The employee's husband, Marvin Taylor, also testified at the trial. The employee, Glennda Taylor, was 46 years on the date of the hearing. She has completed the 10th grade and has earned a GED. She has a work history of various employment including cashier work, warehouse work, fast food work, and some production work. She has earned her real estate license although she has never used that license professionally. Additionally, Ms. Taylor was a homemaker at different periods of time. Ms. Taylor did not have any work-related injuries until she was working at Longview Community College between 1990 and 1993 doing clerical activities and experienced a fall at work. This resulted in a distal and proximal spiral tibial fracture. It involved an extended recovery. Bone grafting from the pelvic area and intramedullary rod placement were performed to achieve healing. The rod has since been removed. As a result of this injury Ms. Taylor continues to walk with a limp.
Her employment history continued with various and multiple employers including positions as a mailroom clerk, cook, bus driver, clerical, and assembly worker. She was employed at Kemper Insurance when she developed bilateral carpal tunnel syndrome and had bilateral carpal tunnel release surgeries in approximately 2001. Those surgeries were not handled through workers' compensation. Ms. Taylor began working at Ballard School District for the second time on October 1, 2002. She worked as a bus driver. She also began a second job at Wal-Mart as a cashier beginning in November of 2002. In April of 2003 she was moved to the floor in the ladies wear department. She did do some stocking activities as well as assembly and disassembly of hanging racks. She last worked at Wal-Mart in July of 2003.
The claimant describes her work at Ballard School District as in her own mind the source of the development of her back pain as well as the progression of that back pain. She attributes this to the rough surface on the rural gravel roads and she describes a washboard-type effect where she would be bounced in her seat. The bridges over which she drove also have rough surfaces on entry and exit. The claimant's husband, Marvin Taylor, testified at hearing that he had helped work on the Ballard School District buses that the buses were eight to ten years old and that none of these buses had shock absorbers or
suspension systems that he knew of. He indicated that a bus would be broken down once or twice a month. He had, in fact, driven one year for Ballard School District in 1991. He indicated that Bus 9, which the claimant drove, had a manual shift. He testified that he had taken pictures which are indicated as Koprivica Exhibits A1 through A14N along his wife's regular bus route.
Mr. Taylor testified that the photograph marked as Exhibit A14F shows the bridge higher than the road level with approximately $71 / 2$ to 8 inch difference in height. He said that it was like coming off a curb. Mr. Taylor took pictures along the whole route to give a general representation of the entire route. He also used an aluminum concrete leveler in some pictures to help accurately show the road unevenness. He took those photos on a single day in the spring. He said that the county roads on which she drove were graded twice a month and the potholes filled with loose gravel. He testified that his wife drove two times a day five days a week.
Mr. Taylor also stated that three to four months after she started driving she complained of pain in her leg. The claimant had progression of numbness and pain into both legs as well. Initially the problem started In the right hip, but then progressed to where it was affecting both legs. One of her concerns was the safety of driving a bus because of the profound numbness as she would drive. As a result of the problems with her legs she was not able to perform the floor tasks required at Wal-Mart. She attempted to find a different position with Wal-Mart which was not offered. She was eventually terminated from that employment. Initially the claimant did not comprehend that her problems arose from her low back. She erroneously believed that they related to a bone graft taken from her pelvic area as a result of the leg fracture ten years earlier. The claimant did have a history of going to a chiropractor as a child which is why she initially sought chiropractic care. The chiropractor, Dr. Porter, recorded difficulties associated with her having to drive a different bus. The claimant first made these complaints to Dr. Porter on December 6, 2002. She then treated with her family physician, Dr. Alexander for "leg cramps" and pain in her back. He then referred her to Dr. Carroll who saw her on July 8, 2003. Dr.Carroll suspected lumbar radiculopathy and ordered electrodiagnostic studies which revealed abnormalities consistent with right lumbar radiculopathy.
On July 23, 2003, an MRI scan was ordered which indicated degenerative disk disease as well as a focal disk herniation at L4, L5 and a more prominent disk protrusion that was posterolateral to the right at L5-S1 with some S1 nerve root impingement. The claimant received epidural steroid injections which were unsuccessful in improving her symptoms. The claimant took medical lea
