Factors to Consider When Choosing the Best TENS Unit

1. Intensity Controls

As we've seen with the fantastic options above, most TENS and EMS units feature a range of strengths that allow you to determine the intensity of electrical stimulation. This allows you to determine which level is best for your level of pain.

The range of strengths varies from machine to machine, and you must choose the unit that features the settings and strengths you want. You can consult your physician if you are not sure which machine is best for you.

2. Treatment Time

Most TENS units come with predefined treatment times, after which they automatically shut off after offering you relief from your chronic pain. For example, some of our TENS machines above have a 30-minute run time treatment timer.

Therefore, depending on your level of pain and advice from your physical therapist, choose the machine that has the timer set to the period you want.

3. Rechargeable or Battery Powered

The way your machine gets its power is another major factor to consider. An advantage that battery-powered machines have is that they are generally cheaper than rechargeable TENS devices, and you don't have to account for charging time.

On the other hand, rechargeable TENS devices cost a bit more but save you the hassle of replacing the batteries now and then. Nonetheless, the power source option boils down to your personal preference as both TENS types do a great job.

4. Channels and Connections

Channels are the number of available outlets where you can connect your lead wires. Usually, one wire that extends from your machine will include two connections for the electrodes. Therefore, a single channel TENS device means that you can use two electrodes at a time.

Most of the options above have a dual channel. This means that each unit offers a chance to use four electrodes at a time. The choice of machine depends on the number of areas you'd like to treat at a time. If you treat a wide area like your back, a device with more leads is the best option.

5. Weight and Size

Factors such as battery size and design affect the size and weight of your TENS unit. If you want a device that you can easily carry around, going for a rechargeable option would be best. Nonetheless, some great battery-powered TENS devices are also easily portable, like our first option above.

6. Combo Units

Choosing to go for a unit that combines both TENS and EMS functionalities depends on your preference. Our fifth option above is an example of a great device that combines these two modalities. However, you don't have to with a combo unit if you don't need it.

Frequently Asked Questions (FAQs)

1. How often should you use a TENS unit?

There's no specific timeframe because many factors influence how often you can or should use your device. Nonetheless, each device comes with an instruction manual that details the recommended length of use. Always read through your manual before use to ensure that you are not exceeding the recommended time frame.

You can also consult your doctor to advise you on how often you can use your unit.

2. Are TENS units safe?

Yes. The consensus is that TENS machines are safe to use to relieve you of your pain. However, always consult with your doctor before using any of these units. Some patients have reported experiencing skin burns and irritations after using these devices.

Therefore, consulting with a medical professional will enable you to go into this form of therapy will the right information and necessary instructions.

3. Can you use a TENS unit while pregnant?

Speak to your doctor for guidance if you are pregnant. We advise against it, although there are opinions that it is safe to use these devices while you're expectant. TENS devices are often used as a natural pain relief option for women in labor. Nonetheless, it's best to consult a medical professional before using it.
