A

refers to reception, transmissoin and interpretation of sensory stimuli

2
Q

types of sensation

A
touch (light touch)
deep pressure (poke)
pain
proprioception
thermal sensatoin
taste and smell
3
Q

purpose of sensory testing

A

assess extent of sensory loss and document recovery

determine impairment and functional limitations/training required

4
Q

conditions associated with sensory loss

A
CNS dysfunction
PNS dysfunction
burn
arthritis
SCI
s/p peripheral nerve repair
5
Q

what to do during sensory evaluation

A

stabilize arm
demonstrate test on unaffected area with eyes open
eliminate auditory cues and occlude vision
apply stimuli at irregular intervals
same therapist should administer and re-administer assessment

6
Q

Semmes-Weinstein monofilaments assessment-how many different monofilaments

A

5

7
Q

Semmes-Weinstein monofilaments assessment: green filament

A

normal sensation

8
Q

Semmes-Weinstein monofilaments assessment: blue filament

A

diminished light touch

9
Q

Semmes-Weinstein monofilaments assessment: purple filament

A

diminished protective sensation

10
Q

Semmes-Weinstein monofilaments assessment: red filament

A

loss of protective sensation or loss of all sensation except deep pressure

11
Q

purpose of sensory desensitization

A

help client build tolerance for sensation in a hypersensitive area

12
Q

when to use desensitization

A

pt experiencing hypersensitivity in area that was injured secondary to nerve injury or complex regional pain syndrome

13
Q

equipment used for desensitization

A

different textures

ie. cotton, velvet, flannel, washcloth, light grade sandpaper

14
Q

protocol for desensitization

A

patient rubs the affected area lightly, concentrating on the feel of the texture until the area feels less sensitive
15-20 min 3x/day

15
Q

purpose of sensory reeducaton

A

client learns to interpret pattern of abnormal sensory impulses followed by an injury to a peripheral nerve

16
Q

when to use reeducation

A

client is experiencing loss of sensation

  • focus is usually on fingertips
  • must be in “purple” range on Sammes-Weinstein
17
Q

when to begin early phase of sensory reeducation

A

when client can feel protective sensation
return of touch perception of fingertips
4.31 or lower on Sammes Weinstein

18
Q

early phase sensory reeducation technique

A
  1. client observes therapist administers stimulus with pencil eraser tip (moves tip or holds tip on skin)
  2. repeat with vision occluded; client concentrates on perception, imagining what they just observed in step 1
  3. pt overves while therapist applies stimulus, verbalizing what they are seeing
19
Q

late phase sensory reeducation technique

A

client tries to discriminate between touch of objects of different sizes or textures
