Virginia case law has consistently held that in order to prove an “injury by accident,” a claimant must show:
“(1) an identifiable incident; (2) that occurs at some reasonably definite time; (3) an obvious sudden mechanical or structural change in the body; and (4) a causal connection between the incident and the bodily change.” Chesterfield Co. v. Dunn, 9 Va. App. 475, 476, 389 S.E.2d 180, 181 (1990). “Repetitive activity” or “repetitive trauma” injuries are not covered by the Virginia Workers’ Compensation Act. However, in Van Buren v. Augusta County., 66 Va. App. 441 (2016), the Court of Appeals held that a firefighter who noticed neck and shoulder pain after a 45-minute rescue suffered an injury by accident. The Commission followed that decision in Dugger v. Riverside Regional Jail Authority, JCN VA00001117636 (Jan. 3, 2017), holding that the claimant proved an injury by accident where she noticed a swollen knee after engaging in 4 hours of physical tactics training. Those decisions suggested a fundamental change in the definition of “injury by accident.”
