Chronic widespread pain and neurophysiological symptoms in joint hypermobility syndrome (JHS)
Bibliographic record
Abstract
Background Joint Hypermobility Syndrome (JHS) is a multisystemic connective tissue disorder characterised by pain, tissue fragility and laxity. This study aims to investigate the prevalence of chronic widespread pain (CWP) and the extended neurophysiological features reported by a group of patients with JHS. Methods Ninety patients with JHS (mean age 34.7 ± 9.9 years), which was diagnosed in accordance with the Brighton criteria, and 113 healthy volunteers (mean age 35.7 ± 12.9) with no musculoskeletal pain participated in the study. A self-report questionnaire and pain chart were employed to collect data. Results CWP was reported by 86% of patients with JHS. The mean number of pain sites in this group was 9.8/17 ± 4.2. Fibromyalgia was reported by 19% of this group. Patients with JHS were significantly more likely to report the following than healthy volunteers: autonomic symptoms (70%, 12%); gastrointestinal symptoms (71%, 9%); and chronic fatigue syndrome (31%, 1%). Patients with JHS reported significantly higher mean functional difficulties scores (22.28 ± 4.90) than healthy volunteers (17.96 ± 3.73) (P<0.001), indicative of functional difficulties associated with developmental coordination disorder/dyspraxia. Conclusion Patients with JHS reported a wide range of neurophysiological symptoms of which CWP was a salient feature. There is a need to acknowledge and understand the extended symptoms associated with CWP in order to address the holistic needs of patients with JHS. Further studies and discussion are required to identify the complex inter-related multifactorial neurophysiological mechanisms in those with JHS.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
