More than 40 million people in the United States consider themselves
to have a physical or mental impairment that significantly affects life activities.1 Clarifying the scope of impairment and disability
assessment has been increasingly addressed by the courts,2
the medical community,3 and workers' compensation
authorities.4 In the United States, the American
Medical Association's Guides to the Evaluation of Permanent
Impairment5 is the most commonly used
source for assessing and rating an individual's permanent impairments.
