INTRODUCTION TO TENS

What is TENS?
Transcutaneous electrical nerve stimulation is a pain control treatment. It is often called TENS for short.

A TENS unit is a portable, pocket-sized, battery-powered device.
The TENS unit uses mild, safe electrical signals to help control pain and delivers the electrical signal to the body through self-adhesive conductive electrodes.

How does TENS work?
The most common TENS programmes use high-frequency stimulation, which is the first choice for both acute and chronic pain. High-frequency stimulation sends impulses to the nervous system’s own pain-inhibiting mechanisms, which block the pain. You can use it as often and as long as you like, but each treatment should last at least 1 hour.

Another type of TENS is low-frequency stimulation. Low-frequency TENS treatment can alleviate pain by stimulating muscles to release the body’s own morphine-like substances, endorphins.

Place the electrodes on a muscle in the painful area so that a visible contraction occurs.

INSTRUCTIONS FOR USE

Once you are familiar with the features and general operating instructions, Please follow the steps below.

1. Make sure both inputs of the Painless TENS unit are connected into the snap-pin connectors of the gel electrode pad or pads.
2. Peel off the plastic film from the opposite side of the butterfly or standard gel electrodes supplied.
3. Place the Painless TENS attached to the gel electrode pad onto the treatment areas. Press down firmly and ensure a full and firm contact is made with the skin.
4. Press the On/Off power button to turn on the TENS module as indicated by the LED light being green.
5. Turn on your remote control you should hear two beeps this indicates the remote and tens modules are responding. We recommend starting with M1 as this is ideal for first-time use.
6. Once you have set M1, increase the intensity slowly by pressing the + button. Set a level that is a pleasant sensation and not too strong.
7. To turn off your remote by pressing the ON./OFF button, this will also turn off the intensity of the TENS module the green light on the TENS module will stay on. This feature allows you to turn on your TENS module again if required. If your remote is not activated again within one minute your TENS module will turn off automatically.

Pairing the Modules to the Remote Control.
The TENS Modules must be switched on before the remote control is switched on, this is to ensure that the modules pair to your remote control.

A double beep will indicate pairing was successful. You can use either one or two TENS modules at the same time for the best pain relief.

For example, you would always use both TENS modules to treat sciatica. As one module would be placed directly over the lower back (L5 = Lumbar Vertebrae 5).

PAINLESS TENS PROGRAMMES

Below is the table of programmes available:

A MODE – PROGRAMMES A1 TO A6
Programme A1 – is a set frequency programme of 80Hz this is the most common setting used by N.H.S pain clinics for chronic pain-relief.
Programmes A2 – A6 are modulated frequency programmes 20Hz – 100Hz.with a set pulse width of 120 microseconds.
Modulated TENS is ideal for long-term use varying the frequency during treatment reduces the factor of TENS accommodation.
Try each programme A1 – A6 to see which helps with the best pain relief.

M MODE – PROGRAMMES M1 TO M9
The M programmes are set frequencies with 120-microsecond pulse width.
Each programme has 3 modes again reduces the accommodation factor.
Try each programme M1 – M9 to see which helps with the best pain relief.

USING YOUR MODULE INDEPENDENTLY

You may use the TENS Module in a standalone mode without the use of the remote control. To do this follow the simple steps below.

1. Turn on your TENS module by pressing the On-Off button once your TENS module shows a solid green light.
2. Connect one large pad or 2 smaller pads and place on the treatment area.
3. To increase the intensity press the + button to the desired level each press increases the intensity allowing approximately 10 to 15 seconds for the intensity to reach the desired level.
4. Your TENS module has 3 available programmes in stand-alone mode to change the programmes hold down the button for 3 seconds, then increase the intensity as already described. The treatment time in stand-alone mode is set at 60 minutes.

ELECTRODE INSTRUCTIONS FOR USE

Turn Stimulator OFF before applying or removing electrodes

Application of the self-adhesive pads & aftercare
The electrode pads have a maximum usage of 25-30 applications to keep your pads in good condition apply a small amount of water to the gel side of the pad every 4th application (do not over wet). Do not apply any gels or creams to the pads as this will destroy the hydro-gel on the electrode pad.

