Quality of life prediction in children with joint hypermobility syndrome

The Spider: a visual, multisystemic symptom impact questionnaire for people with hypermobility-related disorders-validation in adults

INTRODUCTION

Hypermobility spectrum disorders (HSD) and hypermobile Ehlers-Danlos syndrome (hEDS) are often accompanied by varied and complex multisystemic comorbid symptoms/conditions. The Spider questionnaire was developed to evaluate the presence and impact of eight common multisystemic comorbidities. Thirty-one questions across eight symptom domains assess neuromusculoskeletal, pain, fatigue, cardiac dysautonomia, urogenital, gastrointestinal, anxiety, and depression symptoms. This study aimed to evaluate the Spider's construct validity in adults.

METHOD

A cross-sectional observational study was conducted over four stages. Three international patient charities aided recruitment of participants through social media and website advertisements. Adults aged 18 to 65 years, with and without HSD/hEDS, were invited to participate. Validated, frequently used comparator questionnaires were used to establish convergent validity of Spider symptom domains. A control group was recruited for known-group validity analysis. Participants answered each Spider domain and the corresponding comparator questionnaire via surveys hosted by REDCap. Anonymous data were analysed using SPSS. Convergent validity was assessed through Spearman's correlational analysis and known-group validity through Mann-Whitney U analysis.

RESULTS

A total of 11,151 participants were recruited across the four stages. Statistically significant, moderate-to-strong correlations were found between all Spider domains and their comparators (p < 0.001, r = 0.63 to 0.80). Known-group validity analysis showed statistically significant differences (p < 0.001) between the hypermobile and control groups in all eight domains.

CONCLUSIONS

Convergent and known-group validity of the Spider was established with adults. These results suggest the Spider can measure the presence and impact of multisystemic comorbid symptoms/conditions in adults with HSD/hEDS, providing a tool which guides multidisciplinary management. Key Points • The Spider questionnaire is a novel tool assessing the presence and impact of the multisystemic comorbid symptoms/conditions associated with HSD/hEDS. • Convergent and known-group validity of the Spider questionnaire was established in adults aged 18 to 65. • This tool provides a quick and easy method to visualise the symptom profile of those with HSD/hEDS to guide symptom management.

The centrality of healthcare and education interactions - An Interpretive Phenomenological Analysis of experiences of parents of children with Ehlers-Danlos Syndrome

BACKGROUND

Ehlers-Danlos Syndrome (EDS) is a rare group of connective tissue disorders and, as such, the diagnosis can often be delayed. While emerging research indicates that there may be adverse psychosocial consequences for the child, little is known about the processes behind such outcomes, including the psychosocial impact of this rare disease on family life.

AIMS

To extend our understanding, we examined the lived experiences of parenting a child with EDS.

METHODS

Four parents recruited from a specialist child development clinic participated in semi-structured interviews. Data were analysed using Interpretative Phenomenological Analysis RESULTS: Three superordinate themes were identified: (1) Challenges Associated with hEDS, (2) Interactions with Professionals and (3) "Pulling and Pacing": Life with EDS.

DISCUSSION

This is one of the first qualitative studies to gain an insight into the lived experiences of parenting a child with EDS. Findings had systemic implications. Specifically, we demonstrate the need for raising awareness in health and educational professionals about how to better support families to support the child, as well as the importance of promoting effective advocacy skills in parents.

Pre-Rheumatology Referral Consultation and Investigation Pattern in Children with Joint Complaints: Focus on Juvenile Idiopathic Arthritis

The diagnosis of juvenile idiopathic arthritis (JIA) is often entrusted to the pediatric rheumatologist specialist. Timely referral to a specialized center is crucial. This study aims to assess the consultation and investigation patterns of patients with joint complaints before rheumatology referral. This longitudinal cohort study included patients with joint complaints who were referred to the Pediatric Rheumatology Unit. The cohort included 301 patients (58% female), 50 of them (17%) diagnosed with JIA. Compared to patients with orthopedic conditions or functional diseases, JIA patients had seen more specialists (p < 0.01) and received a quicker diagnosis (p < 0.01). Patients with early JIA diagnosis (within 3 months from symptoms onset) were younger (8.46 vs. 11.5 years old; p = 0.04), more frequently female (78% vs. 47%, p = 0.03), and with higher erythrocyte sedimentation rate (ESR) values (37 vs. 9 mm/h; p = 0.02) than those diagnosed later. Patients with a late diagnosis of JIA had a significantly longer median time between the first healthcare visit and the PR referral (25 vs. 101 days; p < 0.01). The main contributor to diagnostic delay in JIA was the time required for PR referral after the first healthcare consult. Younger age, female sex, and higher ESR values were associated with earlier diagnosis of JIA.

Physical therapy interventions in generalized hypermobility spectrum disorder and hypermobile Ehlers-Danlos syndrome: a scoping review

PURPOSE

Physical therapy (PT) plays a central role in treating individuals with Generalized Hypermobility Spectrum Disorder (G-HSD) and Hypermobile Ehlers-Danlos Syndrome (hEDS). However, there is limited research describing these individuals' PT management. This review aims to systematically map the evidence on PT interventions to treat this patient population.

METHODS

A systematic literature search of PubMed, CINAHL, and Embase from January 2000 to April 2023 was performed. After the screening process, studies were appraised and classified based on the type of PT interventions used. Five reviewers independently assessed the articles.

RESULTS

The search produced 757 articles. Twenty-eight met the inclusion criteria. The studies included 630 participants, mostly female, with a mean age of 26.2 (ranging from 2 to 69). The PT interventions used were therapeutic exercise, patient instruction, motor function training, adaptive equipment, manual therapy, and functional training.

CONCLUSIONS

The evidence indicates that therapeutic exercise and motor function training are efficacious methods to treat individuals with G-HSD and hEDS. There is also weak evidence for using adaptive equipment, patient instruction, manual therapy, and functional training. Recent studies emphasize multidisciplinary care and understanding of the psychological impact of G-HSD/hEDS. Additional research is needed to determine the effectiveness and dosage of PT interventions.

The Impact of Podiatric Intervention on the Quality of Life and Pain in Children and Adolescents with Hypermobility

The purpose of this study was to evaluate the effect of custom-made orthotics on pain, health-related quality of life (HRQoL), function and fatigue in children and adolescents with generalised joint hypermobility (GJH) and lower limb pain. Fifty-three children aged 5-18 years were fitted with custom-made polypropylene orthotics. Visual analogue scale (VAS) assessed lower limb pain severity, Paediatric Quality of Life Inventory assessed HRQoL and fatigue and six-minute walk test (6 MWT) measured functional endurance at baseline, at 1 month and 3 months post-intervention. A mixed model including a random intercept for participant and a fixed effect for time was used to assess differences in outcomes over time. Fifty-two children completed the study (mean age 10.6-years). Children reported significantly reduced pain (mean VAS reduction -27/100, 95%CI: -33, -21), improved HRQoL (mean total improvement 11/100, 95%CI: 7, -15), functional capacity (mean 6MWT improvement 27 m, 95%CI: 18, -36) and fatigue (mean total improvement 13/100, 95%CI: 9, -17) after 1 month of wearing the custom-made orthotics. From 1 month to 3 months there was further statistically but not clinically significant reduction in pain while benefit on other outcomes was maintained. In this study, children with GJH reported reduced lower limb pain, improved HRQoL, functional endurance and fatigue after a month post-fitting of custom-made orthotics which was maintained over a 3 month period. Orthotics were well-tolerated with no serious adverse events reported.

