136 Marholin v. SAIF ORTEGA, P. J.

Claimant appeals from an order of the Workers’ Compensation Board (the board) denying him permanent partial disability for an accepted injury that occurred at work. The board found credible the findings of both the med- ical arbiter and the attending physician of no impairment attributable to the accepted condition and, thus, concluded that claimant did not qualify for permanent partial disabil- ity under ORS 656.214. After reviewing the record, we con- clude that the board’s findings were supported by substan- tial evidence and that the board correctly applied the legal standard. Accordingly, we affirm.

Claimant injured his left shoulder at work while moving a patient in bed in June 2021. Shortly thereafter, SAIF Corporation accepted claimant’s injury as a left shoul- der strain. Several doctors monitored claimant’s condi- tion and, in November, an independent medical examiner concluded that claimant’s remaining medical complaints were no longer attributable to the accepted condition as of September 2021. Claimant’s attending physician agreed with the independent medical examiner’s analysis. In February 2022, SAIF closed claimant’s compensation claim and found, based on a review of his medical records, that he was not entitled to permanent partial disability.

Claimant sought reconsideration and asked to be examined by a medical arbiter. Dr. Grunwald, who per- formed that examination, found that claimant’s range of motion was severely restricted, raising “concerns for a pos- sibly voluntary limitation during testing.” Additionally, claimant’s muscle strength was significantly less than what was reflected in his medical records. The arbiter was called upon to “indicate if the findings are valid for the purpose of rating impairment” and, if not, to provide detailed and spe- cific reasoning. His response was as follows: “During testing, the claimant demonstrate[d] a signifi- cantly diminished range of motion of the left shoulder. He also demonstrate[d] significant hypersensitivity to the light touch of the cervical spine, trapezius, and posterior shoul- der, which is out of proportion to what would be expected from an injury that occurred almost one year prior. There Nonprecedential Memo Op: 343 Or App 135 (2025) 137 are serious concerns of potential voluntary limitations and somatoform overlay and hypersensitivity. Upon records review claimant demonstrate[d] greater range of motion and strength than we are seeing on today’s examination.

Also, there is not noted to be significant hypersensitivity upon light touch as was noted on our exam today which is out of proportion to the nature of the injury of shoul- der strain and has not been noted in previous exams which again raises questions of somatoform overlay.”

The arbiter’s lack of further explanation in the form is con- sistent with a determination that all of the impairment findings are invalid.

The Appellate Review Unit (ARU), in an Order on Reconsideration, concluded that claimant was not entitled to permanent partial disability because the arbiter had determined that the impairment findings were invalid. In an Order on Review, an administrative law judge (ALJ) disagreed with the ARU’s analysis, but ultimately reached the same conclusion. Instead of relying on the arbiter’s examination, which the ALJ found to be unreliable, the ALJ found the assessment of claimant’s attending physi- cian, Dr. Wilson, to be more credible. Wilson concluded that claimant’s impairment was not due to the accepted condi- tion, but to other conditions reflected in the medical record.

The ALJ affirmed the ARU’s order, and claimant appealed to the board, which ultimately found, like the ARU, “that the record reflects that [the arbiter] considered the findings to be invalid.”

Claimant asserts on appeal that the board erred in finding that the arbiter’s examination supports the conclu- sion that the findings were invalid and that, consequently, there was no impairment to the accepted condition. He argues that the arbiter’s stated concerns about inconsisten- cies in the medical record compared with his own examina- tion and the disproportionate sensitivity and pain claimant was displaying did not render the findings invalid.

We review the board’s factual findings for sub- stantial evidence and its legal conclusions for errors of law.

ORS 183.482(8)(a) and (c). Upon closure of a claim for work- ers’ compensation, the insurer is tasked with calculating 138 Marholin v. SAIF the amount of disability benefits due to the claimant, if any, based on impairment. See ORS 656.262(7)(c) (2016), amended by Or Laws 2021, ch 47, § 1; Or Laws 2022, ch 73, § 2 (explaining the process for closing a claim). Impairment is defined as “the loss of use or function of a body part or system due to the compensable industrial injury or occu- pational disease determined in accordance with the stan- dards provided under ORS 656.726 * * *.” ORS 656.214(1)(a).

Impairment must be “established by a preponderance of med- ical evidence based upon objective findings.” ORS 656.726 (4)(f)(B). Impairment is established by findings of loss due in material part to the accepted condition, unless the medical arbiter determines that the findings are invalid. See OAR 436-035-0007(11) (June 7, 2022). When a medical arbiter is used, “impairment is established based on objective findings of the medical arbiter, except where a preponderance of the medical evidence demonstrates that different findings by the attending physician are more accurate and should be used.” OAR 436-035-007(5)(b) (June 7, 2022). In reviewing the record, the board is permitted to “draw reasonable infer- ences from the medical evidence * * *.” Benz v. SAIF, 170 Or App 22, 26, 11 P3d 698 (2000).

Here, the board’s application of OAR 436-035- 0007(11) was not legally erroneous, and its interpretation of the arbiter’s report was supported by substantial evidence.

In applying OAR 436-035-0007(11), the board reasoned that the arbiter’s report was sufficient to find claimant’s exam- ination findings invalid based on his explanation regarding “serious concerns” as to claimant’s potentially voluntary limitations, somatoform overlay, and hypersensitivity that was out of proportion to the nature of claimant’s injury, and ultimately accepted the arbiter’s validity determination.

Additionally, a worker is entitled to permanent partial disability “due to” or “resulting from the compen- sable industrial injury or occupational disease” under ORS 656.214(1). Where there is no evidence of any impairment, valid or otherwise, due to the compensable injury, no award is applicable.

Furthermore, to the extent that claimant argues that he is owed permanent partial disability based on findings of Nonprecedential Memo Op: 343 Or App 135 (2025) 139 loss unrelated to the accepted condition, that argument is foreclosed by the holding in Robinette v. SAIF, 369 Or 767, 784, 511 P3d 1074 (2022) (holding that a claimant is not entitled to permanent partial disability when the workplace injury is not a material contributing cause of the finding of loss).

Moreover, even if the arbiter’s opinion was rejected, claimant’s attending physician opined that there was no permanent impairment due to claimant’s accepted shoulder strain. Neither the medical arbiter panel nor the attending physician concluded claimant’s findings of loss were valid or related to his accepted left shoulder strain condition.

Affirmed.
