What is TENS Therapy?

TENS therapy for pain

Transcutaneous Electric Nerve Stimulation, or TENS, for short, is a form of non-medicinal pain relief. The therapy is administered using a special machine that uses an electrical current. This form of pain relief can be extremely useful for those who suffer from joint and muscle problems and is considered to be very effective because of how it works.

TENS therapy sends small electrical signals directly to the area where the pain is occurring. When we experience pain, natural electrical signals are sent to the brain. This results in us feeling a sensation. In the simplest term, the feeling of pain is a primal way that our bodies let us know that something isn’t right.

When the TENS machine’s electrical signals reach the point of pain, this interferes with our natural electric signals, therefore, blocking them from reaching the brain and reducing the pain we feel. In addition to this, the muscles will relax and since this is often a cause of pain, the reduction in tension will reduce discomfort.

There is also the benefit of the release of endorphins. These hormones are considered to be our natural painkiller and the TENS electrical impulses can encourage their production.

What Type of Pain Can a TENS Unit Treat?

One of the greatest things about a TENS unit is that it is able to treat a versatile number of conditions. For seniors who are living with several different types of pain, this may be a viable solution.

  • TENS is often used to treat arthritis which is a common condition for many people in their later years. Studies have shown a reduction in pain for patients with osteoarthritis and this may limit the need for medications.
  • For those suffering from chronic pain, TENS is thought to have a positive effect and there have been several studies to back this up. The Nursing Times states that ‘there was a positive analgesic outcome in favor of TENS treatments’ when referring to chronic pain.
  • According to the NHS, TENS treatment can be effective for various types of pain around the body, notable neck pain, knee pain, and back pain. It may also be effective for sports injuries.
  • There has been evidence to suggest that TENS may also be useful for those who are treating wounds such as ulcers. Not only may it relieve pain, but the treatment has also been shown to effectively decrease the overall healing time.
  • TENS is often used to soothe menstrual cramping.

Is TENS Treatment Suitable for Everyone?

While TENS treatment is effective for many things, there are some patients who may find that TENS therapy is not suitable for them.

  • Patients who have a pacemaker fitted should avoid TENS therapy. However, there are some circumstances where sporadic TENS treatment may be administered in a carefully controlled environment. But generally speaking, pacemaker patients are not recommended for this treatment.
  • Similarly, pregnant women should be mindful of using TENS therapy and it should never be used as the first line of treatment. There is some suggestion that applying the electrical current around the trunk can be detrimental. That being said, some ladies will opt for TENS pain relief during labor.
  • Certain skin conditions may limit where the pads can be placed. Those with irritations such as eczema may find that the TENS pads can cause further skin disruption and should be mindful of this.
  • Those with epilepsy should only ever use TENS therapy under the supervision of a trained therapist. Furthermore, application around the neck and thoracic area could be dangerous.

How to Use a TENS Unit Safely?

Anything that uses an electrical current has the potential to be dangerous. Even if you have no health complications that limit whether you can use a TENS unit, you should still be mindful of safe operation.

One of the major considerations when using your TENS unit is the placement of the pads. There are some areas of the body that the pads should never be applied to. These include:

  • The front of the neck
  • The sides of the neck
  • The eyes
  • The mouth
  • Where there are varicose veins
  • Areas with loss of sensation

Furthermore, if you need to treat the chest and the back, this should never be simultaneous. Each area should be treated one after the other. You should also make sure that the machine is not switched on when applying the pads.

Once the pads are correctly placed, you can turn the machine on. However, for your own safety, you should never begin at full power. You should always start at the lowest setting and increase this gradually until the tingling feels appropriate but not painful.

The pain relief you get from a TENS unit can be very significant and this can make it tempting to overuse the machine. However, it is important to ensure that your sessions do not last longer than 30 minutes. You can do the treatment up to four times a day as needed.

A few other important safety points to keep in mind are as follow:

  • TENS should never be used in water, for example, in the bath or shower.
  • You should not use TENS while you are driving
  • You should not use TENS while you are sleeping.
  • TENS should not be used with heat or cold pads.

Differences Between an EMS & a TENS Unit?

A similar type of therapy to TENS is known as EMS (Electrical Muscle Stimulation) and while the two do have things in common. They are used for different purposes.

TENS is a treatment that targets the nerves and helps to block pain signals to the brain. On the other hand, EMS targets the muscles. This system is typically used for patients whose muscles need to be strengthened during rehabilitation, perhaps after an accident or because of an illness that has weakened them. EMS is also very good for muscle spasms and poor circulation whereas TENS can help with pain and inflammation.

Factors to Consider When Purchasing a TENS Unit

We are fortunate enough to have a huge choice when it comes to TENS machines. But it is important to consider various factors before making a purchase. This is vital to ensure that you get a unit that will meet your needs and be safe to use. Here are some factors you will want to consider:

FDA Approved

The FDA approves medications and products that are known to provide benefits. Not only will this give you the peace of mind that the device will be effective, but it will also reassure you that it offers safe operation.

If the unit also boasts an EMS feature then it is even more important that the device has been FDA approved since this type of therapy is normally done under the observation of a physical therapist.

Programs & Therapy Modes

These devices will typically come as either a TENS-only machine or a TENS and EMS system. The latter is better for people who need both pain relief with the addition of muscle strengthening. However, since EMS is normally prescribed by a therapist, you should carefully follow your therapist’s advice when administering this type of treatment.

You will also notice that your TENS machine may come with a variety of preset programs. These will have varying pulse durations and run for different lengths of time. They may also have varying degrees of intensity.

Normally, the more preset programs that a TENS unit comes with, the more expensive it will be. For patients with more complex needs, versatility is an important feature.

Channels

When you are looking at a TENS machine, it is important to check out how many channels there are. The channel refers to the number of electrodes that the machine can handle. Each channel allows for two electrodes.

Depending on the size of the area you wish to treat and how many locations around the body you need to treat at any given time will determine the correct number of channels. Normally, this information will be given as either a single channel, dual-channel, or quad channel. Most machines have dual channels, allowing you to use four electrodes and this is typically ideal for most users.

Intensity Levels

TENS units that have more than 80mA are normally only available with a prescription. Each unit will vary in its intensity and your level of pain will determine what is right for you. However, it is important to keep in mind that higher intensity machines can cause pain for users and while you should feel a tingling sensation, this should never be painful.

In addition to this, it can be useful to look at the pulse duration. While the intensity will deliver varying levels of tingling, the pulse length can often be altered. If you are using one of the preset programs, this will be done for you but when you are creating a custom therapy session, it is nice to be able to adjust more than just the intensity.

Timer

It is a good idea not to overuse your TENS machine and for this reason, most devices come with a built-in timer. Once the time has elapsed, the machine will automatically shut off. However, in some cases, you are not able to choose the duration of the timer so if this is a feature you want, you may need to search for a TENS unit that is capable of this.

Screen

Your TENS machine will have a display screen and this should be clear and easy to understand. Some units come with a compatible smartphone app and will connect via BlueTooth, this is particularly useful for people who are using the TENS machine in a tricky location and need easier access to the controls.

Power Source

Most modern TENS units are wireless although there is the option to purchase a wired machine if you prefer. The advantage of this is that you get continued power and won’t be reliant on a battery. However, you may be limited as to where you can operate the machine.

If you are using a wireless TENS machine, you should think about the battery. Does it have a long enough running time? How quickly does it charge? Does the machine come with more than one battery so you can use one while the other is charging?

A wireless TENS unit is also extremely useful for people who are on the go. There are compact units that can be worn while you are working or getting on with your daily chores. These are lightweight and especially good for travel.
