What Is It?
● Hypersensitivity to specific stimuli (touch, pressure, temperature, etc…) due to abnormal
pain processing
● Treatment technique to decrease how sensitive an area is to a particular stimulus. This
will enable the body’s response to a stimulus to be normalized.

What Causes A Nerve To Be Sensitized?
● Diabetes
● Complex Regional Pain Syndrome
● Injury to Brain, Spine, or Nerves
● Heavy Alcohol Intake
● Post-Surgery
● Peripheral Nerve Disorders
● Fibromyalgia
How Long Does It Take For A Nerve To Be Desensitized?
● Several Days to Several Weeks (Depends on how hypersensitive the nerve is initially)
Mechanism
● Consistent stimulus to the affected area of the body for short durations, frequently
throughout the day to increase sensory input to the brain
● With time, the body will acclimate to the sensation, leading to a decrease in the body’s
pain response to the stimulus
● The body will get used to the stimulus and no longer produce a pain response or become
hypersensitive to the particular stimulus
Application
● Finding stimuli that are “unpleasant” to the hypersensitive area with routinely exposure.
These stimuli may include: hot/cold, various textures, tapping, deep pressure, light touch,
vibration, different fabrics, etc…
● Starting with a stimuli that is least painful and progress toward a stimuli that is most
painful
● Progression of stimulus examples: Use softer material and progress toward rougher
materials; light touch and progress toward deep touch, mild vibration and progress
toward deep vibration, etc…
● Examples of stimuli: brush, towel, ice cubes, warm wash clothes, velcro, toothbrush,
erasers, gloves, kleenex, tennis ball, silk, paint brush, wool, shaving cream, oil, cotton
balls, q-tips, sponge, leather, rubber, etc…
At Home Desensitization Instructions
● Use 5 different stimuli and desensitize for 8-10 minutes, 6-10 times per day.
● Start with the most tolerable stimuli and progress toward the least tolerable stimuli
● Move the texture against your skin (keeping your eyes open): light stroking/firm stroking
in all directions and circular motions
● Concentrate on how it feels and describe out loud what you are feeling
● At the end of the 10 minutes, have someone test you with the stimuli with your eyes
closed, guessing which stimuli is being used
● REPEAT DAILY. CHANGE THE STIMULI BEING USED DAILY.
