Impairment ratings and disability decisions are made as objectively as possible. Whenever they can, doctors try to use tests and measures to put a number or percentage to a patient's abilities and disabilities. Unfortunately, there isn't a single tool or test for use with all injuries and all people.

A disability is defined as a loss in the ability to engage in gainful employment. This decision isn't made lightly. You will probably see the medical doctor as well as other health care providers. A physical or occupational therapist or psychologist may test you. The results of all the tests are reviewed before a final decision is made.
