                NEUROLOGICAL ASSESSMENT
INTRODUCTION
Nurses in many practice settings encounter patient with altered neurologic
functions. Disorders of nervous system can occur at any time during the life span
and can vary from mild, self limiting symptoms to devastating, life threatening
disorders. A nurse must be skilled in the general assessment of the neurologic
function and be able to focus on specific areas as needed. Assessment requires
knowledge of anatomy and physiology of the nervous system and the
understanding of the array of test and procedures used to diagnose neurological
disorders. Knowledge about the nursing implications and interventions related to
assessment and diagnostic testing is also essential.
DEFINITION
A neurological examination is the assessment of sensory neurons and motor
responses, specially reflexes to determine whether the nervous system is
impaired.
INDICATIONS
     To monitor and evaluate changes in the nervous system.
     To diagnose and manage client care.
COMPONENTS OF NEUROLOGICAL ASSESSMENT
     A comprehensive health history.
     Neurologic physical examination.
HEALTH HISTORY
       An important aspect of neurological assessment is the health history of the
patient. This initial interview provide an excellent opportunity to systematically
explore the patient’s current condition and relate events while simultaneously
observe overall appearance, mental status, posture, movement and affect. Health
history consist of biographic data, history of present illness, past health history,
family history and psychosocial history.
1. BIOGRPHICAL DATA:
   It includes the following details:
       a. Personal profile.
       b. Source of history.
       c. Patient’s mental status
2. HISTORY OF PRESENT ILLNESS
    a. Chief complaints: Neurological disorder may be stable or progressive,
       characterized by symptom free periods as well as fluctuations in
       symptoms. The health history therefore includes details about the onset,
       characteristics, severity, location duration and frequency of symptoms
       and signs; associated complaints; precipitating, aggravating and
       relieving factors; progression remission and exacerbation; the presence
       or absence of similar symptoms among family members.
    b. Symptom assessment: The nurse should collect history relevant to
       neurological disorders:
          Headache: Any unusual frequent or severe headaches?
          Head injury: Ever had any head injury? If yes, any treatment
            taken?
          Dizziness/Vertigo: Ever feel lightheaded, like feeling faint?
          Seizures: Ever had any convulsions? If yes, its details.
          Visual disturbances: Any problems with eye sight? If yes, its
            details.
          Abnormal sensations: any tingling or loss of sensation? If yes. Its
            details.
          Tremors: Any shakes or tremors in the hands or face?
          Weakness: Any weakness or problem moving any body part? Is
            this generalized or local? Does it occur with anything?
3. PAST HEALTH HISTORY
   Childhood history: Child hood infectious disease and immunization status,
    birth, motor and mental mile stones disease related to neurological
    sequlae (rubella, cytomegalo virus infection, herpes simplex, influenza,
    meningitis etc.). Also enquire about complications of pregnancy, labor and
    delivery, birth trauma, birth weight, postnatal illness, convulsions with
    fever, learning ability, school performance.
   Major illness and hospitalization: enquire about the history of diseases
    like diabetes mellitus, hypertension, cancer, epilepsy etc. Also enquire
    about injury, hospitalization or surgery related to nervous system
    problems.
   Medication history: Enquire about the use of medication by the patient
    including details about over the counter medication and herbal
    medications. Collects details on medication like anticoagulants, CNS
    stimulants and CNS depressants.
   Allergies and Adverse Drug Reactions: Should include both type of agent
    and reaction, 26 severity, and whether dose dependent.
4. FAMILY HISTORY
     There is no such thing as a non contributory family history. Report
     presence or absence of neurologic diseases or family risk factors for
     neurologic diseases (e.g. migraine, epilepsy, cerebrovascular disorders,
     myopathy, cerebellar diseases). Ages and causes of death of first degree
     relatives may be relevant, especially in age related diseases (e.g. cancer,
     DM, HTN, cardiovascular disorders).
