Frequently Asked Questions

Q1.

What is the difference between a TENS and an EMS unit?

A.

EMS stands for Electronic Muscle Stimulation. It comes under the umbrella of electrotherapy that sends electrical impulses to reduce sores, offer pain control, and increase muscle strength.

TENS, on the other hand, means Transcutaneous Electrical Nerve Stimulation. These TENS units work by stimulating your nerves, releasing endorphins which are natural pain relievers to rehabilitate sore muscles.

In simple terms, TENS and EMS devices use different methods. One is to relieve chronic pain, while the other is for muscle growth.

Q2.

Can you overuse a TENS unit?

A.

Yes, you can overuse a  TENS machine. A lot of the time, if the intensity is too high or if you’ve been using the device for too long, it can result in muscle twitching, among other side effects.

In that case, immediately cease using the device and allow your muscles to relax before starting again, ensuring that the intensity is low.

Q3.

Will Medicare pay for the TENS unit?

A.

Yes, the TENS unit is covered by Medicare only if used to replace drugs dealing with acute postoperative pain resulting from old age or from an injury. If you’re a patient, you need to first consult with your healthcare professional to determine whether you’re eligible or not.

Q4.

Do TENS units build muscles?

A.

TENS units are not designed to tone or strengthen muscles. Instead, they are designed to contract muscles to relieve pain.

Q5.

Which TENS machine is the best?

A.

The TechCare Massager + Reflexology is a powerful Tens machine that offers pain relief in your muscles as well as in your feet.

It also features multiple power levels for the best soothing experience.

Q6.

Do TENS machines actually work?

A.

While TENS machines are not a permanent solution to chronic muscle pain, they can provide temporary relief that may promote healing with prolonged use. These machines have the advantage of being a good alternative choice for a wide range of treatments.

TENS Unit Buying Guide

How to use a TENS unit

These transcutaneous electrical nerve stimulation machines are used for medical purposes to stimulate blood flow in different areas.

Therefore, you need to read the instruction guide, especially the precautions. If you have any confusion, consult with a physician.

Usually, TENS muscle stimulators are operated in the following manner:

  • Before turning on the power, place the electrode pads on the painful areas of your body
  • Start the device keeping it on the lowest intensity
  • Select the appropriate massage modes or select between a variety treatment programs for dual channels
  • Once you’re happy with your choice of massage technique, gradually increase the intensity levels per your liking
  • Set the timer between 10-60 minutes.
  • Now relax and enjoy your massage.
  • Once you’re done, turn off the device before removing the pads or else you can be electrocuted.

Things to keep in mind

  • You should always avoid putting the pads on your mouth, nose, throat, and temples.
  • You should also avoid placing them on sensitive areas such as your heart or swollen and wounded areas.
  • Always avoid touching the surface of the pad as it decreases the adhesiveness.
  • Do not stick the pads on your clothes. Otherwise, you’ll see a reduction in their performance.
  • To make the pads stick properly, add a few drops of water on the surface for conditioning.
  • Always make sure that the battery is fully charged. If you operate the device on a low battery, it can cause damage.
  • Make sure that your skin is clean before placing the pads
  • Keep in mind to put the pads on the holder for longer life.
  • To prevent the wires from breaking, always remove them after use and properly store them.
  • Ensure that you store the TENS device with care in a cool and dry place to avoid any internal damage.
  • If the electrodes do not work anymore, you can simply purchase replacement pads.

Types of Pains that can be Relieved with a TENS unit

TENS units can treat multiple pains by blocking the pain signals from reaching your brain. Examples include:

Plantar Fasciitis

This causes inflammation in your feel along with intense pain.

TENS therapy machines that feature foot massage options are good in combating plantar fasciitis.

Tendonitis

Tendons are thick fibrous cords that attach the muscle to the bone, and tendonitis is the condition that causes inflammation and irritation in the tendon. These are a lot more common in shoulders, knees, heels, and wrists.

TENS devices are made to stop inflammation and irritation and are good for combating tendonitis.

Carpal Tunnel Syndrome

This syndrome is a form of pain caused by excessive pressure on the median nerve and can lead to pain and numbness, weakness, and tingling in your arms and hands.

