Abstract
Dyslexia and pain have recently been shown to correlate on a genetic level, but there has been little exploration of this association on the phenotypic level despite reports of increased pain in Attention Deficit Hyperactivity Disorder, which commonly co-occurs with dyslexia. In this study we test for an association between reading ability, which is the primary feature of dyslexia, and pain both in childhood and adulthood. Logistic regression modeling was used to test associations between reading ability in childhood and pain from childhood to midlife in a large UK birth cohort; the 1958 National Child Development Study. Associations were found between poor childhood reading ability and increased headache and abdominal pain in childhood, and between poor childhood reading ability and headache, eye pain, back pain, and rheumatism in adulthood. Mediation analyses indicated that socioeconomic status (defined by employment) fully mediated the association between poor reading ability in childhood and back pain at age 42. By contrast, the association between reading ability and eye pain acted independently of socioeconomic status. Different mechanisms were thus indicated for the association of reading with different pain types, including manual labor and a potential shared biological pathway. PERSPECTIVE: This study found a relationship between poor reading ability in childhood and pain in childhood and adulthood. Those with reading difficulties should be monitored for pain symptoms. Future research may uncover shared biological mechanisms, increasing our understanding of pain and potential treatments.

Pediatric joint hypermobility: a diagnostic framework and narrative review. Orphanet J Rare Dis 2023; 18:104. [PMID: 37143135 PMCID: PMC10157984 DOI: 10.1186/s13023-023-02717-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Accepted: 04/30/2023] [Indexed: 05/06/2023] Open
Abstract
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.

Abstract
Children with developmental coordination disorder (DCD) and joint hypermobility could present an overlap of symptoms and motor functional difficulties. The link between these two clinical conditions has not yet been clarified. Recent studies reported a high incidence (30–50%) of motor delay in children who are referred to hypermobility and of enhanced joint hypermobility in children with DCD. The aim of this study was to provide a critical review of the literature outlining the association between DCD or limited motor performance and joint hypermobility. Studies were eligible for inclusion if they were written in English and human-based. All the studies were first selected, looking for the presence of a clinical association between developmental coordination disorder or motor performance and hyperlaxity and reporting details of outcome. After a review of the full texts, 16 articles for a total of 1898 children met the inclusion criteria. In general, there was evidence of a higher incidence of motor delay or DCD in children who are referred to hypermobility and of enhanced joint hypermobility in children with DCD with similar range of functional difficulties. These results could influence the way to support children with rehabilitation and the type of intervention according to the prevalence of one of the two conditions.

Abstract
INTRODUCTION Hypermobile joints display a range of movement that is considered excessive, taking into consideration the age, gender and ethnic background of the individual. Joint hypermobility may present in a single joint, a few joints or in multiple joints and may be congenital or acquired with training, disease or injury. Hypermobile joints may be asymptomatic or may be associated with pain, fatigue, multisystemic complaints and significant disability. Furthermore, joint hypermobility may be a sign of an underlying hereditary disorder of connective tissue. PURPOSE This masterclass aims to provides a state-of-the-art review of the aetiology, epidemiology, clinical presentation, assessment and management of joint hypermobility and hypermobility related disorders using an evidence based and biopsychosocial approach. The new framework for classifying the spectrum of joint hypermobility disorders along with new diagnostic criteria for the hypermobile Ehlers Danlos syndrome, published by an international consortium of clinical experts and researchers in 2017 is integrated into the paper. IMPLICATIONS FOR PRACTICE People with joint hypermobility related disorders present to healthcare professionals with a wide range of symptoms which extend beyond the musculoskeletal system. Early recognition and treatment are key to effective management. A biopsychosocial and patient empowerment approach to functional restoration is recommended.

Abstract
OBJECTIVE The aim of this study was to evaluate the dental status and temporomandibular diseases (TMDs)-related symptoms in children with generalized joint hypermobility (GJH) and compare them with healthy controls (HCs). METHODS This is a cross-sectional, observational study carried out between September 2016 and April 2017. A total of 124 children with GJH (n = 62) and HC (n = 62) were enrolled. The GJH was assessed with the Beighton hypermobility score. The subjects were screened for dental status and TMD-related symptoms. The assessment included the index for "decayed," "missing," and "filled teeth" (DMFT, dmft); plaque; gingival bleeding; tooth mobility; and temporomandibular joint (TMJ) evaluation. RESULTS The mean Beighton hypermobility score was 6.3 ± 1.2 in the GJH group. Visible plaque index and gingival bleeding index scores were found to be significantly higher in children with GJH then in the HC (p = 0.031, p = 0.023). No differences were found regarding the DMFT scores between the groups (p = 0.16). Temporomandibular disorder-related symptom frequencies were significantly higher in children with GJH (p < 0.001). The most common clinically determined sign of TMD was clicking with a maximum active mouth-opening. Combined TMJ symptoms and TMD were observed in approximately one third of the children with GJH. CONCLUSIONS The presence of GJH in a child may be indicative of future dental or TMJ problems, and it may cause dental problems due to increased gingival bleeding index and visible plaque index scores. Therefore, children with GJH require preventive dental and TMJ care.

PART C, SEMINARS IN MEDICAL GENETICS 2021; 187:491-499.