The Effectiveness of Compression Garments for Reducing Pain in Non-Vascular Ehlers-Danlos Syndromes: A Prospective Observational Cohort Study

Patients with Ehlers-Danlos Syndrome (EDS) frequently suffer from severe chronic pain. We carried out an observational cohort study to assess the effectiveness of compression garments (CGs) for reducing this pain. Patients with non-vascular EDS were given custom-made Cerecare^® CGs during a visit to a specialist clinic (visit V0). They were followed up over 2 years with visits every 6 months (V1-V4). At each visit, pain was assessed for the joints treated with CGs using a visual analogue scale (VAS; 0-100 mm). Additional measures were obtained to assess neuropathic pain (painDETECT questionnaire), proprioception/balance (Berg Balance Scale), and functional independence, amongst others. Data were analyzed for 67 patients with EDS (hypermobile: 91%; classical: 6%; kyphoscoliotic: 3%). For the most painful joint, the mean VAS rating was 71.5 ± 22.8 mm at V0; this decreased to 53.5 ± 25.5 mm at V1 and 45.7 ± 29 mm at V4 (t-tests: p < 0.0001). From V0 to V4, improvements were also seen for pain at the other joints, neuropathic pain, functional independence, proprioception/balance, and the incidence of sprains and dislocations/subluxations, although not all comparisons were statistically significant (p < 0.05 level). These results indicate that CGs may effectively reduce the pain and joint instability in non-vascular EDS patients.

Hypermobility prevalence, measurements, and outcomes in childhood, adolescence, and emerging adulthood: a systematic review

General Joint Hypermobility (GJH) is a common condition found in 2-57% of the population. Of those with GJH, 10% suffer from accompanying physical and/or psychological symptoms. While the understanding of GJH in the general population is unfolding, its implication in a cohort of children, adolescents and young adults are not yet understood. This systematic review explored GJH's prevalence, tools to measure it, its physical and psychosocial symptoms, with a special interest in aesthetic sports. The CINHAL, MEDLINE, PsycINFO, SPORTDiscus and Scopus databases were searched for relevant studies. Inclusion criteria were (1) Age range of 5-24; (2) Participants had GJH; (3) A measurement for GJH; (4) Studies written in English language. Study screening for title, abstract and full text (when needed) and quality assessment were performed by two independent individuals. 107 studies were included in this review and were thematically grouped into six clusters expressing different foci: (1) GJH's Core Characteristics; (2) Orthopedic; (3) Physical Other; (4) Psychosocial; (5) Treatment and (6) Aesthetic Sports. The review revealed a growing interest in GJH in this cohort in the last decade, especially regarding non-musculoskeletal physical implications and psychosocial aspects. Prevalence varied between different ethnic groups and as a parameter of age, gender and measurement. The most widespread tool to measure GJH was the Beighton scale, with a cut-off varying between 4 and 7. Children show fewer, but similar GJH implication to those in the general population, however, more research on the topic is warranted, especially regarding psychosocial aspects and treatment.

Pediatric joint hypermobility: a diagnostic framework and narrative review

BACKGROUND

Hypermobile Ehlers-Danlos syndrome (hEDS) and hypermobility spectrum disorders (HSD) are debilitating conditions. Diagnosis is currently clinical in the absence of biomarkers, and criteria developed for adults are difficult to use in children and biologically immature adolescents. Generalized joint hypermobility (GJH) is a prerequisite for hEDS and generalized HSD. Current literature identifies a large proportion of children as hypermobile using a Beighton score ≥ 4 or 5/9, the cut off for GJH in adults. Other phenotypic features from the 2017 hEDS criteria can arise over time. Finally, many comorbidities described in hEDS/HSD are also seen in the general pediatric and adolescent population. Therefore, pediatric specific criteria are needed. The Paediatric Working Group of the International Consortium on EDS and HSD has developed a pediatric diagnostic framework presented here. The work was informed by a review of the published evidence.

OBSERVATIONS

The framework has 4 components, GJH, skin and tissue abnormalities, musculoskeletal complications, and core comorbidities. A Beighton score of ≥ 6/9 best identifies children with GJH at 2 standard deviations above average, based on published general population data. Skin and soft tissue changes include soft skin, stretchy skin, atrophic scars, stretch marks, piezogenic papules, and recurrent hernias. Two symptomatic groups were agreed: musculoskeletal and systemic. Emerging comorbid relationships are discussed. The framework generates 8 subgroups, 4 pediatric GJH, and 4 pediatric generalized hypermobility spectrum disorders. hEDS is reserved for biologically mature adolescents who meet the 2017 criteria, which also covers even rarer types of Ehlers-Danlos syndrome at any age.

CONCLUSIONS

This framework allows hypermobile children to be categorized into a group describing their phenotypic and symptomatic presentation. It clarifies the recommendation that comorbidities should be defined using their current internationally accepted frameworks. This provides a foundation for improving clinical care and research quality in this population.

Conservative management of hand impairment in children and adolescents with heritable disorders of connective tissue: A scoping review

AIMS

To synthesize and critically appraise available interventions in the conservative management of hand impairment for children and adolescents with heritable disorders of connective tissue (HDCT).

METHODS

A search of peer-reviewed literature and online platforms were included with data regarding hand impairment and function, conservative management and outcome measures extracted and appraised. Levels of evidence were applied to published literature.

RESULTS

Ten peer-reviewed papers, eleven webpages and YouTube videos met the inclusion criteria. Reported interventions included: strengthening, orthoses, assistive equipment, education and pacing. Evidence of intervention effectiveness and evidence-based guidance on dosage were absent, with no consistency of outcome measures monitoring intervention effectiveness. Online platforms posted by health professionals predominantly provided advice for families without clinical detail of interventions.

CONCLUSIONS

There is a consistent suite of interventions identified in both peer-reviewed literature and online platforms used by clinicians and families to manage hand impairment for children and adolescents with HDCT. Clear dosage parameters and outcome measures are needed in future intervention studies to determine the effectiveness of interventions and guide clinicians in how best to treat hand impairment. Increasing accountability and quality of online resources posted by health professionals for families is warranted to ensure dosage details and precautions are provided.

Pain in Ehlers-Danlos Syndrome: A Non-Diagnostic Disabling Symptom?

BACKGROUND

Ehlers-Danlos syndrome (EDS) is a phenotypically and genetically heterogeneous group of connective tissue disorders. Currently, diagnosis of EDS is based on a series of clinical and genetic tools. On the other hand, the hypermobile form has not yet been characterized from a genetic point of view: it is considered a part of a continuous spectrum of phenotypes, ranging from isolated non syndromic joint hypermobility, through to the recently defined hypermobility spectrum disorders (HSD). The aim of this study is to characterize the pain symptom that is not considered among the diagnostic criteria but is relevant to what concerns the quality of life of patients with EDS. (2) Methods: A review of the literature was performed on two medical electronic databases (PubMed and Embase) on 20 December 2022. Study selection and data extraction were achieved independently by two authors and the following inclusion criteria were determined a priori: published in the English language and published between 2000 and 2022. (3) Results: There were fifty eligible studies obtained at the end of the search and screen process. Pain is one of the most common symptoms found in Ehlers-Danlos (ED) patients. Different causes seem to be recognized in different phases of the syndrome. (4) Conclusions: Pain is a nonspecific symptom and cannot be considered among the diagnostic criteria, but it is a negative predictive factor in the quality of life of patients with EDS. Therefore, proper evaluation and treatment is mandatory.

What are the most important symptoms to assess in hypermobile Ehlers-Danlos syndrome? A questionnaire study based on the Delphi technique

PURPOSE

This study aims to determine from questionnaires, submitted to patients with Ehlers-Danlos syndrome hypermobile type (hEDS), what symptoms they perceive as having the most impact on their well-being and, according to them, what symptoms should be assessed.

MATERIALS AND METHODS

Three rounds of online questionnaires were conducted following the Delphi method. The first round allowed us to obtain the most important symptoms to assess according to the patients. The second and third round aimed at ranking the categories according to their order of importance. Establishment of a consensus was evaluated using Kendall's coefficient of concordance.

RESULTS

A total of 118 responses were analyzed for the first round and 87 for the second and the third round. Ten categories were extracted from the first round. Ranking of the 10 categories in the second round did not reach consensus (W = 0.33, p < 0.001) nor did the four most important categories in the third round (W = 0.43, p < 0.001). However, three categories stand out from ranking: "pain", "fatigue and sleep disorders", and "musculoskeletal disorders".

