The claimant, Ellen Oppenlander, 53 years old as of the date of hearing, is a registered nurse; Ms. Oppenlander received her bachelor's of science and nursing degree in 1981, and has worked as a nurse for the University of Missouri since 1982. Ms. Oppenlander worked in the labor and delivery unit of the University of Missouri hospital system and, after ten years in the labor and delivery unit, became a charge nurse for the unit. In 2007, Ms. Oppenlander worked as a labor and delivery charge nurse for 12 hour shifts on Saturdays and Sundays during the day and on Monday night.
On January 20, 2007, a Saturday, Ms. Oppenlander fell on the gravel driveway of her home after she returned from work; Ms. Oppenlander described the driveway as snowy and icy.
Ms. Oppenlander testified that she did not remember her fall, only that she was lying face down in the snow. Ms. Oppenlander received emergency medical treatment at the University Hospital and Clinic emergency room. Ms. Oppenlander described vomiting and a very bad headache. She was released to return home that night.
Ms. Oppenlander did not return to work until the following Saturday, January 27, 2007, when she resumed working her full shift and full schedule. On February 5, 2007, Ms. Oppenlander was again the charge nurse in the labor and delivery unit when, while carrying IV bags into a patient's room, she slipped in a puddle of water and she fell onto her left hip hitting the left side of her head on a metal bed frame. Ms. Oppenlander described the part of her head that was hit as below the left ear. Ms. Oppenlander again went to the emergency room where a CT scan was done, she was treated with medication and sent home. Ms. Oppenlander again described vomiting and nausea and a severe headache as well as a feeling of panic.
Ms. Oppenlander did not return to work the following weekend. Ms. Oppenlander went to the work injury department of the University of Missouri and was referred to Dr. Carol Crooks, a specialist in physical medicine and rehabilitation at Rusk Rehabilitation. Ms. Oppenlander received physical therapy, speech therapy, and occupational therapy, as well as medications, including Klonopin and Aricept. Ms. Oppenlander described ongoing headaches, insomnia, and anxiety. Ms. Oppenlander also received treatment with Dr. Stucky, a physiatrist, and Dr. Houghton, a psychiatrist. Dr. Houghton prescribed Cymbalta for Ms. Oppenlander. Ms. Oppenlander had been receiving treatment from Dr. Houghton since prior to her 2007 falls. In May of 2007 Ms. Oppenlander returned to work as a nurse in the labor and delivery unit. Ms. Oppenlander had difficulty remembering how to accomplish work tasks that she had performed previously and was ultimately terminated from her position in the labor and delivery unit. Ms. Oppenlander then found employment in the utilization review department of the University of Missouri where her job was to interface with insurance companies to confirm and facilitate payment for treatment provided by the University of Missouri. Ms. Oppenlander was not successful in this position and was eventually terminated for poor performance. Ms. Oppenlander cited confusion and inability to operate office equipment as examples of her difficulty with this job.
Ms. Oppenlander was referred to Dr. Burger who prescribed Topamax for her headaches and vertigo; Ms. Oppenlander said that the headaches and vertigo symptoms improved with the Topamax. Similarly, the anxiety symptoms improved with the use of Klonopin.
Ms. Oppenlander began seeing Dr. Schneider, a psychologist, who started Ms. Oppenlander in group therapy as a referral from Dr. Stucky. Dr. Stucky's notes reflect that psychotherapeutic group treatment with Dr. Schneider would be an "adjunct" to Dr. Stucky's treatment. Dr. Schneider's therapy records and bills in the amount of $\ 1,541.73 for therapy for Ms. Oppenlander are in evidence.
Currently, Ms. Oppenlander suffers from tinnitus, an inability to process and retain information, and lack of memory, all symptoms from which she has suffered since her fall on February 5, 2007. Ms. Oppenlander described taking Cymbalta prior to her work injury, then taking an increased dosage for a time after the accident and injury, and then again being on a decreased dosage.