Abstract
Joint hypermobility (JHM), defined as an increased range of joint motion, is a frequent somatic trait in the general population but also the hallmark of many of the hereditary disorders of connective tissue. Ehlers-Danlos syndromes (EDS) belong to this group of diseases and are characterized by tissue fragility, skin abnormalities, and JHM. Between JHM and EDS, there are the so-called hypermobility spectrum disorders (HSD), which is an umbrella term referring to people with symptomatic JHM who do not fulfill criteria for a syndromic connective tissue disorder such as EDS. Among the variety of clinical correlates of JHM/HSD/EDS, neurodevelopmental atypisms are common although often not screened for and identified in the clinical setting. This article reviews the pertinent literature concerning neurodevelopmental conditions for which there is some evidence of an association with JHM/HSD/EDS. These include hyperactivity and attention deficit, learning, communication, and motor problems including tic disorders such as Tourette syndrome and autism spectrum disorders. Underlying mechanism hypotheses for such interconnections are also reviewed. The coexistence of connective tissue-altered conditions and neurodevelopmental atypisms increases disability in patients from an early age. Thus, increased awareness among clinicians and researchers is necessary to promote assessment, diagnosis, and develop management strategies to meet the specific needs of those affected.

Abstract
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.

Abstract
Atlanto-axial instability (AAI) is common in the connective tissue disorders, such as rheumatoid arthritis, and increasingly recognized in the heritable disorders of Stickler, Loeys-Dietz, Marfan, Morquio, and Ehlers-Danlos (EDS) syndromes, where it typically presents as a rotary subluxation due to incompetence of the alar ligament. This retrospective, IRB-approved study examines 20 subjects with Fielding type 1 rotary subluxation, characterized by anterior subluxation of the facet on one side, with a normal atlanto-dental interval. Subjects diagnosed with a heritable connective tissue disorder, and AAI had failed non-operative treatment and presented with severe headache, neck pain, and characteristic neurological findings. Subjects underwent a modified Goel-Harms posterior C1-C2 screw fixation and fusion without complication. At 15 months, two subjects underwent reoperation following a fall (one) and occipito-atlantal instability (one). Patients reported improvement in the frequency or severity of neck pain (P < 0.001), numbness in the hands and lower extremities (P = 0.001), headaches, pre-syncope, and lightheadedness (all P < 0.01), vertigo and arm weakness (both P = 0.01), and syncope, nausea, joint pain, and exercise tolerance (all P < 0.05). The diagnosis of Fielding type 1 AAI requires directed investigation with dynamic imaging. Alignment and stabilization is associated with improvement of pain, syncopal and near-syncopal episodes, sensorimotor function, and exercise tolerance.

Abstract
Purpose: The aim was to investigate, describe and analyse speech characteristics, intelligibility, orofacial function and co-existing neurodevelopmental symptoms in children with SSD of unknown origin, persisting after six years of age.Method: The study included 61 children with SSD (6-17 years) of unknown origin, referred for a speech and oral motor examination. The severity of SSD was estimated using Percentage Consonants Correct (PCC) and Percentage Vowels Correct (PVC) and assessments of resonance based on Swedish Articulation and Nasality Test (SVANTE). Orofacial function was screened using the Nordic Orofacial Test-Screening (NOT-S). Parents completed the Intelligibility in Context Scale (ICS) and a questionnaire including questions about heredity, medical and neurodevelopmental conditions, and speech development.Result: SSD varied according to PCC (8-95%) and PVC (55-100%) measurements. Percentages of co-occurring disorders included: 51% resonance deviations, 90% intelligibility issues, and 87% orofacial difficulties. The most affected orofacial domains were "Chewing and swallowing" (41%), "Masticatory muscles and jaw function" (38%) and "Sensory function" (38%). The majority (64%) had co-existing dysfunctions relating to general motor and neurodevelopmental disorders.Conclusion: Children with persistent SSD are at risk for orofacial dysfunction, general motor difficulties and other neurodevelopmental disorders and therefore should be screened for co-occurring disorders.

