Based on a comprehensive review of all the testimony and evidence, I find as follows:
The employee has been employed with the employer for some 29 years. Throughout that entire time period, she has worked as an insurance billing clerk with job duties of answering the telephone, dealing with patient and insurance claims, typing and using the keyboard for the most part of the day.
Employee testified that she began experiencing problems with her hands as far back as 1997 and had gone to the Hannibal Clinic for occasional numbness and tingling in her hands. She was not tested at that time, but was given splints to wear. Around the year 2000, the employer made some ergonomic changes, including putting the keyboards under the desk. Prior to that change, the keyboard had been on the desk and the employee's hands were in an awkward position when typing. Although she did not receive any other treatment for her hands from 1997 until 2000, her hands got progressively worse and she noticed increased symptoms, including more numbness and waking her up at night.
Employee saw Dr. Gysbers for an evaluation in 2000 and had nerve conduction studies performed at that time, which
confirmed bilateral carpal tunnel syndrome. She was referred to Dr. Bukstein, a surgeon, and he scheduled surgery for the right hand in September 2000. The employee was unable to have the surgery done in September, so it was rescheduled and performed on November 30, 2000. She later had surgery on the left hand on February 8, 2001.
While the surgeries did provide some relief, she continued to experience problems, more with the left than the right, but did not have any more treatment until 2002, hence the 02-024100 claim. She then saw Dr. Oullette in March of 2002 and the doctor suggested she return to Dr. Bukstein to determine if her complaints were related to the carpal tunnel. Dr. Bukstein recommended repeat nerve conduction studies. Apparently due to Reliance going through liquidation, authorization to repeat the studies was not given for nearly 17 months after the recommendation. The studies were ultimately performed and Dr. Bukstein noted improvement, although employee was still having symptoms. The doctor did not recommend any additional treatment for the carpal tunnel syndrome.
At the hearing, employee testified that the surgeries did provide some relief, but she still has problems with dropping things, decreased sensation to hot and cold, left hand complaints radiating up to the elbow, mild loss of feeling in the right palm with some swelling and numbness. Her left hand ring and middle finger still go numb on occasion. She also stated that the ergonomic changes had helped as well since she does not have to have her hands in an awkward position now when she does the keyboarding.
The medical treatment for the surgeries and eventually the repeat nerve conduction studies were paid by Reliance or the Missouri Property \& Casualty Insurance Guaranty Association following Reliance's liquidation.
Dr. Strecker examined the employee at the request of Reliance/MIGA in April 2007. Dr. Strecker concurred with the diagnosis of bilateral carpal tunnel syndrome and that the treatment rendered was necessary and reasonable. However, the doctor opined that he did not feel the carpal tunnel was causally related to work based on his interpretation of recent medical literature indicating that repetitious keyboarding activity does not cause carpal tunnel syndrome. Rather the doctor felt the cause or causes in this instance were one or more of age, sex, being post menopausal and being overweight. However, the doctor did acknowledge in his deposition that typing in an awkward position could be the significant factor in developing carpal tunnel syndrome. (Employer/Insurer Exhibit C, pgs. 15 \& 27). Dr. Strecker, while finding the condition was not work related, did assess a permanent partial disability of 5 % at the level of her wrist.
At employee's request, Dr. Volarich examined the employee in April 2006. Dr. Volarich noted that prior to ergonomic changes the employee was required to type on a keyboard on the top of her desk which was much higher than ergonomically advisable requiring the employee's hands to be in an awkward position for s
