Claimant's testimony and the medical evidence require findings of self-contradiction, preexisting lumbar pathology, and overwhelming post-accident physical deterioration. Awarding PPD or PTD benefits in these cases requires ignoring Claimant's remarkable post-accident work record, the nearly year-long treatment gaps, his own credibility deficits, and his experts' omissions in foundation regarding the long treatment gaps and undisputed post-accident work record in forming their opinions. These weaknesses render them unpersuasive. Understandably, Claimant's experts could not have addressed Claimant's contradictions and admissions at trial. Claimant's trial admission that he could do anything (prior to working for AFRAM in January 2004) renders dubious either medical expert's assertion of a PPD percentage.
Medical causation, which is not within the common knowledge or experience of lay understanding, must be established by scientific or medical evidence showing the cause and effect relationship between the complained of condition and the asserted cause. McGrath v. Satellite Sprinkler's Sys., 877 S.W.2d 704, 708 (Mo. App. 1994). As with all proofs in complex medical evidence, a medical expert's opinion must be supported by facts and reasons proven by competent evidence that will give the opinion sufficient probative force to be substantial evidence. Silman v. Wm. Montgomery \& Assoc., 891 S.W.2d 173, 176 (Mo.App. 1995), citing Pippin v. St. Joe Mineral Corp., 799 S.W.2d 898, 904 (Mo.App. 1990). Any weakness in the underpinnings of an expert opinion goes to the weight and value thereof. Hall v. Brady Investments, Inc., 684 S.W.2d 379 (Mo.App. 1984).
The record contains unrebutted probative evidence that (1) Claimant worked full-time from 2004 to 2006, including two eleven month treatment gaps, and (2) Claimant developed cardiac pathology and cancer during the years following his employment with BNL. These facts, one set contemporaneous, the other remote, each independently break the causal chain of events that might link any of the three Claims herein as a substantial factor in Claimant's inability to work.
Direct examination included eliciting severe, diffuse, current complaints (in 2014) from Claimant followed by query and answer that none of this existed prior to 2003 (year of all three reported accident dates) without mention during the examination of onset dates and other explication of the eleven year lapse of time between 2003 and today's current complaints. (T. 30, 33.) Claimant did not have completely disabling pain in the neck, low back or limbs as evidenced by his working full-time for AFRAM and BNL, from 2004 to 2006, performing the same demanding tasks. On cross-examination by the SIF, in context of his unemployment application and disability onset, the following exchange took place:
Q: Okay. And do you remember, sir, when you applied for those benefits that they asked you for a date of onset of your disabling conditions?
A: Yes.
Q: And do you remember telling them that was around September $28^{\text {th }}$ of 2006?
A: Yeah, that's a good possibility.
Q: And do you remember on your application where they asked about how many hours per week you were working and how many days per week you were working at your last job?
A: Yes.
Q: Do you remember representing that you worked a full eight hour day, five days a week up until September 2006?
A: Yes.
(T. 59-60.) Thus, Claimant not only admitted these facts at trial but represented these facts to a third party, the employment security office, many years ago. Claimant expressly admitted deterioration while working for the subsequent employers, AFRAM and BNL. (T. 63.)
Claimant identified no new symptoms of the lumbar spine that might constitute additional permanent partial disability (PPD) as a result of any of the three reported accident herein. He had some cervical limitations that were rated by both medical experts at ten percent PPD.
Claimant's expert's opinions regarding causation and disability are much less probative to the extent each relied on Claimant's reports of symtomotology and the undisputed work record. Claimant's out-sized complaints are inconsistent with his own medical records exhibits, some trial admissions and the fact of uninterrupted work (no lost time). Regarding his ability to return to work full-time, Claimant said at trial he could not answer that question. (T. 46.)
Claimant offered no expert opinion of causation and resulting permanent disability that are reconcilable with Claimant's post-accident full-time, demanding work, the two treatment gaps, during the period 2004 to 2006, and credibility deficits. Dr. Volarich's testimony, as such in this case, lacks facts and reasoning that give his opinions of causation and disability probative force. Silman, supra. The significance of Claimant's post-accident work record (in all three cases) is impressive and the two, nearly year-long, treatment gaps in the years immediately subsequent to all three cases is inescapable. None of the three cases caused any temporary total disability and Claimant remained working unrestricted.
Dr. George's assignment of a ten percent PPD of the body referable to the cervical spine is, despite Claimant's credibility issues, easily balanced with the conservative treatment record during the Spring of 2003, during which no new lumbar symptoms were identified, or complained of, but where some minor cervical problems were treated until Claimant felt "much better" in June 2003. Dr. George's opinions are more persuasive than those of Dr. Volarich.
For the reasons stated, the record of evidence does not support a finding of permanent disability arising from the second or third cases.