Abstract
A great deal of literature has drawn attention to the "complex Chiari," wherein the presence of instability or ventral brainstem compression prompts consideration for addressing both concerns at the time of surgery. This report addresses the clinical and radiological features and surgical outcomes in a consecutive series of subjects with hereditary connective tissue disorders (HCTD) and Chiari malformation. In 2011 and 2012, 22 consecutive patients with cervical medullary syndrome and geneticist-confirmed hereditary connective tissue disorder (HCTD), with Chiari malformation (type 1 or 0) and kyphotic clivo-axial angle (CXA) enrolled in the IRB-approved study (IRB# 10-036-06: GBMC). Two subjects were excluded on the basis of previous cranio-spinal fusion or unrelated medical issues. Symptoms, patient satisfaction, and work status were assessed by a third-party questionnaire, pain by visual analog scale (0-10/10), neurologic exams by neurosurgeon, function by Karnofsky performance scale (KPS). Pre- and post-operative radiological measurements of clivo-axial angle (CXA), the Grabb-Mapstone-Oakes measurement, and Harris measurements were made independently by neuroradiologist, with pre- and post-operative imaging (MRI and CT), 10/20 with weight-bearing, flexion, and extension MRI. All subjects underwent open reduction, stabilization occiput to C2, and fusion with rib autograft. There was 100% follow-up (20/20) at 2 and 5 years. Patients were satisfied with the surgery and would do it again given the same circumstances (100%). Statistically significant improvement was seen with headache (8.2/10 pre-op to 4.5/10 post-op, p < 0.001, vertigo (92%), imbalance (82%), dysarthria (80%), dizziness (70%), memory problems (69%), walking problems (69%), function (KPS) (p < 0.001). Neurological deficits improved in all subjects. The CXA average improved from 127° to 148° (p < 0.001). The Grabb-Oakes and Harris measurements returned to normal. Fusion occurred in 100%. There were no significant differences between the 2- and 5-year period. Two patients returned to surgery for a superficial wound infections, and two required transfusion. All patients who had rib harvests had pain related that procedure (3/10), which abated by 5 years. The results support the literature, that open reduction of the kyphotic CXA to lessen ventral brainstem deformity, and fusion/stabilization to restore stability in patients with HCTD is feasible, associated with a low surgical morbidity, and results in enduring improvement in pain and function. Rib harvest resulted in pain for several years in almost all subjects.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
Joint hypermobility (JH) is a common, though largely ignored physical trait with increasing clinical reverberations. A few papers suggest a link between JH and selected neurodevelopmental disorders, such as developmental coordination disorder (DCD). JH is also the hallmark of various hereditary connective tissue disorders (HCTDs). Children with HCTDs may present abnormal neurodevelopment but its manifestations remain undetermined. This study examined 23 children (group 1), aged 4-13 years, with different HCTDs (i.e., 19 with hypermobile Ehlers-Danlos syndrome (EDS)/hypermobility spectrum disorder, 3 with molecularly confirmed classical EDS, and 1 with Loeys-Dietz syndrome type 1 due to TGFBR2 mutation) and 23, age- and sex-matched children with DCD (group 2). All underwent 14 different psychometric tests exploring motor, cognitive, executive-attentive, and emotional-behavior features. In group 1, 30%, 22%, and 13% patients presented DCD (with or without dysgraphia), learning disabilities, and attention deficit-hyperactivity disorder, respectively. None had cognitive delay. In group 2, 17% patients presented generalized JH and none had HCTDs. DCD children presented more motor and coordination troubles than HCTDs patients, while quality of life of children with HCTDs resulted more deteriorated due to somatic manifestations and behavioral traits. This study presents the full overview of neurodevelopmental attributes in HCTDs, and compares with standardized tools the neurodevelopmental profile of children with DCD and HCTDs. While the high rate of neurodevelopmental comorbidities in HCTDs deserves attention, the impact of a dysfunctional connective tissue in children with a primary diagnosis of DCD needs more research.

Abstract
INTRODUCTION Joint hypermobility (JH) is the hallmark of many hereditary soft connective tissue disorders, including Ehlers-Danlos syndromes and related disorders, disorders of the TGFβ-pathway, lateral meningocele syndrome, arterial tortuosity syndrome, and cutis laxa syndromes. Contemporary practice separates individuals with isolated, non-syndromic JH from patients with Mendelian syndromes and those with hypermobility spectrum disorders. The latter is a new nosologic entity grouping together individuals with JH and related musculoskeletal manifestations, but lacking inclusion criteria for well-defined and/or single-gene disorders. Area covered: Nomenclature of JH and JH-related disorders are summarized on a practically oriented perspective. Critical areas of clinical management comprise pain; cardiovascular and respiratory issues; fatigue and dysautonomia; bone fragility; and capillary, skin and soft tissue fragility. Medical management stands on low-evidence data. Ongoing preclinical and clinical studies are aimed to reach a more personalized pharmacological approach to the management of the cardiovascular risk, musculoskeletal pain, and reduced bone mass. Expert commentary: Correct classification of patients with JH-related disorders needs a systematic approach, in which a wide array of molecular tests should be intermingled with strong clinical competences in highly specialized settings. A multispecialty, hierarchical approach should be encouraged for optimal coordination of care in systemic phenotypes.

Abstract
Attention-deficit/hyperactivity disorder (ADHD) and generalized joint hypermobility (JH) are two separated conditions, assessed, and managed by different specialists without overlapping interests. Recently, some researchers highlighted an unexpected association between these two clinical entities. This happens in a scenario of increasing awareness on the protean detrimental effects that congenital anomalies of the connective tissue may have on human health and development. To review pertinent literature to identify possible connections between ADHD and GJH, special emphasis was put on musculoskeletal pain and syndromic presentations of GJH, particularly the hypermobile Ehlers-Danlos syndrome. A comprehensive search of scientific databases and references lists was conducted, encompassing publications based on qualitative and quantitative research. Impaired coordination and proprioception, fatigue, chronic pain, and dysautonomia are identified as potential bridges between ADHD and JH. Based on these findings, a map of the pathophysiological and psychopathological pathways connecting both conditions is proposed. Although ADHD and JH are traditionally separated human attributes, their association may testify for the dyadic nature of mind-body connections during critical periods of post-natal development. Such a mixed picture has potentially important consequences in terms of disability and deserves more clinical and research attention.

Abstract
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.

Abstract
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.