In May of 2009, Ms. Oppenlander fell; after the fall Ms. Oppenlander experienced feelings of mania, which included binge eating, spending excess amounts of money, and driving too fast; Ms. Oppenlander saw Dr. Slaughter regarding her symptoms and was put on Lithium which has helped control the manic sensation.
Prior to 2007, Ms. Oppenlander suffered the death of her mother from cancer after a long illness when Ms. Oppenlander was in college, the death of a sister in a motor vehicle accident, an out of wedlock pregnancy and adoption of the baby Ms. Oppenlander delivered while in college, an abusive father, and a difficult marriage in which her husband was abusive. Ms. Oppenlander received mental health treatment, including prescription medication, at various periods in her life to help her cope with these situations.
Since 2007, Ms. Oppenlander's father and a second sister have died.
Dr. Carol Crooks testified by deposition that she specializes in brain injury and stroke rehabilitation within her physical medicine and rehabilitation practice. Ms. Oppenlander came to Dr. Crooks as a referral from the employer/insurer on February 15, 2007. Dr. Crooks was aware of both of Ms. Oppenlander's falls in early 2007 and described the first fall on January 20, 2007, as "either mild or no head injury" according to the Glascow Coma scale which was used to describe initial head injury severity. Dr. Crooks stated that Ms. Oppenlander would have a similar rating on that scale after the February fall. Dr. Crooks stated that a brief loss of consciousness does not directly determine the outcome of a brain injury.
Dr. Crooks was aware of Ms. Oppenlander's attempts to return to work and recommended a neuropsychological evaluation for Ms. Oppenlander when it appeared that Ms. Oppenlander needed more supervision than was offered to her. Dr. Crooks defined a neuropsychological evaluation as developing "a neuropsychological profile outlining cognitive and psychological weaknesses of an individual patient from intellectual functioning to ability to pay attention, multi-tasking, processing speed." Dr. Crooks testified that she uses the testing to assist her in returning patients to school or employment and to recommend "adaptive measures." Dr. Crooks
stated that the neuropsychological testing revealed Ms. Oppenlander to have "pretty on par" neurocognitive function, but that she had difficulty with higher level "cognitive flexibility issues and difficulties with working memory, attention, and immediate verbal memory and just the higher level cognitive processing. What that translates to is given a structured environment with minimal tasks, she performed very well. But when you started adding distracting factors, she breaks down." Dr. Crooks found the neuropsychological test results to be consistent with what she identified in her treatment of Ms. Oppenlander.
Dr. Crooks opined that Ms. Oppenlander had preexisting depression, panic disorder, and obsessive compulsive disorder and that it was the combination of these preexisting psychiatric issues, the January 2007 head injury, and the February 2007 head injury which caused Ms. Oppenlander to be permanently and totally disabled. However, Dr. Crooks went on to say with a reasonable degree of medical certainty that the second fall, the fall on February 5, 2007, caused Ms. Oppenlander's significant cognitive impairment. With regard to the first fall on January 20, 2007, Dr. Crooks said that that fall put Ms. Oppenlander at a "higher risk for greater consequences from the second fall." According to Dr. Crooks, "It's not the injury itself, it's the brain that the injury happens to, in addition to the injury."
Dr. Raymond Cohen, board certified neurologist, testified by deposition that he evaluated Ms. Oppenlander on June 30, 2008, and issued a report regarding the evaluation on January 9, 2009. When Dr. Cohen saw Ms. Oppenlander she identified complaints related to the February 5, 2007 fall as headaches, tinnitus, lack of memory, anxiety, and depression, and an inability to return to employment, and lack of balance. Dr. Cohen noted headaches associated with hormonal changes and depression as issues for Ms. Oppenlander prior to the February 5, 2007 fall. Dr. Cohen opined that Ms. Oppenlander is permanently and totally disabled "due to the combination of her preexisting significant psychiatric conditions, along with the primary work-related injury of 2/5/07." Dr. Cohen noted that any disability from the January 20, 2007 fall would be "a minimal part of the overall head injury." In order of significance, Dr. Cohen found Ms. Oppenlander's cognitive deficits to be most significant, followed by post-traumatic migraines, tinnitus, severe fatigue, and unsteady gait. Dr. Cohen opined that as the result of the February 5, 2007 fall Ms. Oppenlander would need to continue medical treatment and prescription medications as described in Dr. Crooks' records for the rest of Ms. Oppenlander's life.
