Your Body Isn’t Failing in Five Separate Ways

Dr. Lamb — Tue, 16 Jun 2026 18:40:23 +0000

When a patient describes waking up with a stiff neck, a migraine by noon, a numb hand by evening, and a familiar ache down the leg, the standard medical response routes each symptom through a different door. A neurologist for the head. An orthopedist for the hand. A pain specialist for the back. Each clinician assigns a label. Each label generates a treatment. And the patient returns home carrying five separate diagnoses, five separate explanations, and often, very little resolution.

I have spent more than thirty years examining that pattern, and I no longer believe those five symptoms are always separate problems.

The neuromyofascial science framework I developed is built around a different premise: that many of the most common and persistent pain presentations may be connected expressions of one underlying physical process. The symptoms look different because they surface in different parts of the body. The proposal is that the architecture producing them is often unified.

Understanding that architecture changes what you look for, and where.

What Is Acquired Neuromyofascial Pathology?

The central concept in this framework is what I refer to as acquired neuromyofascial pathology. This is not a single injury event. The proposal is that it is a cumulative process: over years and decades, microinjuries accumulate in predictable regions of the spine and limbs, scar tissue forms, and the density of the affected connective tissue increases. The working hypothesis is that this increased density begins to have mechanical consequences, including altered spinal positions, compressed joints, and irritation of the nerve roots passing through the region.

The process is slow, quiet, and difficult to see on standard imaging. Because the proposed damage lives in soft tissue density rather than in bone or disc, routine MRI and X-ray are poorly suited to detect it. Patients come in with real symptoms that do not correspond to findings on the scans used to look for them. The scan comes back clean, and the clinical response is often some variation of: this is just a normal part of getting older.

Fifty is still fifty. Sixty is still sixty. But the pain you are feeling is not always explained by age alone. In some cases, that pain may be the result of mechanical, structural burden that has been compounding for years.

Acquired neuromyofascial pathology, as proposed in this framework, involves site-specific increases in connective tissue density and scarring that develop over years or decades. Unlike bone fractures or disc herniations, this type of soft tissue change is not typically identified on routine MRI or X-ray. It requires physical examination and specialized assessment methods to locate.

Fascia Is Not Passive Wrapping

For a long time, the connective tissue scaffolding of the body, fascia, was treated as anatomically inert. It was considered wrapping. Background material. Anatomists dissected it away to reach the structures underneath.

That understanding has been substantially revised. Research reviewed by Gromakovskis (2025) supports the position that fascia is a richly innervated, biologically active tissue. It contains nociceptors, sympathetic fibers, and mechanoreceptors. When this tissue undergoes pathological change, including densification, fibrosis, and impaired sliding between tissue layers, it may not be a passive bystander to the pain process. That review describes fascia as a potential peripheral driver of myofascial pain, while noting that the current evidence remains preliminary and heterogeneous.

This matters clinically because it changes the target. If the connective tissue itself is pathological, treating only the downstream symptom may miss the source.

Measuring What Cannot Be Seen on MRI

One of the most useful recent developments in this area is the application of diagnostic ultrasound to connective tissue mechanics. Tomita and colleagues (2025) measured elevated thoracolumbar fascia shear strain in patients with nonspecific low back pain compared with asymptomatic individuals, in 32 patients and 32 controls. Those elevations correlated with pain and disability scores, while fascia thickness was comparable between groups.

The direction of that abnormality is still being worked out. Vining and colleagues (2023) describe shear strain between fascia layers as reduced in chronic low back pain rather than elevated. Two research groups, measuring the same tissue with similar technology, currently report opposite directions of change. That disagreement is worth stating plainly, because it tells you the field is early. What both groups agree on matters more than where they differ: the mechanical behaviour of fascia is measurably different in people with chronic back pain, and it can be quantified.

More recently, Tomita and colleagues (2026) ran a randomized trial testing whether those mechanics can be changed. Sixty participants received acupuncture, chiropractic care, or no treatment, with the untreated group later receiving massage. Chiropractic care reduced cumulated fascia shear strain by roughly 16 percent and massage by roughly 32 percent, while acupuncture produced no detectable change. In the untreated control period, shear strain increased. Only the chiropractic group showed improvement in disability scores.