Abstract
There is increasing amount of evidence pointing toward a high prevalence of psychiatric conditions among individuals with hypermobile type of Ehlers-Danlos syndrome (JHS/hEDS). A literature review confirms a strong association between anxiety disorders and JHSh/hEDS, and there is also limited but growing evidence that JHSh/hEDS is also associated with depression, eating, and neuro-developmental disorders as well as alcohol and tobacco misuse. The underlying mechanisms behind this association include genetic risks, autonomic nervous system dysfunction, increased exteroceptive and interoceptive mechanisms and decreased proprioception. Recent neuroimaging studies have also shown an increase response in emotion processing brain areas which could explain the high affective reactivity seen in JHS/hEDS. Management of these patients should include psychiatric and psychological approaches, not only to relieve the clinical conditions but also to improve abilities to cope through proper drug treatment, psychotherapy, and psychological rehabilitation adequately coupled with modern physiotherapy. A multidimensional approach to this "neuroconnective phenotype" should be implemented to ensure proper assessment and to guide for more specific treatments. Future lines of research should further explore the full dimension of the psychopathology associated with JHS/hEDS to define the nature of the relationship. © 2017 Wiley Periodicals, Inc.

Abstract
Infants born at extreme preterm gestation are at risk for both death and disability. Although rates of survival have improved for this population, and some evidence suggests a trend toward decreased neuromotor impairment over the past decades, a significant improvement in overall early neurodevelopmental outcome has not yet been realized. This review will examine the rates and types of neurodevelopmental impairment seen after extremely preterm birth, including neurosensory, motor, cognitive, and behavioral outcomes. We focus on early outcomes in the first 18-36 months of life, as the majority of large neonatal studies examining neurodevelopmental outcomes stop at this age. However, this early age is clearly just a first glimpse into lifetime outcomes; the neurodevelopmental effects of extreme prematurity may last through school age, adolescence, and beyond. Importantly, prematurity appears to be an independent risk factor for adverse development, but this population demonstrates considerable variability in the types and severity of impairments. Understanding both the nature and prevalence of neurodevelopmental impairment among extremely preterm infants is important because it can lead to targeted interventions that in turn may lead to improved outcomes.

Abstract
We investigated the purported association between developmental changes in grip selection planning and improvements in an individual’s capacity to represent action at an internal level [i.e., motor imagery (MI)]. Participants were groups of healthy children aged 6–7 years and 8–12 years respectively, while a group of adolescents (13–17 years) and adults (18–34 years) allowed for consideration of childhood development in the broader context of motor maturation. A group of children aged 8–12 years with probable DCD (pDCD) was included as a reference group for atypical motor development. Participants’ proficiency to generate and/or engage internal action representations was inferred from performance on the hand rotation task, a well-validated measure of MI. A grip selection task designed to elicit the end-state comfort (ESC) effect provided a window into the integrity of grip selection planning. Consistent with earlier accounts, the efficiency of grip selection planning followed a non-linear developmental progression in neurotypical individuals. As expected, analysis confirmed that these developmental improvements were predicted by an increased capacity to generate and/or engage internal action representations. The profile of this association remained stable throughout the (typical) developmental spectrum. These findings are consistent with computational accounts of action planning that argue that internal action representations are associated with the expression and development of grip selection planning across typical development. However, no such association was found for our sample of children with pDCD, suggesting that individuals with atypical motor skill may adopt an alternative, sub-optimal strategy to plan their grip selection compared to their same-age control peers.

Abstract
Developmental coordination disorder (DCD) is a recognized childhood disorder mostly characterized by motor coordination difficulties. Joint hypermobility syndrome, alternatively termed Ehlers-Danlos syndrome, hypermobility type (JHS/EDS-HT), is a hereditary connective tissue disorder mainly featuring generalized joint hypermobility (gJHM), musculoskeletal pain, and minor skin features. Although these two conditions seem apparently unrelated, recent evidence highlights a high rate of motor and coordination findings in children with gJHM or JHS/EDS-HT. Here, we investigated the prevalence of gJHM in 41 Italian children with DCD in order to check for the existence of recognizable phenotypic subgroups of DCD in relation to the presence/absence of gJHM. All patients were screened for Beighton score and a set of neuropsychological tests for motor competences (Movement Assessment Battery for Children and Visual-Motor Integration tests), and language and learning difficulties (Linguistic Comprehension Test, Peabody Picture Vocabulary Test, Boston Naming Test, Bus Story Test, and Memoria-Training tests). All patients were also screening for selected JHS/EDS-HT-associated features and swallowing problems. Nineteen (46%) children showed gJHM and 22 (54%) did not. Children with DCD and gJHM showed a significant excess of frequent falls (95 vs. 18%), easy bruising (74 vs. 0%), motor impersistence (89 vs. 23%), sore hands for writing (53 vs. 9%), attention deficit/hyperactivity disorder (89 vs. 36%), constipation (53 vs. 0%), arthralgias/myalgias (58 vs. 4%), narrative difficulties (74 vs. 32%), and atypical swallowing (74 vs. 18%). This study confirms the non-causal association between DCD and gJHM, which, in turn, seems to increase the risk for non-random additional features.

