You should know that the technology is constantly changing and we can expect wonders coming ahead in nearly every field of medical wonders, one of which is pain control.

Having pain is a common issue especially once you reach the age of 30 or above.

Some very interesting interpretations of the tens units:

  • TENS machine relieve tense muscles or tense nerves.
  • TENS machines are the machines that can function for many different bodily pains.
  • TENS machines produce intense electronic impulses

But all these above mentioned descriptions are meaningless and are only based on some false interpretations. What actually is a TENS machine? Let’s talk about it in the below sections.

What is a TENS Unit?

A TENS unit is a small machine that is named for the process called Transcuteneous electrical nerve stimulation . These units are meant to transmit electrical impulses through the electrodes that are attached on the surface of the person’s skin. The bandwidth, intensity and the frequency of the impulses can be controlled according to the needs of the user.

These units come in various forms and sizes and hence can be very helpful in treating the pain issue within a human’s body. These units are highly effective in treating pain spot efficiently without any side effects.

These TENS units consist of a electrodes that are attached to the user’s skin where the impulses have to be delivered, a connecting cable to the transmitter and an electrical impulse generator and transmitter. The bandwidth, the frequency and the intensity of the impulses that are to be produced are determined through setting made on the unit by the user.

The unit runs on a rechargeable battery that you put into the unit and it creates electrical impulses . The impulses are then transferred to the pained area through the electrodes that are being attached to the skin surface. From there the electrical impulses are delivered to the sensory system.

Though there are many other ways that have been used treat painful muscle and bodily areas like pain relief therapies, medicines and exercises, the TENS units are proven to be effective and have very little health risks.

Why Use a TENS Unit?

TENS units have a wide range of applications and can be used to bring in pain relief under various painful conditions a person might be suffering from. A tens machine is useful in treating muscular pain. The most common uses and applications of such machines are as follows:

  • These units are very helpful in treating back pain and neck pain. You can easily use these units to reduce and avoid muscular pain through the nerve impulse control. These machines are helpful in treating chronic muscular pain in the back and neck area and help to reduce future pain in the affected area.
  • These units are also very effective at treating joint pain caused by muscular issues or muscle tension. You can use it to reduce the chronic pain in your knee joints and shoulders as well.
  • TENS units are also used on women undergoing labor pain. But it should only be administered when the pain is mild or at a minimum level, and the mothers are able to bear with it by using the TENS machine.
  • These are also helpful in treating migraine headaches. In case you have chronic pain in your head region, these units could be very helpful in relieving the pain with a proper usage of regular impulse provided through the tens machines.
  • Other applications may include chest pain, travel sickness, tooth ache, general tiredness,period pains and all such cases where the actual cause is very well known and can be relieved through blocking/stimulating nerve cells.

These units have a wide range applicability and be used easily in a condition when the pain has been diagnosed as a cause of muscular fault or issues in nervous areas. But in case you don’t know the exact cause or the level of complication and the basic cause of the pain symptoms, you should first consult a physiotherapist to help you decide about using the Tense unit.

Can everyone use a TENS unit? Who should not?

As described earlier, these units have no side effects related to usage and can easily and effectively be used when there is a need to reduce pain symptoms in the body. These units are suitable for all and can be used for sure.

But in cases when a person has some serious health issues or has an imbalanced nervous electrical discharge or is already using another device, should always be careful in using these machines or should avoid using it.

For example

  • An epilepsy patient cannot use this unit because he/she already has disruptive nervous electrical discharge and if the unit get applied it will worsen the condition.
  • People who have skin sensitivity issues, should also consider consulting a doctor before using or applying electrodes on the skin
  • Another exception is with the people who are using pacemakers. Such a machine would not work when you have got another electrical stimulation device working within your body.
  • Also, mothers who have gotten intense labor pains are not at all advised to use these units, rather it can only be used under the supervision of a physiotherapist in a controlled way when the pains are in their initial stages.
  • People who have suffered or are currently suffering from cognitive or brain related diseases or issues should also not try out or use these units.

