The findings of fact and stipulations of the parties were accurately recounted in the award of the ALJ and, to the extent they are not inconsistent with the findings listed below, they are adopted and incorporated by the Commission herein.
Dr. Swaim saw employee on May 18, 2009, for the purpose of an independent medical evaluation. Dr. Swaim opined that employee sustained 35\% permanent partial disability of the body as a whole attributable to her low back injury of November 11, 2000, and 5 % permanent partial disability of the body as a whole attributable to her low back injury of May 4, 2001.
Dr. Swaim attributed the majority of employee's permanent partial disability to the November 11, 2000, injury because the objective testing by CT and MRI scans showed the broad-based disc protrusion at L4-L5 predated the May 4, 2001, injury. However, Dr. Swaim went on to opine that both the November 11, 2000, injury and the May 4, 2001,

injury were substantial contributing factors causing the necessity for Dr. Wilson's surgery and employee's failed back syndrome.
Dr. Swaim deferred to a vocational expert regarding employee's ability to compete in the open labor market.
Dr. Wilson, the treating physician, opined that employee sustained 12\% permanent partial impairment of the body as a whole, but did not apportion the disability between the two injuries. Dr. Wilson provided this opinion on April 17, 2002, and was not deposed.
The only vocational opinion in the case was provided by Ms. Titterington, who opined that employee is unable to compete in the open labor market. Ms. Titterington attributed employee's inability to compete in the open labor market to the combination of her November 11, 2000, injury, her May 4, 2001, injury, her low academic skills, her lack of transferable job skills, and her difficulty in attending work daily.
With respect to medical causation and the nature and extent of employee's permanent partial disability attributable to the May 4, 2001, injury, we find Dr. Swaim's opinions more credible than Dr. Wilson's. Dr. Swaim performed a thorough independent medical evaluation, prepared a report based on that evaluation, fully explained his opinions by way of deposition testimony, and assigned a clear apportionment of disability between the November 11, 2000, and May 4, 2001, injuries. Dr. Wilson, on the other hand, provided a 12 % permanent partial impairment rating without specifying whether said 12 % was a combination of the November 11, 2000, and May 4, 2001, injuries, or if it was all solely attributable to one of the injuries. In addition, Dr. Wilson's use of the "permanent partial impairment" standard is misplaced as Missouri Workers' Compensation Law requires findings of "permanent partial disability." Finally, unlike Dr. Swaim's opinions, Dr. Wilson's opinions were not supported by deposition testimony.
Based upon Dr. Swaim's expert opinion, employee's testimony, and the record as a whole, we find that as a result of the May 4, 2001, work injury, employee sustained 5\% permanent partial disability of the body as a whole. We further find that employee's November 11, 2000, injury resulted in 22.5 % permanent partial disability of the body as a whole and that said preexisting disability posed a hindrance and obstacle to her employment or reemployment.
Dr. Swaim opined in his May 18, 2009, report that "[employee] has most likely reached maximum medical improvement from treatment of the occupational injuries of November 11, 2000 and May 4, 2001...." Based on this opinion, we find that employee reached maximum medical improvement on May 18, 2009.
