Biomechanical Expert

Biomechanical experts apply engineering and physiology to assess injury mechanism, evaluating whether the forces involved could produce a specific injury. They address causation mechanism rather than medical diagnosis.

The boundary with medical opinion is frequently litigated.

Alternative Names:

Biomechanics Expert, Injury Biomechanics Expert

Why it Matters?

The scope boundary is the recurring admissibility issue, since courts permit biomechanical testimony about forces and general injury mechanism while excluding opinions that a specific plaintiff was or was not injured, which is medical testimony requiring different qualifications. Framing the opinion as mechanism rather than diagnosis is what preserves it. These experts are most valuable in low-impact collision cases where the delta-v analysis addresses whether the claimed injury is plausible.
