Chapter 1: Overview
Introduction
The SENSUS®Pain Management System is an innovative
wearable medical technology that provides relief from chronic
pain. It consists of a device and an electrode that attaches to the
device. The device is worn on your upper calf, a few inches below
the knee, and is controlled by a single button.
SENSUS provides pain relief by comfortably stimulating the
nerves that carry normal, non-painful sensations to your brain.
Electrical stimulation of these nerves is believed to change the
levels of certain natural chemicals in your nervous system that
decrease your pain.
Pain relief is initiated by simply pressing a button on the device.
Each therapy session is 60 minutes. After your rst session,
therapy will automatically restart every other hour. Pain relief
usually begins within 15 minutes of the start of a therapy session
and may last up to an hour following the end of a session. You
have complete control and can start or end therapy anytime.
You should review this User Manual carefully. Chapter 2 shows
you how to get started. Chapters 3–5 provide detailed instruc-
tions on device use. Chapter 6 describes device use during sleep.
Chapter 7 offers tips for taking care of the electrodes. Chapter
8 provides information on preventing skin irritation, particularly
if you have sensitive or dry skin. Appendix C gives answers to
frequently asked questions.
If you have any questions about how to use SENSUS please call
NeuroMetrix customer service at [phone].
