What does the definition of 'disability' according to AMA Guides imply?

The definition of 'disability' according to the AMA Guides centers on the concept of an alteration in a person's capacity due to an impairment. This perspective emphasizes the functional limitations that a person experiences as a result of a physical or mental impairment, rather than focusing solely on the economic impact or loss of job status. Such alterations can affect various aspects of a person's daily life and their ability to perform work-related tasks, which is a central concern in the evaluation of disability.

This approach aligns well with the purpose of the AMA Guides, which is to provide a standardized methodology for assessing and describing disabilities so that the impact on an individual's functional capabilities can be clearly understood. By focusing on the change in capacity, the definition allows for a more comprehensive assessment and understanding of how an injury or condition affects a person's overall well-being and ability to engage in their usual activities, including work.
