Two witnesses testified at the hearing, claimant (whose deposition was also admitted into evidence) and Phillip Eldred, a certified rehabilitation counselor hired by claimant's attorney. The parties additionally presented into evidence claimant's medical records for her 1975 injury and her 1983 injury. In addition, the depositions of Dr. David Volarich, an occupational medicine specialist who is an examining and rating physician hired by claimant, and Michael Lala, a certified rehabilitation counselor, hired by the Second Injury Fund, were admitted into evidence.
Claimant's accidental injury occurred on January 21, 1983, whenshe slipped and fell while at work for Advanced Circuitry Division of Litton in Springfield, Greene County, Missouri. Claimant fell on her right hip, her back, and the back of her head. She began treatment almost immediately and has continued to treat for her condition through the date of the hearing. Claimant's treating doctors have provided her with conservative care (including prescriptive medications, injection therapy and blocks, and a chymopapin injection), a surgery on March 21, 1983, by Dr. Harmon, who performed a "[l]aminectomy L4-L5 interspace with removal of a herniated 4th lumbar disc and adhesiolysis of L5 interspace," and a second surgery, also performed by Dr. Harmon, on March 8, 1993, for "[b]ilateral decompressive laminectomy with foraminotomies, L4 and L5.
Claimant has been rated by Dr. Harmon, Dr. Janie Vale, and Dr. Volarich. On April 11, 1986, Dr. Harmon initially rated claimant as having a 20 percent disability to the body as a whole for her 1983 injury. On December 6, 1988, Dr. Harmon rated claimant as follows: "Please be advised that her over all disability, I think, is about 35 percent. In regards to after her first operation for disc removal it would have been in the neighborhood of 15 precent but having a resected herniated disc without significant sequela she now totals about 35 percent. I think this is not going to appreciably change with time." Later, on January 26, 1993, Dr. Harmon rated claimant's disability for the 1983 injury alone as follows: "The above named patient has been under my care due to a work related injury sustained on January 21, 1983, whileemployed with Litton Industries. Her overall disability as a result of this injury, is about 35 % in regard to her first operation for disc removal. It would have been in the neighborhood of 15 %, but having a resected disc without significant sequela, she now totals 35 %. I do not think that this will change appreciably with time." He did not again rate claimant even though he later performed surgery on her back on March 8, 1993, and continued to treat claimant thereafter for several years (through April 12, 1999).
On March 29, 1988, Dr. Janie Vale assessed claimant's disability from the 1983 injury alone as being 25 percent to the body a
