How Dr. Mulak Forms a Causation Opinion in a Motor-Vehicle Injury Case

A causation opinion should not begin with the assumption that every complaint after a collision was caused by the collision. It should begin with a method: what changed, when it changed, whether the mechanism is plausible, what the examination shows, what existed before the event, and whether another explanation fits better.

1. Establish the timeline

The timing of symptom onset matters. Immediate symptoms may support one type of relationship; delayed symptoms can still be clinically plausible in some injuries but require careful documentation. The history should distinguish what was present before the collision from what appeared or worsened afterward.

2. Consider the mechanism without overrelying on it

The collision history can help determine whether the reported injury pattern is biomechanically plausible, but vehicle damage or impact description alone does not diagnose injury. Mechanism is one part of the analysis, not a substitute for examination or medical evidence.

3. Compare the symptoms with the examination

A stronger clinical opinion exists when the patient’s reported symptoms are reasonably consistent with examination findings, functional limitations, imaging, and other objective data. Inconsistency does not automatically mean the patient is uninjured, but it should be acknowledged and investigated.

4. Review prior conditions and prior records

Pre-existing degeneration, previous accidents, prior neck or back pain, prior concussion, and other health conditions can affect causation and prognosis. A collision may cause a new condition, aggravate a prior condition, or be unrelated to a finding that was already present. The analysis should distinguish those possibilities when the information allows.

5. Consider alternative explanations

Causation reasoning should ask what else could explain the symptoms or findings. Medication effects, non-traumatic disease, prior injury, unrelated overuse, psychosocial factors, or another medical condition may contribute. A credible opinion considers alternatives rather than ignoring them.

6. Use testing as support, not as automatic proof

Imaging and objective measures can strengthen or weaken parts of the analysis, but an abnormal test does not automatically prove that the collision caused the abnormality. The significance of a finding depends on timing, prior records, known variability, clinical correlation, and the type of test.

7. State uncertainty when it exists

Not every case permits a high-confidence causation opinion. Missing prior records, delayed presentation, conflicting history, unrelated intervening events, or nonspecific findings may limit the conclusion. A transparent opinion should state those limits.

The same method can also support the conclusion that a reported condition or finding is not related to the collision when the timeline, prior history, alternative explanations, examination, or other evidence points away from a causal relationship.

8. Separate clinical causation from legal conclusions

Clinical causation addresses whether the collision more likely than not caused or aggravated a condition based on the available medical information and the applicable standard for the opinion being offered. Questions of liability, negligence, damages, and legal responsibility are separate.

At Cityside, the purpose of a causation analysis is to make the reasoning inspectable: the timeline, mechanism, findings, prior history, alternatives, and limitations should be visible to whoever later reviews the record.

How this works at Cityside: When Dr. Mark Mulak of Cityside Chiropractic provides a causation opinion, it addresses the timeline, mechanism, examination findings, prior history, and alternative explanations, and it states the limitations of the available information. The same method can lead to a conclusion that a condition is not related to the collision when the evidence points that way.
