What is a TENS machine?

A TENS machine is a small device that uses electrical currents to help reduce pain. TENS (transcutaneous electrical nerve stimulation) therapy uses electrical nerve-stimulation pulses to block pain signals that come from the nerves (Watson, 2018). Small pads (electrodes) are placed on the skin around the affected areas to deliver these impulses to the body. Different settings are available on portable TENS machines to assist with various types of pain conditions.  It helps with sciatica and nerve pain, it relieves migraines and acute pain, it’s good for wound healing, and you can use a TENS during pregnancy and labour.

How do TENS Machines work?

They are a form of electrical therapy used by healthcare professionals, such as physiotherapists and GPs, as a natural form of pain relief for patients. However, TENS can also be used by individuals living with painful conditions, such as lower back pain, muscle spasms, ovulation pain, during pregnancy or sciatica etc.[1].

This portable device is attached to gel pads which are placed on or around the painful areas of the body. Once the TENS unit has been turned on and adjusted, gentle electrical pulses are delivered through the pads. The electrical current creates a tingling sensation which blocks pain signals travelling from the source of the pain to the brain [2].

Currently, how the TENS devices work affects the body is still being researched. However, one proposed theory is that the electrical current provided from the device dulls the effect of the C fibres. These fibres are found underneath the skin to deliver information about any painful stimulus from the affected region (e.g. muscle spasms, inflammation, etc.) [2]. By cutting off the communication from the C fibres via the TENS Unit’s electrical pulses, the painful sensations are reduced and/or removed.

How to use a TENS machine

Before using a TENS machine, it’s important to determine two pieces of information - 1) whether the device is safe for use and 2) what you are using the machine for (e.g. your condition, location of pain, etc.). You may need the assistance of a healthcare professional to determine these pieces of information.

After opening the device from its package, connect the charged TENS device to the electrode pads and apply to the painful area on the body. To guide you through the correct placement, we've prepared a comprehensive TENS machine pads placement guide. Click here to access the guide and learn the best practices for pad placement. Once the pads have been placed on the treatment area, set up the unit by either adjusting or selecting a pre-programmed setting according to the treatment you need. Each device should come with a manual to better explain the settings. Some settings you may consider include [1]:

  • Intensity: Measured in (milliamps) mA, the intensity will determine the strength of the treatment.
  • Frequency: Measured in hertz (Hz), the frequency will determine how quick the electrical pulses are being delivered.
  • Pulse width: Measured in microseconds, the pulse width will determine how long each electrical pulse is.

Once these have been adjusted, you can start the treatment. The treatment duration and sessions per day may vary depending on the chosen setting(s). During the treatment, you will feel electrical pulses on the affected area. Adjust the intensity (mA) of the treatment to as much as you can tolerate without any additional pain or discomfort. Continue until the end of the session, or stop if you feel any unusual symptoms or pain.

Difference between TENS and EMS Machines

Transcutaneous electrical nerve stimulation (TENS) and EMS machines may appear very similar due to their outward appearance. Both are handheld devices that deliver electrical current through the attached gel pads. There are also combination units that have both TENS and EMS settings.

However, TENS and EMS machines are used for different purposes [1]. A TENS machine is primarily used to deliver treatments for helping ease acute (short-term) and chronic (long-term) nerve and muscle pain.  These machines send unique electrical signals to the nerves to achieve the desired effect.  However, an electrical muscle stimulator (EMS) is mainly used to help activate and jumpstart muscles, prepare the body for a workout, increase strength and help prevent muscle wastage. There are many ways EMS can be used, such as improving athletic performance and assisting with rehabilitation

Users will also report that the treatments also feel different. While the EMS causes a strong contraction of the muscles, the TENS treatment will lead to a repetitive tingling sensation.
