Testing procedure

1. Explain the procedure to the patient with his/her eyes open. For example, “I am going to firmly touch various parts of your arms (or other body part) with this pencil eraser, and when you feel the pressure you say ‘Now.’”
2. Demonstrate the procedure with the patient’s eyes open until the patient understands the procedure to be performed.
3. The patient closes his/her eyes, or vision is otherwise occluded.
4. Firmly touch the applicable body regions with the eraser end of the pencil.
5. Ask the patient to identify when the stimulus is presented without hesitation.
6. Vary the time between stimuli to avoid developing a rhythmic pattern. 
7. Repeat throughout suspected areas.
8. Document findings.
