over the years. EDS is generally characterized by hyperextensible skin, hypermobile joints, and tissue fragility. According to the 2017 International Classification of EDS, 13 subtypes of EDS have been recognized. The majority of genes involved in EDS are either collagen-encoding genes or genes encoding collagen-modifying enzymes. Orthopedic surgeons most commonly encounter patients with the hypermobile type EDS (hEDS), who present with signs and symptoms of hypermobility and/or instability in one or more joints. Patients with joint hypermobility syndrome (JHS) might also present with similar symptomatology. This article will focus on the surgical management of patients with knee or shoulder abnormalities related to hEDS/JHS.

Exploring the underlying mechanism of pain-related disability in hypermobile adolescents with chronic musculoskeletal pain

OBJECTIVES

A significant proportion of adolescents with chronic musculoskeletal pain (CMP) experience difficulties in physical functioning, mood and social functioning, contributing to diminished quality of life. Generalized joint hypermobility (GJH) is a risk factor for developing CMP with a striking 35-48% of patients with CMP reporting GJH. In case GJH occurs with one or more musculoskeletal manifestations such as chronic pain, trauma, disturbed proprioception and joint instability, it is referred to as generalized hypermobility spectrum disorder (G-HSD). Similar characteristics have been reported in children and adolescents with the hypermobile Ehlers-Danlos Syndrome (hEDS). In the management of CMP, a biopsychosocial approach is recommended as several studies have confirmed the impact of psychosocial factors in the development and maintenance of CMP. The fear-avoidance model (FAM) is a cognitive-behavioural framework that describes the role of pain-related fear as a determinant of CMP-related disability.

CONTENT

Pubmed was used to identify existing relevant literature focussing on chronic musculoskeletal pain, generalized joint hypermobility, pain-related fear and disability. Relevant articles were cross-referenced to identify articles possibly missed during the primary screening. In this paper the current state of scientific evidence is presented for each individual component of the FAM in hypermobile adolescents with and without CMP. Based on this overview, the FAM is proposed explaining a possible underlying mechanism in the relations between GJH, pain-related fear and disability.

SUMMARY AND OUTLOOK

It is assumed that GJH seems to make you more vulnerable for injury and experiencing more frequent musculoskeletal pain. But in addition, a vulnerability for heightened pain-related fear is proposed as an underlying mechanism explaining the relationship between GJH and disability. Further scientific confirmation of this applied FAM is warranted to further unravel the underlying mechanism.In explaining disability in individuals with G-HSD/hEDS, it is important to focus on both the physical components related to joint hypermobility, in tandem with the psychological components such as pain-related fear, catastrophizing thoughts and generalized anxiety.

The Ehlers-Danlos syndromes

The Ehlers-Danlos syndromes (EDS) are a heterogeneous group of hereditary disorders of connective tissue, with common features including joint hypermobility, soft and hyperextensible skin, abnormal wound healing and easy bruising. Fourteen different types of EDS are recognized, of which the molecular cause is known for 13 types. These types are caused by variants in 20 different genes, the majority of which encode the fibrillar collagen types I, III and V, modifying or processing enzymes for those proteins, and enzymes that can modify glycosaminoglycan chains of proteoglycans. For the hypermobile type of EDS, the molecular underpinnings remain unknown. As connective tissue is ubiquitously distributed throughout the body, manifestations of the different types of EDS are present, to varying degrees, in virtually every organ system. This can make these disorders particularly challenging to diagnose and manage. Management consists of a care team responsible for surveillance of major and organ-specific complications (for example, arterial aneurysm and dissection), integrated physical medicine and rehabilitation. No specific medical or genetic therapies are available for any type of EDS.

