What is Modified Rankin Score (mRS)?
In the original Rankin score proposed in 1957, there were 5 grades of stroke severity ranging from “no significant disability” to “severe disability’ [1]. Modified Rankin Score (mRS) has been used to quantify disability after recovery from a cardiac arrest [2]. The score ranges from for 0 with no symptoms to 6 which would mean mortality. In between there is 1 with no significant disability and 2 with slight disability. Moderate disability requiring some help is 3 and 4 is moderately severe disability in which the person is not able to walk or attend to bodily needs without help. Modified Rankin Score 5 indicates severe disability.