Abstract
Joint hypermobility syndrome/Ehlers-Danlos syndrome hypermobility type (JHS/EDS-HT) is a hereditary connective tissue disorder affecting every bodily system. It is largely underdiagnosed by many practitioners, with the result of a considerable delay in diagnosis and, consequently, in the onset of adequate management schedule and treatment. Patients may also experience to be misbelieved, erroneously considered affected by a psychiatric or psychosomatic disorders, and rejected by the medical profession, which can lead to feelings of anger and resentment. Patient journeys are often long and complicated, but if doctors allowed the patient time to tell the full story, and were more prepared to think holistically, there may be a far more positive outcome. Here, the patients' perspective is presented with a narrative medicine approach, illustrating the tri-dimensional experience of a JHS/EDS-HT patient, who is also a Bowen Practitioner and a medical writer/educator. Narrative medicine would be invaluable in working with JHS/EDS-HT so that the patient can tell the story, and offer the practitioner a whole picture of her/his suffering and, often, the key for understanding the cause(s). Once this has been achieved, it might be possible to build upon a more positive and therapeutic dialogue which would result in better treatment and more effective management. It is also important for doctors to communicate with JHS/EDS-HT experts who will ultimately improve the patient journey and treatment outcomes of such a complex connective tissue disorder.

Abstract
Among developmental disorders, DCD is one of the least studied and less understood one (Bishop, 2010). This review summarizes the current understanding of developmental coordination disorder in neuropsychology with a focus mainly on high level sensorimotor impairments, its etiology and its neural bases. We summarize these core deficits in the framework of an influent motor control model (Blakemore et al., 2002). DCD has several environmental risk factors which probably interplay with genetic factors but those have not been sufficiently identified. High-level sensori-motor deficits are probably multifactorial in DCD and involve predictive coding deficits as well as weaknesses in perceptual and sensory integration. At the brain level, DCD is associated with impaired structure and functions within the motor network. Throughout the review we highlight exciting new findings as well as potential future lines of research to provide a more comprehensive understanding of this disorder.

J Pediatr 2015; 167:694-701.e1. [PMID: 26190232 DOI: 10.1016/j.jpeds.2015.06.034] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2014] [Revised: 05/28/2015] [Accepted: 06/17/2015] [Indexed: 11/27/2022]
Abstract
OBJECTIVE To determine the prevalence of generalized joint hypermobility (GJH) in Dutch children aged 5.5 years, and to examine the association between GJH and motor performance and development over time. STUDY DESIGN A prospective cohort of 249 children was recruited. GJH was assessed with the Beighton test at age 5.5 years. Motor performance was evaluated at age 2.0 years using the Bayley Scales of Infant Development, Second Edition and at age 5.5 years using the Movement Assessment Battery for Children-Second Edition (subscore categories: manual dexterity, aiming and catching, and static and dynamic balance). RESULTS In 249 children, the prevalence of GJH, defined by the Beighton test score, was 34.1% for a score ≥ 4, 22.5% for a score ≥ 5, and 16.5% for a score ≥ 6. No significant association was found between GJH and total motor performance. Manual dexterity in girls (Beighton score ≥ 4) was positively associated with higher level of motor performance (β [SE] = 0.38 [0.17]; P = .028), ranging from +0.04 SD to +0.72 SD, even after correction for covariates. A significant interaction between GJH and body mass index (BMI) growth was found, indicating that the effect of GJH on the rate of development of motor performance declines with increasing BMI growth (β = 0.05 [0.02]; P = .031). CONCLUSION In this healthy pediatric cohort, GJH was present in one-third of the sample, and no significant association was found between GJH and total motor performance. The effect of GJH on the rate of development of motor performance appears to decline with increasing BMI growth. Longitudinal prospective studies are recommended to detect influences of GJH on motor performance over time, as well as the influence of body composition and Beighton cutoff points.

Abstract
This review explores the proposal that vulnerability to psychological symptoms, particularly anxiety, originates in constitutional differences in the control of bodily state, exemplified by a set of conditions that include Joint Hypermobility, Postural Tachycardia Syndrome and Vasovagal Syncope. Research is revealing how brain-body mechanisms underlie individual differences in psychophysiological reactivity that can be important for predicting, stratifying and treating individuals with anxiety disorders and related conditions. One common constitutional difference is Joint Hypermobility, in which there is an increased range of joint movement as a result of a variant of collagen. Joint hypermobility is over-represented in people with anxiety, mood and neurodevelopmental disorders. It is also linked to stress-sensitive medical conditions such as irritable bowel syndrome, chronic fatigue syndrome and fibromyalgia. Structural differences in “emotional” brain regions are reported in hypermobile individuals, and many people with joint hypermobility manifest autonomic abnormalities, typically Postural Tachycardia Syndrome. Enhanced heart rate reactivity during postural change and as recently recognized factors causing vasodilatation (as noted post-prandially, post-exertion and with heat) is characteristic of Postural Tachycardia Syndrome, and there is a phenomenological overlap with anxiety disorders, which may be partially accounted for by exaggerated neural reactivity within ventromedial prefrontal cortex. People who experience Vasovagal Syncope, a heritable tendency to fainting induced by emotional challenges (and needle/blood phobia), are also more vulnerable to anxiety disorders. Neuroimaging implicates brainstem differences in vulnerability to faints, yet the structural integrity of the caudate nucleus appears important for the control of fainting frequency in relation to parasympathetic tone and anxiety. Together there is clinical and neuroanatomical evidence to show that common constitutional differences affecting autonomic responsivity are linked to psychiatric symptoms, notably anxiety.