What are the health benefits of a TENS machine

Talking about the health benefits of a TENS machine, we should not limit it to the pain relief of the user’s body, but we should also consider the extra benefits this machine can bring into your life. The machines have become very popular due to the low risk factor and a wide range of its applicability to treat various pain symptoms without any issues. Another major aspect that has contributed a lot in the success and popularity of these units is its flexibility and customizability to adjust according to the required level of impulse generation.

Now if we see on the benefits that a TENS machine is able to bring to our lives, there are discussed as below:

1. A complete remedy for bodily pains

These units are totally risk free when used for bodily aches that have been diagnosed by certified medical practitioners and are based on nervous and muscular issues or strain. These little units can work wonders for chronic pain patients, either its in your back muscles or in neck, knees, chest or shoulder pains. These units are well known to provide comfort and instant and long lasting relief from pain without posing any risk to other parts of your body.

2. Get rid of pain killers

You can easily get rid of pain killers and reduce or eliminate the chances of developing dependency on chemicals and tablets you take for pain relief purposes. You can simply use these machines to increase the activity or healthy internal functions and decrease the chances of pain symptoms.

3. Increases your body’s own pain killing ability

When you use the TENS units at a lower frequency, then it can serve you to initiate the body chemicals called endorphins, which have pain killing abilities and are naturally produced by the internal systems of the human body and these bodily chemicals enables the body to fight and reduce painful feelings naturally.

4. Very easy and portable

These machines are very easy to use and the electrodes can easily be attached and the machine is a very small and light which can be attached to your belt and it can function anywhere you need it except in a vehicle or a car.

Types of TENS machines available

Basically, there are three kinds of TENS machines that are available out there which are as follows:

1. Analog TENS units

These units are a little bulkier as compared to other types and have a limited control over their functions. They have 2-3 knobs or dials that are used to determine the frequency and bandwidth of the electrical impulses, while their timings are preset and can only be changed within the given range.

2. Digital TENS units

Digital TENS machines are a lot better as compared to the analog unit. It is because these have a greater level of control and varied options for settings. You can set up timings, frequency and bandwidth without any preset limits being applied. They are also smaller in size and have more functions to apply.

3. Combination TENS units

Combination TENS machines come with a dual function. These can work as a TENS as well as an EMS machine. Where the tens machine work to reduce pain through nerve functions, EMS machines are meant to work on muscle tissues to strengthen the muscles, relax the tissues and help reduce fatigue effects. Dual function or combination machines can work in both settings.

You should be clear about the type of TENS machine you have to buy.

How it works to relieve pain?

Now, after knowing all the necessary features, options and aspects, what comes next? Of course, the mechanism that a TENS unit uses to create soothing effects and help reduce the pain in a natural way.

Basically, the whole mechanism is straightforward, the electrodes are attached to the affected area on the body and the unit is turned on and set up to generate the required electrical charge having the set amplitude, frequency and pulse rate you need or is suitable to treat your issue. The electrical impulse is carried to the body through the wires to the electrodes and through electrodes to the sensory nerves that are within the area that is to be treated. The electrical impulses are then carried to the brain where it reduces the pain by acting on the neural pathways.

The mechanism has been defined and explained using two of the theoretical paradigms that are:

The neural gate process:

The first explanation which is given to describe the whole mechanism that is used by the TENS units is the creation of an inhibitory Gate within the neural pathways. It has been said that at high frequency rates when the TENS machines are used to generate impulses having the frequency rate of 90-130 hertz, these impulses create a gate between the message carrying nerves and the brain receptors. This gate is then used to inhibit the neurotransmitters that carry pain impulses, to reach the brain and in this way the message is not transmitted to the brain and the person will not experience pain any more.