Heavy shoulder strengthening exercise in people with hypermobility spectrum disorder (HSD) and long-lasting shoulder symptoms: a feasibility study

Background

People with hypermobility spectrum disorder (HSD) are in great risk of experiencing shoulder symptoms, but evidence for treatment is sparse. Therefore, the objective was to evaluate the feasibility of 16-week shoulder strengthening programme for improving shoulder strength and function in people with HSD and shoulder symptoms for more than 3 months to inform a future randomised controlled trial (RCT).

Methods

Twelve participants (11 females, 39.3 ± 13.9 years) with HSD and shoulder instability and/or pain for more than 3 months underwent a 16-week heavy shoulder strengthening exercise programme three times weekly using exercises targeting scapular and rotator cuff muscles. Primary outcomes were pre-defined research progression criteria including recruitment rate (acceptable, 6 participants/month), assessment duration (acceptable: < 120 min), participant retention (acceptable: > 80% complete intervention), training adherence (acceptable: > 75% adhere to > 36 training sessions) and adverse events (acceptable: minor events with no participants discontinuing the study), besides participant and physiotherapist feedback. Secondary treatment outcomes were assessed using the Western Ontario Shoulder Instability Index (WOSI, 0–2100 better to worse), self-reported pain, kinesiophobia and fatigue, isometric shoulder strength, besides clinical tests for instability, hypermobility, laxity, and proprioception.

Results

Recruitment rate was 5.6/month, assessment duration (mean ± SD) 105 ± 9 min, retention 100%, adherence 83%, and four participants experienced short-lasting soreness or pain. Participant feedback was positive, and physiotherapists found the intervention relevant and applicable to the population. The WOSI total score showed an improvement by 51% (mean ± SD, points: baseline 1037 ± 215; Follow up 509 ± 365; mean change (95% CI), − 528 (− 738, − 318)), and participants reported reduced pain, kinesiophobia and fatigue. Shoulder strength measurements improved by 28–31% (mean change (95% CI), Nm/kg: scaption 0.51 (0.23, 0.78); internal rotation 1.32 (0.70, 1.95) and external rotation 0.89 (0.37, 1.40)), and clinical tests indicated decreased shoulder laxity/instability.

Conclusions

The shoulder strengthening exercise programme was feasible and safe for people with HSD and long-lasting shoulder symptoms. A future RCT, with an improved recruitment strategy, will demonstrate whether the exercise programme is also effective in improving symptoms and muscle-tendon function in this population.

Subacromial space outlet in female patients with multidirectional instability based on hypermobile Ehlers-Danlos syndrome and hypermobility spectrum disorder measured by ultrasound

OBJECTIVE

The objective of the study was to compare the acromiohumeral distance (AHD) between patients diagnosed with hypermobility type of the Ehlers-Danlos syndrome (hEDS) or hypermobility spectrum disorder (HSD) and healthy controls by evaluating the relative amount the tendon occupies in the subacromial area. Furthermore, the aim was to evaluate if there was a change in AHD with arm elevation within and between groups.

METHODS

Twenty-nine female patients with hEDS/HSD (aged 34 ± 12.9 years) and 20 healthy controls (aged 33 ± 10.8 years) participated in the study. The supraspinatus tendon (SST) thickness and AHD were measured using ultrasound. The interplay between the SST and the AHD was expressed as the occupation ratio (OcAHD), calculated as the SST thickness as a percentage of AHD. The measures were performed in the resting position and in subsequently 45° and 60° of active arm elevation in the scapular plane.

RESULTS

The main finding is that patients with hEDS/HSD have a larger subacromial space outlet compared with the controls when measured by ultrasound. Furthermore, in both groups, we found an increased OcAHD during active arm elevation compared with the resting position, which indicates that similar mechanisms occur for patients with hEDS/HSD and healthy controls.

CONCLUSION

Patients with hEDS/HSD have a larger available subacromial space outlet compared with healthy individuals. OcAHD increased during active arm elevation compared with the resting position in both groups. This knowledge is important when designing rehabilitation exercise programs for shoulder instability patients with abnormal glenohumeral biomechanics.

