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, but not deeper investigation such as neuroimaging.

Medical Technology Tackles New Health Care Demand - Research Report - March 2...pchutichetpong
M Capital Group (“MCG”) predicts that with, against, despite, and even without the global pandemic, the medical technology (MedTech) industry shows signs of continuous healthy growth, driven by smaller, faster, and cheaper devices, growing demand for home-based applications, technological innovation, strategic acquisitions, investments, and SPAC listings. MCG predicts that this should reflects itself in annual growth of over 6%, well beyond 2028.
According to Chris Mouchabhani, Managing Partner at M Capital Group, “Despite all economic scenarios that one may consider, beyond overall economic shocks, medical technology should remain one of the most promising and robust sectors over the short to medium term and well beyond 2028.”
There is a movement towards home-based care for the elderly, next generation scanning and MRI devices, wearable technology, artificial intelligence incorporation, and online connectivity. Experts also see a focus on predictive, preventive, personalized, participatory, and precision medicine, with rising levels of integration of home care and technological innovation.
The average cost of treatment has been rising across the board, creating additional financial burdens to governments, healthcare providers and insurance companies. According to MCG, cost-per-inpatient-stay in the United States alone rose on average annually by over 13% between 2014 to 2021, leading MedTech to focus research efforts on optimized medical equipment at lower price points, whilst emphasizing portability and ease of use. Namely, 46% of the 1,008 medical technology companies in the 2021 MedTech Innovator (“MTI”) database are focusing on prevention, wellness, detection, or diagnosis, signaling a clear push for preventive care to also tackle costs.
In addition, there has also been a lasting impact on consumer and medical demand for home care, supported by the pandemic. Lockdowns, closure of care facilities, and healthcare systems subjected to capacity pressure, accelerated demand away from traditional inpatient care. Now, outpatient care solutions are driving industry production, with nearly 70% of recent diagnostics start-up companies producing products in areas such as ambulatory clinics, at-home care, and self-administered diagnostics.
Defecation
Normal defecation begins with movement in the left colon, moving stool toward the anus. When stool reaches the rectum, the distention causes relaxation of the internal sphincter and an awareness of the need to defecate. At the time of defecation, the external sphincter relaxes, and abdominal muscles contract, increasing intrarectal pressure and forcing the stool out
The Valsalva maneuver exerts pressure to expel faeces through a voluntary contraction of the abdominal muscles while maintaining forced expiration against a closed airway. Patients with cardiovascular disease, glaucoma, increased intracranial pressure, or a new surgical wound are at greater risk for cardiac dysrhythmias and elevated blood pressure with the Valsalva maneuver and need to avoid straining to pass the stool.
Normal defecation is painless, resulting in passage of soft, formed stool
CONSTIPATION
Constipation is a symptom, not a disease. Improper diet, reduced fluid intake, lack of exercise, and certain medications can cause constipation. For example, patients receiving opiates for pain after surgery often require a stool softener or laxative to prevent constipation. The signs of constipation include infrequent bowel movements (less than every 3 days), difficulty passing stools, excessive straining, inability to defecate at will, and hard feaces
IMPACTION
Fecal impaction results from unrelieved constipation. It is a collection of hardened feces wedged in the rectum that a person cannot expel. In cases of severe impaction the mass extends up into the sigmoid colon.
DIARRHEA
Diarrhea is an increase in the number of stools and the passage of liquid, unformed feces. It is associated with disorders affecting digestion, absorption, and secretion in the GI tract. Intestinal contents pass through the small and large intestine too quickly to allow for the usual absorption of fluid and nutrients. Irritation within the colon results in increased mucus secretion. As a result, feces become watery, and the patient is unable to control the urge to defecate. Normally an anal bag is safe and effective in long-term treatment of patients with fecal incontinence at home, in hospice, or in the hospital. Fecal incontinence is expensive and a potentially dangerous condition in terms of contamination and risk of skin ulceration
HEMORRHOIDS
Hemorrhoids are dilated, engorged veins in the lining of the rectum. They are either external or internal.
FLATULENCE
As gas accumulates in the lumen of the intestines, the bowel wall stretches and distends (flatulence). It is a common cause of abdominal fullness, pain, and cramping. Normally intestinal gas escapes through the mouth (belching) or the anus (passing of flatus)
FECAL INCONTINENCE
Fecal incontinence is the inability to control passage of feces and gas from the anus. Incontinence harms a patient’s body image

