AMA Guides that most accurately reflects the injured employee's impairment. (Almaraz/Guzman

AMA guides in reporting an applicant's WPI as long as they provide appropriate justification for
doing so. Impairment percentages estimate the impact of the impairment on the individual's overall
ability to perform activities of daily living, excluding work. (AMA Guides, p. 4.)
