Sensory deprivation

Sensory stimulation is a technique that provides meaningful and common smells, movements, feels, sights, sounds, and tastes through the stimulation of all senses.
Sensory deprivation or perceptual isolation is the deliberate reduction or removal of stimuli from one or more of the senses.

4. ervuos.iveor INTRODUCTION
Sensory stimulation is a technique that provides
meaningful and common smells, movements,
feels, sights, sounds, and tastes through the
stimulation of all senses. There are many benefits
to providing sensory stimulation such as increased
communication, environmental awareness,
relaxation, cognitive stimulation.

5. roumplnTYrTouPnIYuiYIveor NORMAL SENSORY PERCEPTION
Sensory Perception involves the conscious
organization and translation of the data or
stimuli into meaningful information. Sensory
perception depends on the sensory receptors,
reticular activating system (RAS),and
functioning nervous pathways to the brain.
The RAS influences awareness of stimuli,
which are received through the, Five senses:
Sight,hearing,touch,Smell, and taste.

6. THE NERVE
A nerve is an organ
containing a bundle
of nerve cells called
neurons.
Neurons carry
electrical messages
called impulses
throughout the
body.

8. TYrTouPnsYIueCpveor SENSORY DEPRIVATION
Sensory deprivation can be thought of as the
opposite of sensory overload . Sensory
deprivation generally means a lessening or
lack of meaningful sensory stimuli,
monotonous sensory input or an interference
with the processing of information.

9. FACTORS AFFECTING SENSATION
PERCEPTION
Developmental:
Vision in new born develops during the first year.
Visual acuity decreases after the age of 60 years.
Hearing is most acute at 10 years of age.
By the age of 65 years, about 55 % has some
hearing loss.
There is decline in smell after the age of 70 years.

10. Social:
People with sensory problems will have less social
interactions. A deaf person will have less social
interaction and verbal communication, sensory
impaired children will have low self-esteem and
less communication.
Occupational:
Type of occupation and occupational environment
affect the sensory perception. People who are
exposed to loud noise for a prolonged period may
develop hearing problems.

11. Pathologic:
Clients with DM may experience an alteration in
Vision.
The presence of visual,auditory,olfactory, gustatory
sensory deficits may cause a decrease in sensory
stimuli.
Therapeutic:
Excessive environmental stimuli in ICU
Restricted visiting hours in ICU
Endotracheal intubation.
Pharmacologic: Aminoglycoside antibiotics and
Sedatives.

Visual deprivation Auditory deprivationTactile deprivation

13. Visual deprivation: The very fast change in the
ocular dominance of the cells. It occurs due to the
changes of the efficacy of synapses from the closed
eye.
Auditory deprivation: Refers to the lack of adequate
hearing stimulation. with auditory deprivation, brain
gradually losses some of its information processing
ability. Ability of auditory system to process speech
declines, due to lack of stimulation.
Tactile deprivation: Deprivation in coma /
immobilisation , a long term care, poorly responsive
patient will be confined to bed being turned every
2hrs,occasionally being ambulated.

14. CLIENTS AT RISK FOR SENSORY
DEPRIVATION
Have impaired vision or hearing
Unable to process stimuli
Have emotional disorders
Limited social contact with family and friends.

15. YAAYivTnnoAnnTYrTouPnnsYIueCpveor EFFECTS OF SENSORY DEPRIVATION
Cognitive
Reduced capacity to learn
Inability to think or solve problem
Poor task performance
Disorientation
Regression
Affective
Restlessness
Increased anxiety
Panic

16. Perceptual
Visual/motor coordination
Color perception
Time judgement

17. Y vupTYrTouPnnIYuiYIveornMYTIO EXTRASENSORY PERCEPTION (ESP)
 ESP is most commonly called the sixth sense. It
is sensory information that an individual receives
which comes beyond the ordinary five senses.
It provide the individual with information of the
present, past and future; as it seems to originate
in a second or alternate reality.
It is the branch of parapsychology.

20. NEUROLOGICAL ASSESSMENT

21. ASSESSMENT OF SENSORY FUNCTION
VISION: Presence of visual problems including
decreased acuity, blurred vision, double vision,
photosensitivity,difficulty seeing near or far. Family
history of visual problem
AUDITORY: Presence of hearing problems, recent
changes in hearing ability, ability to distinguish sounds,
presence of buzzing or ringing noises, use of hearing
aid.
 Touch: Assess whether the client can distinguish
objects in the hand with eyes closed.
Assess the client for sensitivity to light touch and
temperature.

22. Smell: Have the client close his eyes and identify
several Nonirritating odors.
 Position: Perform conventional tests for balance and
position sense.

Sensory perceptual alteration r/t an unfamiliar environment
and an insufficient amount of meaningful stimuli
Visual stimulation
Pictures flowers greeting cards in the room
Wearing sunglasses before going outside
Client with reduced visual acuity may need corrective lenses
Use pocket magnifiers
Auditory stimulation
Call the person by his or her name
Reorient the patient
Speak slowly,clearly,maintain eye to eye contact
Procedure explanations
Allow time for the client to express himself/herself
Use sensory aids.

25. Gustatory and olfactory stimulation
Attention to the oral hygiene and properly fitting dentures
Serve fresh food.
Smell food before eating.
Removal of unpleasant odour from the environment.
Tactile stimulation
Provide touch therapy
Hair brushing , combing , a back rub, and touching of the
arms or shoulders are ways of increasing tactile
stimulation.
Minimize irritating stimuli.

26. Risk for injury related to sensory dysfunction
Careful ambulation of a visually impaired client.
Articles should be within reach and orient location.
 Make sure that the call bell is functioning.
Provide safety devices- side rails, night light, call system.
Impaired skin integrity related to prolonged
immobilization
Change the position of the patient every 2 hourly.
Provide 4 hourly back care.
 Perform physical therapy.
Check the vitals 2-4 hourly.