Abstract
OBJECTIVE The heritable disorders of connective tissue (HDCTs) are a group of genetic disorders affecting connective tissue matrix proteins. Fragility, laxity of tissues and joint hypermobility (JH) are commons features of HDCT for which the prognosis may range from benign to life threatening. JH and HDCTs, especially joint hypermobility syndrome, Ehlers-Danlos syndromes and Marfan syndrome, have been associated with psychiatric symptomatology. We explored the existing knowledge concerning this association in order to provide an overview of mental disorders linked to JH/HDCT, as well as the hypotheses proposed to explain such association. METHOD A comprehensive search of scientific online databases and references lists was conducted, encompassing publications based on quantitative and qualitative research, including case reports. RESULTS Psychiatric conditions in which there is some evidence of an association with JH/HDCT are anxiety disorders, depression, schizophrenia, neurodevelopmental disorders (autism, attention deficit/hyperactivity disorder, and developmental coordination disorder), eating disorders, personality disorders and substance use/misuse. CONCLUSION Despite the need of more research, the available data highlight the importance of examining psychiatric symptoms in those affected by JH/HDCT and the importance of providing interventions with a multidisciplinary approach. The relationship between JH/HDCT and mental disorders merits further attention in order to improve current knowledge and clarify a possible common etiology.

Abstract
BACKGROUND There is some evidence that indicates generalized joint hypermobility (GJH) is a risk factor for pain persistence and recurrence in adolescence. However, how early pain develops and whether GJH without pain in childhood is a risk factor for pain development in adolescence is undetermined. The aims for this study were to investigate the association between GJH and development of joint pain and to investigate the current GJH status and physical function in Danish adolescents. METHODS This was a longitudinal cohort study nested within the Copenhagen Hypermobility Cohort. All children (n = 301) were examined for the exposure, GJH, using the Beighton test at baseline at either 8 or 10 years of age and then re-examined when they reached 14 years of age. The children were categorized into two groups based on their number of positive Beighton tests using different cut points (i.e. GJH4 defined as either < 4 or ≥ 4, GJH5 and GJH6 were similarly defined). The outcome of joint pain was defined as arthralgia as measured by the Brighton criteria from the clinical examination. Other outcome measures of self-reported physical function and objective physical function were also collected. RESULTS Children with GJH had three times higher risk of developing joint pain in adolescence, although this association did not reach statistical significance (GJH5: 3.00, 95% [0.94-9.60]). At age 14, the adolescents with GJH had significantly lower self-reported physical function (for ADL: GJH4 p = 0.002, GJH5 p = 0.012; for pain during sitting: GJH4 p = 0.002, GJH5 p = 0.018) and had significantly higher body mass index (BMI: GJH5 p = 0.004, GJH6 p = 0.006) than adolescents without GJH. There was no difference in measured physical function. CONCLUSION This study has suggested a possible link between GJH and joint pain in the adolescent population. GJH was both a predictive and a contributing factor for future pain. Additional studies with larger sample sizes are needed to confirm our findings.

Abstract
Developmental coordination disorder (DCD) affects around 5% of children and commonly overlaps with other developmental disorders including: attention deficit hyperactivity disorder (ADHD), autism spectrum disorders (ASDs) and specific language impairment (SLI). There is evidence to demonstrate the wide-ranging impact on all areas of functioning including psychiatric and learning domains. There is increasing evidence of the continuing impact into adulthood and the long-term negative effects on relationships and employment. There is a need for early identification and intervention to limit the likelihood of these secondary consequences from emerging. This paper addresses the diagnosis of DCD.

Abstract
UNLABELLED Voiding dysfunction is a common entity in pediatric urology. It is believed to have a multifactorial etiology. The aim of this study was to investigate whether there is an increased prevalence of generalized joint hypermobility (GJH) in children with voiding dysfunction compared to normal children. Moreover, the prevalence of voiding complaints in patients with and without GJH was assessed. A total of 226 children--aged 5 to 14 years--including 113 patients diagnosed with voiding dysfunction and 113 sex/age/body mass index-matched normal children were recruited. GJH was evaluated in both groups using the Beighton score (4 or more= hypermobile). In the patient’s group, GJH was significantly more frequent than in controls: 51/113 (45 %) versus 19/113 (17 %) (P=0.001). In addition, in both groups, GJH was more prominent in girls than boys (P<0.05). Urinary tract infection was the most frequent features in children with voiding dysfunction (64 %). In the subgroup of positive GJH, urinary tract infection remained the most common manifestation among the girls (P=0.003), while constipation was the most prevalent manifestation among the boys (P=0.001). CONCLUSION Our findings suggest that children with voiding dysfunction have significantly higher prevalence of GJH compared to normal children. Further studies are needed to determine the cause and effect of these two common presentations and will help to develop a multidisciplinary approach in understanding and management of voiding dysfunction in children.

Abstract
There has been minimal evidence examining the differences in submaximal aerobic power between children with and without probable developmental coordination disorder (pDCD). This is important as most activities of daily living are performed at submaximal levels. The aim of this study was to examine the oxygen cost of work (VO2) performed during an incremental exercise protocol on a cycle ergometer. Subjects with pDCD (n=63) were matched for age and gender to 63 typically developing controls (12-13 years of age) using a nested case-control design. Motor coordination was assessed using the Movement Assessment Battery for Children. Children with pDCD had significantly lower VO2 peak values relative to controls (35.0 vs. 42.9 ml/kg/min, p<0.0001). At the submaximal level, mixed effects modeling demonstrated that, after controlling for relative body fat, and VO2 peak, children with pDCD had consistently greater oxygen cost (VO2 ml/kg/min) compared to controls at any given exercise intensity (p=0.0006). A significant interaction between pDCD and workload indicated that the difference in VO2 at higher workloads is greater than that at lower workloads (p=0.0004). Children with pDCD utilize more oxygen to sustain the same submaximal workload. The implication of these findings is that children with pDCD may experience earlier fatigue than well coordinated individuals when engaging in physical activity.

