A major 2026 review in Neuroscience and Biobehavioral Reviews brings fresh clarity to why chronic pain persists for so many patients — and why purely tissue-focused or pharmacological approaches often fall short. The paper, “Neuroinflammation, metabolic dysfunction, and chronic stress converge on the insular cortex in chronic pain” by García-Cancela, Conde-Vázquez, Navarro-Ledesma, and Pruimboom, positions the insular cortex (IC) as the brain’s central hub for interoception — our sense of internal bodily states.
Insular cortex – Wikipedia
It synthesizes evidence that chronic pain is not merely ongoing nociceptive input or central sensitization. Instead, often it reflects a destabilized interoceptive system shaped by cumulative allostatic load. Three converging biological pathways — neuroinflammation/immune signaling, metabolic dysfunction (insulin/leptin resistance, etc.), and chronic stress-axis activation (HPA/SAM) — alter insular structure, connectivity, and function. Lifestyle and anthropogenic factors (ultra-processed diets, sedentary behavior, sleep disruption, social isolation, pollutants, smoking) activate these pathways.
The result? A paradoxical interoceptive profile: reduced objective accuracy in sensing internal signals coexisting with heightened subjective attention and diminished bodily trust. Pain becomes the most coherent, salient signal in an imprecise internal landscape. The authors frame chronic pain partly as a disorder of interoceptive integration and predictive processing, calling for multimodal, non-pharmacological strategies that restore precision and reduce allostatic burden.
Garcia-Cancela et. al.’s research strongly validates… and extends… the BioBE framework in my Biomechanics and Interoception: A Biobehavioral Approach CE series I teach on CEsoup.com.
From Theory to Clinical Action: StrongPosture® BioBe Protocols
The Biobehavioral (BioBe) approach integrates biomechanics + interoception + predictive processing/active inference. By treating posture and movement as a real-time, accessible interface for updating the brain’s internal models of somatic function – the body’s capability to perform safely and effectively- we’re addressing precisely the processes the 2026 review highlights as disrupted in chronic pain.
Their conclusion:
“Disruptions across these systems may progressively bias internal models of the body towards persistent threat and imbalance, reinforcing allostatic load and favouring pain persistence”
ALSO…
“Understanding chronic pain through this integrative lens may help bridge biological mechanisms with behavioural and lifestyle-related interventions, opening new avenues for prevention and more comprehensive therapeutic strategies.”
My Conclusion: This is precisely the practical tools for NMS pros I teach in BioBE 20 hour course series:
- Observing Postural Balance with the Interoceptive Posture Picture (IPP) protocol — Making subtle postural and motor control asymmetries objectively visible begins the process of making it actionable. The PostureZone® grid lets patients literally see what their interoceptive/proprioceptive systems may be missing or mis-weighting. This directly targets the accuracy gap described in the paper.

- Re-aligning proprioceptive and interoceptive input with motor control output to couple in real-time with StrongPosture® BAM (Balance–Alignment–Motion) training — Reprogram sensory mismatch with graded movement experiments that help patients reweight sensory information (tuning into non-noxious proprioceptive, vestibular, and interoceptive signals alongside pain), create “positive surprises” that challenge threat-based predictions, and build new, more accurate internal models through experiential learning rather than explanation alone.
- Reprogram active inference for more accurate predictive processing by updating predictions about bodily capability and safety, reducing hypervigilance, and fostering sustainable habits grounded in body awareness instead of fear-avoidance behaviors.
These methods align tightly with the review’s discussion of interoceptive predictive processing (IPP), prediction errors, salience attribution, and the migration of representation from posterior sensory to anterior affective/evaluative insular circuits as pain chronifies. By improving objective interoceptive accuracy and bodily trust through posture and movement, we help stabilize the salience system so pain no longer dominates as the default coherent signal.
Addressing the Converging Mechanisms in Daily Practice
The course doesn’t stop at neural mechanisms. My Whole Person Health perspective frames biopsychosocial (BPS) models to for NMS clinicians to bridge interprofessional gaps with behavioral and other health care providers. BioBE integrates biomechanical and BPS models to equip clinicians to assess common individual lifestyle and biomechanical contributors that feed neuroinflammation, metabolic stress, and allostatic load (sedentary patterns, poor alignment increasing tissue stress, sleep disruption amplified by pain, etc.).
BAM protocols inherently promote the very behaviors the authors recommend: physical activity that supports metabolic health and stress regulation, mindful movement that can improve sleep quality and reduce sympathetic overdrive, and enhanced body awareness that supports better self-regulation and adherence to anti-inflammatory lifestyle choices (diet quality, circadian alignment, social connection).
Manual and touch-based elements common in chiropractic and manual therapy practice are also supported by the review’s discussion of their potential immunomodulatory and neuroendocrine effects. The BioBe framework helps you integrate these with targeted interoceptive training for greater impact.
Why This Matters for Your Patients — and Your Practice
Patients with chronic pain often feel their bodies are unreliable or unsafe. The course gives you concrete ways to demonstrate modifiability, restore a sense of agency, and shift from passive “fix me” expectations to active self-regulation. This is especially relevant for the growing number of patients whose pain involves nociplastic or primary pain features, where central and systemic factors predominate.
For healthcare professionals in neuromusculoskeletal care (chiropractors, PTs, osteopaths, massage therapists, and CPEPs), the series provides evidence-informed, immediately usable tools that complement — and in many cases outperform — traditional tissue-focused interventions alone. It also positions your practice at the intersection of contemporary pain science, active inference, and practical biomechanics.

The 2026 review makes a compelling scientific case. The BioBe approach — grounded in StrongPosture® BAM, IPP, and active inference principles — turns that case into repeatable clinical actions that improve interoceptive precision, update maladaptive predictions, reduce allostatic load, and help patients stand taller and live better.
If you’re already using grids, BAM exercises, or IPP in practice, the course will deepen and systematize your approach with the latest supporting neuroscience. If these ideas are new to you, it offers a clear, step-by-step pathway to bring them into your patient care.
