Linda Mayfield — ADJ10282592, ADJ10645796

Linda Mayfield sought SIBTF benefits in connection with a 2012-2013 cumulative trauma injury to her bilateral knees (52% PD), arguing that her preexisting internal conditions (asthma, diabetes, heart disease, gout, and arthritis) combined with the subsequent injury to render her 100% permanently and totally disabled. The WCJ found applicant did not establish a preexisting labor disabling disability and was therefore ineligible for SIBTF benefits under Labor Code section 4751, finding Dr. Anderson's opinions were not substantial evidence. On reconsideration, the Board agreed that applicant's internal conditions were labor disabling (since they were ratable permanent disabilities), but found the record lacking on whether those conditions actually preexisted the subsequent cumulative trauma injury. The Board granted reconsideration, rescinded the Findings and Order, and remanded for further development of the record on whether the internal conditions preexisted the CT injury ending June 13, 2013.