One finding in that trial deserves emphasis because it cuts against a simple story: the change in fascia mechanics did not correlate with the change in disability. Manual therapy moved the tissue measurement and moved the clinical outcome, but not in lockstep. That is a caution against assuming that a mechanical measurement is the same thing as the patient’s experience, and it is precisely the kind of question that needs formal study rather than assumption.

What this body of work establishes is narrower than a vindication of any framework, and more useful. Fascial mechanics can be measured. They differ in people with chronic pain. They change in response to physical intervention, and they drift in the absence of it. The neuromyofascial framework proposes that those mechanics are a meaningful part of what produces chronic symptoms in some patients. The imaging work suggests that proposition is testable, which is the necessary first step toward knowing whether it is correct.

The Spine-to-Limb Chain

One of the clearest places to examine this connected architecture is carpal tunnel symptoms and hand numbness.

The intuitive assumption is that a numb hand is a wrist problem. That is where the symptoms are. That is where the standard diagnosis lands. But in the neuromyofascial framework, numbness and tingling in the hand may be downstream signals from a disruption further up the chain. The site of pathology may be in the neck, at the shoulder outlet, at the axilla, or at the elbow. The wrist may be a terminal expression of a restriction that originated above it.

The medical literature engages this logic through the concept of double crush syndrome, a recognized clinical framework in which concurrent cervical radiculopathy exists alongside a peripheral nerve entrapment such as carpal tunnel syndrome. The evidence on how best to treat it is still developing, and it is not one-sided. Hansen and colleagues (2024) found that patients with double crush syndrome improved after carpal tunnel release at rates comparable to patients with carpal tunnel syndrome alone, and concluded that carpal tunnel release is a reasonable first step before proceeding to cervical decompression.

Surgical sequencing data points in a different direction. Holloway and colleagues (2025) examined patients who underwent both cervical and peripheral nerve decompression and found that those who had cervical decompression first showed significantly better functional outcomes at one month, six months, and one year. Primary cervical decompression was associated with roughly 2.5 times the odds of achieving a clinically meaningful improvement in physical function. Patients who had both carpal and cubital tunnel release, rather than one alone, also did better. The authors concluded that cervical pathology may have a greater impact on overall outcomes and should be prioritized in surgical planning.

That is the clinical logic of the spine-to-limb chain: the proximal contribution appears to matter, and the sequence in which the pathway is addressed may affect the result. The same logic applies to presentations well beyond carpal tunnel.

Mapping the Architecture

If the standard examination and standard imaging are not designed to locate these injury sites, a different method is required.

A specialized neuromyofascial examination is a physical process. It relies on manual evaluation of the tissue itself, identifying regions of abnormal density, restricted sliding, and altered mechanics that do not produce findings on MRI. In more advanced cases, additional clinical confirmation can help establish the location and nature of the suspected pathology.

The objective of this process is not to assign a new diagnostic label. Labels are descriptions of symptoms. What the neuromyofascial audit produces is a map: where the tissue appears abnormal, how dense it is, and which nerves, joints, or spinal regions may be mechanically compromised as a result. That map informs the care pathway.

If findings are identified early, targeted self-care and tissue remodeling approaches may address the density before it compounds further. In more advanced cases, where decades of accumulation have produced significant structural burden, more intensive non-interventional or interventional approaches may be required. The map does not just identify what is present. It indicates how far the pattern has progressed, and what level of intervention the tissue may need.

Why This Matters for Patients Who Have Not Found Answers

The patients who spend years carrying multiple diagnoses, cycling through specialists, and completing treatment after treatment without sustained improvement are not failing to respond. In some cases, they may be being treated for the output while the input remains unaddressed.

Where a stiff neck, a migraine, a numb hand, morning stiffness, and sciatica trace back to a shared architecture of acquired soft tissue pathology, treating each symptom individually may be an incomplete strategy. The relief, when it comes, tends to be partial and temporary, because the compounding process continues if the source has not been found.

