Answer 12

pinprick
temperature
touch pressure

Question 13

biggest reason for sensation evaluation?

Answer 13

SAFETY

Question 14

what is densitization used for?

Answer 14

used for hypersensitivity

- increased use of textures, weight bearing, mirror visual feedback

Question 15

what is discriminative sensory reeducation used for?

Answer 15

protective sensation is intact but you are not able to localize
- interventions include grading objects from grossly dissimilar to more similar objects

Question 16

what two things does discriminative sensory reeducation

Answer 16

localization

graded discrimination

Question 17

def of passive sensory training:

Answer 17

cortical reorganization in response to repetitive stimulation
- extensive repetitive stim applied to impaired site and patient does not participate

Question 18

difference between passive and active sensory training:

Answer 18

passive does NOT involve patient

active DOES involve patient

Question 19

how predictable are sensory losses in CVA vs. TBI:

Answer 19

TBI = not predictable 
CVA = 60% of stroke in carotid artery system have sensory deficits

Question 20

what does sensory loss in the CVA depend on?

Answer 20

disruption of blood flow: where the blood hit and how much
