Minor ischemic stroke（ MIS） is considered to be a mild， non-disabling stroke， but its high recurrence rate often leads to poor prognosis. Functional Independence Measure（ FIM） are commonly used to measure motor and cognitive functions in patients to assess the functional independence. The severity of the stroke， whether or not using intravenous thrombolytic therapy and other factors have a certain impact on the patient functional independence and prognosis. This article reviews the factors that affect the functional independence of patients with MIS.