3. The neuro assessment is a key component in the
care of the neurological patient. It helps to:-
Detect the presence of neurological disease or
injury and monitor its progression.
Determine the type of care you'll provide , and
patient's response to your interventions.
4. The initial assessment should cover several
critical areas:
level of consciousness
cranial nerves
Movement
sensation
cerebellar function
and reflexes.
This initial exam will establish
baseline data with which to compare
subsequent assessment findings.
5. DEFINITION :-
Neurological examination is a method of obtaining specific data in
relation to the function of a patient's nervous system.
INDICATIONS :-
Neurological observations are required :-
to monitor and evaluate changes in the nervous system by indicating
trends.
To aid in diagnosis and treatment which in turn may affect prognosis
and rehabilitation
The frequency of neurological observations will depend on the
patient’s condition and the rapidity with which changes are occurring
or expected to occur.
6. Evaluation of level of consciousness (LOC) are the
most important parts of the neuro exam. A change is
usually the first clue to a deteriorating condition.
The following terms are commonly used :
Full consciousness:- The patient is alert, attentive, and
follows commands. If asleep, she responds promptly to
external stimulation and, once awake, remains
attentive.
Lethargy:- The patient is drowsy but awakens—
although not fully—to stimulation. She will answer
questions and follow commands, but will do so slowly
and inattentively.
7. Obtundation:- The patient is difficult to arouse and
needs constant stimulation in order to follow a simple
command. She may respond verbally with one or two
words, but will drift back to sleep between stimulation.
Stupor:- The patient arouses to vigorous and
continuous stimulation; typically, a painful stimulus is
required. She may moan briefly but does not follow
commands. Her only response may be an attempt to
withdraw from or remove the painful stimulus.
Coma: - The patient does not respond to continuous or
painful stimulation. She does not move—except,
possibly, reflexively—and does not make any verbal
sounds.
8. A fully conscious patient will respond to questions
quickly and is alert to events occurring around him.
As his condition deteriorates he may display
irritability, lack of concentration and uncooperative
behavior.
A comatose state is one in which the patient fails to
respond to verbal and painful stimuli. Fever and pain
commonly cause confusion, disorientation and
irritability.
To prevent the patient from falling, stand by the side of
the patient during the test.
The patient's cultural and educational background
influences his ability to answer test questions.

as an alert patient sitting in a chair, would be scored
a 4.
•If the patient is asleep or lying with eyes closed, but
opens them upon command, a 3 is awarded.
•If the patient only opens their eyes to painful
stimulus, such as running the tip of blunt scissors
along the bottom of the foot, or a pinch, the patient is
scored a 2.

conversation would be given a 5 on the GCS.
•A patient who makes appropriate conversation but is
confused, such as an Alzheimer's patient, would be
scored as a 4.
•The patient who makes inappropriate conversation, such
as answering a question on an entirely different subject,
would be given a 3.
• If the patient cannot make conversation, but instead has
very garbled speech or makes incomprehensible sounds,
they would be given a 2.
•The patient who is unable to speak or make any sounds
for any reason, such as being on a ventilator with a
breathing tube in their mouth, would be given a 1.
19. III MOTOR RESPONSE: (6)
•A patient who moves arms and legs either spontaneously or
on command is given a 6.
• If the patient displays purposeful movement with a painful
or unpleasant stimulus, such as trying to push it away, the
patient is given a 5.
•The patient who only withdraws away from pain with no
other response is given a 4.
•A score of 3 is given to the patient demonstrating decorticate
posturing, in which the patient's extremities are drawn
inward toward the center of the body.
•If the patient is in the decerebrate posture, the extremities
are turned away from the body, and the score is 2.
•The lack of any movement or posturing is given a 1.
21. Assess patient's immediate recall by asking the patient to
repeat a sequence of numbers.
Assess patient's recent memory by asking him to give
details of the recent events like what he had in breakfast
etc.
Assess patient's past memory by:
Requesting him/her to re-call previous medical history, family
events e.g. birth days. instructions given earlier in the
assessment.

Inspect all major groups bilaterally for symmetry,
hypertrophy & atrophy
Muscle Strength:
Assess the power in major muscle groups against resistance
on a 5 point scale in all four extremities, comparing one side
with the other
5/5= Normal full strength. Muscle moves actively through the
full range of motion against the effects of gravity & applied
resistance

against the effect of gravity with weakness to applied
resistance
3/5=Muscle moves actively against the effects of gravity alone
34. 2/5= Muscle moves across a surface but cannot overcome
gravity
1/5= Muscle contraction is palpable & visible
0/5= Muscle contraction or movement is u8ndetectable
Muscle Tone:
Assess the muscle tone while moving each extremity
through its range of passive motion. When tone is
decreased, the muscles are soft, flabby or flaccid
When tone is increased, the muscles are resistant to
movement, rigid, or spastic
Muscle co-ordination:
Ask client to touch each finger to the thumb quickly in
succession
Ask the client to pat the thighs first with palms, then with
back of the hands & to repeat patting quickly
35. Gait & station:
•Ask the client to stand still, walk & walk with one foot in front
of the other on a straight line
•Ask the client to stand quietly with feet together
36.
37. REFLEXES
Two types of reflexes are normally present:
1. Superficial or coetaneous reflexes
2. Deep Tendon reflex
1. Superficial Reflexes: Elicited by the stimulation of the skin or
mucous membranes. The stimulus is produced by stroking a
sensory zone with an object that will not cause damage
a. Abdominal Reflex: lightly stroking the skin on an abdominal
quadrant normally contracts the abdominal muscle, moving
the umbilicus towards the stimulated side.
b. Plantar Reflex: Scratching the foot’s outer aspect of the plantar
surface (outer sole) from the heel toward the toes normally
contracts or flexes the toes in clients older than 2 yrs of age.
38. c. Corneal reflex: Gently touching cornea with a wisp of cotton
causes reflex blinking
d. Pharyngeal (Gag) Reflex: Gentle stimulation with a tongue blade
at the back of the throat and pharynx normally produces gagging
39. 2. Deep tendon Reflex: Elicited by sharply striking a muscle’s
tendon’s point of insertion with a sudden, brief blow of a
reflex hammer
Reflex Assessment Technique Expected Response
Biceps Reflex A blow on the
examiner’s thumb
placed over the biceps
tendon
