Before and After the Accident: How Comparing Spine Examinations Helps Explain New Limitations

A car crash does not create a perfectly preserved “before” picture of the patient’s spine.

Most people have never had their lumbar range of motion measured. They have never undergone formal muscle-strength testing. Many may never have needed an MRI. Their medical chart may contain nothing more specific than an old note about occasional back stiffness.

Then an accident happens.

Suddenly, the same person cannot sit through a workday, lift groceries without pain, sleep comfortably, or drive across El Paso without stopping because pain travels into a leg.

For the injured patient, the change may feel obvious.

For the treating clinician—and particularly when a personal injury claim is involved—the challenge is translating that change into a medically defensible timeline.

Comparing pre-accident and post-accident information can be extremely valuable. But meaningful comparison involves far more than putting two MRI scans side by side. A careful evaluation considers historical imaging when it exists, previous symptoms, prior neurological findings, range-of-motion measurements, work abilities, everyday function, the mechanism of trauma, new objective examination findings, and how those findings evolve during recovery.

The central question is simple:

What changed after the accident?

You can often answer that question even without a detailed pre-accident spine examination.

A Hypothetical Patient: Daniel’s Lumbar Spine Before the Collision

Consider Daniel, a fictional 43-year-old El Paso warehouse supervisor.

Before his accident, Daniel occasionally noticed low-back stiffness after long shifts. He mentioned it once during a primary-care visit several years earlier but never had a lumbar MRI. No clinician had measured his lumbar flexion with an inclinometer. There were no documented reflex abnormalities, strength deficits, sensory changes, or radiating leg symptoms.

More importantly, Daniel was functioning.

He worked full duty.

He routinely walked across a large warehouse, climbed stairs, drove to work, lifted moderate loads, maintained his home, slept normally, and played recreational basketball with his teenage son.

No pre-accident MRI declares his spine “normal.”

There does not need to be.

His functional history forms part of his medical baseline.

That distinction becomes important because degenerative spinal findings are remarkably common in people without symptoms. A systematic review of 3,110 asymptomatic individuals found increasing rates of disc degeneration, bulging, protrusion, and other findings with age. For example, disc degeneration was reported in 37% of asymptomatic 20-year-olds and became progressively more common with age (Brinjikji et al., 2015).

Therefore, discovering degeneration on Daniel’s post-accident MRI would not automatically prove that his current pain, neurological symptoms, or functional restrictions existed before the collision.

The clinic discusses this distinction in greater detail in its guide to reconstructing a patient’s pre-accident medical baseline. Pre-Accident Medical Baseline Reconstruction

Visit One: Establishing the Post-Accident Starting Point

Daniel is rear-ended while stopped in traffic.

During the collision, his torso is restrained while rapid acceleration and deceleration transmit forces through his trunk and spine. He does not lose consciousness and is able to leave the scene, but over the next several hours his low back becomes increasingly painful and stiff.

When he presents for evaluation, the clinician does not assume the crash caused every symptom.

The examination begins by documenting the timeline.

Questions include:

• What happened during the collision?
• Where did the body move?
• When did the pain begin?
• Did leg pain, numbness, tingling, or weakness develop?
• Were similar symptoms present before the accident?
• What could the patient do before that he cannot comfortably do now?
• Were there previous accidents, back injuries, surgeries, or episodes of sciatica?
• Are there warning signs suggesting fracture, cauda equina syndrome, infection, or another urgent condition?

This history creates the first layer of the causation analysis.

Measuring What Can Be Measured

Daniel’s examination then looks for findings that can be documented and compared later.

These may include:

• Lumbar flexion, extension, rotation, and side bending
• Gait and posture
• Muscle strength
• Deep-tendon reflexes
• Sensory examination
• Straight-leg-raise or other nerve-tension testing
• Orthopedic testing
• Palpation and muscular guarding
• Functional movements such as sitting, standing, bending, or transitioning from a chair

Range-of-motion testing can help quantify movement loss, particularly when consistent measurement methods are used. However, restricted motion is not a fingerprint unique to trauma. Pain, guarding, degeneration, fear of movement, neurological disease, and other conditions can also reduce motion.

For that reason, range of motion supports the clinical picture but does not independently prove accident causation.

The same principle applies to neurological testing. Muscle weakness, altered sensation, diminished reflexes, or nerve-tension findings can provide important objective evidence of neurological involvement, but the clinician must still determine whether the findings are new, longstanding, worsening, improving, or attributable to another condition.