CONCLUSIONS

These categories seem to be the most important to assess in patients with hEDS, despite the lack of consensus on this ranking.Implications for rehabilitationPain, fatigue and sleep disorders, and musculoskeletal disorders should be given high consideration in the assessment of patients with hypermobile Ehlers-Danlos syndrome (EDS).The high phenotypic variability in the hypermobile EDS requires individualized assessment for each patient and a multidisciplinary approach.

Hand Impairment and Function in Children and Adolescents With Heritable Disorders of Connective Tissue

Importance: Heritable disorders of connective tissue (HDCTs) affect hand function and participation in daily activities for children and adolescents.

Objective: To describe hand impairment and function and determine the extent to which hand impairment and function explain the variation in self-reported functional performance.

Design: Cross-sectional observational study.

Setting: Specialist tertiary hospital.

Participants: Children and adolescents ages 8–18 yr with HDCTs (N = 73).

Intervention: None.

Outcomes and Measures: Hand function outcomes included grip strength (digital dynamometer), manipulation and dexterity (Functional Dexterity Test, Nine-Hole Peg Test), and fine motor skills (Bruininks–Oseretsky Test of Motor Proficiency). Upper limb hypermobility was assessed using the Upper Limb Hypermobility Assessment Tool. Hand pain and fatigue were recorded for a timed button test and 3- and 9-min handwriting tasks. Functional performance was measured using the Childhood Health Assessment Questionnaire.

Results: Scores on all hand function measures were below expected norms. Pain and fatigue were significantly worse after the writing tasks (p &lt; .001) but not the button test (p &gt; .40). Secondary students had significantly lower handwriting scores than primary students (p = .03) but similar grip strength z scores (p = .95). Variation in self-reported functional performance was explained by grip strength (6%) and upper limb hypermobility and dexterity (16%).

Conclusions and Relevance: Young people with HDCTs have poor hand function attributable to poor grip strength and hand pain and fatigue. Comprehensive upper limb evaluation and ongoing monitoring throughout the school years are warranted to inform timely intervention.

What This Article Adds: Children and adolescents with heritable disorders of connective tissue have difficulty with hand function that affect their participation in daily activities. The results of this study can help clinicians identify, assess, and monitor daily activities, performance skills, and symptoms of children and adolescents with HDCTs to promote their participation in all aspects of daily life.

Agreement between parent-proxy and child self-report in pediatric hypermobile Ehlers-Danlos syndrome

Hypermobile Ehlers-Danlos syndrome (hEDS) is a common disorder in children and adolescents that negatively impacts health-related quality of life (HRQOL). It can include chronic pain, fatigue, autonomic dysfunction, and mood problems. The objective of this study was to examine levels of agreement between children and parents in the setting of hEDS and HRQOL. Individuals with hEDS, ages 10-20 years, and their parents were recruited to complete a series of surveys. Instruments included pediatric quality of life generic and multidimensional fatigue scales, Functional Disability Index, Pain-Frequency-Severity-Duration scale, Brief Illness Perception Questionnaire, and Herth Hope Index. Agreement on each measure was evaluated using statistical calculations. Thirty-six parent-child dyads completed the surveys. There were no significant differences between the means of parent and child scores. There was moderate to strong agreement on all survey scores. However, the proportion of dyads with disagreement was relatively high for each individual score. Eighteen dyads disagreed on at least half of the surveys. Body mass index centile and child perception of cognitive fatigue most strongly predicted disagreement in total HRQOL score. Proxy-reporters for children and adolescents with hEDS may agree with their child on average. However, due to significant frequency of clinically important disagreement, information from both children and their parents should be sought whenever possible.

Ankle Joint Dorsiflexion Reference Values in Non-Injured Youth Federated Basketball Players: A Cross-Sectional Study

(1) Background: The aim of the present study was to establish ankle joint dorsiflexion reference values among youth federated basketball players. (2) Methods: Cross-sectional study. The participants were basketball players who belonged to youth basketball developmental teams (female and male) from under-12 (U12) to under-17 (U17) categories. Ankle joint dorsiflexion range of motion was evaluated with the weight-bearing lunge test through the Leg Motion system. The distance achieved was recorded in centimeters. (3) Results: 693 basketball players who met the eligibility criteria and volunteered to participate were included in the study. The mean (SD) of ankle joint dorsiflexion was 10.68 (2.44) cm and the reference values were: excessive hypomobility < 6.09 (0.54) cm; hypomobility 6.09 (0.88) cm-8.43 (0.77) cm; normal 8.44 (0.77)-13.11 (0.79) cm; hypermobility 13.11 (0.74)-15.44 (0.86) cm; and excessive hypermobility >15.44 (0.86) cm. (4) Conclusions: This study provides ankle joint dorsiflexion reference values in youth basketball players from 12 to under 17 years old.

International Perspectives on Joint Hypermobility: A Synthesis of Current Science to Guide Clinical and Research Directions

ABSTRACT

There is exponential clinical and research interest in joint hypermobility due to recognition of the complexity of identification, assessment, and its appropriate referral pathways, ultimately impacting management. This state-of-the-science review provides an international, multidisciplinary perspective on the presentation, etiology, and assessment of joint hypermobility, as it presents in those with and without a systemic condition. We synthesize the literature, propose standardizing the use of terminology and outcome measures, and suggest potential management directions. The major topics covered are (i) historical perspectives; (ii) current definitions of hypermobility, laxity, and instability; (iii) inheritance and acquisition of hypermobility; (iv) traditional and novel assessments; (v) strengths and limitations of current assessment tools; (vi) age, sex, and racial considerations; (vii) phenotypic presentations; (viii) generalized hypermobility spectrum disorder and hypermobility Ehlers-Danlos syndrome; and (ix) clinical implications and research directions. A thorough understanding of these topics will equip the reader seeking to manage individuals presenting with joint hypermobility, while mindful of its etiology. Management of generalized joint hypermobility in the context of a complex, multisystem condition will differ from that of acquired hypermobility commonly seen in performing artists, specific athletic populations, posttrauma, and so on. In addition, people with symptomatic hypermobility present predominantly with musculoskeletal symptoms and sometimes systemic symptoms including fatigue, orthostatic intolerance, and gastrointestinal or genitourinary issues. Some also display skeletal deformities, tissue and skin fragility, and structural vascular or cardiac differences, and these warrant further medical follow-up. This comprehensive review on the full spectrum of joint hypermobility will assist clinicians, coaches/sports trainers, educators, and/or researchers in this area.

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.

The prevalence and impact of orthostatic intolerance in young women across the hypermobility spectrum

Orthostatic intolerance (OI) is frequently reported in young women with generalized hypermobility spectrum disorder (G-HSD) and hypermobile EDS (hEDS). However, it remains currently unclear whether OI is a comorbidity or fundamental part of the pathophysiology of G-HSD or hEDS. This study investigated the prevalence and impact of OI in young women across the hypermobility spectrum. Forty-five women (14-30 years, 15 controls, 15 G-HSD, and 15 hEDS) undertook a head-up tilt (HUT) and active stand test. Postural Orthostatic Tachycardia Syndrome (POTS) and Orthostatic Hypotension (OH) were assessed using age-related criteria. Autonomic dysfunction and quality-of-life questionnaires were also completed. The prevalence of POTS was higher in women with G-HSD than hEDS and control groups during HUT (43% vs. 7% and 7%, respectively, p < 0.05), but similar between groups during the active stand (47%, 27%, and 13% for G-HSD, hEDS, and control, respectively). No participants had OH. hEDS and G-HSD participants reported more severe orthostatic symptoms and poorer quality of life than controls. Although POTS was observed in hypermobile participants, there is no conclusive evidence that its prevalence differed between groups due to differences between the HUT and active stand assessments. Nevertheless, OI and broader autonomic dysfunction impacted on their quality of life.

