title: A radiologist's guide to the clinical scales used in the 2015 Endovascular Stroke Trials and the Revised American Heart Association/American Stroke Association Guidelines for Endovascular Stroke Treatment.
abstract: In 2015, five trials demonstrated the efficacy of endovascular treatment for acute stroke, culminating in the revised American Heart Association/American Stroke Association (AHA/ASA) recommendations for stroke management. The different clinical scales used in these trials may be unfamiliar to emergency and on-call radiologists. The modified Rankin Scale was used to describe patient disability for prestroke assessment in three of the trials and for the 90-day follow up in all five trials. The Barthel index was used in one trial to score prestroke ability to perform activities of daily living. The NIH Stroke Scale was used as part of eligibility criteria in four of the stroke trials to assess pre-existing neurological deficits. Also, the modified Rankin Scale and the NIH Stroke Scale are used in the revised AHA/ASA recommendations. By understanding these scales, emergency and on-call radiologists will better appreciate the stroke patient's condition and will be able to more actively collaborate in the care of acute stroke patients.
