Super Contractures: The Invisible Aftermath of Spinal Injury

Dr. Lamb — Tue, 09 Jun 2026 17:13:17 +0000

When a spinal injury heals, most people assume the tissue returns to something close to its original state. Scar forms, the acute phase resolves, and the body moves on. For a significant number of whiplash patients, that is not what happens. The body’s repair response produces something structurally different from the tissue it replaced, and in some cases, that new tissue may create more problems than the original injury.

Dr. G. Blair Lamb describes this process through the concept of super contractures: dense, organized bands of neuromyofascial scar tissue proposed to form around injured spinal segments in the weeks and months following trauma. Understanding what these are, how they may form, and why standard imaging is not designed to detect them is central to the question of why so many whiplash patients do not recover.

The Evolutionary Injury Response

When the spine sustains significant trauma, the body initiates what Dr. Lamb describes as the evolutionary injury response. It is a survival mechanism. The body detects structural instability in the injured region and responds by rapidly forming dense, fibrous stabilizing tissue around the damaged vertebrae and soft tissue. The goal is to create an internal cast, to immobilize the injured segment and prevent further damage.

In an acute setting, this response is protective and appropriate. In the short term, stabilizing a damaged spinal segment through fibrous tissue formation helps prevent the kind of secondary injury that movement through an unstable region could cause.

The problem, in this model, emerges over time. As the stabilizing tissue matures, it may become progressively denser, more disorganized, and more contractile. What began as a protective internal cast is proposed to transition into a pathological structure: tissue that shrinks and tightens, holds spinal vertebrae out of their natural alignment, compresses surrounding nerve roots, and in its most advanced form wraps around the spinal cord itself, restricting the gliding motion the cord depends on during movement.

This is the super contracture: tissue formed to protect the spine that becomes, in this model, a mechanism of chronic injury.

Why Standard Imaging Cannot See It

Standard MRI, X-ray, and CT scanning are designed to detect structural abnormalities: fractures, disc herniations, obvious soft tissue masses, gross alignment changes. They are not designed to detect the subtle density changes, fascial contractures, and dynamic restriction patterns that would characterize neuromyofascial super contractures.

The result may be a diagnostic blind spot affecting a substantial number of patients. A whiplash patient undergoes standard imaging, receives a report showing no significant abnormality, and is told their spine is essentially normal. If super contractures are present and contributing to their symptoms, they are invisible to the tools being used to look.

Curatolo and colleagues (2011) addressed this in a review of tissue damage in whiplash-associated disorders. They concluded that lesions of various tissues have been documented in animal, cadaver, and patient studies, that most are undetected by imaging, and that lack of macroscopically identifiable tissue damage does not rule out the presence of painful lesions. The same review is careful about what remains unknown: it states that the proportion of whiplash patients in whom a persistent lesion is the major determinant of ongoing symptoms has not been established, and that psychosocial factors, stress reactions, and generalized hyperalgesia also predict outcomes. Both halves of that conclusion matter. A normal scan does not rule out structural injury, and structural injury is not the whole story for every patient.

This is not a failure of imaging technology for the purposes it was designed for. It is a mismatch between what the technology is built to detect and what may be producing the patient’s symptoms.

Spinal Cord Tethering: When the Cast Becomes a Cage

Normally, the spinal cord glides freely within the spinal canal as the body moves. This gliding motion is essential for normal neurological function. The proposal in this framework is that when dense neuromyofascial scarring accumulates around the cord, it restricts that glide and the cord becomes tethered.

A tethered spinal cord does not simply stay still. It transmits tension. Movement that would normally allow the cord to glide instead generates mechanical tension along its length, and that tension may not stay localized. A tethering point at the upper cervical spine could transmit upward tension into the brainstem and cranial nerves, or pull downward, generating unexplained weakness or heaviness in the legs. In this model, that mechanism may contribute to the persistent headaches, vestibular disruption, visual changes, fatigue, brain fog, and sensory disturbances that whiplash patients describe and that brain-centered assessment does not fully explain.

Research in analogous conditions including adhesive arachnoiditis, tethered cord syndromes, and post-surgical spinal adhesions has documented neurological symptoms including pain, sensory disturbances, weakness, balance dysfunction, and fatigue arising from restricted neural mobility rather than gross compression. The specific mechanism of post-whiplash fibrosis producing spinal cord tethering as described by Dr. Lamb is a clinical hypothesis that warrants dedicated investigation. The biological plausibility of neural tissue becoming mechanically sensitized by adhesions and altered mobility is well established in this broader literature.

This proposed mechanism offers one explanation for why whiplash symptoms sometimes worsen over time rather than improving. If repair tissue forms and matures over the following weeks, months, and years, tightening as it does so, the symptom picture could worsen well after the injury event. The patient deteriorates years after a collision, and the connection between the two is missed because no one is examining what the repair process left behind.