Neuromyofascial science is an attempt to answer a different question: not what label fits the symptom, but what physical site may be producing it. The embedded resources on this page, including a full explainer video and an annotated slide presentation, walk through the specific anatomy and clinical evidence in detail. The written summary above is the framework. The media is the mechanism.

When the MRI Says Normal But the Pain Says Otherwise

Dr. Lamb — Fri, 05 Jun 2026 19:02:41 +0000

One of the most frustrating experiences in medicine is a patient who has been in significant pain for months or years, has undergone every standard test, and keeps receiving the same answer: your imaging is normal.

The imaging is not lying. But it may not be telling the whole story.

For nearly three decades I have been interested in what standard imaging is not designed to detect: structural change in deep spinal muscle tissue after injury. There is now a measurable body of research on this, and it is worth understanding both what it establishes and where it stops.

What Standard Imaging Can and Cannot See

X-ray, CT, and MRI are excellent tools for identifying fractures, disc herniations, gross anatomical abnormalities, and tumours. They are not designed to quantify changes within the spinal muscles themselves, particularly in the weeks and months following a whiplash event.

It is common to see patients who have been in a motor vehicle accident, who develop chronic spinal pain, and whose imaging reports come back normal or near normal. That does not establish that nothing happened to their spine. It establishes that nothing appeared on a study not built to look for this.

There have been advances in soft tissue spinal MRI and in spinal ultrasound over the past two decades. They are meaningful, and they remain limited in routine clinical practice.

Fat and Water Imaging: What It Measures

Fat and water MRI measures the proportion of fat within a muscle directly, rather than inferring it from appearance. Applied to the deep cervical muscles after injury, it has produced some of the most useful data in this field.

I describe the underlying process as spinal marbling, by analogy with a heavily marbled cut of beef. Functional contractile muscle is progressively displaced by fat. That is a descriptive term of mine rather than a clinical one, but the phenomenon it describes is measurable.

In a prospective study, 36 patients were imaged within one week of whiplash injury, again at two weeks, and at three months. There was no difference between groups at enrolment. By two weeks, patients who would go on to report severe disability at three months already showed significantly higher fat infiltration in the cervical multifidus than those who recovered. A threshold of 20.5 percent fat infiltration at two weeks predicted poor outcome at three months with 87.5 percent sensitivity and 92.9 percent specificity. The authors concluded that muscle degeneration occurs soon after injury, but only in patients with poor functional recovery, and that routine imaging protocols may need to be reconsidered.

A larger cohort of 97 patients followed to twelve months found that neck muscle fat infiltration at one week, together with a traumatic distress score, significantly predicted neck disability at one year. A confirmatory study found the infiltration concentrated in the medial portions of the deep cervical extensors, with the magnitude significantly greater in patients with severe chronic symptoms.

An earlier study of 44 patients found something that complicates a purely mechanical reading: initial post-traumatic stress symptom severity mediated the relationship between pain intensity and fat infiltration at six months, while loss of range of motion did not. The authors of the 97-patient study were likewise explicit that it is unclear whether higher fat infiltration represents a pre-existing characteristic or a result of the trauma.

So the picture is genuinely interesting and genuinely unfinished. The tissue change is real, measurable within two weeks, and strongly predictive of who does badly. How it arises, and whether it is cause or consequence, is not settled.

The Lower Back: A More Cautious Picture

Similar work has been done in the lumbar spine, and the findings there are more mixed. They are worth reporting accurately rather than selectively.

Mengiardi and colleagues used proton MR spectroscopy to measure fat content in the lumbar multifidus and longissimus muscles of 25 patients with chronic low back pain and 25 asymptomatic volunteers matched for age, sex, and body mass index. Mean fat content in the multifidus was 23.6 percent in the pain group and 14.5 percent in the volunteers, a significant difference. In the longissimus, the difference was not significant.