Dr. Dale Halfaker, licensed psychologist, testified by deposition that the majority of his practice "involves evaluating and assessing patients, especially patients with brain injury." Dr. Halfaker authored a report regarding his evaluation of Ms. Oppenlander on January 26, 2010, after seeing her in December of 2009. Dr. Halfaker described "second impact syndrome" which results from the impact of a second blow to the head in close proximity in time, causing "a much more significant impact on the person's ability to function across time than either of these two injuries alone." Dr. Halfaker described Ms. Oppenlander as suffering from the synergistic effect of two brain injuries close together along with "emotional factors that enter the picture and further complicate things." Dr. Halfaker described the two head injuries in early 2007 as well as dysphoria, psychological stress, and other emotional factors as barriers to Ms. Oppenlander's vocational success. Dr. Halfaker described an apportionment of Ms. Oppenlander's disabilities, including preexisting disabilities that "absent the brain injury and the trouble adjusting to the brain injury, [Dr. Halfaker] would have expected [Ms. Oppenlander] on a pre-injury basis to be
able to pull herself together, surmount, and deal with..." During cross-examination Dr. Halfaker discussed the apportionment issue stating that the ten percent disability from the second injury, the February 5, 2007 fall, for exacerbation of emotional issues is explained by Ms.
Oppenlander's ability to function well after her first fall in January of 2007, "and it's not until we get the second impact in that second injury that we get the greater degree of impairment. So I think had she not had the second injury, that she would have more than likely gone on and been just fine." Dr. Halfaker did not believe that Ms. Oppenlander is permanently and totally disabled, but did feel that she could not return to a highly stressful nursing position. Dr. Halfaker noted that Ms. Oppenlander had a fall in May of 2009, which resulted in Ms. Oppenlander's episodes of hypomania and need for treatment with Lithium.
Phillip Eldred, a certified rehabilitation counselor, testified by deposition that he evaluated Ms. Oppenlander on October 13, 2009. Mr. Eldred opined that Ms. Oppenlander is "permanently and totally disabled as a result of her injury on February 5, 2007 combined with her pre-existing injuries and medical conditions."
Dr. Thomas Martin, board certified in clinical neuropsychology and rehabilitation psychology, evaluated Ms. Oppenlander on June 18, 2009, and issued reports regarding his evaluation on June 18, 2009 and July 11, 2009. Dr. Martin opined that "Ms. Oppenlander's two traumatic brain injuries incurred in the beginning of January 2007 contributed to the onset of mild cognitive dysfunction and significant emotional distress that may be related to a shaken self-concept resulting from her failed return to work. This evaluation suggests that Ms. Oppenlander's primary barrier to vocational success is her psychological distress with her dysphoria likely to compromise her ability to comprehend, remember, and perform simple to moderately complex vocational tasks on a consistent basis." Dr. Martin opined that Ms. Oppenlander possesses "the cognitive abilities needed to sustain competitive employment" but needs "enhancement in psychiatric status." Dr. Martin recommended medical and psychiatric management of Ms. Oppenlander's health, noting Ms. Oppenlander's headaches, tinnitus, lack of coordination, and psychological issues.
