Linking central sensitization to multisystemic manifestations in hypermobile Ehlers-Danlos syndrome 2026 Zarazúa et al

Abstract

Hypermobile Ehlers-Danlos Syndrome (hEDS) and Hypermobility Spectrum Disorders (HSD) are complex multisystemic conditions frequently associated with chronic pain. Central Sensitization (CS)—a state of neural amplification and hyperexcitability—is hypothesized to be a unifying mechanism underlying the heterogeneous symptoms in chronic pain patients.

Our aim was to investigate the association between central sensitization and multisystemic symptom burden in patients with hEDS/HSD while identifying independent clinical predictors of CS. We prospectively enrolled 150 adults diagnosed with hEDS/HSD at a specialized joint hypermobility clinic. Participants were evaluated using the Central Sensitization Inventory (CSI) and the SPIDER questionnaire. Clinical CS was defined as a CSI score > 40. Statistical analyses included univariate correlations and multivariable logistic regression.

Centrally sensitized patients (n = 76) were significantly younger and predominantly female compared to the non-CS group. While CSI scores correlated strongly with all eight SPIDER domains (p < 0.001), a multivariable logistic regression model (AUC 0.98) identified only three independent predictors of CS: fatigue (OR 1.089), pain (OR 1.067), and cardiac dysautonomia (OR 1.057).

Central sensitization in hEDS/HSD is independently associated with a triad of fatigue, pain, and cardiac dysautonomia. Clinical management should shift toward multidisciplinary strategies to effectively address the sensitized state in this population.

This is hopeless. They will have recruited a very highly selected group of people who are attending a clinic because of unexplained pain anyway. They are almost certain to score high on a 'central sensitisation' questionnaire. A bias to young women almost certainly reflects further biases in recruitment and other things.

And Zodiac signs are associated with the precession of Earth and its current position around its axis. A questionnaire asking about symptoms finds associations between symptoms and a vague, generic circular concept. Super duper useful stuff.

What a word salad of misinformation.

Just picking out one:

Central Sensitization (CS)—a state of neural amplification and hyperexcitability—is hypothesized to be a unifying mechanism underlying the heterogeneous symptoms in chronic pain patient

CS is diagnosed by questionnaire that anyone with unexplained physical symptoms including pain will score highly on. It's not a biological explanation of anything. The whole thing is fantasy.
