An Impairment Rating is a numerical assessment used to evaluate the severity of a person's physical or mental impairment. This rating helps determine the extent to which an individual's ability to perform daily activities is affected by their condition. It is often expressed as a percentage, with higher percentages indicating greater impairment. Impairment ratings are commonly used in various fields, including workers' compensation, disability evaluations, and personal injury claims. Medical professionals typically conduct assessments based on established guidelines, considering factors such as the individual's medical history and the impact of the impairment on their life.