Outcome measures for assessing change over time in studies of symptomatic children with hypermobility: a systematic review

Background

Generalised joint hypermobility (GJH) is highly prevalent among children and associated with symptoms in a fifth with the condition. This study aimed to synthesise outcome measures in interventional or prospective longitudinal studies of children with GJH and associated lower limb symptoms.

Methods

Electronic searches of Medline, CINAHL and Embase databases from inception to 16th March 2020 were performed for studies of children with GJH and symptoms between 5 and 18 years reporting repeated outcome measures collected at least 4 weeks apart. Methodological quality of eligible studies were described using the Downs and Black checklist.

Results

Six studies comprising of five interventional, and one prospective observational study (total of 388 children) met the inclusion criteria. Interventional study durations were between 2 and 3 months, with up to 10 months post-intervention follow-up, while the observational study spanned 3 years. Three main constructs of pain, function and quality of life were reported as primary outcome measures using 20 different instruments. All but one measure was validated in paediatric populations, but not specifically for children with GJH and symptoms. One study assessed fatigue, reporting disabling fatigue to be associated with higher pain intensity.

Conclusions

There were no agreed sets of outcome measures used for children with GJH and symptoms. The standardisation of assessment tools across paediatric clinical trials is needed. Four constructs of pain, function, quality of life and fatigue are recommended to be included with agreed upon, validated, objective tools.

Connecting brain and body: Transdiagnostic relevance of connective tissue variants to neuropsychiatric symptom expression

The mind is embodied; thoughts and feelings interact with states of physiological arousal and physical integrity of the body. In this context, there is mounting evidence for an association between psychiatric presentations and the expression variant connective tissue, commonly recognised as joint hypermobility. Joint hypermobility is common, frequently under-recognised, significantly impacts quality of life, and can exist in isolation or as the hallmark of hypermobility spectrum disorders (encompassing joint hypermobility syndrome and hypermobile Ehlers-Danlos syndrome). In this narrative review, we appraise the current evidence linking psychiatric disorders across the lifespan, beginning with the relatively well-established connection with anxiety, to hypermobility. We next consider emerging associations with affective illnesses, eating disorders, alongside less well researched links with personality disorders, substance misuse and psychosis. We then review related findings relevant to neurodevelopmental disorders and stress-sensitive medical conditions. With growing understanding of mind-body interactions, we discuss potential aetiopathogenetic contributions of dysautonomia, aberrant interoceptive processing, immune dysregulation and proprioceptive impairments in the context of psychosocial stressors and genetic predisposition. We examine clinical implications of these evolving findings, calling for increased awareness amongst healthcare professionals of the transdiagnostic nature of hypermobility and related disorders. A role for early screening and detection of hypermobility in those presenting with mental health and somatic symptoms is further highlighted, with a view to facilitate preventative approaches alongside longer-term holistic management strategies. Finally, suggestions are offered for directions of future scientific exploration which may be key to further delineating fundamental mind-body-brain interactions.

Impact of heritable disorders of connective tissue on daily life of children: Parent perspectives

AIM

The aim of this study was to investigate parent perspectives on how heritable disorders of connective tissue (HDCT) affect a child's everyday life. In addition, this study aimed to determine if parents seeking health professional services perceive their children with HDCT to have difficulties with activities reliant on hand function.

METHODS

This cross-sectional study used a questionnaire for parents to explore the impact of an HDCT on a child's ability to carry out everyday activities. Parents of children (8-18 years) attending a tertiary connective tissue dysplasia clinic, over a 12-month period, were invited to participate.

RESULTS

We analysed 100 surveys completed by parents. Children with Ehlers-Danlos syndrome-hypermobile type, joint hypermobility syndrome (48%) and osteogenesis imperfecta (42%) were the largest diagnostic groups represented. Pain (73%) and fatigue (68%) were the most common symptoms parents perceived to affect day-to-day activities. More parents were satisfied with their child's self-care (61%) than school participation (33%). Keeping up with handwriting (71%) and gross motor activities (70%) were the most frequently reported difficulties at school. Most parents (65%) reported leisure activity difficulties, with pain (64%) and fatigue (60%) as the main contributing factors.

CONCLUSIONS

This study has provided new knowledge about the concerns of parents with their child's engagement in everyday life including the impact of HDCT on hand function. Further research is needed on effective management strategies to reduce symptoms and improve hand function for these children.

Hypermobile Ehlers-Danlos syndromes: Complex phenotypes, challenging diagnoses, and poorly understood causes

The Ehlers-Danlos syndromes (EDS) are a group of heritable, connective tissue disorders characterized by joint hypermobility, skin hyperextensibility, and tissue fragility. There is phenotypic and genetic variation among the 13 subtypes. The initial genetic findings on EDS were related to alterations in fibrillar collagen, but the elucidation of the molecular basis of many of the subtypes revealed several genes not involved in collagen biosynthesis or structure. However, the genetic basis of the hypermobile type of EDS (hEDS) is still unknown. hEDS is the most common type of EDS and involves generalized joint hypermobility, musculoskeletal manifestations, and mild skin involvement along with the presence of several comorbid conditions. Variability in the spectrum and severity of symptoms and progression of patient phenotype likely depend on age, gender, lifestyle, and expression domains of the EDS genes during development and postnatal life. In this review, we summarize the current molecular, genetic, epidemiologic, and pathogenetic findings related to EDS with a focus on the hypermobile type.

Psychiatric Manifestations of Ehlers-Danlos Syndrome in Adolescents: A Case Report and Literature Review

Background:

Ehlers-Danlos Syndromes (EDS) comprise a group of heterogeneous hereditary connective tissue disorders [1, 2]. Psychiatric disorders such as depression, anxiety, panic disorder, agoraphobia, schizophrenia, neurodevelopmental disorders, personality disorder, eating disorders, substance misuse and interpersonal issues have been reported in the literature to be associated with EDS [1-3].

Objectives:

The case of a 15-year old male who was hospitalized after a suicide attempt by gunshot, who was discovered to have symptoms suggestive of EDS, is presented in this paper along with the results of a literature search of psychiatric manifestations of EDS in children and adolescents.

Methods:

Literature review was conducted on the UpToDate website on March 11, 2020 to review symptoms of Ehlers-Danlos Syndrome for the purpose of preliminary diagnosis of this patient. Additional literature search was conducted on PubMed on 4/2/20 at 12:10 P.M. and on 4/9/20 at 10:51 P.M. and on the search engine Google on 4/2/20 at 12:25 P.M. On May 11, 2020 at 2 P.M., another web search was conducted with a review of 6 different websites pertaining to Ehlers-Danlos Syndrome.

Results:

A systematic review of psychiatric manifestations of Ehlers-Danlos Syndromes revealed a strong incidence of psychiatric symptoms.

Conclusion:

Our patient’s psychiatric symptoms of depression, suicidal ideations, anxiety and social and educational struggles may have been at least partially due to chronic pain- abdominal, headache and musculoskeletal, and social ostracization associated with Ehlers-Danlos Syndrome. Education regarding this illness helped our patient’s recovery as he came to understand why he was so “odd” and the cause of his multisystemic chronic pain.

Psychosocial and Motor Characteristics of Patients With Hypermobility

OBJECTIVES

To identify psychosocial and motor aspects related to joint hypermobility (JH) in a sample from almost all Brazilian states by age range and sex; to characterize JH by the Beighton total score ≥4, ≥5, and ≥6 according to sex and age and atypicality in the sitting position and in the hands; identify, in the total sample, manifestations of "growing pain" and its location, fatigue, attention deficit, anxiety, insomnia, drowsiness, apathy, depression, delay in walking, not crawling or crawling differently, school performance, spatial orientation and/or temporally impaired, social isolation, and being stigmatized as "lazy/clumsy/apathetic".