5. PSYCO-SOCIAL HISTORY
     Should include details of marital status, maximum education level
     achieved, occupational history, hobbies and avocations, previous
     residencies, etc.
6. PERSONAL HISTORY
     Personal habits like use of alcohol, tobacco, recreational drugs, coffee, tea,
     soft drinks and similar substances. Include details of dietary habits, bowel
     and bladder.
GENERAL EXAMINATION
   Vital Signs: Blood pressure, heart rate, respiratory rate, and temperature.
   General Appearance: General observations such as whether well
    nourished, well developed, in distress or not, appearance for stated age.
   General head to toe examination: examine the head, neck and spine using
    inspection, palpation, percussion and auscultation.
        Inspection: Inspect the head for size, shape contour and symmetry.
           Note any ecchymosis around the eyes or behind the ears. Anterior
           basilar skull fracture often result in raccoon eyes, with periorbital
           ecchymosis and drainage of CSF from nares. Middle fossa basilar
           skull fracture often result in ecchymosis over the mastoid process
           behind the ear (battle’s sign) and drainage of blood, CSF or both
           from ears.
        Palpation: Palpate the skull lightly for nodules or masses and to
           supplement inspection findings. The skull usually feels smooth and
           firm, areas of bogginess or depression are abnormal. Palpation of
           neck muscles may identify masses or tender areas. Ask the client to
             flex the neck with chin touching the chest, look for nuchal rigidity,
             which is a manifestation of meningeal irritation.
           Percussion: Gentle percussion over the spinous process may
             produce pain or tenderness, which are abnormal findings.
           Auscultation: Auscultation of the major neck and other vessels may
             reveal bruits or other sounds suggesting abnormality. Use the bell of
             the stethoscope to auscultate carotid arteries, bruits result from
             turbulent flow suggestive of atherosclerosis.
      Respiratory System: Auscultate for clearness, crackles, wheezes, and
       report if increased respiratory effort.
      Cardiovascular system: Auscultate the carotids, heart, palpate peripheral
       pulses, choosing which one or multiple would be most relevant to the case.
      Gastro intestinal system: Examine softness, tenderness, distension, bowel
       sounds, and/or masses.
      Extremities: Check for cyanosis, edema, and palpate pulses.
NEUROLOGICAL EXAMIATION
The neurologic examination is a systematic process that includes a
variety of clinical test, observations and assessments designed to
evaluate the neurologic status of a complex system.
The major components of a neurological examination are as follows:
      Mental status examination
      Cranial nerve function
      Sensory nerve function
      Motor nerve function
      Reflex testing
      Co-ordination
      Gait
The equipment needed are:
      Reflex hammer
      Tuning forks
      A Snellen’s chart or pocket vision card
      Pen torch
      Wooden handled cotton swabs
      Paper clips
MENTAL STATUS EXAMINATION
    The components of mental status examination include the following:
   General appearance and behaviour:
        Level of consciousness, motor activity, body posture, dress hygiene,
        facial expression, speech pattern
      GLASGOW COMA SCALE: To assess the level of consciousness in a
      patient
      It is the first assessment if vital signs are normal to identify for changes
      when there’s neurologic injury. The summation of the individual score (i.e.
      E + V + M) classifies the person into stages of consciousness i.e. mild
      (score = 13–15), moderate (score = 9–12), severe (score = 3–8), and
      vegetative state (score <3).
      The GCS measures the following functions:
       Eye Opening (E)
          o 4 = spontaneous
          o 3 = to sound
          o 2 = to pressure
          o 1 = none
       Verbal Response (V)
          o 5 = orientated
          o 4 = confused
          o 3 = words, but not coherent
          o 2 = sounds, but no words
          o 1 = none
       Motor Response (M)
          o 6 = obeys command
          o 5 = localizing
          o 4 = normal flexion
          o 3 = abnormal flexion
          o 2 = extension
          o 1 = none
      TERMS USEDTO DESCRIBE CONSCIOUSNESS
       Alert: patient responds immediately to minimal external stimuli.
