1. FOREWORD

1.1 Introduction

The LG TEC Multi is a battery operated pulse generator that
sends electrical impulses to the body and reach the nerves and
underlying muscle group, this is a unit to be used for pain relief,
muscle stimulation and massage. The device provides two
controllable output channels, each independent of each other,
an electrode pair can be connected to each output channel. The
parameters of units are controlled by button. Its intensity level is
adjustable according to the needs of patients.

1.2 Medical background

What is TENS?
TENS (Transcutaneous Electrical Nerve Stimulation) gives
good results in acute and chronic pain conditions of many
kinds. It is clinically proven and used daily by Physical
Therapists, other 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 painful area,
stimulate the nerves to block the pain signals to the brain, and
the pain is not perceived. Low-frequency TENS stimulates the
release of endorphins, the body's natural painkillers.
TENS is a safe treatment method and has, in contrast to drugs
and other pain relief methods, no side effects. It may be
sufficient as the only treatment form, but it is also a valuable
complement to other pharmacological and/or physical
treatments. TENS does not always treat the cause of pain.
Consult your doctor if pain persists.
How Does TENS Control Pain?
The device provides pain relief in two ways. The first is the gate
control method. When the body is injured, both pain and non-
pain impulses are sent to the brain from the nervous
system.These pulses travel through the cutaneous nerves to
the deeper, afferent nerves, and then to the spinal cord and
brain. Along the ath are many areas referred to as "gates,"