Elliott and colleagues (2011) followed 44 patients after whiplash injury and found that muscle fat infiltration in the cervical extensors increased over six months in the group with moderate to severe disability, while remaining unchanged in those who recovered. A larger prospective study by Smith, Elliott and colleagues (2020) confirmed the pattern at twelve months, with infiltration concentrated in the medial portions of the deep cervical extensors and significantly greater in patients with severe chronic symptoms.

One finding from the 2011 study deserves attention because it complicates a purely mechanical account: initial post-traumatic stress symptom severity mediated the relationship between pain intensity and muscle fat infiltration, while initial range of motion loss did not. Tissue change after whiplash appears to be real, measurable, and progressive in patients who do not recover, and it also appears to interact with the stress response to the injury. Any complete model of why some patients deteriorate has to account for both.

The Kinetic Energy Factor

Dr. Lamb has noted, as discussed in the physics of whiplash, that the forces involved in motor vehicle accidents are routinely underestimated by patients, clinicians, and insurers alike. Kinetic energy rises with the square of the change in speed, which means modest increases in impact speed involve substantially larger forces. Even residential speed impacts involve forces the human body was not designed to absorb without tissue effect.

Siegmund and colleagues (2000) tested human cervical motion segments under combined posterior shear, extension, and axial compression and measured strain in the facet capsular ligaments. Their results suggest that these ligaments may be injured under load levels that occur in rear-end impacts. This is a biomechanical parallel to the broader neuromyofascial argument: meaningful tissue injury may occur at force levels that leave little obvious trace.

The proposal in this framework is that the severity of the super contracture response relates to the force absorbed by the spine, with higher-force injuries producing more extensive scarring, greater contracture density, and more significant tethering. That may be one reason some patients involved in apparently minor accidents develop severe chronic pain while others recover, alongside the pre-existing condition of the spinal tissues and individual variation in how the repair process organizes.

The Diagnostic Gap and What Follows It

When a patient with persistent pain receives a normal MRI result, the clinical pathway often moves toward symptom management rather than further structural investigation. That is a reasonable response to the information available. The concern is what happens when a structural contributor is present but has not been identified by the tools used to look for it.

Persistent symptoms after whiplash are common. A substantial proportion of patients report ongoing symptoms months to years after the initial injury, and a smaller but significant group experience moderate to severe chronic pain and disability. For those patients, the question of whether anything remains unexamined is worth asking.

Chronic pain that is poorly explained and poorly relieved is a difficult clinical situation for patients and physicians alike, and it is one of the reasons accurate diagnosis matters. The NMF Science position is not that neuromyofascial assessment resolves that difficulty, or that it addresses any broader public health problem. It is narrower: that where a structural contributor is present and unidentified, finding it is worth the effort, and that the tools to look for it deserve development and study.

What This Means for Patients

Patients who have been told their imaging is normal following a whiplash injury, who continue to experience pain and neurological symptoms that do not respond to standard rehabilitation, and who have been offered only symptom management deserve a different question: what did the injury leave behind that standard imaging is not designed to see?

The super contracture model offers one mechanistically coherent answer. Protective tissue forms after injury. That tissue matures into a structure that may itself generate symptoms. Identifying it, mapping it, and addressing it directly is the approach this framework proposes, and whether that produces better outcomes than symptom management is a question that requires formal study.

The biological concepts underlying this model are supported by a growing body of peer-reviewed evidence. The specific terminology and the full causal chain as Dr. Lamb describes it remain investigational. That is not a reason to dismiss the framework. It is a reason to investigate it.

Why Plantar Fasciitis Keeps Coming Back: The Spine and Hip Connection

Dr. Lamb — Mon, 08 Jun 2026 22:30:50 +0000

Plantar fasciitis is one of the most commonly treated foot conditions and one of the most frustrating. Stretching, orthotics, corticosteroid injections, and rest produce temporary relief for many patients without producing lasting recovery. One possible reason in chronic cases is that treatment is being directed at the endpoint of the problem rather than at what is loading it.

Part of that picture is well established in the published literature. Part of it is a clinical hypothesis that has not been tested. This article separates the two, because the difference matters for what a patient should reasonably expect.

What the Evidence Establishes: The Calf

The link between calf tightness and heel pain is not a fringe position. It is reflected in how foot and ankle surgeons already operate.

A study quantifying the relationship found a strong statistically significant correlation between gastrocnemius tightness and the severity of heel pain in patients with plantar fasciitis. A current concepts review of plantar fasciopathy notes that gastrocnemius tightness has been associated with ankle dorsiflexion stiffness and plantar fascia injury, and that isolated proximal medial gastrocnemius release has been reported for cases that have not responded to other treatment. That is surgery on the calf to resolve pain in the heel.