       Confused: It’s a profound deficit that includes disorientation,
        bewilderment, and difficulty in following commands.
       Delirious: Patient is disoriented to time, place, and person with loss of
        contact with reality and often has auditory or visual hallucination.
       Lethargic: The patient is sleepy and drowsy and will awaken and
        respond appropriately to command.
       Obtunded: Patient displays dull indifference to external stimuli,
        response is minimally maintained. Questions are answered with a
        minimal response.
       Stupor: the patient becomesunconscious spontaneously and is very
        hard to awaken.
       Semi coma: The patient is not will respond purposefully to deep pain.
       Coma: the patient is completely unresponsive.
 Orientation:
     There are three general elements to orientation: person, place, and time.
     Orientation to person is simply the ability to identify one's name and is
       the last element of orientation to be lost
     Orientation to place is the ability to name where they are, or at least
       what building, city, or state they are in.
     Time includes the date (allow a day or two error for inpatients who are
       frequently somewhat disoriented), day of week, year, and season.
      It's a good idea to preface your inquiry with a general comment about the
      fact you ask every patient these questions (otherwise patients will often
      take offense at your asking them their name or where they are).
 Memory:
     In memory we check for recent, immediate and remote memory.
      Recent memory: Ask to recall the diet of the previous 24 hours and such
        other information that are easily verifiable. Usually impaired in organic
        brain syndrome and Alzheimer’s disease.
      Immediate memory: Ask the client to repeat the words you say
        immediately.
      Remote memory: Ask patient about memories from past e.g. childhood
        school, anniversary etc. Impaired in cortical injury and Alzheimer’s.
 Judgement:
     Refers most commonly to an assessment of the patient's ability to avoid
  behaviour that might be harmful to themselves or others. For example: "If you
  found a driver's license on the ground, what would you do?
 Insight:
     Insight is a patient's awareness of themselves and their condition.
 Attention span:
     Patient should be able to focus on examiner’s questions and respond. It’s
  usually impaired in fatigue, anxiety and intoxication.
 Mood/affect:
     Mood is what the patient reports to you. Affect is what you observe.
 Intellectual performance:
     It consist of knowledge and calculation ability. Ask client to
  identify commonly known people, places and current events. Assess
  calculation ability by asking to perform simple addition and subtraction.
 Thought content:
     Thought content includes assessment for the presence of a number of
  important psychiatric signs or symptoms, including:
      Hallucinations: These come in several flavours. Auditory
        hallucinations can be voices (very common in schizophrenia) or
        recurrent sounds (such as of helicopters, artillery common in combat
        veterans suffering posttraumatic stress disorder). Visual
        hallucinations often imply an organic etiology (such as delirium,
        withdrawal, or some central nervous system lesion), but can be seen in
        schizophrenia and other psychiatric states. Visual hallucinations of
        deceased love ones are common in grieving. Other types of
        hallucinations include tactile, olfactory, or gustatory.
      Delusions: Fixed, false, idiosyncratic beliefs. Common delusions are
        grandiose and persecutory.
 Perception:
     Perception involves the organisation, identification and interpretation of
  sensory information to understand the world around us.
      Agnosia: It is the inability to interpret or recognise objects seen through
        the special senses. The patient may see a pencil but do not know what
        it is or what to do with it. The patient may even be able to describe it
        but is not able to interpret its function.
      Apraxia: Its another perceptual problem. It involves the inability to
        perform skilled, purposeful movements in the absence of motor,
        sensory or coordination losses
 Language ability:
     Communication is one of the cortical function of the body. A person with
  normal neurological function can understand and communicate in spoken and
  written language. A deficiency in language function is called aphasia.
