1 | Introduction
The device is a small, portable device that consists of a power source, one
signal generators and an adhesive electrode pad. It activates the body’s own
painkilling mechanisms, which sends low-intensity electrical pulses to the
nerves below the skin relieving chronic pain in a range of cases.
It has been backed by studies conducted over the world that have proved
that tens for pain is very eff ective and has none of the side eff ects.
The mini TENS 4508 is very easy to use and very discreet. Its small size makes
it convenient to wear all day and this allows you to reduce pain and return to
an active lifestyle.
1.1 | Medical background
Explanation of pain:
Pain is a warning signal -we need these signals to tell us that something may
be wrong with our body. Without this signal, we could not know that some-
thing in our body may be impaired or further damaged. However, once we
have identifi ed damage, pain serves little purpose.
Pain does not begin until coded message travels to the brain where it is de-
coded, analyzed, and then reacted to. The pain message travels from the
injured area along the small nerves leading to the spinal cord. Here the mes-
sage is switched to diff erent nerves that travel up the spinal cord to the brain.
The pain message is then interpreted, referred back and the pain is felt.
1.2 | 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 physiotherapists, other caregivers and top athletes around the
world.
High-frequency TENS
activates the pain-inhibiting mechanisms of the nerv-
ous 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. The pain is not perceived.
Low-frequency TENS
stimulates the release of endorphins, the body’s nat-
ural painkiller.