Dual output machines can easily offer pain relief for carpal tunnel syndrome.

Migraines

Migraines are a type of headache that is characterized by throbbing pain on one side of your head. These can induce nausea, light sensitivity, sound sensitivity, and muscle ache.

Since TENS systems stimulate nerves, they can quickly relieve migraines.

Sciatica

This pain occurs in your sciatic nerve that travels from your lower back to your legs and mostly affects one side of your body.

A TENS device can help by blocking the pain signal due to back pain from reaching your brain.

Nerve Pain

This type of pain is characterized by burning sensations. Most of the time, it goes away on its own, but it can become chronic due to nerve damage or any malfunctions in the nervous system.

Since the function of TENS therapy devices is to stimulate the nerves, that’s why it is quite effective in battling nerve pain.

Neuropathy

This is an advanced stage of nerve pain in which the affected nerves can cause numbness, muscle weakness, and chronic pain. They most commonly occur in your hands and feet but can also affect other body parts as well.

TENS systems are good for providing relief to people suffering from neuropathy.

Fibromyalgia

This is a disorder in your muscles due to lack of sleep, fatigue, memory loss, and mood disorders. This affects the way your spine and brain react to painful and non-painful pulses sent by the different parts of your body.

TENS therapy systems are quite effective in combating fibromyalgia and offering relaxation.

Tennis Elbow

This condition occurs when the tendons in your elbows are overloaded due to the constant motion of the wrists or the arms. This can feel quite painful, especially if you frequently do physical labor.

Manufacturers claim that their TENS units are effective in reducing tennis elbow. However, the devices are not very successful in this regard.

Arthritis

This is the swelling of the joints, particularly the knee. The main issues associated with arthritis are joint stiffness and pain, and they generally increase as you age.

Many  TENS units claim to offer relief to patients who have arthritis.

Muscle Spasms

These are also known as muscle cramps when your muscles involuntarily contract and are unable to relax. Many TENS units have proven to be effective in relieving these spasms and muscle atrophy.

Features of a TENS device

Power Source

A portable TENS unit wi a wireless battery power is the best option considering it allows you to move about and work with ease.

Therefore, the system must have a good and long battery range. Commonly a rechargeable lithium-ion battery is used that is built-in and can offer a battery range from 5-20 hours on a single charge.

Electrode Pads

Electrode pads are mainly used to send electric waves to your skin with the press of a button, which causes a pleasing sensation.

These pads come in different sizes and shapes. However, the majority of them are rectangular.

The adhesive layer is mostly made from gel, but the outer surface is plastic. These pads offer plenty of flexibility, and they can easily stick to different areas of your body, such as the back, hip, wrist, or shoulder.

One advantage of these pads is that once they stop working, you can simply order more placement pads with ease.

Display

This is an important aspect of the TENS unit. This screen is responsible for tracking your usage, allowing you to select modes, indicating the battery power, and access other controls.

That is why the screen must be easy to use; otherwise, it will cause a lot of confusion to the end-user during operation.

Intensity

Variable intensity settings make the body massage more soothing.  TENS units commonly offer intensity type on a scale of 1-20 for pain management.

However, you should keep in mind that an extremely high-intensity level for prolonged periods can cause twitching and make the muscles contract which isn’t a good thing.

So always run your machine at moderate levels for the best massage experience.

Modes

The most important feature of any massage device is the modes it can offer, and the TENS units are no different.

For example, the machines can offer somewhere from 5 to 20 modes depending on the price range. So you can easily pick the one that suits your needs.

Outputs

If you require different types of massages with different intensities on the different body part, you might want to invest in a TENS therapy device that can offer independent dual outputs.

It is a common feature in newer models, but it may not be available in previous versions.

Timer

An adjustable timer is an important feature of a TENS massager because it lets you control the length of a massage session.

Most devices have the option to adjust the timer with 5-minute increments and automatic shut-off so you can take a nap without worrying about overuse.

Portability

These days most of the devices are lightweight and small in size. That’s why you can pack your TENS devices in your bag and take them with you for impromptu massage sessions.

Conclusion

We hope that this review of the best  TENS unit can help you pick the most suitable TENS machine to relieve body pains and lead a more fulfilling life.
