I have read the briefs of the parties and reviewed the whole record. I have considered all of the competent and substantial evidence based on record as a whole. Based on my review of the evidence as well as my consideration of the relevant provisions of the Missouri Workers' Compensation Law, I find the employee has failed to prove that her work duties as an inventory clerk for employer's medical device and instrument manufacturing company caused her condition of bilateral carpal syndrome and need for treatment.
The undisputed testimony is that employee had problems with her left hand going back more than twenty years, before she even worked for employer. Employee also had some bilateral upper extremity complaints before employer assigned her to her present position.
Employee's initial description of her work activities, as conveyed to the medical experts, shaped the medical testimony in this case. Dr. Bruce Schlafly, employee's expert, was forced to rely on the job description employee gave him as he never had an opportunity to review employer's job task analysis. Dr. Schlafly admitted he accepted employee's description of her job activities as completely accurate. However, employee significantly overstated both the frequency of her activities and the force required to perform them. Employee advised Dr. Schlafly that she was opening up to 700 tubes per day to remove small tools. Based on this assumption, Dr. Schlafly concluded employee's work was the prevailing factor causing onset of her carpal tunnel syndrome.
However, even employee admitted that she opened nowhere near that many tubes. Employee testified she worked with the tubes approximately twice a week for thirty minutes each time. That represents a total of sixty minutes per week. Employee testified it took her approximately one minute to deal with each inventory item. Crediting employee's testimony, she opened no more than sixty tubes per week. In addition, employee admitted it was not necessary for her to open tubes unless the parts would not otherwise fit where they were to be stored. Jeanette Tucker, employee's direct supervisor at the time of her alleged injury, testified that employer received about forty tubes per week, not 700 per day. As demonstrated the photograph displayed on page 262 of the hearing transcript, the vast majority of the items employee received remained unopened in their tubes, demonstrating that she did not open nearly as many tubes as even her testimony suggested, and dramatically less than what Dr. Schlafly assumed. Accordingly, the facts Dr. Schlafly relied to arrive at his conclusion that employee's work was hand-intensive were fatally flawed.
Employer's authorized physician, Dr. Mitchell Rotman, also initially concluded that employee's work activities caused her carpal tunnel syndrome, although he was careful to condition this opinion on an assumption that employee had accurately described her work activities.¹ When Dr. Rotman had the benefit of the Coventry's objective analysis

of the essential functions and physical demands of material clerk, employee's position, he revised his earlier opinion to conclude that employee's work was not the prevailing factor causing her carpal tunnel syndrome. Dr. Rotman's ultimate conclusion, arrived at only after reviewing additional facts regarding employee's actual job duties should be deemed the more credible and accurate of the two expert medical opinions in the record.
In addition, there is another explanation of the cause of employee's bilateral carpal tunnel condition. Both Dr. Schlafly and Dr. Rotman agree that employee had three personal risk factors that placed has at significant risk of non-industrial carpal tunnel syndrome: her female gender, post-menopausal age, and obesity.
In order to establish a repetitive trauma injury arising out of and in the course of employment an employee must establish that her work was the prevailing factor. Employee has failed to do so. The medical expert retained by employee, who opined that employee's work was the prevailing factor causing her carpal tunnel syndrome and need for treatment, admitted he was operating under a misapprehension regarding employee's work activities. Contrasted with this, employer's expert Dr. Rotman, upon learning of employee's actual objectively verified job activities, concluded that her work was not the prevailing factor. Instead, Dr. Rotman concluded that employee's gender, age, and weight were more likely possible reasons for the onset of her condition.
For all of these reasons, the administrative law judge's finding that employee sustained an occupational disease/repetitive trauma arising out of and in the course of her employment should be overturned. Because the majority finds otherwise, I respectfully dissent.