A systematic review of factors associated with chronic plantar heel pain found evidence of an association with decreased ankle dorsiflexion, alongside body mass index in non-athletic populations, the presence of a calcaneal spur, increased age, decreased first metatarsophalangeal joint extension, and prolonged standing. Reduced ankle dorsiflexion is, functionally, a tight calf.

The mechanical logic is straightforward. A shortened calf acts as a pulley under constant load, transmitting tension through the Achilles tendon and concentrating force on the plantar fascia at its attachment on the heel bone. The fascia develops inflammation and microtearing at that attachment, producing the characteristic pain on first steps in the morning. Treat the fascia while the calf remains short and the force generator stays active.

This also explains why Achilles tendinopathy and plantar fasciitis frequently occur together. Both sit at the ends of the same tensioned structure. Finding one is a reason to examine the other.

Where the Hypothesis Begins: The Spine

If a tight calf loads the plantar fascia, the next question is what is tightening the calf. This is where the neuromyofascial framework makes a proposal that the published literature does not yet address.

The lower limb functions as a continuous mechanical chain. Nerve roots exiting the lumbar and sacral spine travel through the hip, thigh, calf, and into the foot. The hypothesis is that where those nerve roots are compressed or irritated, whether from disc pathology, fibrosis, or neuromyofascial scarring at the lumbar or sacral levels, the effects would travel the length of the chain.

Specifically, the proposal is that nerve root involvement at L5 or S1 creates motor neuropathy in the muscles those roots supply, particularly the calf. The gastrocnemius and soleus would respond with dystonia, a state of chronic involuntary tension. A dystonic calf would then produce exactly the mechanical picture the published research describes: sustained tension through the Achilles and abnormal load on the plantar fascia.

That upstream link has not been demonstrated. Searches of the indexed literature do not turn up studies establishing a lumbar or sacral contribution to plantar fasciitis. What exists is a documented calf-to-fascia relationship and an anatomically plausible but untested account of what may drive the calf dysfunction in some patients. Presenting it as anything more settled than that would misrepresent the evidence.

The Layers of a Complex Presentation

Simple presentations may involve only the calf and foot, and often respond to local rehabilitation directed at both.

Chronic and more complex presentations, in my clinical experience, tend to involve several regions at once. The injury map in these cases typically spans the lower lumbar spine or sacrum, the pelvic and hip musculature, the hamstrings, the calf, and the foot. Each region may contain areas of dystonia or fibrosis contributing to the tension loading the plantar fascia.

Hip musculature is frequently overlooked. The piriformis, gluteus medius, and related pelvic muscles, when chronically tight or scarred, alter lower limb alignment and loading mechanics through the whole leg. That altered loading would compound whatever is happening further up and further down the chain. This is a clinical observation rather than a documented mechanism.

When the Foot May Not Be the Right Place to Look

In a small number of cases, heel pain has persisted through exhaustive local treatment, thorough lumbar and sacral assessment, and hip rehabilitation. In some of those patients, neuromyofascial assessment has identified findings in the upper thoracic or cervical spine.

That may seem counterintuitive, since the cervical spine and the plantar fascia are anatomically distant. The reasoning behind investigating it is that the spinal cord runs continuously from the brainstem downward, and that dysfunction at the level of the cord itself can in principle generate motor abnormalities in limbs well removed from the site of involvement. Whether that mechanism operates in plantar fasciitis specifically is an open question, and the observation that these findings are sometimes present does not establish that they are causing the heel pain.

These are unusual presentations. Most plantar fasciitis does not warrant cervical spine investigation. In the genuinely treatment-resistant patient who has worked through every local and regional approach without result, widening the assessment is reasonable.

What Assessment Should Cover

A thorough neuromyofascial assessment of chronic plantar fasciitis maps potential contributing sites from the lumbar and sacral spine down through the hip, pelvis, hamstring, calf, and foot, with the aim of identifying which appear to be active contributors and how they may be loading the fascia.

Care is then directed at the sites the map identifies rather than applied as a generic protocol. Whether that approach produces better outcomes than standard care in a controlled comparison has not been tested, and that study would be worth running. What can be said is that the calf is a documented contributor, that ankle dorsiflexion is a recognized associated factor, and that assessment stopping at the fascia is assessment that stops early.

Plantar fasciitis that keeps coming back may not be a stubborn foot problem. It may be an incomplete investigation.

The Injury Cycle That Turns Muscle Into Fat

Dr. Lamb — Mon, 08 Jun 2026 20:44:38 +0000

Most people assume that when a muscle is injured, it either heals or it does not. What they rarely hear is that under certain conditions, injured muscle appears to change into something else.

