will discuss about Neurological Assessment.

-What do u know about Neurological Assessment
-How many cranial Nerves in Nervous system
-Why Neurological assessment is important


Neurological Assessment
A neurological examination is the assessment of sensory neuron
and motor responses, especially reflexes, to determine whether the
nervous system is impaired. This typically includes a physical
examination and a review of the patient's medical history,[1] but
not deeper investigation such as neuroimaging.

Purpose
 Evaluate the function of the nervous system
 Detect nervous system dysfunction
 Monitor response to treatment

Sedation should be stopped or decreased for an accurate
assessment Types of LOC
 Full Consciousness: Alert, awake, responds appropriately
to stimuli, follows commands.
 Confusion: Disoriented, short attention span, agitated,

restless, may have hallucinations.
 Lethargic: Drowsy, delayed response to stimuli, slow in
speech and mental process, & may drift off to sleep during
exam.
 Obtunded: Able to arouse with stimulation very drowsy.
Response is minimally maintained. Indifference to
external stimuli exists.
 Stuporous: Minimal spontaneous movement. Verbal
responses are minimal & incomprehensible. Requires
vigorous stimuli to elicit a response.
 Comatose: Awareness & arousal are absent. No response
to verbal or painful stimuli.

CRANIAL NERVE EXAMINATION
Cranial Nerve Nerve Type Function
Olfactory Nerve
(I)
Olfaction (Sensory) The patient is
exposed to aromatic
substances (e.g.,
coffee) and asked to
identify the odor.
Optic Nerve (II) Vision (Sensory) The patient is asked
to identify
objects/letters from
predefined distances.

Visual field The examiner wags a
finger towards the
patient's visual field
from all sides
Oculomotor nerve
(III), trochlear
nerve (IV),
abducens
nerve(VI)
Eye Movement
(Motor)
Patients are asked to
follow a finger
moving up, down,
laterally, and
diagonally with they
eyes. Observe if
paresis, nystagmus,
or alterations of
smooth pursuit
appear

Visual
accomodation
The physician moves
a finger towards the
patient. If visual
accommodation is
intact, the finger is
clearly visualized by
the patient at all
times.


Eyelid Ptosis The patient is asked
to open and close the
eyes.
Trigeminal Nerve Facial sensation The examiner lightly

9













































(V) touches three distinct
facial areas (the
forehead, cheek, and
jaw). Normally, light
touch should be felt
by the patient in all
three areas. If this is
not the case, tests for
abnormalities of
other sensory
modalities (e.g.,
pain, temperature)
should be performed.
Muscle function
(muscles of
mastication)
The patient is asked
to open and close
his/her mouth; at the
same time, the
examiner palpates
the masseter muscle.

Facial Nerve
(VII)
Motor function
(muscles of
expression)
If motor function is
intact, the patient
should be able to
perform the
following: Forehead
wrinkling Closing
the eyes tightly Nose
wrinkling Inflate the
cheeks Smiling
(showing teeth)
Whistling
Taste If the sense is intact,
the patient should be
able to taste sweet,

Hypoglossal
Nerve (XII)
Tongue muscles
(motor function)
The tongue should
be pressed against
the cheek from the
inside, while the
examiner tests the
strength by pushing
from the outside.
Hypoglossal nerve
paralysis: when the
patients stick out the
tongue, it moves
towards the impaired
side



THE MOTOR SYSTEM EXAMINATION
The motor system evaluation is divided into the following:
body positioning, involuntary movements, muscle tone and
muscle strength.
Upper motor neuron lesions are characterized by weakness,
spasticity, hyperreflexia, primitive reflexes and the Babinski sign.
Primitive reflexes include the grasp, suck and snout reflexes.
Lower motor neuron lesions are characterized by weakness,
hypotonia, hyporeflexia, atrophy and fasciculations.
Examination of Motor System
Aim: To assess the functional status of the motor system of the
given subject. Steps of motor system assessment

motor system
examination

 Bulk of muscle
 Tone of muscle
 Strength of muscle
 Co-ordination of movements
 Gait
 Involuntary movements
Bulk of Muscle:
By just observing the subject, any significant difference in the
bulk of muscle between both sides of the body can be
assessed. A tape is used to measure the circumference of the
limb at the same distance from a nonmovable bony
prominence, on both sides. The size or bulk of voluntary
muscle varies with age, sex, body build, state of nutrition and
muscular exercise.
Abnormalities include:
(a) Atrophy: In atrophy or wasting, the muscle becomes small
in size. This can occur due to disuse, neurological disorders,
joint injury or joint diseases.
(b) Hypertrophy: Here the bulk of the muscle increases eg,
muscular dystrophies. In pseudomuscular dystrophy due to
pathological changes in the muscles, the muscle bulk
increases, but these enlarged muscles are weak inspite of their

