What is the difference between TENS and EMS?January 11, 2016

Blog

One of the most commonly asked questions here at Stimrx is “What is the difference between TENS and EMS?” Most people assume that TENS and EMS are similar enough to be interchangeable. StimRx wants to make sure you know the differences in the two, and the importance of when to use each of the modes with our equipment. Both TENS and EMS devices use a power supply, lead wires and identical electrodes to supply the electrical impulses to the body.  However, their purpose is quite different.

Most machines offer both TENS and EMS programs to choose from.  You can select not only the level of intensity, but whether you need TENS or EMS at the time of treatment.  Which one do you need?  Hopefully, the following information will make the differences in the two a little more clear.

WHAT IS TENS?

TENS is the acronym for “Transcutaneous Electrical Neural (or Nerve) Stimulation.” Small, low voltage, electrical currents are adjusted by the person using the machine to send stimulating pulses into nerve endings. These pulses assist with decreasing pain by blocking signals from reaching the brain.

TENS Attacks Pain at its source

By stimulating “A-beta” fibers pain signals in the “A-delta” fibers are suppressed preventing “nociceptive processing,” otherwise know as pain. This causes instant relief, which allows you to continue your day pain free! Department of Neurosurgery, Aachen University, Germany

The usefulness of TENS ranges from typical everday pain relief, to acute and chronic conditions. For example, a person with sciatic issues (a nerve problem) would use TENS.  Use of the program can help with blocking pain, as well as stimulate circulation in the area to aid in the healing process. TENS will also aid in the stimulation of endorphin production (the body’s natural painkiller). This means you feel better, longer without the use of addictive or destructive medication.

TENS therapy enhances the bodies natural ability to produce pain fighting endorphins also know as “Beta-endorphins”. These endorphins act to numb and relieve pain and to create a sense of euphoria. Clement-Jones, McLoughlin, Tomlin, Besser, Rees, and Wen

WHAT IS EMS?

EMS, or Electrical Muscle Stimulation, is the use of electrical pulses to generate a muscle contraction. EMS is typically used to enhance muscle strength, performance, and recovery. By contracting the muscle with EMS, you are able to achieve a stronger muscle contraction compared to a natural contraction. This effect produces an increase in the muscle’s ability perform as desired. EMS has been widely used by athletes and Olympians as early as the 1970’s, and is gaining popularity due to its ability to push the body further.

A QUICK WAY TO REMEMBER THE DIFFERENCE BETWEEN TENS AND EMS

The simplest way to explain the differences is 
the EMS mode goes directly to the muscle and causes a noticeable movement and contraction to the muscle and the TENS signal by-passes the muscle and goes deep to the nerve to block pain.

Remember that “nerve” starts with the letter N. EMS is for used for muscles.  Muscle starts with the letter M.  EMS is helpful with muscle recovery, muscle strengthening, or massaging of sore muscles.

WHEN TO USE TENS vs. EMS

There is a lot of contradictory information, even among doctors, as to what a person should/should not do following an intense workout to alleviate DOMS symptoms.  Ice?  Heat?  Alternate between the two?  TENS vs. EMS following a workout?

When to use TENS

A person who has pulled a muscle, or has done an intense workout would use EMS.  Massaging of the muscle group will assist with the decrease in recovery time. Moreover, EMS should be used for recovery, rehabilitation, strength, and tone.

When to use EMS

TENS should be used to treat pain. By using TENS you will block the pain signals, increase bloodflow (quicker healing), and enhance endorphin production.

STIMRX DEVICES

Our FDA Cleared units have the ability to deliver both TENS and EMS. This, in addition to our high quality standards, allows our units to be more helpful and versatile compared to competitor’s units. Moreover, some treatments may require both TENS and EMS during the treatment process. For example, with Knee replacement surgery the analgesic effects of TENS are desired to relieve pain while the effects of EMS are desired to regrow and strengthen the muscles. With StimRx you get the best of both with our world class electronic muscle stimulators.

If you need help deciding which is for you please call our 24/7 support hotline at 1.800.573.8171 for a FREE TENS and EMS consultation.