CRANIAL NERVE FUNCTION
   1. CRANIAL NERVE 1 (Olfactory): Sense of smell
             Formal assessment of ability to smell is generally omitted, unless
      there is a specific complaint. If further needed then first check to make sure
      that the patient is able to inhale and exhale through the open nostril.
         Tell the patient to close his eyes. Present a distinct, common odour
  (e.g. lemon, coffee) to the open nostrils. The patient should be able to
  correctly identify the odour at approximately 10 cm distance.
2. CRANIAL NERVE II (Optic):Sensation of vision
   Visual acuity:
       Hold Snellen chart at comfortable reading distance. Cover one eye
       and have patient read chart. For each eye, record smallest line patient
       can read.
       Interpretation: If the patient can read line 8, their vision is 20/20,
                        which means that the patient can see the same line
                        of letters at 20 feet that a person with normal vision
                        can see at 20 feet.
   Visual fields:
        Stand directly in front of patient and have patient look you in both
    eyes. Ask the patient to cover his left eye with his left hand and then
    cover your right eye with your right hand. Ask patient to indicate on
    which side the finger is moving.
3. CRANIAL NERVE III, IV&VI (Oculomotor, Trochlear and Abducent):
   eye movement and pupillary reflexes
   Pupillary light reflex:
        Ask the patient to look at a distant target and fix to that target. Shine
    a pen torch into each eye in turn, bringing the beam in quickly from the
    lateral side to centre. Note the pupil response it should constrict and
    bilateral same response is expected.
   Visual inspection:
       o Look at ocular alignment at rest. Stand 3-6 feet in front of patient.
          Ask patient to follow your finger with the eyes without moving
          the head.
       o Move your finger in the six cardinal directions of gaze and
          observe whether movements are full in each eye or at deviation.
       o Move your finger towards bridge of patient’s nose and observe
          eye movements, whether the eye balls moving in one direction or
          not.
4. CRANIAL NERVE V (Trigeminal): facial sensation, motor function and
   corneal reflex
    Facial sensation:
       Ask the patient to close both the eyes. Use sharp end of a cotton
     swab to test sensation on forehead, cheek, and jaw of each side of face.
     Repeat other side of face too.
    Motor function:
        It is checked by the muscles of mastication. Ask the patient to clench
     his teeth tight and palpate for the contraction in the temporalis muscle
     and masseter muscle. Ask the patient to open his mouth, move his jaw
     from side to side, then close his mouth.
    Corneal reflex:
        Testing of the corneal reflex should not be performed unless sensory
     impairment suspected, as it is uncomfortable to the patient. Lightly
     touch peripheral aspect of cornea from the side with fine wisp of cotton.
     Look for normal blink reaction of both eyes. Repeat on other side. If
     response is less than brisk, touch cornea more centrally.
5. CRANIAL NERVE VII (Facial): Facial movement
      Observe for any facial abnormality during conversation like facial
  asymmetry, drooping, sagging or smoothing of normal facial creases. Ask
  patient to do the following activities and note any difference, weakness on
  both the sides of face. Observe for asymmetry while doing the following
  activity:
      Smile
      Puff out cheeks with air.
      Close both lips tightly and resist your attempt to open them.
      Close both eyes and the patient should resist your attempt to open
       them.
      Raise both eyebrows simultaneously.
6. CRANIAL NERVE VIII (Acoustic): hearing
   TESTING OF AUDITORY FUNCTION
      Test the hearing by occluding one ear and whispering two words and
  have the patient repeat them back. Repeat this for the other ear. If patient
  is not able to hear further assessment should be done by ENT specialist to
  rule out pathological condition,
   TO DEMONSTRATE PRESENCE OF CONDUCION DEFECTS
    i.    Watch test: Ability to listen to ticking of wrist watch.
   ii.    Rinnes test: A vibrating tuning fork is placed over mastoid process
          till the sound is heard. Then held in front of one ear at a distance of
          25 cm, care being taken that it does not touch the ear and the other
          ear is plugged. In a normal person sound will be continued to be
          heard. Test is repeated on the other side. In partial deafness hearing
          time is reduced. In total deafness no sound is heard.
   iii.   Weber test: Having identified the presence of conduction deafness,
          localization of the deafness is confirmed by this test. A vibrating
          tuning fork is placed over the midline of the head. Examinee is asked
          to say the side to which sound is heard well. That points out the
          affected side. In conduction deafness affected ear has bone
          conduction better than air conduction.
