For personal injury attorneys, one of the recurring challenges in a motor vehicle case is explaining why a client can continue to experience significant neck pain months after a collision—even when there was no fracture, hospitalization, or dramatic finding on the initial imaging.
A study published in the medical journal Injury provides an interesting perspective on both the chronic nature of whiplash-associated disorders and the potential role of chiropractic treatment.
Researchers Woodward, Cook, Gargan, and Bannister evaluated patients suffering from chronic symptoms following whiplash injuries. Their findings deserve attention from attorneys handling car crash cases in Massachusetts. Gargan and Bannister are two of the most published researchers on whiplash injuries.
The Study: Chronic Symptoms Are Not Unusual
The authors began with an important observation: 43% of patients may experience long-term symptoms following whiplash injury.
That statistic challenges a common assumption in personal injury cases—that uncomplicated whiplash should simply resolve within a few weeks.
The researchers evaluated 28 patients referred with chronic whiplash syndrome. These were not patients receiving chiropractic treatment immediately following their accidents. They were individuals whose symptoms had persisted and become chronic.
The patients were classified according to the severity of their symptoms before undergoing chiropractic treatment. Their clinical status was then reassessed following care.
The result was striking:
26 of the 28 patients improved following chiropractic treatment.
That represents approximately 93% of the study population.
The authors found a statistically significant improvement in symptom classification following treatment and concluded that the results justified further investigation through a prospective randomized controlled trial.
Why This Matters to Massachusetts Personal Injury Attorneys
Consider the typical rear-end collision case in Boston.
Your client is stopped in traffic on Storrow Drive, the Massachusetts Turnpike, Route 93, or somewhere in downtown Boston when another vehicle strikes them from behind.
First, persistent symptoms do not automatically mean that the patient’s complaints are unrelated to the original collision.
A patient may continue experiencing neck pain, headaches, stiffness, shoulder symptoms, or other complaints long after the vehicle has been repaired and the acute phase of the injury has passed.
The passage of time alone does not explain the underlying source of those symptoms.
Second, the study demonstrates something attorneys frequently encounter in practice: a patient may continue to improve even after symptoms have become chronic.
That becomes important when evaluating treatment duration, medical necessity, future care, and claims that a patient should have recovered simply because several months have passed.
The Imaging Problem
Whiplash cases can also become difficult because the severity of a patient’s symptoms may not correspond neatly with routine imaging. This also why a specialist orders important extra x-ray views to visualize instability caused by ligament injury.
A patient doesn’t need a fracture to have sustained an injury.
Whiplash can involve cervical joints, muscles, ligaments and other soft tissues. Consequently, the absence of a fracture on an emergency-room X-ray should not automatically be interpreted as evidence that the cervical spine was uninjured.
For an attorney, this distinction can become particularly important when an insurer attempts to equate “no fracture” with “no injury.”
Those are not the same statement.
An Important Limitation
The Woodward study should not be overstated.
This was a retrospective study involving only 28 patients, not a large randomized controlled clinical trial. It does not establish that 93% of all chronic whiplash patients will improve with chiropractic care. Even though
In fact, the authors themselves called for a prospective randomized trial comparing chiropractic treatment with conventional treatment.
In this group of 28 patients with chronic whiplash symptoms, 26 improved following chiropractic treatment.
That’s a meaningful distinction when discussing scientific literature in a deposition, demand letter, mediation, or courtroom.
The Takeaway for Personal Injury Attorneys
Perhaps the most important lesson from this study is simple:
Whiplash can become chronic—but chronic does not necessarily mean untreatable.
When a client continues to complain of neck pain months after a collision, the better question may not be:
“Why aren’t they better yet?”
It may be:
“What structures were injured, why are the symptoms persisting, and has the patient received appropriate treatment?”
At Charles Street Family Chiropractic, we have treated motor vehicle collision patients in Boston since 1990. When attorneys need help understanding cervical biomechanics, persistent whiplash symptoms, treatment, or the medical literature surrounding a client’s injuries, a detailed chiropractic evaluation can provide valuable clinical context. When the evidence is provided by a specialist trained in auto crash dynamics, it becomes a very strong fact pattern to fight to preserve the rights of your clients.
