Impairment Calculator 4th edition

Impairment Calculator 4th edition

EPI 4 is a specialist App designed to be used in conjunction with the American Medical Association’s ‘AMA Guides™ to the Evaluation of Permanent Impairment - fourth edition’.

The sole purpose of this App is to calculate the AMA Guide’s Upper Extremity Impairment Evaluation Records, Part-1 (Hand) and Part-2 (Wrist, elbow, and shoulder).

This App IS NOT associated with or endorsed by The American Medical Association. AMA Guides™ is a trademark of the American Medical Association. The trademark symbol has been omitted from the body of this text to improve readability.

Before using this App for medico legal purposes, the user should verify, through comparison with their own calculations, that the scope and accuracy available from the App is sufficient for their needs, including any additional requirements that may apply for their local jurisdiction.
