Korean Spinal Manual Therapy Explained Chuna is at the heart of Korean therapeutic bodywork — and for most people outside Korea, it is entirely unfamiliar. That is about to change. Chuna (추나) is a Korean manual therapy system formalized as a clinical discipline in 1991 and covered under Korea's National Health Insurance since 2019. The name combines chu (推, to push) and na (拿, to grasp) — the two fundamental motions of manual intervention. A Synthesis of Four Traditions Modern Chuna systematically integrates: Traditional Korean medicine — constitutional diagnosis, meridian-b...

Part 7B: Kinesiophobia and Allodynia: When the Body Learns to Hurt · Korean Therapeutic Bodywork Korean Therapeutic Bodywork · A Modern Neuroscience Perspective 34-Part Series Series Home › Section 7: Fear, Avoidance, and Recovery › Part 7B Part 7B · Section 7: Fear, Avoidance, and Recovery Kinesiophobia and Allodynia: When the Body Learns to Hurt Kinesiophobia (fear of movement) and allodynia (pain from non-painful stimuli) are deeply connected — both reflect a nervous system trained by experience to be hypersensitive. Patients with kinesiophobia progressively restrict movement far below what their physical condition would warrant. Each avoided movement reinforces the belief that movement is dangerous. Allodynia — pain from light touch, temperature changes, clothing against skin — is the direct neurophysiological expression of this same loop. Allodynia: Not Imagined Pain Allodynia is real pain ari...

Part 7A: The Fear-Avoidance Model: Why Some People Don't Recover · Korean Therapeutic Bodywork Korean Therapeutic Bodywork · A Modern Neuroscience Perspective 34-Part Series Series Home › Section 7: Fear, Avoidance, and Recovery › Part 7A Part 7A · Section 7: Fear, Avoidance, and Recovery The Fear-Avoidance Model: Why Some People Don't Recover Two people sustain identical injuries. One recovers in six weeks. The other is still in pain two years later. The fear-avoidance model explains why. The fear-avoidance cycle is one of the most important clinical concepts in pain rehabilitation. It explains how acute pain becomes chronic — not through ongoing tissue damage, but through threat perception, avoidance behavior, and the deconditioning and sensitization that follow. The Fear-Avoidance Cycle Injury or painful episode occurs Pain is interpreted as highly threatening Fear of move...

Part 6B: The Neurophysiological Turn: How Manual Therapy Really Works · Korean Therapeutic Bodywork Korean Therapeutic Bodywork · A Modern Neuroscience Perspective 34-Part Series Series Home › Section 6: How Manual Therapy Works › Part 6B Part 6B · Section 6: How Manual Therapy Works The Neurophysiological Turn: How Manual Therapy Really Works If manual therapy does not work by correcting alignment, what does it do? The answer comes from three levels of the nervous system. Manual therapy works through peripheral, spinal, and supraspinal neurophysiological mechanisms — not structural correction. Each level contributes to the therapeutic effect, and they reinforce each other in a cascade that can outlast the treatment session by days. Three Levels of Effect Peripheral level: Mechanical stimulation of paraspinal sensory neurons changes the sensory input to the spinal cord. The direction, velocity, an...

Part 6A: Why the Structural Model Has Limits · Korean Therapeutic Bodywork Korean Therapeutic Bodywork · A Modern Neuroscience Perspective 34-Part Series Series Home › Section 6: How Manual Therapy Works › Part 6A Part 6A · Section 6: How Manual Therapy Works Why the Structural Model Has Limits The dominant twentieth-century explanation for what manual therapy does — correcting alignment, fixing subluxations — turns out to lack empirical support. What actually changes is the nervous system. The structural model — joints misaligned, vertebrae subluxated, the practitioner's job to put things back — dominated manual therapy for most of the twentieth century. Science has substantially complicated this picture. What the Research Found A 2024 systematic review examining whether spinal manipulation produces measurable anatomical structural changes concluded that the empirical evidence supporting struc...

Part 5C: Regulating Qi — Korean Medicine's Framework for What Neurochemistry Describes · Korean Therapeutic Bodywork Korean Therapeutic Bodywork · A Modern Neuroscience Perspective 34-Part Series Series Home › Section 5: Neurochemistry of Touch › Part 5C Part 5C · Section 5: Neurochemistry of Touch Regulating Qi: Korean Medicine's Framework for What Neurochemistry Describes Two vocabularies, one phenomenon — the convergence of neurochemistry and Korean medicine's concept of Qi regulation. The neurochemical effects of skilled manual touch — cortisol reduction, serotonin and dopamine increase, oxytocin-mediated spinal modulation, HRV improvement — describe what happens at the molecular level when the body shifts from a threat state to a regulatory state. Korean medicine describes this same shift in the language of Qi regulation (行氣). Two Languages, One Phenomenon Where there was sympathet...