14













































size.
Tone of Muscle
The mild degree of tension or partial state of contraction found
in normal healthy muscle is referred to as muscle tone. The
tone is assessed by asking the subject to relax completely and
then passively moving the joints of motor system examination
Listener listen, discuss and clarify the doubts motor system
examination the upper and lower extremities. The resistance
offered by the muscle during passive movement represents the
degree of muscle tone. Abnormalities:
Hypertonia: Increase in muscle tone.
a) Spasticity - Seen in upper motor neuron lesions. The muscle
tone is increased and is of clasp knife’ type. As the joint is
passively flexed or extended, there is increased resistance to
begin with, but as the movement is continued the resistance
suddenly decreases.
b) Rigidity
i) Lead pipe rigidity - Characteristic feature of extrapyramidal
lesions. Resistance is felt uniformly through out the
movement. Here both agonists and antagonists muscles
contract.
ii) Cog-wheel rigidity - Here the agonists and antagonists

15













































muscles contract alternately and regularly during the passive
movement. As there is alternate increase and decrease in
resistance the passive movement will be jerky, like the
movements of a cog wheel. This is seen in extrapyram idal
diseases.
iii) Decorticate and Decerebrate rigidity-In decorticate
position the upper limb is flexed and the lower limb extended -
due to cerebral cortical lesions. In decerebrate rigidity there is
extension of all limbs with internal rotation of the upper limb
and plantar flexion of the feet.
(2) Hypotonia: Decrease in muscle tone. There is decreased
resistance to passive movement there is increased range of
movements in the limbs. This is seen in lower motor neuron
lesion and cerebellar lesions.
Strength of the muscle (Power):
The patient tries to contract the muscle against resistance
offered by the examiner (active method). Assessment:
inspection and palpation of muscle groups
Findings
 Fasciculation: involuntary, asynchronous contraction of
muscle fascicles within a single motor unit; usually
benign but can signify a lower motor neuron lesion

16













































 Tenderness
 Abnormal movements (e.g., tremor, tic, myoclonus)
 Abnormal posture
 Atrophy or hypertrophy (examined bilaterally)
 Muscle groups are measured to compare specific
differences in size.
 In neurologic disorders, the small hand muscles are often
affected by atrophy.
Power (strength) of the Muscles:
Definition: maximal effort a patient is able to exert from an
individual muscle or group of muscles
Assessment The patient is asked to flex and extend
extremities against resistance Muscle power tests should be
performed bilaterally for comparison Muscle power grading
0 = no contraction (paresis)
1 = flicker or trace of contraction
2 = active movement, with gravity eliminated
3 = active movement against gravity
4 = active movement against gravity and resistance
5 = normal power
Muscle Co-ordeination
Definition: ability to coordinate movements

17













































Assessment Finger-to-nose test: A test for appendicular
ataxia in which the examiner holds up a finger and the patient
is asked to touch his or her nose and the examiner's finger as
quickly an alternation as possible. The examiner can move the
finger to accentuate the deficits. Patient's with cerebellar
lesions will exhibit dysmetria and/or overshoot the target.
Heel-knee-shin test: Rapid alternating movement test: A
group of tests for dysdiadochokinesia characterized by
performing rapidly alternating movements. One of these tests
involves asking patients to tap their laps alternately with the
palm and the back of their hand. Deficits in this task suggest a
cerebellar lesion
Findings
 Dysmetria
 Dysdiadochokinesia
 Gait assessment
 Evidence for vestibular disorders, sensory or cerebellar
ataxia (see “Diagnostics” in cerebellar syndromes)
Assessment
Observation of casual gait: The patient is asked to walk a few
steps forwards and backwards.
Normal gait: steady, natural arm swing

18













































Abnormal gait: broad-based or unsteady gait, short-stepping
gait Balance test: The patient is asked to place one foot
directly in front of the other as if walking on a tightrope
Foot drop test: The patient is asked to walk on their heels
(impossible in the case of deep fibular nerve lesions)
Walking on tiptoes (impossible in the case of tibial nerve
lesions) Romberg test
Test for assessing ataxia (vestibular, sensory, or cerebellar
ataxia) May help to distinguish between sensory and
cerebellar ataxia.
The patient is asked to stand with both feet together, raise the
arms, and close the eyes.
Positive Romberg: closing the eyes impairs coordination
(patient starts swaying, or swaying increases), which is
indicative of sensory ataxia.
Negative Romberg
Closing the eyes does not affect patient's balance (patient's
swaying does not increase).
Uncontrollable swaying, even with eyes open, is indicative of
cerebellar ataxia.
An increased tendency to fall sideways after closing the eyes
indicates a vestibular disorder.

