[MUSIC]. This video shows the instructions on how to score the RACE Scale. The RACE scale evaluates 5 items. 1, Facial palsy. 2, Arm motor function. 3, Leg motor function. 4, Head and gaze deviation. 5, Aphasia, that must be evaluated if the patient has right hemiparesis, or with no motor impairment. Or Agnosia, that must be evaluated if the patient has left hemiparesis. [MUSIC] To evaluate the facial palsy, ask the patient to smile or to show his or her teeth. Score the symmetry of the patient movement. >> [FOREIGN] >> Score 0 if facial movement is normal and the gesture when showing the teeth or smiling is symmetrical. >> [FOREIGN] >> Score 1 if facial gesture when showing the teeth or smiling is slightly asymmetrical. Score 2 if facial gesture when showing the teeth or smiling is completely asymmetrical. If the patient does not understand or cannot collaborate, application of pressure with the fingers behind the ears can provoke facial grimacing. [MUSIC] To evaluate arm hemiparesis, ask the patient to raise the arm 45 degrees if the patient is in supine position or 90 degrees if he or she is sitting. If the patient does not cooperate, extend his or her arms up. Score according to the time the patient can maintain his arms against gravity without touching the bed or. >> [FOREIGN] >> Score 0 if the patient can maintain the arms against gravity up to 10 seconds. >> [FOREIGN] >> Score 1 if the patient can maintain the arms less than 10 seconds. >> [FOREIGN] >> Score 2 if the patient cannot maintain the arms against gravity and drops immediately. [MUSIC] To evaluate leg hemiparesis, ask the patient to raise each leg 30 degrees, with the patient in supine position. If the patient does not cooperate, lift the legs up. Score according to the time the patient can maintain the leg against gravity, without touching the bed or the board where he is sitting. >> [FOREIGN] >> Score 0 if the patient can maintain the leg against gravity up to 5 seconds. >> [FOREIGN] >> Score 1 if the patient can maintain the leg less than 5 seconds. [MUSIC] Score 2 if the patient cannot maintain the leg against gravity and the leg drops immediately. [MUSIC] Observe eyes and head deviation to one side. If the sight is present, the direction of the deviation is to the contralateral side of the hemiparesis. Score 0 if absent, no head or gaze deviation is observed. Score 1 if present, eyes or head deviation to one side is observed. [MUSIC] To evaluate this and asomatognosia, first evaluate if the patient recognize his or her left part of the body. Ask the patient, who's arm is this? While showing him or her the paretic arm. Patients with asomatognosia do not recognize the left part of the body. Secondly, evaluate if the patient is aware of the weakness. Ask the patient, can you move your arms and clap your hands? Patients with anosognosia do not recognize their weakness. >> [FOREIGN] >> [FOREIGN] >> [FOREIGN] >> [FOREIGN] >> [FOREIGN] >> [FOREIGN] >> Score 0 if there is no asomatognosia nor anosognosia. >> [FOREIGN] >> [FOREIGN] >> [FOREIGN] >> Score 1 if there is asomatognosia or anosognosia. >> [FOREIGN] >> [FOREIGN] >> [FOREIGN] >> [FOREIGN] >> [FOREIGN] >> [FOREIGN] >> Score 2 if there is asomatognosia and anosognosia. >> [FOREIGN] >> [FOREIGN] [MUSIC] >> To evaluate the aphasia, ask the patient two orders that will always be the same, close your eyes and make a fist. Note that some patients might have aphasia without hemiparesis. [MUSIC] >> [FOREIGN] >> Score 0 if performs both tasks correctly. >> [FOREIGN] >> Score 1 if performs one task correctly. >> [FORIEGN] >> Score 2 if performs neither tasks. [MUSIC] Total score of the RACE Scale goes from zero to nine points. A score equal or higher than four is highly predictive of a large vessel occlusion. Remember that there is an app to evaluate the RACE Scale. Also, you can find more information about the RACE Scale in our web page [MUSIC]
