Modified Rankin scale

The modified Rankin scale is commonly used to quantify functional outcome in individuals who suffer a neurological event. The scale was initially described by Rankin in 1957 to assess the outcome of cerebrovascular accidents 1. It has subsequently been modified 2,3 and has been used in a wide variety of clinical contexts (e.g. stroke, glioma and traumatic brain injury). 

The scale comprises six levels, from 0 to 5, of increasingly severe disability where 0-2 is generally considered a good outcome with individuals assuming complete functional independence. A modified Rankin score of 6 is often used to denote an individual who is deceased.
