Description

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

Parameter

Finding

2

 

marked paresis of finger extension and/or flexion

3

 

no finger flexion or extension

4

straight leg raising

normal power

1

 

against resistance but with reduced power

2

 

against gravity, but not against resistance

3

 

not possible

4

gait

normal

1

 

with a device (cane, walker, etc.)

2

 

with support of 1 or 2 persons

3

 

not possible

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%