Two further findings deserve attention. Using a semiquantitative grading scale, the differences between patients and volunteers were not significant, and nearly half the pain patients graded zero for multifidus fat, as did just over half the volunteers. And no significant correlation was found between fat content and pain intensity, pain duration, or self-rated disability.

That is a more restrained result than the cervical whiplash data. Fat content in the lumbar multifidus is elevated as a group difference in chronic low back pain, but it does not track with how much pain an individual patient has or how long they have had it. Anyone citing this work as evidence that fat infiltration explains low back pain is citing more than it says.

The Shoulder: Where Nerve and Tendon Can Be Distinguished

The rotator cuff is where the mechanism behind fatty infiltration has been studied most directly, and the findings are relevant well beyond the shoulder.

Fatty infiltration of the supraspinatus is measured routinely in shoulder practice. It correlates with tear size, it is an independent risk factor for retear after surgical repair, and its severity predicts treatment outcome. The conventional explanation is that the tear comes first, with tendon retraction and reduced loading driving the fatty change that follows.

That explanation is not the whole picture. A controlled laboratory study separated the two mechanisms directly. Twenty-two rabbits underwent bilateral shoulder procedures randomized to suprascapular nerve transection alone, tendon transection alone, both combined, or control. By six weeks all groups showed muscle atrophy along with increasing adipocytes and fibrosis on histology. Between six and twelve weeks, only the isolated nerve injury group showed a continuing increase in fatty infiltration. The authors concluded that tendon injury and nerve injury are each independently associated with increased fatty infiltration and muscle fibrosis.

The distribution differed as well. Tendon injury concentrated fat near the myotendinous junction. Nerve-mediated fatty infiltration was diffuse.

That distinction holds in humans. A comparative analysis by Beeler, Ek and Gerber examined 20 shoulders with chronic rotator cuff tears and no electromyographic evidence of suprascapular neuropathy, against 17 shoulders with documented suprascapular nerve dysfunction and no tear. Muscle changes following chronic cuff tear differed from those following denervation, particularly in the appearance of the muscle border, the degree of perineural fat, and the overall distribution of infiltration. The authors concluded that highly specific and characteristic morphological patterns exist for each.

Two things follow, and they matter for the wider argument here. Nerve injury alone is sufficient to produce fatty infiltration in skeletal muscle, with no tendon damage at all. And the fat resulting from nerve injury is distinguishable on imaging from the fat resulting from mechanical injury, meaning the two causes are separable rather than interchangeable.

Whether nerve involvement originating in the cervical spine contributes to fatty change in shoulder or spinal musculature in the way I propose has not been studied. What this research establishes is that the mechanism is real in principle: compromise the nerve supply to a muscle and fat accumulates within it, in a pattern distinguishable from other causes. That is a foundation for the question rather than an answer to it.

Why This Matters Clinically

Fat and water imaging is not new in research. It has been accumulating in the literature for two decades. What it has not done is translate into routine clinical practice, and most patients presenting with chronic spinal pain after whiplash are assessed with protocols not designed to detect this type of change.

The clinical implication in the cervical whiplash setting is reasonably strong. A measurement taken at two weeks predicted three-month outcome with high sensitivity and specificity in the study cited above. If that finding replicates in larger cohorts, early identification could change how care is sequenced and how closely patients are followed.

It is worth being honest about what remains unknown. I am not aware of studies establishing whether deep cervical fat infiltration is reversible, or whether any intervention reduces it, or whether reducing it changes outcomes. The research shows it predicts who does badly. Whether it is a target or a marker is a separate question that has not been answered.

Much of the NMF Science investigational framework is built around intrinsic spinal pathology as a contributor to chronic pain. This imaging research provides measurable evidence that deep spinal tissue undergoes structural change after injury that standard imaging does not capture and that predicts poor recovery, and the shoulder work establishes that nerve compromise alone can produce that kind of change. It does not confirm the wider framework, and I would not present it as doing so. It confirms that something structural is happening early in the patients who do not recover, and that nerve involvement is a plausible route to it. Those are narrower claims and better supported ones.

Further research is needed, and I expect it to refine both the diagnostic thresholds and the clinical applications of these findings.
