THE NEUROLOGICAL EXAMINATION
NEUROLOGICAL EXAM
• Mental status
• Cranial nerves
• Motor exam
– Strength
– Gait
– Cerebellar
• Reflexes
• Sensation
MENTAL STATUS
“FOGS”
 Family story of memory loss
 Orientation
 General Information
 Spelling &/or numbers
 Recognition of objects
Level of Consciousness
• Awake and alert
• Agitated
• Lethargic
– Arousable with
• Voice
• Gentle stimulation
• Painful/vigorous stimulation
• Comatose
LANGUAGE
• Fluency
• Naming
• Repetition
• Reading
• Writing
• Comprehension
Aphasia vs. dysarthria
MEMORY
• Immediate
– Really a measure of attention rather than memory
• Remote
• 3 objects at 0/3/5 minutes
• Historical events
• Personal events
Orientation
• Person
– Not who they are but who you are
• Place
• Time
OTHER COGNITIVE FUNCTIONS
• Calculation
• Abstraction
• Similarities/differences
• Judgement
• Personality/behavior
CRANIAL NERVE EXAM
• I - olfactory
– Don’t use a noxious stimulus
– Coffee, lemon extract
• Ii - optic
– Visual acuity
– Visual fields
– Fundoscopic exam
CRANIAL NERVE EXAM
• Iii/iv/vi oculomotor, trochlear, abducens
– Pupillary response
– Eye movements
• 9 cardinal positions
– Observe lids for ptosis
• V - trigeminal
– Motor - jaw strength
– Sensory - all 3 divisions
– A lesion that effects C5 will usually effect all three segments
(ophthalmic, maxillary, & mandibular) so the exam light
touch on both cheeks. By cotton.
CRANIAL NERVES
• Vii - facial
– Observe for facial asymmetry
– Forehead wrinkling, eyelid closure, whistle/pucker
– Bell’s Palsy- Where the nerve is injured between pons &
face there is total facial paralysis i.e., weakness of a
corner of the mouth + closing the eye + wrinkling the
brow.
• Viii - vestibular
– Acuity
– Rinne, weber
– Rubbing your fingers together next to the patients ear.
CRANIAL NERVES
• Ix/x - glossopharyngeal, vagus
– GAG reflex check
• Xi - spinal accessory
– Sternocleidomastoid m.
– Trapezius muscle
• Xii - hypoglossal
– Tongue strength
– Right xii thrusts tongue to left
– stick out your tongue
– The tongue will deviate to the side of weakness.
MOTOR EXAMINATION
STRENGTH
• Strength
– Graded 0 - 5
– 0 - no movement
– 1 - flicker
– 2 - movement with gravity removed
– 3 - movement against gravity
– 4 - movement against resistance
– 5 - normal strength
STRENGTH EXAM
• Upper and lower extremities
• Distal and proximal muscles
• Grip strength is a poor screening tool for strength
• Subtle weakness
– Toe walk, heel walk
– Out of chair
– Deep knee bend
Motor exam, cont
• Subtle signs of weakness on a cortical/subcortical
basis
– Pronator drift
– Orbiting
Gait evaluation
• Include walking and turning
• Examples of abnormal gait
– High steppage
– Waddling
– Hemiparetic
– Shuffling
– Turns en bloc
MUSCLE OBSERVATION
• ATROPHY
• FASCIULATIONS
ABNORMAL MOVEMENTS
• TREMOR
– REST
– WITH ARMS OUTSTRETCHED
– INTENTION
• CHOREA
• ATHETOSIS
• ABNORMAL POSTURES
CEREBELLAR FUNCTION
• RAPID ALTERNATING MOVEMENTS
• FINGER TO FINGER TO NOSE TESTING
• HEEL TO SHIN
• GAIT
– TANDEM
Romberg Test
• Key test:
• Be sure to check orthostatic (B/P) for changes first
• Balance is maintained by vision, vestibular sense &
proprioception. These feed into the cerebellum either
directly or indirectly. If a patient sways with eyes open or
close it is considered +.
Coordination
• Key Test:
• Finger to nose & heel to shin motions
• Alternating rapid movements of hand & foot.
Examples of tapping thumb & index fingers
together, or heel on floor & tap toes on floor.
• Balance test- Tandem gait or Romberg test.
REFLEXES
MUSCLE STRETCH REFLEXES (DEEP
TENDON REFLEXES)
• GRADED 0 - 5
– 0 - ABSENT
– 1 - PRESENT WITH REINFORCEMENT
– 2 - NORMAL
– 3 - ENHANCED
– 4 - UNSUSTAINED CLONUS
– 5 - SUSTAINED CLONUS
MSR / DTR
• BICEPS
• BRACHIORADIALIS
• TRICEPS
• KNEE
• ANKLE
Reflexes
• Key tests:
• Triceps, biceps, knee jerk, Achilles & Babinski are the major
reflexes.
• Asymmetry is usually a sign of major pathology.
• Babinski- This points to a upper motor neuron lesion. A
positive test is when the lateral aspect of the foot is
scratched & the big toe dorsiflexes & the other toes fan out
OTHER REFLEXES
• Upper motor neuron dysfunction
– BABINSKI
• present or absent
• toes downgoing/ flexor plantar response
– HOFMAN’S
– JAW JERK
• Frontal release signs
– GRASP
– SNOUT
– SUCK
– PALMOMENTAL
TONE
• INCREASED, DECREASED, NORMAL
• COGWHEELING
• CLASP KNIFE
SENSORY EXAM
SENSORY EXAM
• Vibration
– 128 hz tuning fork
• Joint position sense
• Pin prick
• Temperature
Start distally and move proximally
HIGHER CORTICAL SENSATIONS
• GRAPHESTHESIA
• STEREOGNOSIS
• DOUBLE SIMULTANEOUS STIMULATION
• BAROSTHESIA
• TEXTURES
Sensory Extremity Examination
• Key Test:
• Pain Sensation- Use simultaneous stimulation
(sharp, dull, etc.)
• Proprioception- Test big toe (position).
MS, neurosyphilis, & pernicious anemia may cause
loss of lower extremity proprioception.
