Cranial Nerve II - Optic Nerve ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Cranial Nerves III, IV and VI ,[object Object],[object Object],[object Object],Testing eye movements Testing pupil accommodation
Normal: ■ Able to read without difficulty ■ Visual acuity intact 20/20, both eyes Hippus phenomenon: Brisk constriction of pupils in reaction to light, followed by dilation and constriction - may be normal or sign of early CN III compression. Abnormal: ■ CN II deficits - can occur with stroke or brain tumor. ■ Changes in pupillary reactions - can signal CN III deficits. ■ Increased ICP causes changes in pupillary reaction As pressure increases, response becomes more sluggish until pupils finally become fixed and dilated.

Examining the Motor System ,[object Object],[object Object],[object Object],[object Object],[object Object]
MUSCLE STRENGTH ,[object Object],[object Object],[object Object],[object Object],[object Object],British Medical Council Method of Scoring
Balance and Coordination ,[object Object],[object Object],[object Object],[object Object]
Balance and Coordiantion a. Rapid Alternating Movements (RAM) Ask the person to pat the knees with both hands, lift up, turn hands over, and pat the knees with the backs of the hands. Then ask to do this faster. ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],The patient is asked to pronate and supinate the hands as rapid as possible
b. Finger-to-Finger test With the persons eyes open, ask that he or she use index finger to touch your finger, then his or her own nose. After a few times move your finger to a different spot. ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Perform Tandem Walking - ask the person to walk a straight line in a heel-to-toe fashion. - This decreases the base of support and will accentuate any problem with coordination. Normal: Person can walk straight & stay balanced ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Hopping in place, alternating knee bends ( some individuals cannot hop owing to aging or obesity)

F. Superficial Reflexes Abdominal Reflex ■ Stroke patient’s abdomen diagonally from upper and lower quadrants toward umbilicus. ■ Contraction of rectus abdominis. Umbilicus moves toward stimulus.
Perianal Reflex ■ Gently stroke skin around anus with gloved finger. Normal: ■ Anus puckers. Cremasteric Reflex ■ Gently stroke inner aspect of a male’s thigh. Normal: ■ Testes rise. Bulbocavernosus Reflex ■ Gently apply pressure over bulbocavernous muscle on dorsal side of penis. Normal: ■ Bulbocavernosus muscle contracts.

Sensory Examination ,[object Object],[object Object],[object Object],[object Object],[object Object]
Stereognosis With patient’s eyes closed, place a familiar object, such as a coin or a button, in patient’s hand, and ask patient to identify it. ■ Test both hands using different objects. ,[object Object],[object Object],Abnormal: ■ Abnormal findings suggest a lesion or other disorder involving sensory cortex or a disorder affecting posterior column.
Sensory Extinction ■ Simultaneously touch both sides of patient’s body at same point. ■ Ask patient to point to where she or he was touched. ,[object Object],[object Object],[object Object],[object Object]

  • 32. Normal: ■ Able to read without difficulty ■ Visual acuity intact 20/20, both eyes Hippus phenomenon: Brisk constriction of pupils in reaction to light, followed by dilation and constriction - may be normal or sign of early CN III compression. Abnormal: ■ CN II deficits - can occur with stroke or brain tumor. ■ Changes in pupillary reactions - can signal CN III deficits. ■ Increased ICP causes changes in pupillary reaction As pressure increases, response becomes more sluggish until pupils finally become fixed and dilated.
