What can a TENS and EMS machine be used for?

TENS machines are normally used along other treatments, like physical therapy. They are becoming more popular for people looking for fast natural relief from pain or worried about potential risks and side effects of opioid medications. TENS machines can be used to get relief from short-term (acute) and longer-term (chronic) pain. EMS machines can help build, strengthen and tone muscle, as well as increase blood flow to help recover faster from sports injury. The devices are often used by physiotherapists, athletes, body builders as part of a training or rehabilitation program. Please click here for a list of Pains that TENS machine can assist with. 

What is a TENS machine?
TENS machines can be used to help manage different types of pain. TENS (transcutaneous electrical nerve stimulation) therapy is when small electrical nerve-stimulating pulses block the feeling of pain. Small pads (electrodes) are put on the skin near the area of pain and non-painful electrical impulses travel from the electrodes across the skin and along nerves to the brain. Portable TENS machines have been around since the mid 1970’s and today you can choose from lots of different machines, including remote controlled compact wireless devices that don’t use wired electrodes.
What is the difference between TENS and EMS?
Although TENS and EMS machines look very similar, they work differently. TENS (transcutaneous electrical nerve stimulation) is for blocking pain. EMS (electrical muscle stimulation) is for stimulating muscles. CareMax stocks a wide range of quality TENS and EMS devices that are designed to be used at home for drug free pain relief, faster muscle recovery and improved sporting performance. And our combination units, with both TENS and EMS functions, are the perfect solution if you’re looking for help with pain relief and muscle strengthening.
Is it safe to use TENS on metal implants?

The major concern is that the applied electrical energy will result in 'significant' heating of the metallic implant, which would have a detrimental effect in the local tissues surrounding that implant, raising the tissue temperature to damaging levels and causing skin burns. However, there is no reference in medical literature to the effects of TENS on implants, other than pacemakers. The signal from TENS/EMS only penetrates about 1cm below the skin’s surface and contains only a tiny amount of energy (just enough to persuade a nerve to send a signal), therefore there should be no side effects.

With this being said, extra care should still be taken when using TENS/EMS on metal implants. In order to avoid any potential risk, the following procedures must be followed:

- Electrodes should be placed away from the proximity of the metal implant, skin staples, skin with reduced sensation or tissues treated with dressings or topical agents containing metal ions.

- Avoid using too small electrodes which create high current density and may lead to a heat burnt.

- Implanted device which is powered by a battery (or equivalent) is an ACTIVE IMPLANT and should be considered to be a real contraindication to many forms of electrotherapy.

If you are uncertain of using a TENS machine on an area in which you have a metal implant, please seek advice from your medical practitioner.

Are there adverse side effects?
No. One of the most unique and welcome aspects of pain treatment with a TENS unit is the complete lack of side effects. The side effects of pain relief narcotics are well-known and can be quite serious, including dependence and addiction. TENS provides an alternative to traditional pharmaceutical treatments with none of the potential for dependency and abuse that these drugs are proven to engender. Many sufferers of chronic pain have turned from narcotic dependency to the TENS unit in order to free themselves from what can become a vicious cycle. The TENS unit offers a safe and healthy alternative for pain treatment.
How long will it take for my TENS to help my pain?
It takes approximately 30 minutes or less to feel the effects. Some people Prefer to use their TENS all day or for several hour at a time. Our TENS Units with an automatic timer can be used to help you go to sleep. Every individual has different needs. If you have two different areas of pain you may use two sets of electrodes (each have two pads) so that your TENS can treat your pain simultaneously.
Will using a TENS hurt or give me more pain?
Absolutely not. If our Tens Units are used as directed your pain may be reduced. You will feel a tiny tingling sensation which is a minor to no discomfort at all. This is because it has a high frequency, which means the stimulation is approximately one hundred times per second. Using our Tens your pain should be lessened or disappear.
How Long will electrodes last?

There are many factors that can influence how long they last. For example:

  • How long these electrodes used at a time (30 Minutes Or 8 Hours). If they are used for a couple of hours a day, We recommend using 2 sets of electrodes. Use the first set the first day and the second set for the second day. This will give the first set about 24 hours to completely dry which will expand the usage time. Repeat these steps by rotating the 2 sets. 
  • If you have a lot of body hair, they will not last as long as if they are placed on bare skin. If possible place them on bare skin. During a hot summer day you can sweat more than during a winter day. Once they get wet they will last less long. Let them dry for 24 hours which will extend their usage time. 
    As you can see there are many factors that can influence the usage time. As a general rule, they will last for 20-30 applications If used correctly as directed in our blog. 
Can I use a standard TENS unit for labour?

Ordinary TENS and maternity TENS work in the same way, Although the ordinary TENS can be used for labour pain management, they are not specifically designed for maternity use.
There are several important, practical differences:
When a contraction occurs, you need to be able to quickly change the way the TENS operates, and then be able to change it back at the end of the contraction. Unlike normal TENS units, the Maternity TENS has a special ‘boost’ button which quickly adjusts the settings when you need them.
Our The more difficult operation in an extremely stressful situation.
Most TENS units have a separate intensity control for each lead. The maternity units have one intensity control for both leads to make things simpler.
In labour the pain is widespread. You need to cover a large area to get effective pain relief. If you do not have the special larger pads which are supplied with the maternity TENS units, then the pain relief provided will not be as effective.
In summary, it is much safer and easier to use Maternity TENS units during labour as they are specifically designed to suit the needs of pregnant

Are there any reasons why I should not use TENS?

Do NOT use TENS under any the following circumstances:

  • If you have a heart pacemaker or have a heart rhythm problem
  • If you have epilepsy
  • During the first six months of pregnancy
  • When driving or operating machinery
  • If you are suffering from acute, feverish or infectious diseases
  • Near heart monitors or alarms
  • To mask or relieve undiagnosed pain


Do NOT place electrodes:

  • On the carotid arteries in the front of your neck
  • Over your eyes
  • Across the front of the head
  • On the abdomen if you are pregnant
  • On the heads of children under 12
  • Near malignant tumours