Abstract
Developmental Coordination Disorder (DCD) is a neurodevelopmental disorder characterised by impaired motor co-ordination and awkward gait. Despite self-reported findings of pes planus and joint hypermobility in children with DCD, there is little objective evidence regarding the clinical management of the foot in children with DCD. The aims of this research were to report clinical findings of foot posture and lower limb hypermobility in children with DCD and to evaluate the impact of foot orthoses on spatio-temporal gait parameters. Children with DCD were recruited into the study. Participants were randomly assigned to an intervention group who received foot orthoses at the start of their rehabilitation programme or to a second group who received foot orthoses at the end of their intervention programme. Foot posture was assessed with the Foot Posture Index and lower limb hypermobility assessed with the Lower Limb Assessment Score. The effect of foot orthoses was evaluated through assessment of spatio-temporal gait characteristics at baseline and post-rehabilitation programme. Fourteen children were recruited (mdn age 7.5 years) with nine children assigned to the group receiving orthoses early (mdn age 8 years) and five children assigned to the post-rehabilitation orthoses group (mdn age 6.5 years). A pes planus foot posture (FPI score=8) and lower limb hypermobility (LLAS score=11) were observed. Changes in spatio-temporal gait parameters failed to reach significance (p>.012) following orthotic invention but demonstrated a trend towards a decreased cadence and increased double support duration. Despite non-significant findings this work offers preliminary support for podiatric intervention in the rehabilitation of children with DCD. Further work is required to understand the biomechanics of gait in children with DCD and appreciate the role of podiatry as a component of multidisciplinary care.

Abstract
Children with Developmental Coordination Disorder (DCD) often have difficulties running. This study compared strategies of propulsion and power generation at the ankle during late stance/early swing in both walking and running in children with and without DCD. Eleven children (six male) aged nine to 12 years with DCD were matched by sex and age with 11 typically developing (TD) children. Gait kinematics and kinetics were measured during 4 gait types; normal walking, fast walking, jogging and sprinting using three-dimensional motion analysis. Propulsion strategy during gait was calculated as ankle power divided by the sum of ankle and hip power (A2/A2+H3). The children with DCD ran slower than the TD children (mean difference [MD] when jogging 0.3m/s and sprinting 0.8m/s). Adjusting for speed, those with DCD had smaller propulsion strategy values during jogging (p=0.001) and sprinting (p=0.012), explained by reduced ankle power generation at push off (A2) (jogging, MD 2.5 W/kg, p<0.001) and greater hip flexor power generation at pull off (H3) (jogging, MD 0.75 W/kg, p=0.013). Similar findings were observed during sprinting. Children with DCD ran with a slow and less efficient running style compared with TD children. Physiotherapy targeting running-specific needs in relation to ankle muscle strength and coordination could enable more participation in running activities.

The relationship between joint mobility and motor performance in children with and without the diagnosis of developmental coordination disorder. BMC Pediatr 2013; 13:35. [PMID: 23497034 PMCID: PMC3605363 DOI: 10.1186/1471-2431-13-35] [Citation(s) in RCA: 30] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2012] [Accepted: 03/08/2013] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND The purpose of this study was to determine whether joint mobility is associated with motor performance in children referred for Developmental Coordination Disorder (DCD-group) in contrast to a randomly selected group of children between 3-16 years of age (Random-Group). METHODS 36 children with DCD and 352 typically developing children (Random-Group) participated. Hypermobility was classified based on the Beighton score (cut-off ≥5 for 3-9 years and ≥4 for 10-16 years) using goniometry. Motor performance was assessed with the Movement Assessment Battery for Children (MABC). RESULTS The mean Beighton score in the DCD-group was 5.0 versus 2.6 in the Random group. Prevalence of hypermobility was higher in the DCD-group than in the Random Group (64% and 33% respectively; χ2 = 16.09, p < .001). There was a significant [negative] correlation (r(p) = -.38, p = .02) between Beighton score and total MABC scores within the DCD group, but not in the Random Group (r(p)= -0.07, p = .20). More specifically, in the DCD group we found a significant negative correlation between the MABC total score and the degree of hyperextension of the knees. CONCLUSION The extremely high prevalence of hypermobility when applying the recommended cut-off scores stresses the need for an international agreement on firm cut-off points and the use of standardized measurement of Beighton mobility manoeuvres. The results of this study show that a cut-off of 7 is more appropriate, resulting in a prevalence of 6% in children aged 3-16 years. Although in the general population motor performance and joint mobility are not related, this is the case in children referred for DCD. We argue that more mobility of the joints may be a disadvantage when motor coordination is poorly developed.