Application

1. Skin site must be very clean and dry, dirty, flaky or oily skin will prevent electrodes from adhering to the skin. If necessary, trim excess hair with scissors. If skin is oily wipe down with an alcohol or electrode skin prep prior to application. Be sure to wash hands before handling electrodes.
2. Remove electrodes from bag and reseal bag to protect remaining electrodes.
3. Insert the stud electrode on to the back of the device.
4. Grasping a tiny edge of the electrode, peel and remove electrode from the protective plastic liner. Save liner for electrode storage.
5. Place electrode onto skin treatment site (as recommended by your clinician) by firmly applying from the center of the electrode to the outer edges. Adhesion improves when electrodes reach skin temperature.
6. If gel appears over-saturated with excessive moisture or perspiration, allow the electrode to air dry in a refrigerator with the gel side facing up until the gel regains its tack. If the gel appears dry, try adding a few drops of water to the gel and allow to rest in a dust-free environment until the gel regains its tack.

ELECTRODE INSTRUCTIONS FOR USE

Removal and storage

1. Lift a corner of the electrode and slowly peel the electrode off the skin, touching the adhesive gel as little as possible.
2. Place the electrodes back onto the saved protective plastic liner.
3. Return the electrodes back into the storage bag and reseal tightly to prevent dry-out.
4. Store at room or cool temperature and keep out of direct sunlight.
5. The life of the electrode varies depending on skin conditions, amount of use, storage and climate. Electrode life may be extended by carefully following the application, removal, and storage instructions.

Caution

1. DO NOT place electrodes on broken skin. If skin irritation develops discontinue use. Consult physician. Replace electrodes when they do not adhere or when treatment becomes uncomfortable.
2. DO NOT use unit while driving or operating machinery
3. DO NOT wear electrodes when showering, bathing or swimming
4. DO NOT apply electrodes across the head or across the heart or on the front neck.
5. Keep electrodes separated during treatment
6. DO NOT exceed 0.1 watts/cm2
7. Using stimulation electrodes that are small or incorrectly applied could result in discomfort or skin burns.

TROUBLESHOOTING

When the TENS is switched on, pushing the + button, if the device emits 1 bleep and the green light flashes once, but you feel no sensation through the electrode pads this may be due to the following conditions:

1. The TENS Pads are not securely fastened to the skin.
2. The area being treated is to dry please remove your pads and rub warm water into the treatment area and reapply the pads.
3. The electrode pads need replacing.

Please note self-adhesive pads need replacing after 20-30 applications. To increase the life of your pads smear small amount of water onto the pad every 4th application.
If your device is not operating properly please check for common problems and suggested solutions. If the recommended action does not solve the problem, please contact the seller.

Stimulation is weak or non-existent

• Be sure skin is clean and gel electrode pads are firmly attached to the skin.
• The battery is low and needs to be charged.
• The gel electrode pad needs to be replaced.

MAINTENANCE, TRANSPORTATION & STORAGE 21

1. Turn off the device before cleaning.
2. The electrode pad of the device can be cleaned with a soft and wet cloth.
3. Never use excessive water or cleaning agents to clean the device.
4. The gel electrode pad can remain on the control unit between uses, and are covered by the plastic film to avoid getting dirty and dry.
5. Avoid exposure to extreme moisture or temperature.

HELPFUL TIPS

Once you have familiarized yourself with the controls and features of your TENS device, it is important to place the TENS electrodes in a position which gives the most pain relief. This may take 3 or 4 attempts to find the most suitable position, for maximum pain relief.

If you are using two electrodes, place the electrodes directly onto the painful area at a position where you feel the pain starts and where it finishes. You may now position the electrodes around the painful area to locate the most suitable position for maximum pain relief.

The alternative method is to use four electrodes surrounding the painful area see examples below

The complete area between the electrodes will now be treated when positioning the electrodes as shown.
