How I think about clinical care
Physical therapy and functional medicine aren't two separate disciplines bolted together. When applied well, they address different layers of the same problem — and together they explain what neither can fully explain alone.
Standard physical therapy is exceptional at what it was designed to do. It identifies structural and mechanical impairments, restores joint mechanics, rehabilitates tissue, and prescribes movement. In the right clinical context, that is exactly the right framework.
But most outpatient PT caseloads are not filled with clean mechanical problems. They are filled with chronic pain, recurrent injuries, tissue that won't heal on a reasonable timeline, and patients whose presentations don't map neatly onto a structural diagnosis. For that population — which is most of the patients I've seen over twenty years — the mechanical framework alone leaves too many questions unanswered.
Functional medicine asks the questions the mechanical framework can't. Why is this tissue not healing? What is the inflammatory environment this patient is living in? What systemic variables are determining whether any of this treatment is actually working?
"The structural examination tells me what is impaired. The functional medicine lens tells me why the body hasn't fixed it yet. I need both questions to give patients the best chance of actually getting better."
This page explains how I integrate these two frameworks in practice — the clinical logic behind it, the systems I evaluate, and the evidence standards I hold myself to. If you're a physical therapist considering this approach, or a patient trying to understand what makes this different, this is the place to start.
The clinical process
Four layers of evaluation, applied in sequence. Each one builds on the last and informs the treatment approach.
Every evaluation begins where physical therapy is strongest: identifying the structural impairment, assessing movement quality, understanding the mechanical contributors to the presentation. This foundation is non-negotiable. Functional medicine doesn't replace it — it builds on top of it. A thorough orthopaedic examination, movement screen, and functional assessment come first, every time.
Before the first treatment session, I want to understand the environment the tissue is trying to heal in. This means a broader intake than standard PT: diet quality and patterns, sleep architecture and consistency, stress load and recovery habits, gut health indicators, supplement use, and relevant health history that standard PT intake forms don't typically capture. These aren't lifestyle questions — they are clinical variables that directly affect tissue repair, pain perception, and recovery capacity.
Physical therapists don't order labs. But we work with patients who have labs, and understanding what those values mean — and what they tell us about the healing environment — is clinically valuable. I look at hs-CRP as a marker of systemic inflammatory load, fasting insulin and HbA1c for metabolic health, vitamin D and ferritin for tissue repair capacity, and ApoB for cardiovascular risk context. When patients bring labs to clinic, I know how to use that information. And I know when to encourage them to ask their physician for tests they haven't had.
Treatment combines standard PT interventions — manual therapy, therapeutic exercise, neuromuscular re-education, load management — with specific recommendations addressing the upstream variables identified in steps 2 and 3. This might mean an anti-inflammatory nutrition conversation alongside a tendon loading protocol. It might mean referring a patient for a sleep evaluation when their recovery is stalling in ways that don't fit the structural timeline. It means the treatment plan reflects the whole patient, not just the joint.
The systems I evaluate
These are the systems most likely to be the limiting factor when a patient isn't responding to standard PT care.
The gut microbiome regulates immune function, inflammatory signaling, and the absorption of the nutrients tissue repair depends on. When intestinal integrity is compromised, systemic inflammation rises — and that inflammation doesn't stay in the GI tract. It elevates circulating cytokines that directly impair tissue healing and amplify pain sensitization.
Collagen synthesis requires vitamin C, glycine, proline, and zinc. If a patient isn't absorbing well, the raw materials for tendon and ligament repair are unavailable regardless of how well the loading program is designed.
Tissue healing requires parasympathetic dominance. The sympathetic state — chronically elevated cortisol, suppressed digestion, reduced peripheral blood flow — is catabolic and repair-inhibiting. Many patients with delayed healing are spending the majority of their time in sympathetic dominance due to work stress, poor sleep, or unresolved psychological load.
You can apply the correct treatment to a patient whose nervous system cannot mount a healing response. Identifying and addressing autonomic dysregulation isn't soft — it's prerequisite physiology.
Insulin resistance and chronic hyperglycemia create an inflammatory environment that impairs tissue repair at the cellular level. Advanced glycation end-products (AGEs) accumulate in collagen-rich tissues — tendons, ligaments, cartilage — reducing their mechanical properties and healing capacity. This is not a diabetic-only concern. Subclinical metabolic dysfunction is common and frequently undiagnosed.
A patient with unrecognized insulin resistance is operating with structurally compromised connective tissue and a pro-inflammatory metabolic environment. Understanding this changes the prognosis conversation and the treatment priorities.
Sleep is when tissue repair happens. Growth hormone — the primary driver of soft tissue regeneration — is released in slow-wave sleep. Cytokine resolution, protein synthesis, and neurological consolidation of motor learning all occur during sleep. A patient getting five fragmented hours a night is working against every physical therapy intervention delivered during the day.
Sleep deprivation also lowers pain thresholds directly — meaning a poorly sleeping patient will report more pain at the same tissue state than a well-sleeping one. This is not psychological; it is neuroscience.
Tissue repair is energetically expensive. Every adaptive response to physical therapy — muscle protein synthesis, collagen remodeling, neuroplastic change — requires ATP. If a patient's mitochondria are producing energy inefficiently due to poor diet, sedentary history, oxidative stress, or micronutrient deficiency, their capacity to respond to treatment is reduced at the most fundamental biological level.
Chronic fatigue that doesn't respond to deloading, slow strength gains despite consistent training, and poor exercise tolerance out of proportion to deconditioning level are all signals worth investigating through this lens.
Pain is an output of the nervous system, not a direct readout of tissue damage. The research on central sensitization, fear-avoidance behavior, and the role of psychological and social factors in chronic pain is no longer emerging — it is settled science. A patient whose pain is driven primarily by a sensitized central nervous system requires a different approach than one whose pain is driven by active tissue pathology.
Identifying central sensitization early prevents the mistake of escalating loading programs on a nervous system that needs calming first. It also guides referral decisions — some patients need a therapist before they need a PT exercise program.
A few things worth being clear about — both what this framework includes and what it doesn't claim to be.
This approach is
Being clear about the limits of this framework is part of practicing it responsibly.
This approach is not
In practice, here is what I am looking for beyond the standard PT intake when a new patient presents — particularly one with a chronic or complex presentation:
Extended intake — what I ask about
This intake adds time. It is worth it. The picture that emerges routinely explains clinical presentations that the structural examination alone cannot.
Functional medicine has a reputation problem in some clinical circles — and some of it is deserved. There is a corner of this space that moves far ahead of the evidence, sells supplements aggressively, and applies single-cause explanations to complex problems. I have no interest in that version of functional medicine.
The framework I use distinguishes between three tiers of evidence, and I try to be explicit about which tier I'm drawing from:
If I make a clinical claim on this site, I try to be explicit about which tier it falls into. That distinction matters — both for your clinical decision-making and for the integrity of how this approach is represented.
The methodology page is the map. The library is where it gets put into practice — protocols, lab guides, case studies, and clinical tools built around these principles.
