Result Interpretation

The Scandinavian Stroke Scale, designed in 1985, includes 9 items such as level of consciousness, orientation, speech, eye movement, facial and limb paralysis, and gait.

The SSS is the most time-efficient and clearly defined scale, although it records fewer symptom progressions, these records have a significant impact on patient outcomes.