Dr. Jimenez’s clinical resource on lumbar radiculopathy discusses the importance of strength, sensation, reflexes, gait, and related neurological examination findings when nerve-root involvement is suspected. Lumbar Radiculopathy and Neurological Examination

Why Daniel Does Not Automatically Receive an MRI on Day One

Patients sometimes assume that a serious collision should automatically result in an MRI.

Current imaging guidance is more selective.

For uncomplicated acute low-back pain without red flags, routine early imaging is generally not recommended because many patients improve with conservative management, and imaging commonly identifies abnormalities unrelated to the patient’s symptoms. When significant trauma, progressive neurological findings, suspected fracture, cauda equina syndrome, or other clinical concerns are present, imaging decisions change accordingly (American College of Radiology, 2021).

This protects the patient from unnecessary testing while preserving access to advanced imaging when the clinical picture warrants it.

The clinic’s educational material similarly emphasizes matching X-ray, CT, or MRI selection to the suspected injury and clinical findings rather than treating imaging as an automatic step after every collision. Spine Trauma Imaging and Diagnostic Evaluation

Visit Two: Six Weeks Later, the Clinical Picture Has Changed

Daniel returns approximately six weeks later.

Some of the generalized muscular soreness has improved. However, his lumbar symptoms have not followed the same course.

He now describes pain extending from the lower back into one leg, intermittent tingling in his foot, and difficulty remaining seated for long periods.

He is still avoiding heavier lifting at work.

The new information matters.

His clinician repeats relevant portions of the examination rather than simply carrying forward the original findings.

Perhaps lumbar motion remains substantially restricted. Straight-leg raising reproduces familiar leg symptoms. The sensory exam identifies a reproducible difference in part of the affected leg. Strength, reflexes, and gait are carefully reassessed.

Now the chart contains something much more useful than two pain scores.

It contains a trajectory.

At the first visit, Daniel had primarily localized back pain and guarding.

By the second visit, persistent symptoms had developed a neurological pattern.

That progression may change the diagnostic question and justify additional evaluation.

When MRI Becomes More Informative

MRI is particularly useful for evaluating discs, nerve-related structures, the spinal canal, and many soft tissues.

If Daniel’s symptoms remain persistent or progressive and his examination suggests lumbar nerve-root involvement, a lumbar MRI may help determine whether a disc protrusion, stenosis, or another structural finding corresponds with the clinical pattern.

ACR criteria identify lumbar MRI without contrast as usually appropriate in selected patients with persistent or progressive symptoms who may be candidates for further intervention after appropriate conservative management.

The key phrase is clinical correlation.

An MRI is evidence.

However, the MRI does not provide a complete causation analysis.

What Happens If the MRI Shows Degeneration?

Suppose Daniel’s MRI identifies degenerative disc changes and an L4-L5 disc protrusion near a nerve root.

An insurer might focus on one word:

Degenerative.

But medically, the interpretation requires more nuance.

Degenerative findings commonly occur in people who have no back pain whatsoever. Brinjikji and colleagues found substantial rates of disc degeneration, bulging, protrusion, annular fissures, and other findings among asymptomatic individuals (Brinjikji et al., 2015).

That means an MRI should not be interpreted in either extreme.

A clinician should not automatically say:

“The degeneration proves the accident had nothing to do with the symptoms.”

Nor should the clinician say:

“Everything visible on this MRI was caused by the accident.”

Both statements may exceed what the evidence can establish.

A more defensible question is:

Does the imaging finding fit the patient’s post-accident symptoms, examination findings, neurological distribution, mechanism of injury, prior history, and clinical progression?

The clinic’s current causation guidance makes precisely this distinction: prior degeneration may be relevant, but it does not automatically explain new neurological findings or post-accident functional losses. Understanding Causation in Chiropractic and Injury Care

What If Daniel Actually Has an Old MRI?

Now imagine a better-than-reconstructed baseline exists.

Daniel underwent an MRI five years earlier after briefly straining his back while moving furniture.

That imaging can be extremely valuable.

A qualified clinician or radiologist may compare:

• Previously documented disc degeneration
• Disc contour and location
• Herniation or protrusion findings
• Canal or foraminal narrowing
• Vertebral changes
• Previous nerve-root involvement
• Other structural abnormalities

But even side-by-side imaging has limitations.

