Sensation Flashcards
sensory functions
Vision, hearing, smell and taste, touch, pain, proprioception, vestibular functioning
How to assess sensory function
- observation during functional tasks
- Hands on assessment (sensory kit)
- Interview questions
purpose of sensory evaluation
assess extent of sensory loss,
document sensory loss,
identify lesion location,
determine functional impairment and limitations,
Provide direction of treatment and interventions,
(person as a map= where they do and don’t have sensation)
deficits may present safety risks
Special senses
Olfaction, vision, gustation, audition/balance/equilibrium
Somatosensory (most basic sensory info)
Primary somatosensory= receptive, to receive input from the outside world
Cortical= perceptual/perception, to figure out what is going on
Cranial nerves
CN 1- olfactory
CN 2- Vision
CN 3- oculomotor- muscles of eye
CN 4- Trochlear- superior oblique eye
CN 5- Trigeminal- sensory of face and mouth.
CN 6- Abducens- lateral rectus eye muscles
CN 7- Facial
CN 8- Vestibulocochlear- equilibrium and hearing.
CN 9- Glossopharyngeal- throat for swallowing, posterior 3rd of tongue
CN 10- Vagus- internal organs
CN 11- Accessory- head, neck, shoulders
CN 12- Hypoglossal- tongue
mechanoreceptors
Touch, pressure, stretch, vibration
Chemoreceptors
cell injury or damage
Thermoreceptors
Heating, cooling
assessment planning
If fine touch and proprioception are intact no need to assess temp or pain.
If pain and temperature are absent, no need to assess fine touch or proprioception.
quickly assess areas that should be intact, more thoroughly assess areas likely to be affected.
Desensitization
used for hypersensitivity (usually with nerve trauma cases, burns, amputations, soft tissue injuries)
Passive sensory training
cortical reorganization in response to repetitive stimulation.
You are doing things to the client. not sustainable (you do everything)
Active sensory training
you are having them be part of their treatment plan. more aware of how to monitor themselves.
Active participation of patient, find thumb without looking, identification of shape, weight , and texture
awareness of sensory deficits
Compensatory technique (use vision to compensate for decreased sensation),
Education on risk factors,
Emphasize consistent skin care.