7. CRANIAL NERVE IX & X (Glossopharyngeal & Vagus): palate
   movement/gag reflex
     Tell the patient to open his mouth and project his tongue outside, and
  say “AHHA”. As patient say “ahha” the uvula will move up. This infers
  that the cranial nerve IX is intact.
      Ask the patient to swallow and note any difficulty doing so. Observe
  the quality and sound of the patient’s voice. Is it hoarse or not? If the patient
  can swallow with ease and has no hoarseness while talking, this infers that
  the cranial nerve X is intact.
     Perform gag reflex test by touching the pharynx with the tongue
  depressor on both the left and then on the right side, observing the normal
  gag or cough.
8. CRANIAL NERVE XI (Spinal Accessory): Turning head against
   resistance
     Have the patient move head from side to side and up and down and
  shrug shoulders against resistance.
9. CRANIAL NERVE XII (Hypoglossal): tongue position and movement
       o Note tongue position at rest in the mouth.
       o Ask to stick out tongue and move it from side to side. Observe
         strength and rapidity of movements.
            o Let the patient push tongue into each cheek while you push from
              the outside. Note strength.
SENSORY FUNCTION ASSESSMENT
Sensory assessment evaluates bilateral pathways of primary sensations. It mostly
focuses on pain, temperature (hot and cold), proprioception (i.e. position sense)
and light touch.
COMPONENTS OF SENSORY ASSESSMENT:
    Sensory testing of the face is done by cranial nerves testing.
    Sensory testing of the extremities focuses on the two main afferent
     pathways:
        o Spinothalamics (detect pain, temperature and crude touch).
        o Dorsal Columns (detect position, vibratory sensation and light
          touch)
      Spinothalamics :
                o Ask the patient to close his eyes so that he is not able to get
                  any visual clue regarding articles used to test his sensation.
                o Touch the patient’s upper limb and lower limb by a needle
                  prick or with cotton wisp or brush and ask patient to
                  differentiate between pain and light touch sensation.
                o Touch one body part followed by the corresponding body
                  part on the other side (e.g., the right upper arm with the left
                  upper arm) with the same instrument. In this way the patient
                  the patient is able to compare the sensations and note any
                  asymmetry if present.
      Dorsal Columns:
          PROPRIOCEPTION: (This refers to the body’s ability to know
           where it is in space or position check.)
                Tell the patient to close his eyes so that he is not able to get
                any visual clue. With one hand, hold either side of great toe at
                the interphalangeal (IP) joint. Place your another hand on the
                lateral and medial aspects of the great toe slightly distal to the
                IP. Bend the toe upwards and downward while informing him
                of which direction you’re moving it. Alternately bend the toe
                 up or down without telling the patient in which direction you
                 are moving it. They should be able to correctly identify the
                 movement and direction.
          VIBRATORY SENSATION: it is done by vibrating a low frequency
           turning fork.
                   The handle of the vibrating fork is places against a boy
                   prominence, the patient is asked if he or she feels a sensation
                   and is instructed to signal the examiner when the sensation
                   ceases.
                   The common used to test for vibratory sense include the distal
                   joint of the great toe and the proximal thumb joint. If the
                   patient does not perceive the vibrations at the distal bony
                   prominence, the examiner progress upward with the tuning for
                   until the patient perceives the vibrations.
MOTOR FUNCTION ASSESSMENT
Motor assessment observes muscle tone, muscle bulk, strength, and abnormal
movements.