Abstract
Ehlers-Danlos syndrome, hypermobility type, constituting a phenotypic continuum with or, perhaps, corresponding to the joint hypermobility syndrome (JHS/EDS-HT), is likely the most common, though the least recognized, heritable connective tissue disorder. Known for decades as a hereditary condition with predominant rheumatologic manifestations, it is now emerging as a multisystemic disorder with widespread manifestations. Nevertheless, the practitioners' awareness of this condition is generally poor and most patients await years or, perhaps, decades before reaching the correct diagnosis. Among the various sites of disease manifestations, skin and mucosae represent a neglected organ where the dermatologist can easily spot diagnostic clues, which consistently integrate joint hypermobility and other orthopedic/neurologic manifestations at physical examination. In this paper, actual knowledge on JHS/EDS-HT is summarized in various sections. Particular attention has been posed on overlooked manifestations, including cutaneous, mucosal, and oropharyngeal features, and early diagnosis techniques, as a major point of interest for the practicing dermatologist. Actual research progresses on JH/EDS-HT envisage an unexpected link between heritable dysfunctions of the connective tissue and a wide range of functional somatic syndromes, most of them commonly diagnosed in the office of various specialists, comprising dermatologists.

Abstract
Joint hypermobility syndrome (JHS), or Ehlers-Danlos syndrome (EDS) hypermobility type (EDS-HT), is a underdiagnosed heritable connective tissue disorder characterized by generalized joint hypermobility and a wide range of visceral, pelvic, neurologic, and cognitive dysfunctions. Deterioration of quality of life is mainly associated with pain and fatigue. Except for the recognized effectiveness of physiotherapy for some musculoskeletal features, there are no standardized guidelines for the assessment and treatment of pain and fatigue. In this work, a practical classification of pain presentations and factors contributing in generating painful sensations in JHS/EDS-HT is proposed. Pain can be topographically classified in articular limb (acute/subacute and chronic), muscular limb (myofascial and fibromyalgia), neuropathic limb, back/neck, abdominal and pelvic pain, and headache. For selected forms of pain, specific predisposing characteristics are outlined. Fatigue appears as the result of multiple factors, including muscle weakness, respiratory insufficiency, unrefreshing sleep, dysautonomia, intestinal malabsorption, reactive depression/anxiety, and excessive use of analgesics. A set of lifestyle recommendations to instruct patients as well as specific investigations aimed at characterizing pain and fatigue are identified. Available treatment options are discussed in the set of a structured multidisciplinary approach based on reliable outcome tools.

Abstract
OBJECTIVE To evaluate the validity of the Beighton score as a generalized measure of hypermobility and to measure the prevalence of hypermobility and pain in a random population of school age children. STUDY DESIGN Prospective study of 551 children attending various Dutch elementary schools participated; 47% were males (258) and 53% (293) females, age range was 6 to 12 years. Children's joints and movements were assessed according to the Beighton score by qualified physiotherapists and by use of goniometry measuring 16 passive ranges of motion of joints on both sides of the body. RESULTS More than 35% of children scored more than 5/9 on the Beighton score. Children who scored high on the Beighton score also showed increased range of motion in the other joints measured. Moreover 12.3% of children had symptoms of joint pain, and 9.1% complained of pain after exercise or sports. Importantly, this percentage was independent of the Beighton score. There were no significant differences in Beighton score for sex in this population. CONCLUSION The Beighton score, when goniometry is used, is a valid instrument to measure generalized joint mobility in school-age children 6 to 12 years. No extra items are needed to improve the scale.

Abstract
Evidence suggests that developmental coordination disorder (DCD) co-occurs with attention deficit hyperactivity disorder (ADHD) and joint hypermobility syndrome (JHS). Paediatric occupational therapists working with children with DCD need to consider the impact of co-occurring conditions on the children they assess and treat. A survey investigating the knowledge base and understanding relating to these conditions was conducted. The results showed that therapists (n = 225, response rate 23%) have an understanding of DCD; however, a more detailed knowledge of ADHD and JHS would allow them to consider the impact of the overlapping nature of these conditions. This highlights a training need to ensure understanding of these conditions and appropriate management.

Abstract
OBJECTIVE Because the criteria used for diagnosing between generalized joint hypermobility (GJH) and musculoskeletal complaints, as well as relations between GJH and an insufficient motor development and/or a reduced physical activity level differ, the prevalence of GJH varies considerably. The aim of this study was to survey the prevalence of GJH defined by a Beighton score at >or=4, >or=5, or >or=6 positive tests of 9 and benign joint hypermobility syndrome (BJHS) in Danish primary school children at 8 years of age. A second aim was to compare children with and without GJH and BJHS regarding motor competence, self-reported physical activity, and incidence of musculoskeletal pain and injuries. METHODS A cross-sectional study of 524 children in the second grade from 10 public schools was performed. A positive response rate was obtained for 416 (79.4%) children, and 411 (78.4%) children were clinically examined and tested for motor competence, whereas questionnaire response to items comprising musculoskeletal pain and injuries, in addition to daily level and duration of physical activity, corresponded to 377 (71.9%) children. RESULTS In total, 29% of the children had GJH4, 19% had GJH5, 10% had GJH6, and 9% had BJHS, with no gender difference. There was no difference in daily level and duration of physical activity and in frequency of musculoskeletal pain and injuries between those with and without GJH. Children with >or=GJH5 as well as with >or=GJH6 performed better in the motor competence tests. CONCLUSION Motor competence and physical activity are not reduced in primary school children at 8 years of age with GJH or BJHS. It is recommended that a potential negative influence on the musculoskeletal system over time, as a result of GJH, be investigated by longitudinal studies.
