A TENS machine (or nerve stimulator), is a portable electrical impulse generator connected to electrodes placed on your skin. A TENS machine works by delivering small electrical impulses to relieve nerve, muscle, or joint pain, offering you pain relief anytime you need.
TENS machines offer you a non-invasive, drug-free method of pain relief. They can be used up to 3 times per day, for a maximum of 30 minutes, and they offer pre-set programmes for specific parts of the body as well as fully customizable treatments targeting your individual needs.
Here’s how to use TENS machines in 3 simple steps: Place the pads 2,5 cm from each other on dry, clean skin. Next, turn on your OMRON TENS unit and press the “set/start” button to make your selection. Finally, select the level of intensity that you need. You should start from a lower intensity until you feel that it is having a beneficial effect whilst still comfortable.

Electrical signals are sent via ‘electrode pads’ to specific points on the body. This causes the muscles to react. As a result, two things happen:
1. Muscle pumping action:
By applying low-frequency electrical waves to a body area with stiffness/tiredness, muscles contract and extend (relax)
Muscle contracts: blood containing ‘waste’ is flushed out
Muscle relaxes: fresh blood rushes in
By this repeated ‘muscle pumping’ process, blood flow is improve
> Shoulder stiffness, tired legs and cramps are relieved.
2. Shutting out pain signals:
By applying low-frequency signals to the painful area, the nerves near this area are stimulated, which affects the pain-transmission mechanism (‘inhibits’ pain messages) towards spinal cord. These have relatively short effect. Frequencies: 2 ~ 100Hz.
Electrical waves also stimulate the human body to produce natural Morphine-like substances (endorphins). These have a much longer effect (5 ~ 12 hrs).
Frequencies: 100 ~ 1200 Hz.
>As a result, the sense of pain is relieved.
The Electrode Pads, including the Long Life Pads, do require periodic replacement. However, it is often possible to extend the life of the pads by simply rinsing them under a cold water faucet (no soap is required), shaking off the excess moisture, return the pads to the clear plastic cover sheet or the plastic holder (Long Life Pads only), and then place the pads in the refrigerator overnight (not the freezer). This should restore the adhesion of the pads. If it does not, the pads are worn and should be replaced. Contact your nearest OMRON retailer to obtain these.
