INTRODUCTION
This booklet was written for people who are considering or have received a Nevro®
Senza® Spinal Cord Stimulator (SCS) system to help treat pain. Every person is unique
and your medical needs differ from those of others, even people with the same
condition and the same SCS system. For this reason, always talk to your doctor if you
have questions about your condition. This booklet presents general information and
can help you better communicate with your doctor.
The first part of this booklet discusses chronic pain, spinal cord stimulation, and the
Senza system. It is based on common questions that patients have about their
condition, this particular treatment option, and the Senza system.
The second part of this booklet explains how to use the devices.
In the back of the booklet, we have added some information in the appendices. The
first appendix contains technical information about this product. This information may
be useful to you, but it is not necessary for you to understand it in order to use your
device. The second appendix shows pictures of the parts of the Senza system.
Throughout the booklet, we have provided definition of medical or electronic terms in
a shaded box with a definition.
STIMULATION. Small electrical pulses produced by the SCS system delivered to your
spinal cord to provide therapy for your pain. Spinal cord stimulation is sometimes
called “therapy delivery.”
ABOUT CHRONIC PAIN
Everybody feels pain when there is a painful external stimulus such as a pinprick or
touching something hot. This is referred to as acute pain and is an important normal
sensation that helps protect against injury. Chronic pain is very different. People with
chronic pain may also feel pain when there is no obvious reason or may have pain that
does not go away long after an injury.
CHRONIC. Something that persists or lasts for more than 3 months. Chronic pain is
pain that does not go away with the passage of time or as the body heals from an
injury.
Chronic pain can be intractable, which is the medical term meaning that it is hard to
treat. You have probably tried many treatments to control your pain and found that
they did not work well or perhaps they did not work at all.
