Scandinavian Stroke Scale
The Scandinavian Stroke Scale was designed for ease of use by non-neurologists1. It is simpler than the NIHSS and has comparable performance in predicting death or dependence after stroke 2. The degree of neurological impairment measured by the Scandinavian Stroke Scale has been shown to correlate with ASPECTS score severity in acute stroke 3.
Classification
- consciousness: 2 (reacts to verbal commands but not fully conscious) to 6 (fully conscious)
- eye movements: 0 (conjugate eye deviation) to 4 (no gaze palsy)
- arm motor power on affected side: 0 (paralysis) to 6 (raises arm with normal strength)
- hand motor power on affected side: 0 (paralysis) to 6 (normal strength)
- leg motor power on affected side: 0 (paralysis) to 6 (normal strength)
- orientation: 0 (completely disoriented) to 6 (correct for time, place and person)
- speech: 0 (only answers yes/no or less) to 10 (no aphasia)
- facial palsy: 0 (present) to 2 (none)
- gait: 0 (bedridden/wheelchair) to 12 (walks 5 m without aids)
Interpretation
Stroke severity has been graded using this scale as 4:
- mild: 43-58
- moderate: 26-42
- severe: 0-25
