The statute provides that a claimant is entitled to readjustment of an original disability award only upon a showing of aggravation of the claimant's condition. To establish aggravation a claimant must produce medical evidence to that effect based, at least in part, upon objective findings of a physician. See Dinnis v. Dep't of Lab. & Indus., 67 Wn.2d 654, 409 P.2d 477 (1965); Quine v. Dep't of Lab. & Indus., 14 Wn.App. 340, 540 P.2d 927 (1975).
