The Copenhagen Stroke Scale is a rapid, valid and reliable scoring system for evaluating patients who have had a stroke. It can be used to assess the both the initial neurologic deficit and the subsequent course. The authors are from several hospitals in Copenhagen, Denmark.
Parameters:
(1) level of consciousness
(2) speech and comprehension (if right-sided hemiparesis)
(3) neglect (if left-sided hemiparesis)
(4) conjugate gaze deviation
(5) facial palsy
(6) visual field defect
(7) straight arm raising
(8) function of the hand
(9) straight leg raising
(10) gait

Instructions for scoring:
(1) If the level of consciousness is difficult to awake or cannot awaken, then score items 2 and 3 to have 4 points.
(2) Score speech and comprehension (item 2) only for patients with right-sided hemiparesis.
(3) Score neglect (item 3) only for patients with left-sided hemiparesis.
(4) If cooperation is poor, evaluate visual field defect (item 6) by hand movements in the suspected blind field. An absent blink reflex indicates a field defect.
stroke score =
= SUM(points for all of the applicable parameters)
Interpretation:
• minimum score: 10
• maximum score: 40 (if bilateral hemiparesis, with all 10 items), 36 (if unilateral, with 9 items), 32 (if no hemiparesis, with 8 items)
• The higher the score, the more severely the patient is affected.
percent of maximal score =
= ((total score) – (number of items)) / ((maximal score) – (number of items)) * 100%
