Introduction
The Norco® Eco-Stim™ TENS + EMS is a dual channel output
TENS, EMS and MASSAGE stimulator. Before using, please read
all the instructions in this user manual carefully and keep it in a
safe place for future use.
The Eco-Stim™ TENS + EMS belongs to the group of electrical
stimulation systems. It has three basic functions: TENS
(Transcutaneous Electrical Nerve Stimulation), EMS (Electronic
Muscle Stimulation) and MASSAGE.
Function of the Eco-Stim™ TENS + EMS: The device has 22
programs (9 TENS programs, 8 EMS programs and 5 MASSAGE
programs) and applies electric currents in the low-frequency
range for therapy. Each program controls the generated electric
impulses, intensity, frequency and pulse width.
Based on simulating the body’s natural pulses, the mechanism
of electrical stimulation equipment is to create electric impulses
that are transcutaneous transmitted to nerves or muscle fibers
through the electrode. The intensity of the dual channel can be
adjusted independently and applied individually to one body
part. This dual channel device can be used with four electrodes,
which allow you to stimulate one muscle group simultaneously
with a wide selection of standard programs. The electrical pulse is
first transmitted to the tissue, and then affects the transmission of
stimulation in nerves as well as muscle tissues in the body parts.
1.2 Medical background
1.2.1 ABOUT PAIN
Pain is an important signal in the human body warning system.
It reminds us that something is wrong, without which, abnormal
conditions may go undetected, causing damage or injury to vital
parts of our bodies.
1. FOREWARD
Pain does not occur until encoded messages travel to the brain
where they are decoded, analyzed, and reacted to. The message
is transmitted via different nerves that travel up the spinal cord
to the brain. Pain is felt when the brain interprets the message.
1.2.2 WHAT IS TENS?
TENS (Transcutaneous Electrical Nerve Stimulation) is often
effective for pain relief. It is used daily and clinically proven by
physiotherapists, caregivers and top athletes around the world.
High-frequency TENS activates the pain-inhibiting mechanisms
of the nervous system. Electrical impulses from electrodes,
placed on the skin over or near the pain area stimulate the nerves
to block the pain signals to the brain, causing the pain to go un-
perceived. Low-frequency TENS facilitate the release of endor-
phins, the body’s natural painkillers.
1.2.3 WHAT IS EMS?
Electrical Muscle Stimulation is an internationally accepted and
proven way of treating muscular injuries. It works by sending
electronic pulses to the muscle being treated and causes the
muscle to exercise passively. It is a product derived from the
square waveform, originally invented by John Faraday in 1831.
Through the square wave pattern, it is able to work directly on
muscle motor neurons. The EMS System uses low frequency and
in conjunction with the square wave pattern allows direct work
on muscle groups.
1.2.4 WHAT IS MASSAGE?
The massage function is a non-medical function. The Massage
stimulation program provides relaxing muscle vibration to loosen
tight muscles.
