During a jury trial for a personal injury claim arising from a motor vehicle accident, the plaintiff brought a motion to exclude portions of the defence orthopedic expert's proposed testimony.
The plaintiff objected to the expert testifying about symptom exaggeration and the theory of chronic pain syndrome (central sensitization).
Applying the Mohan and Abbey frameworks, the court allowed the expert to testify regarding symptom exaggeration, finding it within his clinical expertise.
However, the court excluded his opinions on central sensitization, ruling he lacked the necessary qualifications and his evidence failed the gatekeeper cost-benefit analysis.
The expert was also restricted from testifying about undisclosed research and cautioned to present his evidence professionally.