Components of motor function assessment: visual inspection, muscle tone,
muscle strength.
VISUAL INSPECTION: MUSCLE BULK AND APPEARANCE
Examine the major muscle groups of the upper and lower extremities. Fully
expose the muscles of both extremities (for comparison). The largest and most
powerful groups are: biceps, triceps, quadriceps, deltoids, and hamstrings.
Muscle groups should appear symmetrically developed when compared with their
counterparts on the other side of the body. There should be no muscle movement
when the limb is at rest.
MUSCLE TONE: MUSCLE TENSION AT REST
Before initiating assessment of muscle tone tell the patient to relax himself and
the joints that is to be examined. Carefully move the limb thoroughly to its normal
full range of motion. Each joint to be done separately.
Note: Normal muscle generates some resistance to movement when a limb is
moved passively by an examiner.
MUSCLE STRENGTH: AGAINST RESISTANCE AND GRAVITY
Test each body part separately to compare muscle strength.
 Intrinsic muscles of the hand:
       Instruct the patient to spread their fingers apart from each other while
  applying resistance (abduction). Then squeeze them all together, with your
  fingers placed in between each of their fingers (adduction).
 Flexors of the fingers:
       Instruct the patient squeezing their hand around two of your fingers and
  make a tight fist. If the grip is normal, you will not be able to pull your fingers
  out of the grip.
 Wrist flexion:
        Have the patient try to flex their wrist forward as you provide resistance.
 Wrist extension:
       Have the patient try to extend their wrist outward as you provide resistance.
 Elbow Flexion:
       First keep the hand parallel to the body and then tell the patient bend hid
  elbow to ninety degrees while keeping palm directed upwards. Then direct him
  to flex his forearm while you provide resistance on the wrist site.
 Elbow Extension:
       The main extensor of the forearm is the triceps muscle. Tell the patient
  extend his elbow against resistance while the arm is held out (abducted at the
  shoulder) from the body at ninety degrees.
 Shoulder Adduction:
       Tell the patient flex at the elbow while the arm is held out from the body
  at forty-five degrees. Then provide resistance as he try to further adduct at the
  shoulder.
 Shoulder Abduction:
       Tell the patient to flex the elbow while the arms is held out from the body
  at forty-five degrees in sitting position. Then provide resistance on the hand as
  he try to further abduct at the shoulder.
 Hip Flexion:
       Tell the patient to be seated, keep your hand on top of one thigh and instruct
  the patient to lift the leg up from the table.
 Hip Extension:
       Tell the patient lying down in prone position, instruct the patient to lift his
  leg off the table against resistance placed by you on the leg.
 Hip Abduction:
       Place your hands on the outer side of either thigh and direct the patient to
  separate their legs against resistance
 Hip Adduction:
      Place your hands on the inner aspects of the thighs and ask them to close
  their legs against resistance.
 Knee Extension:
      Have the seated patient steadily. Keep hand on lower extremity and tell the
  patient to raise against resistance.
 Knee flexion:
      Have the patient rest in prone position. Then tell the patient to lift his heel
  up and off the table against resistance provided by you.
 Ankle Dorsiflexion:
      Direct the patient to lift his toes upwards while you provide resistance with
  your hand.
 Ankle Plantar Flexion:
      Tell the patient to keep foot on your hand and try to flex downwards while
  providing resistance with your hand.
REFLEX TESTING
Reflex testing helps to assess functions of both sensory and motor pathways. It
gives important insights into the integrity of the nervous system at many different
levels.
Achilles reflex testing:
Make the patient to be seated, feet dangling over the edge of the exam table.
Identify the Achilles tendon back of the leg which is cord-like structure running
from the heel to the muscles of the calf. Support the bottom of the foot with your
hand and form a right angle. Strike the tendon directly with reflex hammer. A
normal reflex will cause the foot to plantar flex (i.e. move into your supporting
hand).
