Chronic Pain versus Clinically Associated Sequelae

This week a MIG hold case, where the Tribunal acknowledges that although not incorporated into the schedule, the 6 criteria outlined in the AMA Guides for evaluating chronic pain are useful in assessing such.

Factor: Chronic Pain versus Clinically Associated Sequelae

In Hayes v. The Co-Operators (20-012245), Rachel Hayes was injured on July 8, 2017 after losing control of her motorcycle that reportedly fell over onto her. She sought removal from the MIG on the basis of chronic pain and the need for phsyiotherapy.

Hayes relied on an April 16, 2019 ultrasound of her right shoulder which indicated possibly tendinosis or perhaps articular side fraying/low grade tearing but no full-thickness tear.

Hayes also relied on the CNRs of Sports Medicine Specialist Dr. R. Arbeau that she has required repeat cortisone injections for her shoulder, and it was not a minor injury and continued to affect her quality of life and ability to work. Hayes also relied on Family Physician Dr. P. Dzongowski’s CNRs where he noted pain in her right knee and right shoulder to be treated symptomatically.

Co-operators submitted that Hayes failed to provide sufficient evidence of functional impairment or disability. Further, that these injuries fall within the defined minor injuries under the schedule.
They relied on an October 25, 2018 IE Report provided by Physiatrist Dr. J. Clifford, who opined that Haye’s pain complaints were due to deconditioning, recommended imaging of the right shoulder and right knee to rule out anything more serious. Subsequent imaging showed possible low-grade tendon tear in the right shoulder, and trace fluid on the right knee.

The Tribunal found:

  • Hayes, while continuing to complain of pain in the years following the accident, her treating practitioners’ CNRs, diagnostic imaging, and Insurer’s Examination report did not establish disabling pain or functional limitation.
  • Although the AMA Guides do not form part of the schedule, they are useful in assessing chronic pain. In this case ‘nothing in the applicant’s evidence establishes that, as a result of the accident, she: developed a dependency on prescription drugs or other substances; became dependent on others; experienced deconditioning due to disuse and or fear-avoidance of physical activity due to pain; withdrew from social contacts; was incapable of pursuing work, family or recreational needs; or, had any psychosocial sequelae.”
  • The partial tendon tear in the right shoulder was considered to be within the MIG’s definition of “sprain.”
  • “In short, the totality of the evidence establishes that the applicant’s injuries and clinically associated sequelae are within the MIG.
