THE NEUROLOGICAL EXAM: A CONCISE VERSION

 

 

TABLE 1. AN OUTLINE OF THE

NEUROLOGICAL EXAMINATION


 

General Exam:

Neurological Exam:

     Mental Status Testing

     Cranial Nerves

     Motor Function

     Reflexes

     Sensation

     Coordination

     Gait

 

Aspects of the General Exam

Measure pulse and blood pressure, supine and standing

Neck: listen for bruits; define range of movements; palpate for tenderness

Head; note tilt or turn; measure circumference (infants); note symmetry; palpate for tenderness and masses, listen for bruits

Back: note spinal curvatures; palpate and percuss for tenderness; determine mobility

 

Mental Status Testing

Determine level of education; present and previous employment

Alertness and attention

Orientation

Language

Memory: short-term, long-term, and fund of general knowledge

Calculations

Spatial perception

Reasoning

 

Cranial Nerves

CN I   Smell coffee or vanilla

CN II 

Visual acuity

Visual fields

Optic fundi

CN III, CN IV, CN VI

Range of movement and alignment of the visual axes

Fixation, saccades, smooth-pursuit, vestibulo-ocular reflex, vergence

Pupils

Lids

CN V

Sensory testing of all 3 divisions

Corneal reflex

Muscles of mastication

Jaw jerk

CN VII 

Facial symmetry and strength

Taste over anterior 2/3 tongue

CN VIII

Sensory threshold (compared with examiner)

Air conduction vs. bone conduction

Weber lateralization test

Vestibulo-ocular reflex

Vestibulospinal tests

CN IX, CN X

Phonation and enunciation

Symmetry of palate elevation

Gag reflex

CN XI

Sternomastoid and trapezius muscles: bulk and strength

CN XII

Tongue bulk, strength, adventitious movements
 

Motor Function

Pronator drift

Forearm-rolling test

Bulk

Tone

Power

Adventitious and abnormal movements

 

Reflexes

Muscle Stretch Reflexes

Upper limbs: Biceps, triceps, supinator, finger jerks

Lower limbs: Patellar, ankle jerks

0 = absent

1+ = hypoactive

2+ = normal

3+ = hyperactive

4+ = hyperactive with clonus

 

Plantar responses (Babinski)

Also test Hoffmann's sign, grasp, snout, and palmomental reflexes.

 

Sensation

Elementary Modalities:

Pain

Light touch

Vibration

Joint position sense

Thermal Sense

Discriminative Modalities:

Two point discrimination

Stereognosis

Graphesthesia

Baresthesia

Double simultaneous stimulation

 

Coordination

    Finger to nose

    Heel to shin

    Rapid alternating movements

    Finger and foot tapping

 

Gait

   Stance

  Arm swing

  Size of stride

  Turning

  Stability

  Tandem gait

  Heel and toe walking
