(concurring). I agree with the majority opinion insofar as it affirms the Worker’s Com*252pensation Appeal Board’s order granting plaintiff an award of worker’s compensation disability benefits based on the aggravation of symptoms related to plaintiffs preexisting orthopedic disabilities. However, unlike the majority, I believe that McDonald v Meijer, Inc, 188 Mich App 210; 469 NW2d 27 (1991), and Siders v Gilco, Inc, 189 Mich App 670; 473 NW2d 802 (1991), were correctly decided. Accordingly, I would follow those cases, not because I am bound by Administrative Order No. 1994-4, but because I believe those cases correctly resolve the issue at hand.