Different scanners, imaging sequences, patient positioning, slice thickness, technical quality, interpretation, and the time between examinations can influence what appears on a study. Imaging also does not directly measure pain.

Most importantly, a preexisting structural abnormality can remain anatomically similar while its clinical consequences change.

For example, an old MRI may show an L4-L5 bulge in a patient who previously had no leg symptoms, normal strength, unrestricted work capacity, and no treatment requirements.

After a collision, that patient may develop radiating leg pain, altered sensation, reduced lifting tolerance, and examination findings consistent with nerve irritation.

The causation question is therefore not limited to:

“Was this disc abnormality already there?”

It may instead become:

“Did the traumatic event materially aggravate a previously stable or asymptomatic condition?”

That is a different medical question.

When There Is No Pre-Accident MRI—and Usually There Isn’t

Most personal injury patients do not arrive with a complete pre-collision dataset.

Acknowledge that absence rather than fill it with assumptions.

Clinicians can often reconstruct a reasonable baseline from multiple sources:

• Primary-care records
• Previous chiropractic or rehabilitation records
• Earlier emergency department visits
• Prescription history
• Prior imaging when available
• Previous work restrictions
• Employment duties
• Sports and exercise participation
• Activities of daily living
• Previous complaints of back or leg pain
• Prior neurological symptoms
• Earlier accidents or injuries
• The patient’s own consistent history

No single piece establishes the entire baseline.

Together, however, they may answer the practical question of what the patient could do before the collision.

A person who worked unrestricted construction for years before an accident presents a different baseline than someone who was already unable to work because of chronic lumbar radiculopathy.

Thorough medical documentation should preserve that distinction, not erase it.

Visit Three: Recovery Becomes Another Source of Evidence

Daniel returns for another comprehensive re-examination several weeks later.

His lumbar motion has improved. Walking is easier.

He is sleeping longer.

His leg symptoms occur less frequently, and he can sit for longer periods before discomfort develops.

He is not fully recovered, however.

Heavy lifting still reproduces low-back and leg symptoms.

This third examination provides additional information.

Progress examinations allow clinicians to compare:

Visit 1: acute post-traumatic symptoms and measurable movement restriction.

Visit 2: persistent symptoms with new or clarified neurological findings.

Visit 3: partial recovery, measurable functional improvement, and identifiable residual limitations.

That timeline can be more persuasive medically than a chart that simply repeats “back pain 7/10” at every appointment.

The clinic’s documentation guidance recommends following measurable factors such as range of motion, neurological status, sleep, walking or sitting tolerance, lifting capacity, work ability, and activities of daily living across successive re-examinations. Defensible Medical Injury Documentation Best Practices

Functional Baselines Matter Because Injury Is More Than an MRI Finding

For patients, one of the most important concepts is also one of the simplest:

Function matters.

Before the collision, could you:

• Work an eight-hour shift?
• Drive without needing frequent breaks?
• Lift your child?
• Exercise?
• Sleep through the night?
• Bend to put on shoes?
• Carry groceries?
• Sit through a meeting?
• Walk several blocks?
• Perform household maintenance?

What can you do now?

A person’s inability to perform an activity does not, by itself, identify the injured tissue. But when functional loss develops immediately after a plausible traumatic mechanism and corresponds with examination findings, neurological changes, imaging, and subsequent clinical progression, it becomes an important component of the overall analysis.

This is why personal injury documentation should capture both anatomy and lived function.

Clinical Causation Is Built From Converging Evidence

A medically supportable causation opinion rarely rests on a single finding.

It becomes stronger when several independent pieces of evidence point in the same direction:

Mechanism: Were the forces capable of loading the involved tissues?

Temporality: Did symptoms begin or materially worsen after the event?

Baseline: What symptoms and limitations existed beforehand?

Objective examination: Are there reproducible orthopedic, neurological, movement, or functional findings?

Imaging: Do clinically indicated studies identify abnormalities that fit the presentation?

Anatomic correlation: Does the location of a structural finding reasonably correspond with the neurological or mechanical pattern?

Alternative explanations: Are degeneration, previous injuries, systemic disease, subsequent accidents, or other factors more persuasive explanations?

Clinical course: Does the patient’s evolution over time make sense for the working diagnosis?

No individual MRI, range-of-motion measurement, orthopedic test, or pain score automatically establishes causation.

