					Assessing Sensory Function
1. Test for superficial pain perception with cotton; if no response, pin prick
2. Test for Thermal Sensation
3. Assess for Tactile Sensation
         a. Ask patient to close the eyes and tell you what is felt when you touch the patient lightly on the hand, wrist, arm,
         thigh, lower legs, and feet
4. Have patient close the eyes and assess for sense of position
         a. Move patient’s toes or fingers up, down, and to the side
         b. Have the patient tell the direction of movement


Assessing Cranial Nerve Function

1. Olfactory nerve (I)
        a. With patient’s eyes closed, have the patient identify common smells, such as coffee, beer and cinnamon
2. Optic Nerve (II)
        a. Examine the patient’s eyes with an opthalmoscopy
        b. Have patient read the Snellen eye chart
3. Oculomotor Nerve (III)
        a. Compare the size and shape of pupils and the equality of pupillary response to a pin light (flashlight) in a
        darkened room
4. Trochlear Nerve (IV) and Abducens Nerve (VI)
        a. Both of these are responsible for lateral eye movement
        b. Ask the patient to follow your finger with his or her eyes, as you slowly move it from the patient’s far right to
        the far left
5. Trigeminal Nerve (V)
        a. To assess facial sensation, use a cotton ball to stroke the patient’s cheek, jaw, and forehead

6. Facial Nerve (VII)
        a. To assess facial motor function ask the patient to raise the eyebrows, wrinkle the forehead, and open the mouth
        b. Facial nerves are also involved in taste so place sugar of salt on tongue
7. Acoustic Nerve (VIII)
        a. Ask the patient to identify common sounds, such as a person whispering or a tapping noise
        b. A tuning fork can be used to test air and bone conduction
8. Glossopharyngeal Nerve (IX)
        a. Use a tongue depressor to test gag reflex

9. Vagus Nerve (X)
        a. The vagus nerve slows the heart rate
        b. It can increase gastrointestinal (GI) peristalsis and controls swallowing
        c. To assess the patient’s ability to swallow, look for symmetric movement of palate when patient says, “Ah.”
10. Spinal Accessory Nerve (XI)
        a. Assess shoulder muscle strength
        b. Ask the patient to shrug shoulder against resistance
11. Hypoglossal Nerve (XII)
        a. Assess tongue movement
        b. Ask the patient to stick out tongue
