Sensation: Study Guide Flashcards
from study guide duh
what are the eight sensory system functions:
sight smell taste hearing vestibular functioning proprioception touch and pain
what are the two types of sensory systems:
special senses and somatosensory
what are somatosensory senses:
the most basic sensory information
what are the two types of somatosensory?
primary
cortical
which somatosensory sense is secondary
cortical
what are the six senses that fall under special senses:
vision
hearing
gustation
audition, balance, equilibrium
what are the cranial nerves for olfaction:
CN1
CN for vision:
CN2
gustation CN:
7 AND 9
facial and glossopharyngeal
audition, balance, and equilibrium?
CN 8
vesibulocohlear
what are three ways to assess sensory function?
proprioception
stereognosis
point localization
what are three threshold tests?
pinprick
temperature
touch pressure
biggest reason for sensation evaluation?
SAFETY
what is densitization used for?
used for hypersensitivity
- increased use of textures, weight bearing, mirror visual feedback
what is discriminative sensory reeducation used for?
protective sensation is intact but you are not able to localize
- interventions include grading objects from grossly dissimilar to more similar objects
what two things does discriminative sensory reeducation
localization
graded discrimination
def of passive sensory training:
cortical reorganization in response to repetitive stimulation
- extensive repetitive stim applied to impaired site and patient does not participate
difference between passive and active sensory training:
passive does NOT involve patient
active DOES involve patient
how predictable are sensory losses in CVA vs. TBI:
TBI = not predictable CVA = 60% of stroke in carotid artery system have sensory deficits
what does sensory loss in the CVA depend on?
disruption of blood flow: where the blood hit and how much
