Dr. Volarich evaluated the claimant on three occasions, July 28, 2010, November 4, 2011, and December 14, 2012. Dr. Volarich reviewed numerous records including diagnostic studies, operative reports, and treatment records and conducted a physical examination. He also performed numerous range of motion tests, both passive and active. See Dr. Volarich deposition pages 5-7. He also reviewed Dr. Stillings' report and the vocational report from Ms. Gonzalez. Dr. Volarich opined, "When you included psychiatric disabilities and his physical disabilities, he's permanently and totally disabled as a result of the combination of all his medical conditions." See Dr. Volarich deposition, page 10. He also testified:
Q. Dr. Volarich, when did Mr. Schroeder reach MMI in regards to his July $17^{\text {th }}$, '09, in jury? ...
A. It looks like on August 28, 2012. That's when he was released by Dr. Riew.
Q. Okay. And so those were after his ... 11/2/09 and His 3/3/11 injury?
A. Yes.
Q. So before those two injuries I just spoke of, he was not at MMI in regards to the 7/17/09 injury, correct?
A. Correct.
Q. And I understand you're saying combination with the physical and orthopedic; however, would you agree that the orthopedic standing alone regardless of any psychiatric disabilities, the orthopedic disability from the July 17, 2009 injury standing alone renders him permanently and totally disabled?
A. From just a physical standpoint, yes. See Dr. Volarich deposition, pages 10,11 .
Wayne T. Stillings, M.D.
On February 7, 2013, Dr. Stillings evaluated claimant for psychiatric disability after reviewing medical records, taking a medical history, and conducting a mental status examination. Dr. Stillings performed numerous tests on the claimant including the MMPI-2 test, MCMI-III, WTAR and WRAT3. Dr. Stillings diagnosed:
The three work injuries are the prevailing factors in causing Mr. Schroeder a mood disorder with an associated 10 % psychiatric permanent partial disability of the body as a whole, residual symptoms from a head injury with an associated 10 % psychiatric permanent partial disability of the body as a whole, and a pain disorder with an associated 5 % psychiatric permanent partial disability of the body as a whole;
Mr. Schroeder has the following pre-existing psychiatric disorders and disabilities:
(A) Low IQ with poor education achievement with an associated 15\% psychiatric permanent partial disability of the body as a whole. (B) Personality disorder with an associated 5 % psychiatric permanent partial disability of the body as a whole.
The two work injuries of 07/17/2009 and 11/05/2009 were hindrances or obstacles to employment/re-employment and combine synergistically with each other and with the 03/2011 work injury, causing Mr. Schroeder to be permanently and totally disabled from the work force. See Dr. Stillings deposition, page 9.
Dr. Stillings testified that the MMPI-2 and the MCMI-III give information about a person's personality and that those tests confirm pre-existing personality disorder.
