Both deliver low voltage electric impulses to stimulate

TENS vs EMS: the main difference between the two:

  • TENS stimulates the nerves – the rationale being that the simulation keeps pain signals from reaching the brain
  • EMS causes the muscles to contract – by mimicking the action potential that comes from the central nervous system

The relief of chronic and acute pain. Some examples include:

  • Arthritis
  • Back pain

  • Foot pain
  • Labor pain

TENS vs EMS: which is right for me?

The two machines have completely different purposes so it’s imperative that you choose the correct device.

If you’re looking to build muscle as part of a training program then a TENS unit is not going to be suitable for you. Likewise, if you are seeking some relief from chronic back pain – an EMS unit might not be the best choice for you.

TENS EMS combination devices

There are a number of combination machines on the market that offer both TENS and EMS.

You can get the best of both worlds with a combination device. While these machines may require a larger initial investment, they are highly versatile.

TENS vs EMS: a combination device that offers both functions

An example of somebody who could benefit from a TENS EMS combination unit is an active sportsperson who works at a desk and suffers from lower back pain.

They would be able to use the TENS function to relieve their back pain and the EMS could be used to help strengthen their muscles as part of their training program.

A combination unit would be a desirable alternative for anybody who wants to use both TENS and EMS. It means they only need purchase a single device, versus two separate ones.

The other advantage of having a single device is portability. People who like to take their machine on vacation, when they’re away on a business trip, visiting friends, etc. only have to carry one device.

Purchasing a TENS or EMS unit

While some TENS and EMS units are prescription only, there are many versions that can be bought over-the-counter (OTC). It is however recommended that one consults the advice of a healthcare provider prior to using a TENS unit.
