What's really behind an injury isn't just the tissue that's hurt.

I learned that twenty-five years ago, when I was starting out as an athletic trainer. My boss at the time and mentor, Marijeanne Liederbach, taught me to look at every injury through what's called a biopsychosocial lens — the idea that a person's biology, psychology, and social circumstances all shape how an injury happens and how it heals.


It was the first time I'd heard the concept named outright, and it changed how I approached injury prevention and rehabilitation from that point forward. An ankle sprain wasn't just an ankle sprain. It was an ankle sprain happening to a specific person, with a specific stress load, sleep pattern, support system, and history.


Years later, as I expanded into acupuncture, I was drawn to its theory without immediately realizing what I was looking at: a different medical tradition — Eastern rather than Western — built on essentially the same premise. At the core of both models is the same idea.


Everything in a person's life — environment, mental and emotional state, social relationships, physical and biological factors — shapes their health. And addressing any real dysfunction or disease means addressing the whole person, not just the site where the symptom shows up.


The Western version of this idea has a name and a birthdate: physician George Engel proposed the biopsychosocial model in the 1970s, describing health and illness as sitting at the intersection of three domains:


  • Biological (age, genetics, tissue health, physiologic reactions)

  • Psychological (mental and emotional health, beliefs, expectations)

  • Social (relationships, support systems, socioeconomic circumstances)


A symptom isn't caused by one of these in isolation. It emerges from how all three interact in a specific person, at a specific time.

An older model, saying something similar

Acupuncture theory got there first, just in a different vocabulary. Traditional Chinese medicine doesn't ask "what is causing this symptom" in a linear sense — it asks how a pattern of imbalance is showing up across the whole person.


The five-phase model (Wood, Fire, Earth, Metal, Water) maps physical organ systems to emotional states, seasons, tissues, and environmental factors, all in relationship to one another, generating and restraining each other in a constant loop. Anger and the Liver. Overthinking and the Spleen. Grief and the Lung. The body, mind, and environment were never treated as separate systems.


The terms are different. The underlying logic isn't. Both frameworks reject the idea that a symptom can be fully understood — or fully treated — by looking at tissue alone. Both treat balance, not the elimination of a single cause, as the marker of health. And both use the presenting complaint as one thread in a larger pattern, not the whole story.


What this means for pain, specifically

Current pain science backs this up in a way that used to be considered fringe. Chronic pain, in particular, is now understood to involve real changes in how the nervous system processes and amplifies signals — a phenomenon often called 'central sensitization'.


Stress, sleep, mood, and environment don't just "make pain feel worse." They change how the nervous system generates the experience of pain in the first place. Treating the injury site alone, without addressing the nervous system's role or the psychological and lifestyle load a person is carrying, leaves a major piece of the mechanism untouched.


This is where a biopsychosocial-informed approach to acupuncture does something most single-lever treatments can't.


A treatment plan built this way is addressing:

  • The local injury or tissue restriction - needling directly into affected muscle, fascia, and trigger points to restore glide, reduce adhesion, and support tissue healing

  • The nervous system - shifting the balance between sympathetic (fight-or-flight) and parasympathetic (rest-and-repair) activity, which changes how pain signals are processed centrally, not just where they originate

  • The psychological and lifestyle context - sleep quality, stress load, digestion, and emotional state, all of which are known to influence pain perception and healing capacity.


None of these three levers works as well on its own. All together, they reflect how pain actually behaves.

Why acupuncture is well suited to this moment in pain science

Acupuncture was never designed to isolate a single cause. It was built around reading a pattern across the whole person and intervening at multiple points in that pattern simultaneously — physical, neurological, and otherwise. That's precisely the model pain science is now converging on for chronic pain in particular, where tissue-only treatment so often plateaus.


For acute pain, addressing the local injury still matters most, and acupuncture does that directly by reducing inflammation, releasing trigger points, and supporting tissue repair. But as pain becomes chronic, the picture widens. The nervous system, the stress response, sleep, and mood all move from background factors to active drivers. A treatment approach that was already built to treat the whole pattern, rather than isolate one variable, has a natural advantage here.


Two medical traditions, developed a world and a few thousand years apart, arrived at a similar conclusion: health and pain are never just physical. Treating them as if they were is what tends to leave patients stuck.


→ If chronic pain hasn't responded to treatment that only addresses the injury site, that may be exactly why.
