INTRODUCTION: Lowered pressure pain thresholds have been demonstrated in adults with Ehlers-Danlos Hypermobility type(EDS-HT), however it remains unclear if these findings are also present in children. Therefore, the objectives of the study were to: (1)determine if generalized hyperalgesia is present in Hypermobility syndrome (HMS)/EDS-HT children, (2)explore potential differences in pressure pain thresholds between HMS/EDS-HT children and adults, and (3)determine the discriminative value of generalized hyperalgesia.METHODS: Patients classified in one of three groups: HMS/EDS-HT, hypermobile (Beighton score ≥4/9) and healthy controls. Descriptive data of age, gender, body mass index, Beighton score, skin laxity and medication usage were collected. Generalized hyperalgesia was quantified by the averaged pressure pain thresholds collected from 12 locations. The following confounders were collected: pain locations/intensity, fatigue, psychological distress. Comparisons between HMS/EDS-HT children and normative values, between children and adults with HMS/EDS-HT, corrected confounders, were analysed with MANCOVA. The discriminative value of generalized hyperalgesia employed in order to differentiate between HMS/EDS-HT, hypermobile and controls was quantified with logistic regression.RESULTS: Significantly lower pressure pain thresholds were found in children with HMS/EDS-HT compared to normative values (range: -22.0% to -59.0%, p=<.05). When applying a threshold of 30.8 N/cm(2) for males and 29.0 N/cm(2) for females, the presence of generalized hyperalgesia discriminated between individuals with HMS/EDS-HT, hypermobile and healthy controls (odds ratio=6.0).CONCLUSION: Children and adults with HMS/EDS-HT are characterized by hypermobility, chronic pain, as well as generalized hyperalgesia. The presence of generalized hyperalgesia may indicate involvement of the central nervous system in the development of chronic pain. This article is protected by copyright. All rights reserved.
The aim of the present study was to investigate the nature and prevalence of nonspecific somatic symptoms, pain and catastrophizing in children with Heritable Connective Tissue Disorders (HCTD), and to determine their association with disability. This observational, multicenter study included 127 children, aged 4–18 years, with Marfan syndrome (MFS) (59%), Loeys-Dietz syndrome (LDS) (8%), Ehlers-Danlos syndromes (EDS) (12%) and hypermobile Ehlers-Danlos syndrome (hEDS) (23%). The assessments included the Children's Somatization Inventory or parent proxy (CSI, PCSI), pain visual-analogue scale (VAS), SUPERKIDZ body diagram, Pain Catastrophizing Scale Child or parent proxy (PCS-C, PCS-P) and Childhood Health Assessment Questionnaire (CHAQ-30). Data from children aged ≥8 years were compared to normative data. In children ≥ 8 years (n = 90), pain was present in 59%, with a median of 4 (IQR = 3–9) pain areas. Compared to normative data, the HCTD group reported significantly higher on the CSI (p ≤ 0.001, d = 0.85), VAS pain intensity (p ≤ 0.001, d = 1.22) and CHAQ-30 (p ≤ 0.001, d = 1.16) and lower on the PCS-C (p = 0.017, d = −0.82) and PCS-P (p ≤ 0.001, d = −0.49). The intensity of nonspecific somatic symptoms and pain explained 45% of the variance in disability (r2 = 0.45 F(2,48) = 19.70, p ≤ 0.001). In children ≤ 7 years (n = 37), pain was present in 35% with a median of 5(IQR = 1–13) pain areas. The mean(SD) VAS scores for pain intensity was 1.5(2.9). Functional disability was moderately correlated to the number of pain areas (r = 0.56, p ≤ 0.001), intensity of nonspecific somatic symptoms (r = 0.63, p ≤ 0.001) and pain (r = 0.83, p ≤ 0.001). In conclusion, this study supports the need for comprehensive assessment of nonspecific somatic symptoms, pain, and disability in children with HCTD to allow tailored treatment.
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.