The endorphin theory

The second explanation is the induction of endorphins within the body. This explanation is for TENS functioning when a very low frequency current is used, that is about 2-5 HZ. Creating such electrical impulses causes the body to excrete pain reducing neuro-chemicals that act like that of the morphine to reduce or eliminate pain signals.

Are there any health hazards of using a TENS unit?

Using TENS units are safe for everyone, who have pain issues that have already been diagnosed as a cause of muscular tension, nerve tension or some neuro-muscular issues.

But exceptions are there, when you use the unit in exceptional ways, then, chances are there that you might get into unusual issues that are not there when the unit is used in a normal and appropriate manner.

For example

  • If you use the unit for a very long period of time and also don’t prefer to cleanse your skin before attaching the electrodes then you might experience some itching or skin irritation issues. But this issue can easily be avoided through, proper cleaning of the skin and proper usage.
  • Further, you may feel muscle twitching or mild cramps if you set the unit to generate high frequency impulses having a higher amplitude. You should always try to keep the settings at a mild level to avoid any such issues or else you can follow the instructions as given by your physiotherapist.

Best practices to use TENS unit

Using a TENS unit is easy but still needs some important and crucial things to know about it.

  • The first step in using a TENS unit is to place the electrodes on the skin properly.
  • Be sure to place them after you have cleansed the skin by using an alcohol swab.
  • Make sure the amplitude is set to the zero position before you attach the electrodes.
  • Set up the frequency and bandwidth. This is very important because the way to set up the electrical impulses will determine how intense would be the action.

For example: If you need to set the mode at higher frequency which can be above 80 or so, you should know that the bandwidth should be set as an opposite value. Meaning that the higher the pulse rate, the lower should be the bandwidth.

The formula you should use would be:

↑ pulse rate=↓bandwidth

↓pulse rate=↑bandwidth

Like if you choose a pulse rate of 100hz then it would be best to use a bandwidth of 70-80µs.

  • If you have severe pain then the best thing you should do is to set up a higher bandwidth and lower pulse rate.
  • Set up the module very carefully. If you need to use normal or continuous, Pulse mode or burst mode.
  • Normal mode delivers an electrical charge in a balanced way, while in pulse mode, you will get a regular shift of about 50 of charge high and low values. In burst mode the settings are set with 100Hz pulse rate and a 100µs bandwidth to give you the exact level of “buzz feel”.

For how long a TENS unit should be used?

The timing depends upon the nature of the pain and the relief level you need to achieve.

  • It would be best if you use the TENS unit for about 30-60 or 45-60 minutes per session.
  • If you have to go with a low frequency mode, then a prolonged usage will only work if you set the frequency with 2Hz, in other case if you set it above 4 the effectiveness of the TENS impulses will fade away due to the production of the endorphins in the body.
  • You can repeat the procedure after every 90 minutes.

How to maintain your TENS machine

TENS units can serve you on a long term basis, and can be a long lasting health partner if it is maintained properly. Here are some important things you should know about keeping your TENS unit in a proper condition:

  • Always keep the battery of the unit fully charged so that it could serve you as you require
  • Always keep the unit away from water or avoid spilling water on it as if you don’t, the unit may not work properly or can get destroyed.
  • Be sure,that you don’t slip or drop the unit frequently, and also never put any heavy thing right on its front, as it will change or ruin its operations.

Cautions while using a TENS machine

Some extremely important things you should know about using the unit safely:

  • Never put electrodes on a ruptured, irritated or allergic skin.
  • Never use the machine in a vehicle
  • Never use the unit when you already have a pacemaker in use.
  • Never put the electrodes on your skin when the amplitude setting is one and set to high level.
  • Never use it with heat pads.
  • Never put the electrodes on the front part of the neck as it will cause blood pressure to fall down. Also, putting them in front and back of the chest area simultaneously can cause heart issues as the charges will cross the heart for sure.

How to buy and where to buy?

Now, You have got through the whole information that you may need to assess any TENS unit and can easily get up to pick the right one for you. Here is a step by step process to help you out:

  • Decide about the type of machine you need
