3. Overview Organize your thinking into six categories: Mental Status 意識狀態 Cranial Nerves 顱神經檢查 Motor Exam 運動功能檢查 Reflexes 反射 Coordination and Gait 協調性及步態 Sensory Exam 感覺功能檢查

4. Awareness Patient Examine for Cortical Deficits Orientation: time, place, person and situation) Digital span: 7 numbers foreward and 5 numbers backward Confusion of right and left Calculation: 100－7－7…or 20－3－3… Recent memory: recall 3 objects after 5-minutes interval

17. IX –Glossopharyngeal舌咽神經X –Vagus迷走神經 Listen to the patient's voice, is it hoarse or nasal? Ask Patient to Swallow Ask Patient to Say "Ah" Test Gag Reflex (Unconscious/Uncooperative Patient)

18. XI – Accessory 副神經 From behind, look for atrophy or assymetry of the trapezius muscles. Ask patient to shrug shoulders against resistance. Ask patient to turn their head against resistance. Watch and palpate the sternomastoid muscle on the opposite side.

19. XII – Hypoglossal 舌下神經 Listen to the articulation of the patient's words. Observe the tongue as it lies in the mouth

20. Cranial Nerves Observation Ptosis (III) Facial Droop or Asymmetry (VII) Hoarse Voice (X) Articulation of Words (V, VII, X, XII) Abnormal Eye Position (III, IV, VI) Abnormal or Asymmetrical Pupils (II, III)

22. Rapid Alternating Movements

23. Point-to-Point Movements

24. Motor Power Pronator Drift

25. Muscle System Strength Muscle Groups 0/5: no contraction 1/5: flicker 2/5: movement when gravity eliminated 3/5: movement against gravity 4/5: movement against resistance 5/5: normal strength

26. Reflexes 反射 Deep Tendon Reflexes 0: absent reflex 1+: trace, or seen only with reinforcement 2+: normal 3+: brisk 4+: nonsustainedclonus (i.e., repetitive vibratory movements) 5+: sustained clonus Jendrassik's maneuver (locking the finger tips together and pulling) Anal reflex: rectal sphincter tone, spinal cord injury