The relationship between joint hypermobility and subacromial impingement syndrome and adhesive capsulitis of the shoulder

OBJECTIVE:

Joint hypermobility (JH) is a clinical condition in which the joints move beyond the expected physiological range of motion. JH can be accompanied by many musculoskeletal complaints. One of the common causes of musculoskeletal pain is shoulder pain. The aim of this study was to investigate the relationship between subacromial impingement syndrome (SAIS), shoulder adhesive capsulitis (AC), and JH in patients with shoulder pain.

METHODS:

Patients aged between 18 and 70 years who presented at the physical medicine and rehabilitation outpatient clinic and who were diagnosed with SAIS or AC in a clinical and physical examination were included in the study. Patients in the same age group without musculoskeletal system pain were included in a control group. All of the cases were assessed for hypermobility using the Beighton score for generalized joint hypermobility (GJH), and the revised 1998 Brighton criteria for benign joint hypermobility syndrome (BJHS).

RESULTS:

Of the 124 cases included in the study, 71 (57.3%) were female and 53 (42.7%) were male. There was no case of GJH in the AC group. There were 2 (4.50%) cases in the SAIS group and 3 (7.5%) in the control group. BJHS was found in 4 (10%) cases in the AC group, 6 (13.63%) in the SAIS group, and 2 (5%) cases in the control group. There was no statistically significant difference between groups in terms of JH (p>0.05). The Beighton scores of the AC group were statistically lower those of the control group (p<0.05).

CONCLUSION:

The results of this study indicated no significant difference between the SAIS group, the AC group, and the control group in terms of GJH and BJHS. The fact that Beighton scores were lower in the AC group than in the control group suggests that the probability of developing AC in those with JH may be lower.

Management of chronic pain in Ehlers-Danlos syndrome: Two case reports and a review of literature

RATIONALE

Ehlers-Danlos syndromes (EDSs) are a heterogeneous group of heritable connective tissue disorders involving defective collagen synthesis. Patients with EDS are prone for chronic myofascial pain, apart from other comorbidities. Although the initial pathology is commonly nociceptive, progression of EDS leads to neuropathies and central sensitization of pain signals. Overall, approximately 90% or more EDS patients suffer from chronic pain. There are no existing guidelines to manage chronic pain in EDS patients. In this article, we illustrate 2 case reports of EDS patients with chronic pain and review the relevant literature regarding the pathological considerations and management of chronic pain in EDS.

PATIENT CONCERNS

Our first patient had worsening multiple joint pains despite treatment with medications and a recent diagnosis of EDS-type 3. The second patient had a complicated history including longstanding EDS and multiple previous surgeries. She was referred due to concern about complex regional pain syndrome (CRPS) in her upper extremity.

DIAGNOSES

For the first patient, apart from chronic pain due to her EDS, her history also revealed that she suffered from kinesiophobia. For the second patient, a detailed clinical assessment revealed no signs of CRPS but instead a generalized worsening of EDS symptoms.

INTERVENTIONS

Both patients were evaluated by the multidisciplinary team consisting of a pain physician, nurse, pain psychologist, and a kinesiologist. Their treatment involved optimization of daily medications, participation in pain self-management sessions that included cognitive behavioral therapy, graded exercises, coping, and relaxation strategies.

OUTCOMES

Both patients demonstrated significantly better pain control and achieved overall improvement in daily living.

LESSONS

EDS is a complex illness with a multitude of symptoms. As in our patients, EDS patients also suffer from panic and anxiety disorders that increase the burden of pain. Apart from optimization of medications, EDS patients are best managed by a multidisciplinary approach that includes pain education and life style changes. The caution that they are resistant to local anesthetics is unwarranted. Appropriate pain interventions in selected patients may have a role to decrease pain intensity.