assessment





Trendelenburg sign
Tests for neurological insufficiency of the gluteus medius and
gluteus minimus muscles, which are innervated by the
superior gluteal nerve The patient is asked to stand on one leg.
Physiological: when standing on one leg, the pelvis remains
level (no compensatory movements of the upper body) →
Negative Trendelenburg sign
Pathological: pelvic drop towards the unimpaired,
unsupported side → Positive Trendelenburg sign

REFLEX ASSESSMENT
Tendon Reflex
Definition: stretch, monosynaptic reflexes
Assessment
During reflex testing, the patient should be relaxed (at least
the muscles involved in the reflex test should be relaxed). (→
also see: radiculopathy)
Elderly patients may have reduced or absent lower deep
tendon reflexes due to normal aging-related changes in
muscles and tendon
Biceps reflex
First, the examiner places his/her thumb on the patient's

biceps tendon, then the examiner strikes his/her thumb with a
reflex hammer and observes the patient's forearm movement.
Triceps reflex
The examiner holds the patient's arm (forearm hanging
loosely at a right angle) and taps the triceps tendon with a
reflex hammer to induce an extension in the elbow joint.
Knee reflex
Striking the tendon just below the patella (leg is slightly bent)
induces knee extension.
Ankle reflex
Striking the Achilles tendon with a reflex hammer elicits a
jerking of the foot towards its plantar surface. Alternatively,
the reflex is triggered by tapping the ball of a foot from the
plantar side. Adductor reflex
 Tapping the tendon above the medial condyle of femur
elicits the adductor reflex.
 Superficial reflexes
 Definition: polysynaptic reflexes elicited by
stimulation of the skin
 Superficial reflexes are divided into two subgroups:
 Physiological reflexes
 Pathological superficial reflexes: in case of central

Abdominal reflex
 Abdominal reflexes are tested with the patient lying
down. The anterior abdominal wall is lightly stroked
with a spatula from lateral to medial (bilaterally) in
following areas:
 below the coastal arch
 around the umbilicus
 above the inguinal ligament
 A normal response is a contraction of the abdominal
muscles, while the absence of contractions is indicative
of nerve root damage.
Anal reflex
Stroking the skin around the anus with a spatula elicits the
anal reflex, which results in a contraction of the anal
sphincter muscles. Cremasteric reflex
The reflex is elicited by stroking the medial, inner part of the
thigh. A normal response is a contraction of the cremaster
muscle that pulls up the testis on the same side of the body.
Primitive reflexes

infants, but not in adults, where they may appear in case of
diffuse brain injury due to lack of common inhibiting factors
Sucking reflex
Stroking the mouth induces sucking activity.
Palmar grasp reflex
Stroking the palms elicits finger flexion.
Palmomental reflex
Stroking the ipsilateral thenar eminence from proximal to
distal induces a short involuntary contraction of the mentalis
muscle.

SIGNS OF MENIGEAL OR NERVE ROOT
IRRITATION
Definition: triad of nuchal rigidity , headache, and
photophobia, associated with irritation of the inflamed
meninges and/or spinal nerves
Examination: The examiner passively flexes the neck of the
patient lying in the supine position.
Causes: subarachnoid hemorrhage (SAH), bacterial
meningitis, etc. Kernig sign: in a supine patient, painful
passive extension of the knee when the thigh is flexed at the
hip (knee at a 90° angle) Brudzinski sign: Involuntary lifting

associated with tension of the irritated meninges and,
especially, the lumbosacral spinal nerves during neck flexion

SENSORY ASSESSMENT
Light touch
Dorsal columns
To test for symmetry of touch sensation, the examiner
touches the patient's body at different locations bilaterally.
In cases of suspected radicular lesions, the particular
dermatome should be examined individually.
In cases of suspected peripheral nerve lesions, diagnostics
should involve checking the areas innervated by the
corresponding sensory nerves.

To
Summarize
Implements such as a broken spatula can be used to test pain
sensation bilaterally (e.g., by gently prodding the patient with
the object). Temperature sensation is tested using two objects
of different temperatures (e.g., two test tubes with cold and
warm water).
Finding
Decreased (hypoalgesia) or increased (hyperalgesia)
sensitivity to nociceptive stimuli Proprioception (joint
position)
Dorsal columns
To test proprioception, the most distal joint of the big toe or
the distal interphalangeal joint of the thumb are held by its
sides and moved up and down.
The patient should be able to identify the positional change
with eyes closed.
Finding:
Abnormalities of proprioception suggest and peripheral
polyneuropathy or myelopathy.
