The Tennessee MIR Impairment Rating Report — 5tEditioTNNMMNIRISIR) is an assessment tool used by physicians to determine the level of functional impairment resulting from an injury or illness. It is used to rate the severity of an individual's physical disability or impairment caused by a medical condition or injury. The TNM IR is divided into two parts: the impairment rating and the functional capacity. The impairment rating includes ratings for range of motion, strength, and functional limitations. The functional capacity report lists the physical and mental abilities of the individual, and the level of impairment associated with each ability. There are three types of TNM IR: the Standard Impairment Rating, the Standard Impairment Rating plus Range of Motion, and the Custom Impairment Rating.