Identification of a de novo case of COL5A1-related Ehlers-Danlos syndrome in an infant in the West Indies leading to improved targeted clinical care

A 1-year-old girl from an underserved community presented with irritability, pain, and delayed motor skills. Our genetics outreach program facilitated the diagnosis of Ehlers-Danlos syndrome masquerading as developmental delay after noting hyperextensible skin. Diagnosis for this family allows for state-of-the-art cardiac monitoring and appropriate symptomatic treatment for this rare disease.

Diagnosis of Ehlers-Danlos syndrome after a first shoulder dislocation

BACKGROUND

Shoulder dislocation is often the first symptom of Ehlers-Danlos syndrome (EDS). Whether it occurs in early-onset EDS is unknown. In most cases, surgical failure leads to the diagnosis. We aimed to determine whether clinical symptoms can signal the presence of EDS at a first dislocation.

MATERIALS AND METHODS

In this retrospective study, we analyzed clinical and radiologic data for 27 patients with EDS and shoulder instability and a control population of 40 consecutive non-EDS patients undergoing surgery for an unstable shoulder. Data were collected on gender, age, single or bilateral disease, general hyperlaxity, shoulder hyperlaxity, number of dislocations or subluxations, nontraumatic onset, and pain specificity. Nerve and vascular injuries, joint disorders, and family history were recorded, and radiologic data were reported.

RESULTS

Age <14 years, female sex, bilateral disorder, and general hyperlaxity were significantly more frequent in patients with EDS and a first dislocation than in those without EDS. Painless dislocation with pain after dislocation and concomitant nerve injury were more frequent in affected patients, as were hemostasis disorders and a family history of joint hyperlaxity. Bone lesions were not seen on radiographs. Only the hyperlaxity sign (external rotation >85°) did not differ between the groups.

CONCLUSION

After a first dislocation in a young girl with global hyperlaxity but not necessarily shoulder hyperlaxity, painless atraumatic dislocation with pain after reduction can suggest EDS.

The Effect of Shoulder Muscle Fatigue on Acromiohumeral Distance and Scapular Dyskinesis in Women With Generalized Joint Hypermobility

Muscle fatigue is considered to be one cause of shoulder pain, and subjects with generalized joint hypermobility (GJH) are affected more by shoulder pain. The purpose of this study was to examine the effects of muscle fatigue on acromiohumeral distance (AHD) and scapular dyskinesis in women with GJH. Thirty-six asymptomatic participants were assigned to either a GJH (n = 20) or control group (n = 16) using the Beighton scale. Before and after elevation fatigue trials, AHD was measured with ultrasonography at rest and when the arm was in 90° active elevation. A scapular dyskinesis test was used to visually observe alterations in scapular movement. Our results showed that in both groups, the fatigue reduced AHD in the 90° elevation position and increased the presence of scapular dyskinesis; however, no differences were found between the two groups. Although GJH has been identified as a factor for developing musculoskeletal disorders, generalized joint hypermobility did not result in changes to scapular dyskinesis or AHD, even after an elevation fatigue task. More studies are needed to evaluate the effects of muscle fatigue in subjects with GJH and a history of shoulder instability.

Generalised joint hypermobility and shoulder joint hypermobility, - risk of upper body musculoskeletal symptoms and reduced quality of life in the general population

Background

Generalised Joint Hypermobility (GJH) is a hereditary condition with an ability to exceed the joints beyond the normal range. The prevalence of GJH in the adult population and its impact on upper body musculoskeletal health and quality of life has mostly been studied in selected populations. The aims of this study were therefore, firstly to study the prevalence of GJH and GJH including shoulder hypermobility (GJHS), in the general Danish adult population; secondly to test the associations between GJH or GJHS and upper body musculoskeletal symptoms and health-related quality of life (HRQoL).

Methods

The study was cross-sectional where 2072 participants, aged 25–65, randomly extracted from the Danish Civil Registration System), were invited to answer a questionnaire battery (Five-Part Questionnaire for classification of GJH, Standardised Nordic Questionnaire for musculoskeletal symptoms, EuroQoL-5D for HRQoL).

