OTD 341 Nolte Ch. 12 Part II CN Possible Lesion Symptoms Test III Lateral strabismus (deviation of eye out due to denervated medial rectus muscle) Eye movements leading to diplopia (double vision) Pupillary responses Difficulty moving eye up and down (can also cause diplopia) Ptosis (drooping of eyelid) Mydriasis (dilated pupil) Lens cannot be focused for near vision tasks IV Strabismus (deviation of eye into extorsion [up & in] due to denervated superior Test simultaneously with oculomotor nerve oblique muscle), which can lead to difficulty walking down steps or reading; diplopia; & corrective head tilt V Sensory: Sensory: Ipsilateral loss of sensation to head, face, and inner oral cavity Sensory testing of head region Trigeminal neuralgia: sudden, excruciating pain in sensory regions of trigeminal Corneal reflex testing nerve caused by compression of trigeminal nerve Motor: Motor: weakness in chewing and jaw deviation to the affected side Jaw strength/observation for asymmetries VI Medial strabismus (deviation of eye in due to denervated lateral rectus muscle) Test simultaneously with oculomotor nerve (look to leading to diplopia (double vision) the side) VII Sensory: decreased taste on anterior tongue Sensory: discriminating tastes (sweet, salty, sour, Motor: bitter, umami) Facial asymmetries Motor: Bell’s palsy (damage to facial nerve [LMN]) Corneal blink reflex Lack of corneal blink reflex Smile, raise eyebrows, pucker, etc. IX Sensory: decreased taste on posterior tongue Sensory: discriminating tastes Motor: Motor: Loss of gag and swallow reflexes Gag reflex Dysphagia (difficulty swallowing) Swallow test (speech therapist or OT) X Visceral: Test with IX (gag reflex and swallow test) Irregular heartbeat Check for hoarseness, volume, and clearness of Difficulty breathing speech Skeletal: Dysphonia (hoarseness) Dysarthria (slurred speech) Dysphagia and loss of gag reflex XI Weakness with laterally flexing and rotating head; and with shrugging shoulders Laterally flex head; rotate head; shrug shoulders XII Atrophy and paralysis of ipsilateral tongue causing deviation of tongue toward side Stick out tongue of lesion/weak side; dysarthria (slurred speech) & dysphagia (difficulty swallowing) 3