Patellar reflex testing:
Make the patient to be seated, feet dangling over the edge of the exam table or
provide supine position. Identify the patellar tendon in front of the knee joint, a
thick, broad band of tissue extending down from the lower aspect of the patella.
For the supine patient, support the back of thigh with your hands such that the
knee is flexed. Strike the tendon directly with reflex hammer. In the normal reflex,
the lower leg will extend towards knee.
Biceps reflex testing:
Make the patient to be seated and relaxed. By flexing at the elbow, identify the
location of the biceps tendon. Patient’s hand can be positioned in two ways, one
by supporting his hand and another by not supporting his hands. Allow the arm
to rest in the patient’s lap, forming an angle of slightly more than 90 degrees at
the elbow.
If you are supporting the patient’s arm, place your thumb on the tendon such that
your thumb is resting directly over the biceps tendon (hold their right arm with
your right; and vice versa) and strike on your finger. If the arm is not supported
by your hand then place your index or middle fingers firmly against the bicep
tendon and strike them directly with the hammer. Normally the biceps will
contract, drawing the lower arm upward directions.
Triceps reflex testing:
Make the patient to be seated and relaxed. On the back of the upper arm, identify
the triceps tendon. Positioning of the patient’s hand can be done in two ways.
Tell the patient to pull the arm out from the patient’s body, such that it roughly
forms a right angle at the shoulder and allow the lower arm dangle directly
downward at the elbow. In other way tell the patient place his hand on his hips.
Strike directly on triceps with hammer. The normal reflex leads to extension at
the elbow and swing away from the body. If the patient’s hands are on his hips,
the arm will not move but the muscle should shorten vigorously.
Babinski Response:
To check Babinski response use the handle point end of reflex hammer. The
patient may be either in siting or supine position. Apply gentle, steady pressure
with the end of the hammer from lateral aspect of the foot towards the heel. When
you reach the ball of the foot, move medially, stroking across this area. In the
normal patient, the first movement of the great toe should be downwards (i.e.
plantar flexion), then the great toe will dorsiflex and the remainder of the other
toes will fan out.
GRADING OF REFLEXES
      0 No evidence of contraction
      1+ Decreased, but still present (hypo-reflexic)
       2+ Normal
      3+ Super-normal (hyper-reflexic)
      4+ Clonus: Repetitive shortening of the muscle after a single stimulation
COORDINATION TESTING:
Finger to nose testing:
      In sitting position of the patient, position your index finger in front of the
patient. Instruct the patient to move his index finger between your finger and his
nose. Reposition your finger after each touch. Then test with the other hand.
      Interpretation: The patient should be able to do this in a steady rate of
speed, properly trace a straight path, and able to touch the end points accurately.
Rapid Alternating Finger Movements:
      Ask the patient to touch the tips of each finger to the thumb of the same
hand. Test both hands.
      Interpretation: The movement should be accurate following sequentially
each fingers.
Rapid Alternating Hand Movements:
      Direct the patient to touch first the palm and then the dorsal side of one
hand repeatedly against their thigh. Then test the other hand.
      Interpretation: The movement should be performed in a steady rate of
speed and accurately.
Heel to Shin Testing:
      In lying down or siting position tell the patient to move the heel of one foot
up and down along the top of the other shin. Then repeat the test in other foot.
       Interpretation: While the patient moves he should trace a straight line
along the top of the shin and be done with reasonable speed.
GAIT TESTING
       The normal gait is effortless, with arms swinging easily at the sides. Look
for disturbances of posture, balance, loss of arm movement, or abnormal leg
movements. Lack of balance and a wide based gait would suggest a cerebellar
disorder.
Romberg test:
      This is a test of balance. Ask the patient to stand. Have the patient stand in
one place with feet together with open eye. Later on tell the patient stand with
closed eyes. It is scored by counting the seconds the patient is able to stand with
eyes closed.