Dr. Patrick Hogan, a board certified neurologist, testified by deposition that he examined Ms. Oppenlander on November 29, 2010, and authored a report of the same date. Dr. Hogan opined that Ms. Oppenlander's "neurological PPD would be 1 % on a subjective basis only, not related to organic brain disease."Dr. Hogan also found that Ms. Oppenlander "is able to work at her usual tasks of nursing on a neurological basis but once again I would depend upon a psychiatrist to determine whether she is able to work because of her psychological disturbances." Dr. Hogan answered claimant's counsel's questions regarding Dr. Hogan's distinction between emotional problems and organic brain disease by stating at one point that a person that is malingering or has emotional problems will put the wrong adjectives with nouns on the mental status exam and later stated that a person with organic brain disease will "switch the adjectives around." Dr. Hogan's explanations with regard to this distinction were confusing and nonsensical. A similar discussion occurred with regard to the source of Ms. Oppenlander's headaches which Dr. Hogan stated occurred as the result of the psychological stressors in Ms. Oppenlander's life rather than her fall, but could not describe the difference in the headaches.
Dr. Wayne Stillings, physician and psychiatrist, testified by deposition that he saw Ellen Oppenlander on January 30, 2008, and again on January 5, 2011. Dr. Stillings concluded that Ms. Oppenlander's fall on January 20, 2007, was the more serious of the two falls in early 2007, in part because of the loss of consciousness associated with that fall as opposed to the February 5, 2007 fall which was not associated with loss of consciousness; however, Dr. Stillings did say that the February 5, 2007 fall could have added to her complaints from the January 20, 2007 fall. Dr. Stillings found Ms. Oppenlander to have a permanent disability of one to two percent of the body as the result of the aggravation of Ms. Oppenlander's "pre-existing dysthymic disorder." Dr. Stillings opined that Ms. Oppenlander is fully able to work without restrictions and that she needs no "additional neuropsychiatric treatment, including medication or therapy." Dr. Stillings opined, based on MMPI-2 test results run on a forensic setting, that Ms. Oppenlander had an "invalid profile." "She responded to the MMPI-2 items in an exaggerated manner, endorsing a wide variety of symptoms and attitudes." When questioned about the MMPI-2 test and what qualifies as an "invalid profile" by counsel for Ms. Oppenlander, Dr. Stillings was less than forthcoming in his explanation, stating "What do you want to know here? I mean I don't understand why you're asking all these questions about the MMPI-2. It's clearly an invalid profile" and "Because it says right here, page 2, it's an invalid profile because F is greater than 89. Okay?"
Mr. James England testified by deposition that he is a rehabilitation counselor. Mr. England met with Ms. Oppenlander on November 20, 2008, and interviewed Ms. Oppenlander by telephone on March 14, 2011. Mr. England stated that opinions regarding Ms. Oppenlander's functional ability varied greatly, from Dr. Crooks' findings which would rule out a return to work because of "the combination of her ... two traumatic brain injury incidents" and Dr. Stillings' opinion which would allow a return to work "doing essentially any type of work that she was normally suited for."
Gary Weimholt, a vocational rehabilitation consultant, testified by deposition that he reviewed depositions and medical records pertaining to Ms. Oppenlander's work injury of February 5, 2007, as well as her ability to engage in gainful employment. Mr. Weimholt opined that as the result of the February 5, 2007 accident and injury Ms. Oppenlander is not able to return to her work as a nurse in the labor and delivery room and is similarly unsuited for a "skilled job ... [which is] highly detailed and complex" such as the utilization review job Ms. Oppenlander performed after her return to work after the February 2007 fall. Mr. Weimholt opined that Ms. Oppenlander is "employable in less detailed and complex forms of work, including jobs in a medical setting, which would include medical file clerk, medical office assistant, hospital patient representative or admitting clerk, medical appointment clerk and scheduler. These jobs would be somewhat detailed but not as complex as the work of a utilization reviewer or other skilled nursing work. These less complex jobs would also be more structured, fairly routine, require less independent judgment and decision making." Mr. Weimholt also noted other jobs which would be appropriate for Ms. Oppenlander outside of the medical field, such as "simple cashiering type jobs and other retail sales work" and "the work of a hotel and motel clerk and hotel night auditor" as well as "food service worker in cafeterias or dietary services."
Kelly Scheaffer, a labor and delivery unit nurse who worked with Ms. Oppenlander prior to her February 5, 2007 fall, testified to Ms. Oppenlander's competence as a labor and delivery nurse