Results

Totally 1006 (49%) participants responded. The prevalence of GJH and GJHS were 30% (n = 300) and 5% (n = 51), respectively. Compared with Non GJH (NGJH), participants with GJH and GJHS had Odds Ratio (OR) of 1.5-3.5 for upper body musculoskeletal symptoms within the last 12 months (mostly shoulders and hands/wrists). GJH and GJHS also had OR 1.6–4.4 for being prevented from usual activities, mostly due to shoulder and neck symptoms. Furthermore, GJH and GJHS had OR 2.2–3.1 for upper body musculoskeletal symptoms lasting for more than 90 days (neck, shoulders, hand/wrists), and 1.5–3.5 for reduced HRQoL (all dimensions, but anxiety/depression) compared with NGJH. Generally, most OR for GJHS were about twice as high as for those having GJH alone.

Conclusions

GJH and GJHS are frequently self-reported musculoskeletal conditions in the Danish adult population. Compared with NGJH, GJH and especially GJHS, present with higher OR for upper body musculoskeletal symptoms, more severe symptoms and decreased HRQoL.

Hypermobile Ehlers-Danlos syndrome (a.k.a. Ehlers-Danlos syndrome Type III and Ehlers-Danlos syndrome hypermobility type): Clinical description and natural history

The hypermobile type of Ehlers-Danlos syndrome (hEDS) is likely the most common hereditary disorder of connective tissue. It has been described largely in those with musculoskeletal complaints including joint hypermobility, joint subluxations/dislocations, as well as skin and soft tissue manifestations. Many patients report activity-related pain and some go on to have daily pain. Two undifferentiated syndromes have been used to describe these manifestations-joint hypermobility syndrome and hEDS. Both are clinical diagnoses in the absence of other causation. Current medical literature further complicates differentiation and describes multiple associated symptoms and disorders. The current EDS nosology combines these two entities into the hypermobile type of EDS. Herein, we review and summarize the literature as a better clinical description of this type of connective tissue disorder. © 2017 Wiley Periodicals, Inc.

Differentiating lipedema and Dercum's disease

BACKGROUND

People with lipedema or Dercum's disease (DD) can have a similar distribution of excess painful nodular subcutaneous adipose tissue (SAT), making them difficult to differentiate.

METHODS

Case series of 94 patients with DD, 160 with lipedema and 18 with both diagnoses (Lip+DD) from a single clinic in an academic medical center to improve identification and differentiation of these disorders by comparison of clinical findings, prevalence of type 2 diabetes (DM2), hypermobility by the Beighton score and assessment of a marker of inflammation, Total complement activity (CH50).

RESULTS

Differences between groups were by Student's t-test with α of 0.05. The Lipedema Group had significantly greater weight, body mass index (BMI), gynoid distributed nodular SAT and fibrotic and heavy tissue than the DD Group. Hypermobility was significantly higher in the Lipedema (58±0.5%) than DD Group (23±0.4%; P<0.0001). DM2 was significantly greater in the DD (16±0.2%; P=0.0007) than the Lipedema Group (6±0.2%). Average pain by an analog scale was significantly higher in the DD (6±2.5%) than the Lipedema Group (4±2.1%; P<0.0001). Fatigue and swelling were common in both groups. Easy bruising was more common in the Lipedema Group, whereas abdominal pain, shortness of breath, fibromyalgia, migraines and lipomas were more prevalent in the DD Group. The percentage of patients with elevated CH50 was significantly positive in both groups.

CONCLUSIONS

The significantly lower prevalence of DM2 in people with lipedema compared with DD may be due to the greater amount of gynoid fat known to be protective against metabolic disorders. The high percentage of hypermobility in lipedema patients indicates that it may be a comorbid condition. The location of fat, high average daily pain, presence of lipomas and comorbid painful disorders in DD patients may help differentiate from lipedema.
