“…The results of muscular torque also contradict Juul et al, 2012 [24], who studied a large number of independent variables [age, gender, pain, activity level, beside GJH] and its effect on also a large number of dependent variables. They only found that, girls with non-symptomatic GJH had reduced isokinetic normalized PT knee extension [eccentrically].…”

“…Thus, the coactivation strategy seems to be task-dependent as Jensen et al 2013, [27], said. On the other hand, Juul-Kristensen, 2012 [24], disagree with us when he did his study about Knee function in 10-year-old children with generalized joint Hypermobility, as he said that, there is no significant difference in H/Q ratio between normal children and children with generalized joint hypermobility.…”

Purpose: the current study intended to investigate the effect of hypermobility on the hamstring's muscular torque, quadriceps' muscular torque and H/Q ratio.Materials and Methods: thirty normal male children aged from seven to eleven years and thirty age-matched male children with GJH were tested using isokinetic dynamometer. Eccentric-concentric and concentric eccentric moods were used for hamstring and quadriceps respectively at angular velocity of 60°/s.Results: the results exposed that there was significant decrease in both peak muscular torques and H/Q ratio in children with GJH when they were compared with normal children [P < .05]. Conclusion:it can be concluded that joint hypermobility decreases muscular torque and H/Q ratio. This may be due to proprioceptive deficits associated with hypermobility and abnormal muscular activation pattern. Further studies are needed to verify the definite cause of decreased muscular torque and H/Q ratio.

“…GJH: children (10 years old) with GJH5 had significantly higher peak vertical jump height, without a significant correlation between Beighton score and jump height, while there was no higher rate of force development in GJH5 [50]. A similar result was found in girls with GJH6 who had an insignificantly higher vertical jump height compared with girls without GJH, and significantly positive correlations between Beighton score and vertical jump height [8].…”

“…Other case-control studies did not confirm reduced isometric or isokinetic knee extension and flexion in children with nonsymptomatic or symptomatic GJH [49, 50]. Neither was there reduced hamstrings-quadriceps (H/Q) ratio in children with GJH compared with a reference group; however, girls with nonsymptomatic GJH5 had reduced isokinetic normalised PT knee extension (eccentrically) [50]. …”

Introduction. To provide a state of the art on diagnostics, clinical characteristics, and treatment of paediatric generalised joint hypermobility (GJH) and joint hypermobility syndrome (JHS). Method. A narrative review was performed regarding diagnostics and clinical characteristics. Effectiveness of treatment was evaluated by systematic review. Searches of Medline and Central were performed and included nonsymptomatic and symptomatic forms of GJH (JHS, collagen diseases). Results. In the last decade, scientific research has accumulated on all domains of the ICF. GJH/JHS can be considered as a clinical entity, which can have serious effects during all stages of life. However research regarding the pathological mechanism has resulted in new potential opportunities for treatment. When regarding the effectiveness of current treatments, the search identified 1318 studies, from which three were included (JHS: n = 2, Osteogenesis Imperfecta: n = 1). According to the best evidence synthesis, there was strong evidence that enhancing physical fitness is an effective treatment for children with JHS. However this was based on only two studies. Conclusion. Based on the sparsely available knowledge on intervention studies, future longitudinal studies should focus on the effect of physical activity, fitness, and joint stabilisation. In JHS and chronic pain, the effectiveness of a multidisciplinary approach should be investigated.

“…A recent study found increased joint moments during walking in adults with GJH compared with adults without GJH (NGJH) [30], and adults with GJH had more pain, symptoms, trouble with daily activities, sports activities and decreased quality of life compared with healthy controls [31]. …”

BackgroundTo study differences in gait patterns in 10-year-old children with Generalized Joint Hypermobility (GJH) and with no GJH (NGJH).MethodsA total of 37 children participated (19 GJH, 18 NGJH, mean age 10.2 (SD 0.5) years). Inclusion criteria for GJH were a Beighton score of ≥5, with at least one hypermobile knee joint; for NGJH a Beighton score of ≤4, and no hypermobile knees and for both groups no knee pain during the previous week. All children were recorded by five video cameras, while they walked across three force platforms. Net joint moments were calculated in 3D by inverse dynamics and peak values provided input to statistical analyses.ResultsIn the frontal plane, children with GJH had a significantly lower peak knee abductor moment and peak hip abductor moment. In the sagittal plane, the peak knee flexor moment and the peak hip extensor moment were significantly lower in the GJH group although the absolute difference was small.ConclusionsThe walking pattern was the same for children with GJH and for healthy children, as there were no differences in kinematics, but it was, however, performed with different kinetics. Children with GJH walked with lower ankle, knee and hip joint moments compared to children with NGJH. However, the clinical importance of these differences during normal gait is unknown. To obtain this knowledge, children with GJH must be followed longitudinally.Trial registrationThe study was approved by the Committee on Biomedical Research Ethics for Copenhagen and Frederiksberg, Denmark (jnr. KF01-2006-178).
