Under Missouri Workers' Compensation law, the claimant bears the burden of proving all essential elements of his or her workers' compensation claim. ${ }^{14}$ Proof is made only by competent and substantial evidence, and may not rest on speculation. ${ }^{15}$ Medical causation not within lay understanding or experience requires expert medical evidence. ${ }^{16}$ When medical theories conflict, deciding which to accept is an issue reserved for the determination of the fact finder. ${ }^{17}$

In addition, the fact finder may accept only part of the testimony of a medical expert and reject the remainder of it. ${ }^{18}$ Where there are conflicting medical opinions, the fact finder may reject all or part of one party's expert testimony that it does not consider credible and accept as true the contrary testimony given by the other litigant's expert. ${ }^{19}

The word "accident" as used by the Missouri workers' compensation law means "an unexpected traumatic event or unusual strain identifiable by time and place of occurrence and producing at the time objective symptoms of injury caused by a specific event during a single work shift. An injury is not compensable because work was a triggering or precipitating factor." ${ }^{22}$
An "injury" is defined to be "an injury which has arisen out of and in the course of employment. An injury by accident is compensable only if the accident was the prevailing factor in causing both the resulting medical condition and disability. The "prevailing factor" is defined to be the primary factor, in relation to any other factor, causing both the resulting medical condition and disability." ${ }^{23}$ An injury shall be deemed to arise out of and in the course of employment only if it is readily apparent, upon consideration of all the circumstances, that the accident is the prevailing factor in causing the injury; and it does not come from a hazard or risk unrelated to the employment to which workers would have been equally exposed outside of and unrelated to the employment in normal non-employment life. ${ }^{24}$
The determination of the specific amount or percentage of disability to be awarded to an injured employee is a finding of fact within the unique province of the ALJ. ${ }^{25}$ The ALJ has discretion as to the amount of the permanent partial disability to be awarded and how it is to be calculated. ${ }^{26}$ A determination of the percentage of disability arising from a work-related injury is to be made from the evidence as a whole. ${ }^{27}$ It is the duty of the ALJ to weigh the medical evidence, as well as all other testimony and evidence, in reaching his or her own conclusion as to the percentage of disability sustained. ${ }^{28}$
Section 287.020.7, RSMo, provides that "total disability" is the inability to return to any employment and not merely the inability to return to the employment in which the employee was

engaged at the time of the accident. { }^{29}$ The main factor in this determination is whether, in the ordinary course of business, any employer would reasonably be expected to employ the employee in this present physical condition and reasonably expect him to perform the duties of the work for which he was hired. ${ }^{30}$ The test for permanent and total disability is whether the claimant would be able to compete in the open labor market. ${ }^{31}$ When the claimant is disabled by a combination of the work-related event and pre-existing disabilities, the responsibility for benefits lies with the Second Injury Fund. ${ }^{32}$ If the last injury in and of itself renders a claimant permanently and totally disabled, the Second Injury Fund has no liability and the employer is responsible for the entire compensation. ${ }^{33}$
Various factors have been considered by courts attempting to determine whether or not an employee is permanently totally disabled. It is not necessary that an injured employee be rendered, or remain, wholly or completely inactive, inert or helpless in order to be entitled to receive compensation for permanent total disability. ${ }^{34}$ An employee's ability or inability to perform simple physical tasks such as sitting, ${ }^{35} bending, twisting, { }^{36} and walking { }^{37}$ may prove that the employee is permanently totally disabled. An employee's age may also be taken into consideration. ${ }^{38}$
In order to find permanent total disability against the Second Injury Fund, it is necessary that the employee suffer from a permanent partial disability as the result of the last compensable injury, and that the disability has combined with a prior permanent partial disability to result in total disability. ${ }^{39}$ Where a pre-existing permanent partial disability combines with a workrelated permanent partial disability to cause permanent total disability, the Second Injury Fund is liable for compensation due the employee for the permanent total disability after the employer has paid the compensation due the employee for the disability resulting from the work-related injury. ${ }^{40}$ In determining the extent of disability attributable to the employer and the Second Injury Fund, an administrative law judge must determine the extent of the compensable injury first. ${ }^{41}$ If the compensable injury results in permanent total disability, no further inquiry into Second Injury Fund liability is made. ${ }^{42}$ Therefore, it is necessary that the employee's last injury be closely evaluated and scrutinized to determine if it alone results in permanent total disability and not permanent partial disability.

On September 1, 2009, claimant sustained a compensable injury by accident. This injury occurred during the course and scope of his employment with the employer. Claimant contends that he is permanently and totally disabled due to this work accident alone. The employer/insurer argues claimant is not permanently and totally disabled.
Dr. Sher, one of claimant's treating doctors, determined that claimant is totally disabled based on the severe headaches that resulted from the 2009 work injury. Both Dr. Shuter and Dr. Daniel agree claimant is permanently and totally disabled based on the primary (work) injury alone. Vocational expert Gary Weimholt opined claimant would not be employable in the open labor market based on the primary injury.
Dr. Selhorst examined claimant on behalf of the employer/insurer. Dr. Selhorst does not give an opinion as to whether claimant is employable. Dr. Selhorst diagnosed claimant with post-traumatic stress disorder, but he did not clearly identify the cause of that PTSD. Dr. Stillings disagreed that claimant had PTSD, and he opined that claimant did not have any neurological or psychiatric disability from the primary injury.
After considering all of the evidence, I find that claimant is permanently and totally disabled. Further, I find claimant is permanently and totally disabled due to the last injury alone. The opinions of Dr. Shuter, Dr. Daniel, Dr. Sher, and Mr. Weimholt were credible and persuasive on this issue. In addition, claimant was a credible and convincing witness.
At trial, the parties agreed that if the employer/insurer is found liable for permanent total disability benefits, the benefits should begin on January 21, 2010. Consistent with this stipulation, I find that the liability of the employer/insurer for permanent total disability benefits begins on January 21, 2010. As the employer/insurer has been found liable for permanent total disability benefits, the Second Injury Fund bears no liability in this case.
