Study number:....................................... Inclusion date: / / (dd mm yyyy) Date: Time: Physician: BASELINE 24 48 HOURS Date: Time: Physician: Item: Description: Score: Score: 1a Level of consciousness. 0 = alert. 1 = not alert, but arousable by minor stimulation to obey, answer, or respond. 2 = not alert, requires repeated stimulation to attend, or is obtunded and requires strong or painful stimulation to make movements (not stereotyped). 3 = coma (unresponsive). 1b LOC questions. 0 = answers both questions correctly. 1 = answers one question correctly. 2 = answers neither question correctly. 1c LOC commands. 0 = performs both tasks correctly. 1= performs one task correctly. 2 = performs neither tasks correctly. 2 Gaze. 0 = normal 1 = partial gaze palsy. This score is given when gaze is abnormal in one or both eyes, but where forced deviation or total gaze paresis are not present. 2 = forced deviation, or total gaze paresis not overcome by the oculocephalic maneuver. 3 Visual. 0 = no visual loss. 1 = partial hemianopia. 2 = complete hemianopia. 3 = bilateral hemianopia (blind, including cortical blindness) 4 Facial palsy. 0 = normaal/symmetrical. 1 = minor paralysis (flattened nasolabial fold, asymmetry on smiling) 2 = partial paralysis (total or near total paralysis of lower face) 3 = complete paralysis of one or both sides (absence of facial movement in the upper and lower face) 5a Motor function. 0 = no drift, limb holds 90 for full 10 seconds. Left arm. 1 = drift, Limb holds 90, but drifts down before full 10 seconds 2 = some effort against gravity, limb cannot get to or maintain 90 3 = no effort against gravity, limb falls. 4 = no movement 9 = untestable (e.g. amputation); elaborate: 5b Motor function. 0 = no drift, limb holds 90 for full 10 seconds. Right arm. 1 = drift, Limb holds 90, but drifts down before full 10 seconds 2 = some effort against gravity, limb cannot get to or maintain 90 3 = no effort against gravity, limb falls. 4 = no movement 9 = untestable (e.g. amputation); elaborate: 6a Motor function 0 = no drift, leg holds 30 position for full 5 seconds. Left leg 1 = drift, leg falls by the end of the 5 second period. 2 = some effort against gravity; leg falls to bed by 5 seconds. 3 = no effort against gravity, leg falls to bed immediately. 4 = no movement. 9 = untestable (e.g. amputation); elaborate: 6b Motor function. 0 = no drift, leg holds 30 position for full 5 seconds. Right leg. 1 = drift, leg falls by the end of the 5 second period. 2 = some effort against gravity; leg falls to bed by 5 seconds. 3 = no effort against gravity, leg falls to bed immediately. 4 = no movement. 9 = untestable (e.g. amputation); elaborate: 7 Limb ataxia. 0 = absent. 1 = present in one limb. 2 = present in two limbs. 8 Sensory. 0 = normal. 1 = mild to moderate sensory loss. 2 = severe to total sensory loss. 9 Language. 0 = no aphasia 1 = mild tot moderate aphasia. 2 = severe aphasia. 3 = mute, global aphasia; no usable speech or auditory comprehension. 10 Dysarthria. 0 = normal articulation 1 = mild to moderate; patient can be understood with some difficulty. 2 = Severe; patient's speech is unintelligible in the absence of or out of proportion to any dysphasia, or is mute. 9 = Intubated or other physical barrier; elaborate:.. 11 Extinction and inattention. 0 = no abnormality 1 = visual, tactile, auditory, spatial, or personal inattention or extinction. 2 = profound hemi inattention or hemi inattention to more than one modality.. Total score:

1a. Level of Consciousness: the investigator must choose a response, even if a full evaluation is prevented by such obstacles as an endotracheal tube, language barrier, orotracheal trauma/bandages. A 3 is scored only if the patient makes no movement (other than reflexive posturing) in response to noxious stimulation. 1b. LOC Questions: the patient is asked the month and his/her age. The answer must be correct there is no partial credit for being close. Aphasic and stuporous patients who do not comprehend the questions will score 2. Patients unable to speak because of endotracheal intubation, orotracheal trauma, severe dysarthria from any cause, language barrier or any other problem not secondary to aphasia are given a 1. It is important that only the initial answer be graded and that the examiner not "help" the patient with verbal or non verbal cues. 1c. LOC Commands: the patient is asked to open and close the eyes and then to grip and release the non paretic hand. Substitute another one step command if the hands cannot be used. Credit is given if an unequivocal attempt is made but not completed due to weakness. If the patient does not respond to command, the task should be demonstrated to them (pantomime) and score the result (i.e., follows none, one or two commands). Patients with trauma, amputation, or other physical impediments should be given suitable one step commands. Only the first attempt is scored. 2. Gaze: only horizontal eye movements will be tested. Voluntary or reflexive (oculocephalic) eye movements will be scored but caloric testing is not done. If the patient has a conjugate deviation of the eyes that can be overcome by voluntary or reflexive activity, the score will be 1. If a patient has an isolated peripheral nerve paresis (CN III, IV or VI) score a 1. Gaze is testable in all aphasic patients. Patients with ocular trauma, bandages, pre existing blindness or other disorder of visual acuity or fields should be tested with reflexive movements and a choice made by the investigator. Establishing eye contact and then moving about the patient from side to side will occasionally clarify the presence of a partial gaze palsy. 