Test	Data
1A: Level of consciousness	Alert; keenly responsive Arouses to minor stimulation Requires repeated stimulation to arouse Movements to pain Postures or unresponsive
1B: Ask month and age	Both questions right 1 question right 0 questions right Dysarthric/intubated/trauma/language barrier Aphasic
2: Horizontal extraocular movements	Normal Partial gaze palsy: can be overcome Partial gaze palsy: corrects with oculocephalic reflex Forced gaze palsy: cannot be overcome
3: Visual fields	No visual loss Partial hemianopia Complete hemianopia Patient is bilaterally blind
4: Facial palsy	Normal symmetry Minor paralysis (flat nasolabial fold, smile asymmetry) Partial paralysis (lower face) Unilateral complete paralysis (upper/lower face) Bilateral complete paralysis (upper/lower face)
5A: Left arm motor drift	No drift for 10 seconds Drift, but doesn't hit bed Drift, hits bed Some effort against gravity No effort against gravity No movement Amputation/joint fusion
5B: Right arm motor drift	No drift for 10 seconds Drift, but doesn't hit bed Drift, hits bed Some effort against gravity No effort against gravity No movement Amputation/joint fusion
6A: Left leg motor drift	No drift for 5 seconds Drift, but doesn't hit bed Drift, hits bed Some effort against gravity No effort against gravity No movement Amputation/joint fusion
6B: Right leg motor drift	No drift for 5 seconds Drift, but doesn't hit bed Drift, hits bed Some effort against gravity No effort against gravity No movement Amputation/joint fusion
7: Limb Ataxia	No ataxia Ataxia in 1 Limb Ataxia in 2 Limbs Does not understand Paralyzed Amputation/joint fusion
8: Sensation	Normal; no sensory loss Mild-moderate loss: less sharp/more dull Mild-moderate loss: can sense being touched Complete loss: cannot sense being touched at all No response and quadriplegic Coma/unresponsive
9: Language/aphasia	Normal; no aphasia Mild-moderate aphasia: some obvious changes, without significant limitation Severe aphasia: fragmentary expression, inference needed, cannot identify materials Mute/global aphasia: no usable speech/auditory comprehension Coma/unresponsive
10: Dysarthria	Normal Mild-moderate dysarthria: slurring but can be understood Severe dysarthria: unintelligible slurring or out of proportion to dysphasia Mute/anarthric Intubated/unable to test
11: Extinction/inattention	No abnormality Visual/tactile/auditory/spatial/personal inattention Extinction to bilateral simultaneous stimulation Profound hemi-inattention (ex: does not recognize own hand) Extinction to >1 modality
