Sensory Testing - Class 8 Flashcards
why is sensation important
sensory impairment affects motor output
sensory impairments affect the ability to gain new motor skills
motor learning is highly dependent on sensory info and feedback
this will assist in providing the source of motor dysfxn
anesthetic limbs are at risk of injury
sensory impairment affects motor output
this is tested before the motor component
keys to success w/ sensation testing
clear instructions and proper explanation of what you are doing
tell pt not to guess
do not give too much input
perform a trial run
occlude the pts vision
perform a trial run
often in a region that is not impaired
pt will get a sense of normal
how are sensory receptors divided
superficial sensation
deep sensation
combined cortical sensations
superficial sensation is responsible for
superficial sensation
info from the external environment
perception of pain, temp, light touch and pressure
superficial sensation tests
pain
temp
light touch
pressure
pain –> superficial sensation tests
use a sharp object that does not pierce the skin
should be cleaned before hand
ask when the pt verbally feels the stimulus
temp –> superficial sensation tests
test
2 test tubes of different color
if too cold or too hot, it may cause pain
pt indicated if they feel cold or hot
2 test tubes of different color –> temp –> superficial sensation tests
cold (41-50 F)
heat (104-113 F)
light touch –> superficial sensation tests
test
use a piece of a cotton to the area to be tested
response
w/ eyes closed, pt indicated when they are being touched
pressure –> superficial sensation tests
PT presses down until there is an indent into the pt’s skin
pt tells PT when they feel that they are being touched
deep sensation is tested
2nd
deep sensation is responsible for
deep sensation
receive stimuli from the muscles, tendons, ligs, joints and fascia
position sense
awareness of joints at rest
movement awareness (kinesthesia)
vibration
deep sensational testing
kinesthesia
proprioception
vibration