METHODS

This retrospective, observational, quantitative, and cross-sectional study used data obtained through analyses of descriptive and inferential crossings between 2012 and 2020 of 482 medical records of individuals between 1 and 76 years of age, from most Brazilian states. All patients previously diagnosed with "joint hypermobility syndrome" (JHS) and "Ehlers-Danlos syndrome hypermobility type" (EDS-HT) had their medical records reassessed, following the guidelines established in 2017. The analysis of GJH was performed using the updated method by Beighton method; atypical characteristics were investigated in the hands and the ability to sit in the "W" and the "concave" positions. The characteristics and manifestations of "growing pain" and its location were analyzed in the total sample, fatigue, insomnia, drowsiness, apathy, depression, social isolation, attention deficit, anxiety, stigmatization as "lazy," clumsy/restless, impaired school performance, and spatial and/or temporal orientation. Descriptive and inferential statistical methods were used, such as Mean, Median, Mode, Standard Deviation, Standard Error, Maximum Value, Minimum Value, Komolgorov-Smirnov, Significance, Relative Value, Absolute Value, Mann-Whitney U, and Correlation of Spearman.

RESULTS

JH in the total sample predominated in the upper limbs, the majority were women, represented by 352 (73.02%), 15 years old or older with 322 (66.80%), 312 (64.73%) had a Beighton total score ≥6, which decreased as the age increased. Always sitting in the "concave" position was represented by 54.15% and the ability to sit in the "W" position by 39.21%; signs on the hands totaled between 27.59 and 44.19% with a significant correlation between the variables. Among the characteristics, fatigue predominated, followed by an awkward/clumsy/restless individual, attention deficit, anxiety and stigmatized as "lazy," insomnia, drowsiness, apathy, depression, impaired spatial and/or temporal orientation, and social isolation. From the total sample, pain in the lower limbs was reported by 55.81% and having or having had "growing pain" was reported by 36.93%, delay in walking occurred in 19.92%, 15.35% did not crawl or crawled differently, and for 12.86%, school performance was impaired. Higher Beighton total scores showed a trend towards motor implications and correlation between variables. Ability to still sit in the "concave" position was possible for 54.15% and to sit in the "W" position for 39.21%.

CONCLUSION

In the total sample, the JH characteristic prevails in the upper limbs of female children, adolescents and adults, with a total Beighton score ≥6. Most sit in the "concave" position and less than half also sit in the "W" position and with atypical hand postures. The higher Beighton scores, which include the upper limbs, show a tendency to not crawl or crawl differently, delayed ambulation, and impaired school performance. The predominance of JH in the upper limbs is suggestive of a justification for not crawling or crawling differently. Characteristics of atypical motor performance in hands and sitting posture, in addition to fatigue, pain since childhood, anxiety, apathy, depression, sleep disorders, stigmatization, attention deficit, spatial and/or temporal orientation impairment, and social isolation are characteristics. suggestive of psychosocial implications at different ages. Future studies with motor and psychosocial aspects of people with JH will help to identify the phenotype of this population and consequent guidance for clinical management based on the motor and psychosocial aspects of people with JH.

Prevalence of ADHD and Autism Spectrum Disorder in Children with Hypermobility Spectrum Disorders or Hypermobile Ehlers-Danlos Syndrome: A Retrospective Study

INTRODUCTION

Hypermobility spectrum disorders (HSD) and hypermobile Ehlers-Danlos syndrome (hEDS) are both characterized by generalized hypermobility, in combination with pain, affected proprioception, and pronounced fatigue. Clinical observation indicates that behavioral problems, hyperactivity, and autistic traits are overrepresented in children with those conditions. The purpose of this retrospective study was to establish the prevalence of attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) among children with HSD and hEDS treated in our clinic since 2012.

SUBJECTS AND METHODS

Since Ehlers-Danlos syndrome (EDS) diagnostic criteria and international classification were changed in 2017, we equate the older diagnosis EDS hypermobility type with the newer hEDS and the older hypermobility syndrome with HSD. A registry search from the computerized medical record system found 201 children (88 boys, 113 girls) aged 6-18 years who were treated at our pediatrics department with the diagnoses HSD or EDS. All medical records (113 with HSD, 88 with EDS) were reviewed, and key symptoms such as fatigue and pain, as well as diagnosis of ADHD/ASD, were recorded.

RESULTS

All EDS cases could be classified as hEDS. Of the entire study cohort, 16% had a verified ADHD diagnosis and a further 7% were undergoing ADHD diagnostic investigation. Significantly more children with hEDS had ADHD compared to children with HSD (p=0.02). In the age group 15-16 years, 35% of those with hEDS had ADHD and, among those aged 17-18 years, ADHD was present in 46%. Children with coexisting ADHD showed a significantly higher proportion of associated symptoms such as fatigue, sleep-problems, and urinary tract problems. ASD had been verified in 6% of the children. Of those with ASD, 92% had sleep problems.

CONCLUSION

This study shows a strong association between HSD or hEDS and ADHD or ASD. Therefore, children with HSD or hEDS may need to be routinely screened for neuropsychiatric symptoms.

Symptom complaints and impact on functioning in youth with hypermobile Ehlers-Danlos syndrome

Hypermobile Ehlers-Danlos syndrome (hEDS), a genetic connective tissue disorder, involves several body systems which makes symptom management and functioning difficult. The aim of this study was to understand pediatric hEDS patients' symptoms and primary complaints. Additionally, we examined the cumulative impact of symptoms on physical and psychological functioning. Thirty-four youth with hEDS were recruited from a genetics clinic and reported the hardest thing about having hEDS, their pain, fatigue, physical symptoms, functional disability, anxiety, and depression. Physical symptoms (pain and fatigue) and limitations (keeping up with friends) were reported as the most difficult parts of having hEDS. A higher number of somatic symptoms was the strongest predictor of disability, anxiety, and depression. Physical symptoms are subjectively distressing and significantly related to impairments in physical and psychological functioning. Thus, addressing these varied symptoms in treatment may yield better functioning in youth with hEDS.

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.

Risk of Injury in Physically Active Students: Associated Factors and Quality of Life Aspects

Background: The aim of this study was to assess the potential factors of hypermobility and pain threshold on the risk of injury in physically active students and to verify which domains of quality of life are rated lower by young people with a history of injuries. Methods: The study included 278 students (138 women and 140 men) who regularly undertake physical activity. Anthropometric measurements, body composition, pain threshold, incidence of hypermobility syndrome, information on the history of injuries to the locomotor system, and the quality of life of the study participants were collected. Results: In the group studied, hypermobility and pain threshold had a statistically significant related on the risk of injury. Participants with a history of injuries had lower scores for an individual’s overall perception of their own health and the physical domain. There were also significant differences in the psychological domain of the quality of life between males and females with a history of injuries. Conclusion: In the studied group, the risk of injuries was related to diagnosed hypermobility and pain threshold measured on the lower limbs. The study also showed that people with a history of injuries had statistically significantly lower scores in the individual general perception of their own health and in the physical domain. Gender had a significant impact on the quality of life of people with injuries.

Joint Hypermobility Classes in 9-Year-Old Children from the General Population and Anxiety Symptoms

OBJECTIVE

To obtain joint hypermobility classes in children from the general population and to study their characteristics in relation to anxiety measures.

METHODS

A total of 336 nine-year-old children from the general population were clinically assessed through 9 items of hypermobility, and their parents reported about the severity of anxiety symptoms. Latent class analysis was estimated to group the children according to the presence of hypermobility symptoms, and the obtained classes were related to anxiety.

RESULTS

A 2-class solution, labeled as high hypermobility and low hypermobility, best fitted the data. Children in the high hypermobility group scored higher in separation anxiety, social phobia, physical injury fears, and total anxiety than did those in the low group. When applying the threshold reference scores to the total anxiety score, 7.4% of children in the high hypermobility group versus 6% in the low group were reported to experience clinical elevations on total anxiety.

