Study Type – Aetiology (individual cohort)Level of Evidence 2bWhat's known on the subject? and What does the study add?Recent studies have already shown associations between generalized joint hypermobility (GJH) and voiding and defecation dysfunction and/or slow transit constipation. Changes in extracellular matrix composition in vesico‐ureteric junction of vesico‐ureteral reflux (VUR) patients were also observed previously.This study is the first to assess joint mobility as a parameter for connective tissue composition in vesico‐ureteral reflux. We convincingly demonstrate that VUR patients have significantly more hypermobile joints compared to controls and this provides a new angle to the intriguing subjects of development of VUR and susceptibility to VUR.OBJECTIVE•To assess whether there is an increased prevalence of joint hypermobility in patients with vesico‐ureteric reflux (VUR).MATERIALS AND METHODS•We studied 50 patients with primary VUR and matched controls drawn from a reference population.•Joint mobility was assessed using the Bulbena hypermobility score.RESULTS•We identified significantly more patients with VUR with generalized joint hypermobility than controls (24% vs 6.7%, P= 0.007).CONCLUSION•Our findings confirm our clinical observation of an increased rate of joint hypermobility in patients with VUR. We speculate that an altered composition of the connective tissue may contribute to the severity of the (pre‐existing) VUR phenotype.

Background: Generalized Joint Hypermobility (GJH) is regarded as the main diagnostic criterion for Hypermobility Syndrome and is assumed to be of importance for the development of musculoskeletal complaints and functional decline. However GJH is also highly prevalent amongst healthy individuals whereas its consequences for physical functioning are unclear. Therefore the objective of the study was to determine the association of GJH with physical functioning in healthy adolescents and young adults.Methods: 328 participants (mean age (sd): 20.2 (1.8), gender (male/female): 134/194) were included. In order to establish the effect of GJH, subjects with symptomatic forms of GJH were excluded, as were subjects with other conditions that could influence physical functioning. Age, gender, BMI, GJH, muscle strength and physical activity level (PAL) in METS were collected.Results: GJH was associated with reduced muscle strength for all muscle groups (p=<.05), controlled for age and BMI. Ranging from -0.7 to -1.0SD in females and -.3 to -1.3SD in males. GJH was found to be significantly associated with higher amounts of METS spent on cycling, ranging from +0.2 to +0.9SD in females (p=.002) and +0.3 to +0.9SD in males (p=.041), where lower amounts of METS spent on sports activities was observed, ranging from -0.4 to -1.2SD in females (p=.002) and -0.2 to -1.9SD in males (p=.004).Conclusion: Individuals with GJH have reduced muscle strength and tend to avoid dynamic activities and prefer more stable activities, like cycling. This may indicate that individuals with GJH adapt their behaviour to prevent musculoskeletal complaints and functional decline.

Young professional dancers find themselves in a demanding environment. GJH within dancers is often seen as aesthetically beneficial and a sign of talent but was found to be potentially disabling. Moreover, high-performing adolescents and young adults (HPAA), in this specific lifespan, might be even more vulnerable to anxiety-related disability. Therefore, we examined the development of the association between the presence of Generalized Joint Hypermobility (GJH) and anxiety within HPAA with a one-year follow-up. In 52.3% of the HPAA, anxiety did not change significantly over time, whereas GJH was present in 28.7%. Fatigue increased significantly in all HPAA at one year follow-up (respectively, females MD (SD) 18(19), p < 0.001 and males MD (SD) 9(19), p < 0.05). A significantly lower odds ratio (ß (95% CI) 0.4 (0.2–0.9); p-value 0.039) for participating in the second assessment was present in HPAA with GJH and anxiety with a 55% dropout rate after one year. This confirms the segregation between GJH combined with anxiety and GJH alone. The fatigue levels of all HPAA increased significantly over time to a serious risk for sick leave and work disability. This study confirms the association between GJH and anxiety but especially emphasizes the disabling role of anxiety. Screening for anxiety is relevant in HPAA with GJH and might influence tailored interventions.