Over three decades of spinal research and clinical work, I have studied what happens to the deep intrinsic muscles of the spine following injury, particularly after whiplash. Part of what follows is documented in the imaging literature. Part of it is a clinical model of how the process unfolds, which the research has not yet tested. The distinction matters, so I have marked it throughout.

What the Imaging Research Documents

The most solid ground here is the fat and water MRI work led by James Elliott and colleagues, which measures fat content within the deep cervical muscles directly.

In one prospective study, 36 patients were imaged within one week of whiplash injury, then at two weeks and three months. There was no difference in muscle fat infiltration 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 those patients with poor functional recovery, and that routine imaging protocols may need to be reconsidered.

A larger study of 97 patients presenting to an emergency department after a motor vehicle collision followed them to twelve months. Neck muscle fat infiltration measured at one week, together with a traumatic distress score, significantly predicted neck disability at twelve months. Patients who recovered had lower fat infiltration than those with mild or moderate to severe outcomes at every time point measured.

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 at twelve months.

So the phenomenon is real, it is measurable within weeks, it tracks strongly with who does badly, and it is concentrated in exactly the deep stabilizing muscles this discussion concerns.

What the Research Does Not Settle

Two findings complicate any simple causal story, and both come from the same body of work.

The authors of the 97-patient study state plainly that it is unclear whether higher fat infiltration represents a pre-existing phenotype or a result of the trauma. If some patients arrive at their collision with deep spinal muscle already in a more vulnerable state, then fat infiltration measured a week later may be partly a marker of who they were before the accident rather than a product of it.

The second is more interesting still. An earlier study following 44 patients found that initial post-traumatic stress symptom severity mediated the relationship between pain intensity and muscle fat infiltration at six months, while loss of cervical range of motion did not. A psychological factor sat in the middle of the chain between pain and tissue change.

Neither finding undermines the importance of the tissue change. Both mean that a purely mechanical account of how it arises is incomplete.

The Clinical Model

What follows is my working account of the sequence. It is consistent with the imaging findings but has not been tested as a causal chain, and should be read that way.

A whiplash event does not simply strain the neck. It may directly injure the deep intrinsic spinal muscles, the small stabilizing muscles running alongside and between vertebrae. Those muscles respond with spasm, which is normally protective. But because they sit in close proximity to nerve roots, discs, and bony structures, persistent spasm may begin compressing those structures.

My proposal is that this compression affects the dorsal rami, the nerve branches supplying the deep spinal muscles, and that reduced nerve signal disrupts normal motor function such that the muscle loses its ability to relax. The result would be dystonia: persistent involuntary shortening that does not resolve on its own.

Once established, the cycle would become self-reinforcing. Sustained spasm generates scarring within the muscle over subsequent weeks and months. Dense fibrous change begins to immobilize spinal segments, which compounds compression on discs and nerve roots and alters spinal mechanics further. Muscle deprived of normal signal and locked in a state it cannot escape progressively stops functioning as contractile tissue, and is replaced by fat. That endpoint is the part the imaging research measures directly.

The imaging confirms the destination. Whether the route I have described is how patients get there is a hypothesis that would require dedicated study, including electrophysiological assessment of the dorsal rami, to test properly.

Why Standard Rehabilitation Can Reach a Ceiling

Physiotherapy, exercise, and manual therapy are valuable for many spinal pain presentations. They work when the underlying tissue can respond to load, movement, and progressive strengthening.

Where tissue has been substantially replaced by fat and fibrous change, the picture is different. This is not a failure of rehabilitation as a discipline, and it is not an argument against trying it. It is a question about what the tissue being asked to respond is actually made of.

It is worth being honest about the limits of what is known here. I am not aware of studies establishing whether deep cervical fat infiltration is reversible, or whether any particular intervention reduces it. The research establishes that it predicts poor outcome. Whether changing it changes the outcome is a separate question, and one nobody has yet answered. That gap is a reason for research rather than a reason for confidence in any approach, including mine.

What This Means for Patients

Chronic spinal pain after an injury is often accompanied by confusion and frustration. Imaging comes back normal or near normal. Rehabilitation produces partial improvement that then plateaus. Symptoms persist despite reasonable effort.

Part of what may be missing is recognition that measurable structural change can occur in the deep spinal tissues within weeks of injury, that standard imaging protocols are not designed to detect it, and that it predicts who will still be symptomatic a year later. A patient whose routine MRI is unremarkable has not been shown to have normal deep cervical muscle. They have been shown to have an unremarkable routine MRI.

The neuromyofascial approach is to assess these tissues directly, stage what is found, and direct care accordingly rather than managing symptoms at the surface. Whether that produces better outcomes than existing rehabilitation in a controlled comparison has not been tested. The imaging research makes a strong case that something structural is happening early in the patients who do not recover, and that identifying it sooner would be worth doing.