      Interpretation: The Romberg test is positive when the patient is unable to
maintain balance with their eyes closed. Loss of balance suggests impaired
proprioception. If the client cannot maintain balance with the eyes shut, client
may have sensory ataxia (lack of coordination of the voluntary muscles). If
balance cannot be maintained whether the eyes are open or shut, client may have
cerebellar ataxia.
Heel to Toe Walking (Tandem gait test of balance):
       Ask the patient to walk in a straight line in straight position, putting the
heel of one foot directly in front of the toe of the other and continue in same way.
This assessment is performed first with eyes open and then with eyes closed. Then
ask the patient to walk on only toe and then only heal.
       Interpretation: Uncoordinated movement due to a muscle control
       problem that causes an inability to coordinate movements. It leads to a
       jerky, unsteady, to-and-fro motion of the middle of the body (trunk) and
       an unsteady gait (walking style)
       Patients will spread their legs apart to widen the base of support, may
       stagger when they walk (severe cases), and falls toward one or both sides
       while performing heel-toe walk
       Causes:
                 Lesions of the vermis (midline lesions of the cerebellum)
                        Unilateral lesion: sways/falls to one side (the side of
                          the lesion)
                        Bilateral: may sway/fall to either side
                 Loss of position sense
                 Intoxication
CLINICAL EVIDENCE
    Clinical neurology: why this still matters in the 21st century.
            This is a study conducted by David J Nicholl and Jason P Appleton
            to assess the importance of neurological examination in clinical
            setting.
      Abstract: This review argues that even with the tremendous advances in
      diagnostic neuroimaging that the clinical skills involved in clinical
      neurology (ie, history, examination, localisation and differential diagnosis)
      remain key. Yet a number of recent audits suggest that large numbers of
      patients are failing to be assessed properly with a risk of patient harm,
      costly, unnecessary or inappropriate investigations, or delayed diagnosis.
      They reviewed some of the reasons why patients are not being assessed
      properly neurologically, in part as many doctors have limited neurological
      exposure and are hence neurophobic. They proposed that a solution to these
      issues centres around ensuring that a core set of basic neurological skills is
      taught at an undergraduate level, whereas higher level skills, such as the
      use of heuristics, are taught at postgraduate level.
      Conclusion: History and examination are still and will continue to be
      cornerstones of clinical medicine, yet several studies suggest that
      physicians underestimate the impact of examination findings when
      estimating condition probabilities. While the clinician has a medley of
      investigative tools available to them, they should be used appropriately to
      aid the diagnostic process. Even in the modern era, there needs to be a
      wider dissemination to non-neurologists of the essential neurological skills
      they need to have for good quality patient care—national neurological
      associations should lead on this and provide guidance on acceptable, yet
      realistic, skill sets.
    Prevalence of major neurological disorders in predominantly rural
     northwest India
      Abstract: Epidemiological studies based on hospital population,
      geographic isolates, smaller population, and focused groups provide
      valuable information on the pattern of diseases, but do not reflect on the
      true prevalence rates or the changing trends of disease over a period of time
      in different communities. The present study was undertaken to determine
      the prevalence and pattern of various neurological disorders in Himachal
      Pradesh.
      Results:     A total of 260 (out of 10,000 studied) individuals were found
      positive for neurological disorders yielding a crude prevalence of 2.6%.
      The crude prevalence for rural areas was found to be 2.28% (206/9000),
      whereas the crude prevalence in urban area was found to be 5.4%
      (54/1000). Migraine was the most common disorder.
      Conclusion :       In view of the high crude prevalence of major
      neurological disorders, there is a need to develop capacity among
      healthcare professionals regarding them.
CONCLUSION
Practicing neurological assessment stepwise will help us to pertain all the data of
the patient and help to correlate the data for diagnosing the condition of the
patient. Once the abnormalities are identified as a nurse it helps us to plan of the
care. Integrating the neurological health history and physical exam takes practice.
Critically analyse all the data obtained and synthesize the data.