CONCLUSION

High symptoms of hypermobility are associated with higher scores in anxiety symptoms in children from the general population. Children with frequent symptoms of hypermobility may benefit from screening for anxiety symptoms because a subset of them are experiencing clinical elevations and may need comprehensive physical and psychological treatment.

Recognizing and Effectively Managing Hypermobility-Related Conditions

Hypermobility spectrum disorder (HSD) and hypermobile Ehlers-Danlos syndrome (hEDS) can cause widespread or chronic pain, fatigue, and proprioceptive and coordination deficits resulting in functional restrictions. These conditions are common and often unrecognized, and patients are likely to present in physical therapy for musculoskeletal injuries, pain, or coordination deficits. Although physical therapy is considered central to managing these conditions, many patients report pain and iatrogenic injuries due to inappropriate interventions. The diagnostic classification for these conditions was revised in 2017 to supersede previous diagnostic categories of Joint Hypermobility Syndrome and Ehlers-Danlos Syndrome-hypermobility type/type III. It is now known that these conditions affect multiple body systems and not just joints and that patients require a holistic approach. This Perspective article will describe the 2017 diagnostic classification system, clinical presentation, examination, evaluation, and management of patients with HSD/hEDS. Both adult and pediatric cases are presented to illustrate the patient management concepts discussed. This knowledge can lead to more effective management of this patient population.

Hypermobility, developmental coordination disorder and physical activity in an Irish paediatric population

OBJECTIVE

The primary aim of the study was to explore the prevalence of generalized joint hypermobility (GJH) and generalized hypermobility spectrum disorder (gHSD) using the new classification system in a community paediatric physiotherapy service in Ireland. The second aim was to explore the relationship between GJH, gHSD and physical activity level, while considering the association of probable developmental coordination disorder (pDCD).

METHODS

A case-controlled cross-sectional study of children aged 6-12 years, recruited from the community paediatric physiotherapy department (n = 32) and a local school (n = 41), was carried out. A Beighton score of ≥6/9 distinguished GJH. The new framework for hypermobility spectrum disorder (HSD) was used. Self-reported physical activity level was measured using the Physical Activity Questionnaire-Older Children. A parent-reported validated questionnaire screened for pDCD.

RESULTS

The prevalence of GJH was 21.9% of children attending physiotherapy. One child in the physiotherapy group was identified as having gHSD, with a prevalence of 3.1%. There was no significant difference in physical activity level between children with and without GJH attending physiotherapy (independent samples t-test, p = 0.28). Probable developmental coordination disorder (pDCD) was observed in 71.9% of children attending physiotherapy. There was no significant difference in the number of children with pDCD in those with and without GJH (Fisher's exact test, p = 0.370).

CONCLUSIONS

This study was the first to explore the prevalence of GJH and gHSD in the paediatric physiotherapy population in Ireland. The presence of GJH did not affect self-reported physical activity level or motor coordination in children attending physiotherapy.

Characterizing adolescents with heavy menstrual bleeding and generalized joint hypermobility

Patients with generalized joint hypermobility (JHM) may experience excessive bruising/bleeding, with heavy menstrual bleeding (HMB) commonly reported. We performed a retrospective review of 30 adolescents seen in a Young Women's Hematology Clinic with both HMB and JHM. We found that (1) a significant delay (mean 36 months, range 5-72) occurred between menarche and referral to specialty care, (2) HMB had moderate to severe impact on school and physical activities in 60% of patients, and (3) most patients (68%) required escalation of their initial therapy. We suggest providers consider JHM as a risk factor for a more complex clinical course.

Hypermobility of joints in dancers

OBJECTIVES

The current understanding of hypermobility and its diagnostic criteria is still insufficient to create a complete and systematic clinical presentation of the disorder. The objective of this study was to assess the prevalence of joint hypermobility syndrome (JHS) amongst a cohort of jazz dancers, by analyzing its presence in accordance with a number of diagnostic criteria, and to verify potential risk factors for joint hypermobility in jazz dancers.

METHODS

77 jazz dancers from the Polish Dance Theater were examined (58 female and 19 male). The prevalence of JHS was assessed using the following diagnostic tools: a structured interview, Beighton score, Grahame & Hakim questionnaire, and Sachse's criteria, in the modified version proposed by Kapandji.

RESULTS

The prevalence of JHS in this cohort of jazz dancers differed significantly, depending on which criteria were adopted (p = 0.001) with Beighton score, Grahame & Hakim questionnaire, and Sachse's criteria identifying 64.9%, 74% and 59.7% of the sample as JHS respectively. Hypermobility was significantly more prevalent in women than men (p < 0.05).

CONCLUSIONS

This study demonstrated a significant prevalence of joint hypermobility in jazz dancers and corroborates the findings of other researchers, indicating the need for unified diagnostic criteria for JHS in dancers.

Factors affecting quality of life in children and adolescents with hypermobile Ehlers-Danlos syndrome/hypermobility spectrum disorders

Hypermobile Ehlers-Danlos syndrome (hEDS) is a hereditary disorder of connective tissue, often presenting with complex symptoms can include chronic pain, fatigue, and dysautonomia. Factors influencing functional disability in the pediatric hEDS population are incompletely studied. This study's aims were to assess factors that affect quality of life in children and adolescents with hEDS. Individuals with hEDS between the ages 12-20 years and matched parents were recruited through retrospective chart review at two genetics clinics. Participants completed a questionnaire that included the Pediatric Quality of Life Inventory (PedsQL™), PedsQL Multidimentional Fatigue Scale, Functional Disability Inventory, Pain-Frequency-Severity-Duration Scale, the Brief Illness Perception Questionnaire, measures of anxiety and depression, and helpful interventions. Survey responses were completed for 47 children and adolescents with hEDS/hypermobility spectrum disorder (81% female, mean age 16 years), some by the affected individual, some by their parent, and some by both. Clinical data derived from chart review were compared statistically to survey responses. All outcomes correlated moderately to strongly with each other. Using multiple regression, general fatigue and pain scores were the best predictors of the PedsQL total score. Additionally, presence of any psychiatric diagnosis was correlated with a lower PedsQL score. Current management guidelines recommend early intervention to prevent disability from deconditioning; these results may help identify target interventions in this vulnerable population.

Effect of generalized ligamentous hyperlaxity related of quality of life in the foot: a case controlled study

Generalized ligamentous hyperlaxity (GLH) has been shown to predispose an individual to a number of orthopaedic conditions. Little is known about how GLH affects people' foot health-related quality of life. This study analyses a sample of people with GLH and people without GLH with normalised reference values of the scores collected with regard to using the Foot Health Status Questionnaire (FSHQ). A total of 100 respondents with mean age of 22.69 ± 3.78 years old, who attended a health centre were classified as GLH (n = 50) or non-GLH (n = 50). The GLH was determined of the patients with and without GLH using assessment with Beighton tool and the scores on the FHSQ were compared. The control group recorded higher scores in the First Section for foot pain, foot function and general foot health, and lower scores in footwear. In the Second Section, they obtained higher scores in social capacity and lower scores in physical activity, vigour and general health. Differences between the two groups were evaluated through a t-test for independent samples, showing statistical significance (P<0.001). This study has detected measurable differences of association between GLH (Beighton score ≥4) with impaired quality of life related to foot health.

