Treat Chronic Pain Using TENS





Muscle stimulation for pain relief

No Prescription Pain Relief!

Did you know! that over 100 million people in the United States suffer from chronic pain, a pain that lasts approximately 3 months or more? According to the American Academy of Pain Medicine, chronic pain far surpasses any other disease that affects people in America as well as worldwide.

It is estimated that close to two million people in the US alone suffer from opioid addiction, according to the American Society of Addictive Medicine. Use of TENS for chronic pain treatment is becoming more “the norm” than prescribing opiates.

“Of the 21.5 million Americans 12 or older that had a substance use disorder in 2014, 1.9 million had a substance use disorder involving pain relievers and 586,000 had a substance use disorder involving heroin. It is estimated that 23% of individuals who use heroin develop an opioid addiction.” American Society of Addictive Medicine. Needless to say, chronic pain is a problem for people on a worldwide scale.

If I told you there was an option for pain treatment that was completely natural, with no medication involved, one that you could begin using in the comfort of your own home, would you at least be interested in hearing more about it? There are countless testimonials from people who suffer from chronic neuropathy related issues that will tell you that use of TENS, transcutaneous electrical nerve stimulation, alleviated their pain.

The Difference Between TENS & EMS

The Difference Between TENS & EMS


What is the difference between TENS vs EMS?

One of the most commonly asked questions here at FlexTone is, “What is the difference between TENS and EMS?” Most people assume that TENS and EMS are similar enough to be interchangeable. FlexTone 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.


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.

“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

The usefulness of TENS ranges from typical everyday 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.” Source


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 performs 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. Please check out our Strenght page to find out more about EMS.

The simplest way to explain the differences is EMS mode goes directly to the muscle and causes a noticeable movement and contraction to the muscle, and the TENS signal bypasses the muscle and goes deep to the nerve to block pain. EMS is helpful with muscle recovery, muscle strengthening, or massaging of sore muscles.

A person who has pulled a muscle or has done an intense workout would use EMS. Massaging of the muscle group assists with the decrease in recovery time. EMS should be used for recovery, rehabilitation, strength, and toning. TENS should be used to treat pain. TENS blocks the pain signal, increases blood flow (quicker healing), and enhances endorphin production.

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. Some treatments may require both TENS and EMS during the treatment process. 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. Flextone devices offer the best of both with our world-class electronic russian muscle stimulators.

How StimRx EMS works for strength

Effects of EMS on Vertical Jump Height

A study investigated the influence of a 4-week EMS, or electrical muscle stimulation, training program on the strength of the knee extensors and the vertical jump performance of 10 basketball players.

EMS sessions were used 3 times weekly; each session consisted of 48 contractions.

Testing was carried out before and after the EMS training program (week 4) and once more after 4 weeks of normal basketball training (week 8).

At week 4, isokinetic strength increased significantly (p < 0.05) at eccentric and high concentric velocities between 180 and 360 x s(-1); this was not the case for low concentric velocities (60 and 120 degreess (-1).

EMS training increased also isometric strength at the two angles adjacent to the training angle (p < 0.01). Squat jump increased significantly by 14% at week 4 (p < 0.01), counter movement-jump showed no change.

At week 8, gains in isokinetic, isometric strength and squat-jump performance were maintained and the counter movement jump performance increased significantly by 17% (p<0.01).

EMS as part of a short strength-training program enhanced knee extensor strength and squat jump performance of basketball players.

(Electric Muscle Stimulation)

Electric Muscle Stimulation, or EMS, is a revolutionary muscle exercise concept for use now in your home, office or on the go.

Electrical muscle stimulation works by sending safe, gentle, electronic impulses to contract muscles.

This electric stimulation is similar to the message the central nervous system sends causing muscles to contract during a workout. The electronic impulses travel from the EMS unit, through lead wires to self-adhesive electrodes, or rubber electrodes that adhere to the skin above the muscle.

EMS is a tool for toning, strengthening and building muscles, rehabilitation of muscles, and pain management. Physical therapists, chiropractic doctors, and professional athletes have used EMS devices for many years.

Now with over-the-counter EMS devices, the general public is enjoying the benefits of Electric Muscle Stimulation as well.

FlexTone, formally known as StimRx, is one of the leading providers of innovative cutting-edge and state-of-the-art TENS and EMS devices in the world. With a large product pipeline and collaboration with JKH Health, FlexTone is consistently innovating and delivering high performance devices direct to consumers and throughout various distribution channels.