What matters is consistency across the entire record.

That distinction matters, especially for attorneys. A healthcare professional can address medical causation and explain whether trauma is medically consistent with a new injury or aggravation. Ultimate legal questions concerning proximate cause, damages, and liability remain matters for counsel and the fact-finder.

Conservative Recovery Should Serve the Patient First

Careful documentation is not merely to create evidence.

It is to guide appropriate treatment.

When serious pathology has been excluded, and conservative care is appropriate, management may incorporate chiropractic care, carefully selected manual or soft-tissue approaches, progressive rehabilitation, mobility work, therapeutic exercise, and other non-invasive modalities based on the patient’s diagnosis and tolerance.

Exercise and movement-based rehabilitation have an established role in many low-back-pain presentations, although treatment should be individualized rather than applying one protocol to every patient (George et al., 2021).

For appropriate patients, an integrated clinic may also consider acupuncture, electroacupuncture, and other supportive modalities as part of a broader plan.

The goal is not simply to lower a pain score.

Meaningful gains include improved mobility, better sleep, greater confidence in movement, increased walking and sitting tolerance, return to work or family activities, and recovery of as much normal function as medically possible.

This reflects beneficence: treatment should serve the patient’s recovery.

It also reflects non-maleficence. When clinically appropriate, conservative and non-invasive strategies may allow recovery without immediately escalating to higher-risk procedures or unnecessary medication exposure.

And it supports autonomy. Patients should understand what their examinations show, what uncertainties remain, why testing is—or is not—being ordered, and what treatment alternatives are available so that they can make informed decisions alongside their existing healthcare team.

What Makes Dr. Jimenez’s Integrated El Paso Clinic Different?

Injury Medical Clinic PA, also known as Dr. Jimenez’s Injury Medical Chiropractic and Functional Medicine Clinic, uses a multidisciplinary structure designed to address both the mechanical and medical dimensions of injury recovery.

Dr. Alex Jimenez, DC, APRN, FNP-BC, CFMP, IFMCP, is dual-licensed as a Doctor of Chiropractic and board-certified Family Nurse Practitioner/Advanced Practice Registered Nurse. His work includes musculoskeletal and soft-tissue injury assessment, neurological screening, diagnostic coordination, chiropractic physical medicine, rehabilitation, and broader medical evaluation within his licensed scope.

Dr. Maria Guadalupe Cardenas, MD, a board-certified internal medicine physician with more than 40 years of clinical experience, serves as medical director and collaborative physician. The clinic lists Texas License #J2933 and NPI #1164426748 for Dr. Cardenas, and Texas APRN/FNP License #1191402 and NPI #1205907805 for Dr. Jimenez.

According to the clinic’s published materials, Injury Medical Clinic PA describes itself as the only El Paso practice combining this board-certified medical-director oversight with Dr. Jimenez’s dual DC/APRN-FNP soft-tissue injury role within its integrated personal-injury model.

For an injured patient, the practical benefit is coordination. A connected clinical framework can consider structural examination, neurological screening, medical risk assessment, imaging decisions, conservative treatment, rehabilitation, and referral decisions as one system rather than unrelated pieces of care.

The Most Important Comparison May Not Be Two MRIs

Daniel’s case shows why “before and after” should mean more than radiology.

There may be no pre-accident MRI.

There may be no old range-of-motion measurement.

Mild degeneration may have existed for years.

None of those facts automatically answers the causation question.

A careful clinician instead reconstructs the best available baseline, documents the post-traumatic presentation, performs repeat examinations when appropriate, investigates evolving neurological findings, orders imaging for a clinical reason, considers alternative explanations, and follows the patient’s recovery over time.

The resulting medical story may look like this:

Before: occasional stiffness, no radicular symptoms, full-duty employment, and normal everyday activity.

Immediately after trauma: new lumbar pain, guarding, movement loss, and reduced function.

Six weeks later: persistent limitations with a developing neurological pattern.

After further evaluation and care: objective and functional improvement, with clearly identified residual limitations.

That is a far more complete picture than saying, “The MRI shows a disc problem.”

For patients, it explains why repeated examinations matter.

For attorneys, it creates a chronological record in which medical reasoning can be examined rather than merely asserted.

And for clinicians, it keeps the most important priority where it belongs: determining what changed, why it changed, and what can safely help the patient recover.