Italian validation of the functional difficulties questionnaire (FDQ-9) and its correlation with major determinants of quality of life in adults with hypermobile Ehlers-Danlos syndrome/hypermobility spectrum disorder

The 2017 nosology defines the new criteria for hypermobile Ehlers-Danlos syndrome (hEDS), which is now considered one end of a continuous spectrum encompassing isolated, nonsyndromic joint hypermobility (JH) and hypermobility spectrum disorders (HSDs). Preliminary data indicate a link between JH and neurodevelopmental disorders and, in particular, developmental coordination disorder (DCD) in children. Assessing DCD in adults is difficult and the recently described functional difficulties questionnaire 9 (FDQ-9) is one of the few available tools. The aims of this study are to (a) validate FDQ-9 written in Italian and present normal values in 230 Italian controls; (b) explore the relationship of FDQ-9 with the brief pain inventory, composite autonomic symptom score 31, multidimensional fatigue inventory, attention deficit/hyperactivity disorder self-report version 1.1, and the SF-36 for quality of life in 105 Italian adults with hEDS/HSD. Validation of the FDQ-9 in Italian was carried out by translation, cross-cultural adaptation and test/retest reliability analysis. A case-control study was performed comparing the FDQ-9 outcome between 105 patients and 105 sex- and age-matched controls. Fifty-nine percent of the patients resulted positive compared to the 3.8% of controls (p value < .00001). In patients, FDQ-9 positive result associated with positive attention deficit/hyperactivity disorder self-report version 1.1 (OR = 4.04). Multivariate regression analysis comparing FDQ-9 with the other questionnaires demonstrated a strong association between positive FDQ-9 and the number of painful joints. Our preliminary data open wider management and therapeutic perspectives for coordination difficulties in hypermobile individuals.

Physical and mechanical therapies for lower limb symptoms in children with Hypermobility Spectrum Disorder and Hypermobile Ehlers-Danlos Syndrome: a systematic review

Background

Hypermobility Spectrum Disorder and Hypermobile Ehlers Danlos Syndrome are two common heritable genetic disorders of connective tissue. Both conditions are characterised by excessive joint range of motion and the presence of musculoskeletal symptoms, and are associated with joint instability, motion incoordination, decreased joint position sense, and musculoskeletal pain. Hypermobility Spectrum Disorder is the new classification for what was previously known as Joint Hypermobility Syndrome. This systematic review evaluates the evidence for physical and mechanical treatments for lower limb problems in children with Hypermobility Spectrum Disorder and Hypermobile Ehlers Danlos Syndrome.

Methods

MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, PUBMED and CINAHL were searched to October 2017 for randomised controlled trials (RCT) and quasi-RCTs evaluating physical and mechanical interventions for lower limb problems in children with hypermobility. Two authors independently screened studies for eligibility for inclusion and three review authors independently assessed risk of bias of included studies. One author extracted and analysed statistical data, which were checked by a second author.

Results

Two RCTs including a total of 86 participants were eligible for inclusion. Trials evaluated differences between generalised versus targeted physiotherapy programs and between performing knee extension exercises to the neutral versus hypermobile range. There was no clear benefit of any of the physical therapies evaluated.

Conclusion

There is very limited evidence to guide the use of physical and mechanical therapies for lower limb problems in children with Hypermobility Spectrum Disorder and Hypermobile Ehlers Danlos Syndrome. Mechanical therapies have not been evaluated in RCTs and results of the two RCTs of physical therapies do not definitively guide physical therapy prescriptions. Current studies are limited by small sample sizes and high attrition rates. No physical therapy has been compared to a sham intervention no intervention or no intervention, so overall effectiveness is unknown.

Pain and sleep quality in children with non-vascular Ehlers-Danlos syndromes

The objective of this study was to explore the factors contributing to quality of life in pediatric patients with non-vascular Ehlers-Danlos syndromes (EDS). Data were analyzed on 41 children with a diagnosis of non-vascular EDS from the de-identified data available from the National Institute on Aging (NIA) study of heritable disorders of connective tissue. Children under age 19 years were seen as part of a long-term evaluation project from 2003 to 2013 on a larger natural history of patients with heritable disorders of connective tissue. Data collected included medical history, physical examination findings, diagnostic study results, and responses on validated questionnaires. We reviewed a sub-cohort of children with a diagnosis of non-vascular EDS and explored pain severity and interference via the Brief Pain Inventory, and sleep quality via the Pittsburgh Sleep Quality Index. Pain severity had a strong correlation with pain interference, and both were similar to other disorders that include chronic pain reported in the literature. Sleep quality did not correlate with pain severity or interference, but all patients had poor sleep quality in comparison to historical controls. We conclude that pain and sleep are significant issues in the pediatric non-vascular EDS population, and future research may be directed toward these issues.

Pediatric Pain Syndromes and Noninflammatory Musculoskeletal Pain

Chronic musculoskeletal pain (CMP) is one of the main reasons for referral to a pediatric rheumatologist and is the third most common cause of chronic pain in children and adolescents. Causes of CMP include amplified musculoskeletal pain, benign limb pain of childhood, hypermobility, overuse syndromes, and back pain. CMP can negatively affect physical, social, academic, and psychological function so it is essential that clinicians know how to diagnose and treat these conditions. This article provides an overview of the epidemiology and impact of CMP, the steps in a comprehensive pain assessment, and the management of the most common CMPs.

Survey on joint hypermobility in university students aged 18-25 years old

BACKGROUND

Joint hypermobility is defined as a wide range of movements beyond the physiological limits, it has been recognized in healthy people, gymnasts, acrobats, and carriers of genetic affections of connective tissue. A survey among young adults was conducted to describe the frequency of joint hypermobility, estimating its impact on function and quality of life.

METHODS

Volunteer university students aged 18 to 25 years old who answered a valid 5-item questionnaire about hypermobility, a physical activity questionnaire, and the Brazilian version of the Medical Outcome Survey Short Form 36 (SF-36) were included. Hypermobility was also assessed by a guided self-examination, with Beighton's criteria being scored and scores greater than or equal to 4 or less than 4 being discriminated.

RESULTS

A total of 388 subjects were included, of which 299 were women (77.06%) and 89 were men (22.94%); the median age was 23 years old. Generalized joint hypermobility (Beighton score ≥ 4) was observed in 104 individuals (26.8%). Localized hypermobility (Beighton score 1-3) was observed in 135 (34.79%) individuals, where the hypermobility of the 5th finger was the most frequent in 165 (57.47%) individuals, followed by hypermobility of the thumb in 126 (32.56%) individuals, hypermobility of the elbows and knees each in 72 (18.6%) individuals, and hypermobility of the spine in 69 (17.79%) individuals. The descriptive observation of physical activity indicated regular practice. The correlation coefficients between the SF-36 domains and hypermobility scores were very low and statistical comparison not significant.

CONCLUSION

In this population of youngsters, predominantly women, localized hypermobility was more frequent than generalized hypermobility; however, with low impact on health domains and quality of life scores, estimated in each domain of the SF-36, the physical and mental component scores, and the time dedicated to physical activity.

Contralateral knee hyperextension is associated with increased anterior tibial translation and fewer meniscal injuries in the anterior cruciate ligament-injured knee

PURPOSE

To investigate the influence of hyperextension of the contralateral healthy knee on anterior tibial translation (ATT) and the presence of associated injuries in the anterior cruciate ligament (ACL)-injured knee.

METHODS

A local patient data register containing the surgical and clinical data of patients undergoing ACL reconstruction was analyzed. Patients were divided into groups according to the degree of hyperextension of the contralateral knee: normal (Group A ≤ 0°), mild (Group B 1°-5°), moderate (Group C 6°-10°), and severe (Group D > 10°). The ATT was measured in both knees preoperatively and 6 months postoperatively using the KT-1000 arthrometer. The presence of associated meniscal and cartilage injuries was noted. Using multivariate analysis, Groups B, C, and D were compared with Group A, using this group as a reference.

RESULTS

A total of 10,957 patients were available in the register and 8502 (Group A n = 4335, Group B n = 3331, Group C n = 771, Group D n = 65) were included in the final analysis. Groups B (10.3 mm; 95% CI 0.06-0.042, p < 0.0001) and C (10.6 mm; 95% CI 0.23-0.89, p = 0.006) showed significantly greater preoperative ATT in the injured knee compared with the control group (10.1 mm). Moreover, at the 6-month follow-up, greater ATT was observed for Groups B (8.5 mm; 95% CI 0.13-0.45, p < 0.0001), C (8.5 mm; 95% CI 0.02-0.60, p = 0.035), and D (9.1 mm; 95% CI - 0.08-1.77, p = 0.082) compared with Group A (8.2 mm). Meniscal injuries were less frequent in patients with contralateral hyperextension [Group B 903 (27.1%) p < 0.0001, Group C 208 (27.0%) p = 0.0003, and Group D 12 (18.5%), 0.012] compared with the control group [Group A 1479 (34.1%)].