3. Visual: visual fields (upper and lower quadrants) are tested by confrontation, using finger counting or visual threat as appropriate. Patient must be encouraged, but if they look at the side of the moving fingers appropriately, this can be scored as normal. If there is unilateral blindness or enucleation, visual fields in the remaining eye are scored. Score 1 only if a clear cut asymmetry, including quadrantanopia is found. If patient is blind from any cause score 3. Double simultaneous stimulation is performed at this point. If there is extinction patient receives a 1 and the results are used to answer question 11. 4. Facial palsy: ask, or use pantomime to encourage the patient to show teeth or raise eyebrows and close eyes. Score symmetry of grimace in response to noxious stimuli in the poorly responsive or non comprehending patient. If facial trauma/bandages, orotracheal tube, tape or other physical barrier obscures the face, these should be removed to the extent possible. 5 & 6. Motor function arm and Leg: the limb is placed in the appropriate position: extend the arms (palms down) 90 degrees (if sitting) or 45 degrees (if supine) and the leg 30 degrees (always tested supine). Drift is scored if the arm falls before 10 seconds or the leg before 5 seconds. The aphasic patient is encouraged using urgency in the voice and pantomime but not noxious stimulation. Each limb is tested in turn, beginning with the nonparetic arm. Only in the case of amputation or joint fusion at the shoulder or hip may the score be "9" and the examiner must clearly write the explanation for scoring as a "9". 7. Limb Ataxia: this item is aimed at finding evidence of a unilateral cerebellar lesion. Test with eyes open. In case of visual defect, insure testing is done in intact visual field. The finger nose finger and heel shin tests are performed on both sides, and ataxia is scored only if present out of proportion to weakness. Ataxia is absent in the patient who cannot understand or is paralyzed. Only in the case of amputation or joint fusion may the item be scored "9", and the examiner must clearly write the explanation for not scoring. In case of blindness test by touching nose from extended arm position. 8. Sensory: sensation or grimace to pin prick when tested, or withdrawal from noxious stimulus in the obtunded or aphasic patient. Only sensory loss attributed to stroke is scored as abnormal and the examiner should test as many body areas [arms (not hands), legs, trunk, face] as needed to accurately check for hemisensory loss. A score of 2, "severe or total," should only be given when a severe or total loss of sensation can be clearly demonstrated. Stuporous and aphasic patients will therefore probably score 1 or 0. The patient with brain stem stroke who has bilateral loss of sensation is scored 2. If the patient does not respond and is quadriplegic score 2. Patients in coma (item 1a = 3) are arbitrarily given a 2 on this item. 9. Best language: a great deal of information about comprehension will be obtained during the preceding sections of the examination. The patient is asked to describe what is happening in the attached picture, to name the items on the attached naming sheet, and to read from the attached list of sentences. Comprehension is judged from responses here as well as to all of the commands in the preceding general neurological exam. If visual loss interferes with the tests, ask the patient to identify objects placed in the hand, repeat, and produce speech. The intubated patient should be asked to write. The patient in coma (question 1a=3) will arbitrarily score 3 on this item. The examiner must choose a score in the patient with stupor or limited cooperation but a score of 3 should be used only if the patient is mute and follows no one step commands. 10. Dysarthria: if patient is thought to be normal an adequate sample of speech must be obtained by asking patient to read or repeat words from the attached list. If the patient has severe aphasia, the clarity of articulation of spontaneous speech can be rated. Only if the patient is intubated or has other physical barrier to producing speech, may the item be scored "9", and the examiner must clearly write an explanation for not scoring. Do not tell the patient why he/she is being tested. 11. Extinction and inattention (formerly Neglect ): sufficient information to identify neglect may be obtained during the prior testing. If the patient has a severe visual loss preventing visual double simultaneous stimulation, and the cutaneous stimuli are normal, the score is normal. If the patient has aphasia but does appear to attend to both sides, the score is normal. The presence of visual spatial neglect or anosagnosia may also be taken as evidence of abnormality. Since the abnormality is scored only if present, the item is never untestable. SERIOUS ADVERSE EVENTS (SAE) CHECK Did the patient experience a serious adverse event in this episode? Yes (if yes, please complete SAE form on final page)
