Behavioral Feedback Loops and Kinesiophobia in Hidradenitis Suppurativa: A Conceptual Framework

Introduction: Hidradenitis suppurativa (HS) is a severe inflammatory dermatosis characterized by debilitating localized pain. Current HS feedback models focus on microscopic molecular networks and bacterial dysbiosis. Objectives: This narrative review integrates the individually well-documented psychosocial and behavioral burdens of the disease into a single positive feedback model. Methods: A macroscopic behavioral framework was conceptualized by reviewing cross-disciplinary literature regarding HS. Results: This conceptual framework operates across three domains: i) a biomechanical-metabolic loop, where sustained immobility may accelerate the accumulation of visceral adiposity and insulin resistance; ii) a psychosocial loop, where symptom-induced psychiatric comorbidities may contribute to neuroendocrine dysregulation and compensatory coping behaviors; iii) a socioeconomic loop, where economic instability can decrease healthcare security and hinder effective disease management. Consequently, these interconnected burdens may result in increased systemic inflammation, which in turn exacerbates the pathophysiology of HS. Moreover, this review proposes kinesiophobia (the anticipatory fear of movement) as a hypothesized component of the biomechanical-metabolic feedback loop. Conclusion: Currently, there is a notable absence of primary psychometric data quantifying kinesiophobia in the HS population. Future research should aim to quantify this clinical construct in this demographic to establish its prevalence and clinical significance. On a systems level, clinicians could consider systematically addressing these broader behavioral feedback loops through multidisciplinary approaches that incorporate targeted interventions such as cognitive behavioral therapy and structured patient education. Ultimately, dismantling these behavioral cycles may be a critical step towards attenuating systemic inflammation, halting disease progression, improving therapeutic efficacy, and enhancing long-term clinical outcomes.