CONCLUSION

Contralateral knee hyperextension is associated with greater pre- and postoperative ATT in the ACL-injured knee. In patients with contralateral knee hyperextension, concomitant injuries to the menisci are less frequent. Surgeons should consider grafts with superior properties regarding postoperative anteroposterior laxity to patients with contralateral knee hyperextension.

The natural history of children with joint hypermobility syndrome and Ehlers-Danlos hypermobility type: a longitudinal cohort study

Objectives

The objective of the manuscript was to describe the natural history of complaints and disability in children diagnosed with joint hypermobility syndrome (JHS)/Ehlers-Danlos-hypermobility type (EDS-HT) and to identify the constructs that underlie functional decline.

Methods

One hundred and one JHS/EDS-HT children were observed over 3 years and assessed at three time points on the following: functional impairments, quality of life, connective tissue laxity, muscle function, postural control and musculoskeletal and multi-systemic complaints. Cluster analysis was performed to identify subgroups in severity. Clinical profiles were determined for these subgroups, and differences were assessed by multivariate analysis of covariance. Mixed linear regression models were used to determine the subsequent trajectories. Finally, an exploratory factor analysis was used to uncover the underlying constructs of functional impairment.

Results

Three clusters of children were identified in terms of functional impairment: mild, moderately and severely affected. Functional impairment at baseline was predictive of worsening trajectories in terms of reduced walking distance and decreased quality of life (P ⩽ 0.05) over 3 years. Multiple interactions between the secondary outcomes were observed, with four underlying constructs identified. All four constructs (multi-systemic effects, pain, fatigue and loss of postural control) contributed significantly to disability (P ⩽ 0.046).

Conclusion

Children diagnosed with JHS/EDS-HT who have a high incidence of multi-systemic complaints (particularly, orthostatic intolerance, urinary incontinence and diarrhoea) and poor postural control in addition to high levels of pain and fatigue at baseline are most likely to have a deteriorating trajectory of functional impairment and, accordingly, warrant clinical prioritization.

The evidence-based rationale for physical therapy treatment of children, adolescents, and adults diagnosed with joint hypermobility syndrome/hypermobile Ehlers Danlos syndrome

New insights into the phenotype of Joint Hypermobility Syndrome (JHS) and Ehlers-Danlos Syndrome-hypermobile type (hEDS) have raised many issues in relation to classification, diagnosis, assessment, and treatment. Within the multidisciplinary team, physical therapy plays a central role in management of individuals with hypermobility related disorders. However, many physical therapists are not familiar with the diagnostic criteria, prevalence, common clinical presentation, and management. This guideline aims to provide practitioners with the state of the art regarding the assessment and management of children, adolescents, and adults with JHS/hEDS. Due to the complexity of the symptoms in the profile of JHS/hEDS, the International Classification of Functioning, Disability and Health (ICF) is adopted as a central framework whereby the umbrella term of disability is used to encompass functions, activities and participation, as well as environmental and personal factors. The current evidence-based literature regarding the management of JHS/hEDS is limited in size and quality and there is insufficient research exploring the clinical outcomes of a number of interventions. Multicenter randomized controlled trials are warranted to assess the clinical and cost-effectiveness of interventions for children and adults. Until further multicenter trials are conducted, clinical decision-making should be based on theoretical and the current limited research evidence. For all individuals diagnosed with JHS/hEDS, international consensus and combined efforts to identify risk profiles would create a better understanding of the pathological mechanisms and the potential for optimizing health care for affected individuals. © 2017 Wiley Periodicals, Inc.

Physical and Psychosocial Characteristics of Current Child Dancers and Nondancers With Systemic Joint Hypermobility: A Descriptive Analysis

Study Design Cross-sectional study. Background The effect of current participation in dance training on joint pain and instability, fatigue, and quality of life is unknown. Objectives To examine differences in joint pain, instability, gross motor skills, nonmusculoskeletal systemic manifestations, health-related quality of life (HRQoL), and fatigue between children with joint hypermobility syndrome/Ehlers-Danlos syndrome-hypermobility type (JHS/EDS-HT) who currently undertake formal dance training and those who do not. Methods Children with JHS/EDS-HT and 1 parent completed reports providing data on demographic variables, symptoms, organized activity participation, HRQoL, and fatigue. Physical and functional measures included extent of hypermobility, aerobic fitness, balance, and muscle endurance. Results Of the 102 participating children, 22 currently undertook dance classes, averaging 3.3 h/wk. While the dancers reported a number of painful joints similar to that reported by nondancers (mean ± SD, 5.5 ± 3.7 versus 6.4 ± 3.9 joints, respectively; P = .36), they reported significantly lower pain levels on a 0-to-10 scale (3.8 ± 3.3 versus 5.6 ± 3.4, P = .04) and found pain to be less problematic, affecting less of their body. They reported fewer unstable joints (1.0 ± 1.0 versus 2.0 ± 1.8 joints, P = .001), despite being more hypermobile (Beighton score, 7.3 ± 1.4 versus 6.6 ± 1.6 on a 9-point scale, P = .047; Lower Limb Assessment Score, 9.2 ± 2.0 versus 8.1 ± 1.9 on a 12-point scale, P = .02). The dancers had significantly better HRQoL in the subdomain of school functioning (P = .004) and reported less fatigue (P = .024). Conclusion Children with JHS/EDS-HT who are currently undertaking formal dance training have fewer joint pain and instability symptoms, less fatigue, and better HRQoL; however, the cross-sectional nature of the study means that causation cannot be determined.

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.

A connective tissue disorder may underlie ESSENCE problems in childhood

BACKGROUND

Ehlers-Danlos syndrome hypermobility type, also known as Joint Hypermobility Syndrome (EDS-HT/JHS), is the most common hereditary disorder of the connective tissue (HDCT). It is characterized by tissue fragility, joint hypermobility and a wide range of articular and non-articular manifestations, which often appear in infancy. The clinical picture of EDS-HT/JHS is poorly known by the medical community, as is the presence of "ESSENCE" (Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations) problems in affected children.

AIM

The present work reviews the clinical and empirical evidence for ESSENCE difficulties in children with EDS-HT/JHS.

METHOD

A narrative review of the literature was undertaken following a comprehensive search of scientific online databases and reference lists. This included publications of quantitative and qualitative research.

RESULTS

Motor abnormality, hyperactivity/hypoactivity, inattention, speech/language, social interaction, behavioral, sleep, feeding and emotional problems are ESSENCE difficulties for which there is some evidence of an association with EDS-HT/JHS.

CONCLUSION

Children with EDS-HT/JHS present ESSENCE problems that often coexist and tend to be recognized before the HDCT. Clinicians encountering children with ESSENCE problems should consider the possibility of an underlying HDCT such as EDS-HT/JHS, probably influencing neurodevelopmental attributes in a subgroup of children. Awareness of these interconnected clinical problems might help improve early referral, diagnosis and treatment of EDS-HT/JHS.

When flexibility is not necessarily a virtue: a review of hypermobility syndromes and chronic or recurrent musculoskeletal pain in children

Chronic or recurrent musculoskeletal pain is a common complaint in children. Among the most common causes for this problem are different conditions associated with hypermobility. Pediatricians and allied professionals should be well aware of the characteristics of the different syndromes associated with hypermobility and facilitate early recognition and appropriate management. In this review we provide information on Benign Joint Hypermobility Syndrome, Ehlers-Danlos Syndrome, Marfan Syndrome, Loeys-Dietz syndrome and Stickler syndrome, and discuss their characteristics and clinical management.
