How The TENS & EMS Unit Works
The device uses electrical pulses through electrode pads to support both pain relief and muscle stimulation in one device.
TENS, or Transcutaneous Electrical Nerve Stimulation, works by stimulating the sensory nerves in your body. It helps:
- Block or reduce pain signals before they reach the brain
- Make you feel good naturally via releasing the body’s endorphins
EMS, or Electrical Muscle Stimulation, works by sending controlled electrical pulses to activate muscles and create muscle contractions. It helps:
- Muscle recovery & relaxation after exercise, strain, or physical activity
- Muscle activation and re-education
- Muscle strengthening support

TENS & EMS Therapy - Backed by Science
Study 1 - TENS & EMS simultaneously therapy
Authors: M. Zhou, F. Li, W. Lu, J. Wu, S. Pei
Quote: “TENS and NMES can effectively improve HSP, the efficacy of NMES being distinctly superior to that of TENS in maintaining long-term analgesia.”
Study 2 - TENS therapy for pain relief
Authors: Mark I. Johnson, Carole A. Paley, Gareth Jones, Matthew R. Mulvey, Priscilla G. Wittkopf
Quote: “There was moderate-certainty evidence that pain intensity is lower during or immediately after TENS compared with placebo and without serious adverse events.”
Study 3 - TENS therapy for menstrual pain (primary dysmenorrhea) relief
Authors: Marafi Jammaa Ahmed, Wejdan Ahmed Aldawsari, et al.
Quote: “Thirteen RCTs with 779 patients showed that TENS is an effective, non-pharmacological treatment for primary dysmenorrhea, reducing pain intensity, prolonging relief, and lowering non-steroidal anti-inflammatory drugs use.”
Study 4 - EMS Therapy for Muscle Recovery
Authors: K.P. Ramirez, J.A. Mettler
Quote: “These results suggest that muscular endurance of involuntary muscle contraction is increased with NMES training, and that stimulation intensity should be increased throughout the course of training to augment muscular torque output.”
Study 5 - EMS (NMES) Therapy for Muscle Strengthening
Authors: Kevin A. Happ, Michael Behringer
Quote: “The findings indicate that training with NMES results in virtually identical strength gains compared with conventional strength training when training volume is matched.”
Study 6 - EMS Therapy for Muscle Rehab
Authors: Edward J Hardy, Jacob Hatt, Brett Doleman, Thomas F Smart, Matthew Piasecki, Jonathan N Lund, Bethan E Phillips
Quote: “EMS reduces losses of muscle mass and function following major abdominal surgery, and as such, may be the promising tool for post-operative recovery.”

My wife suffers from back pain. Bought this to help in between visits to the chiropractor. She only had to use it one time and if worked the knot out and she had relief from pain. now she can go to play tennis ball with me.

Use this at work since its portability is perfect. It's discrete and really helps with back pain. I've also purchased two additional one for home and one for my boyfriend. Numerous colleagues have also purchased after seeing how effective it was for me. Lightweight, perfect size, and effective. I highly recommend.

I LOVE THIS. MY PLANTAR FASCIITIS HAS BEEN AGGRAVATED FOR SO LONG AND I USED IT FOR A GOOD HOUR FOR DIFFERENT AREAS OF MY LEGS. AND I'M NOT JOKING, THE ACHE REDUCED SIGNIFICANTLY. I PLAN ON HAVING THIS EVERY DAY BEFORE I GO TO SLEEP WHILE LOUNGING WATCHING SHOWS. IT'S A GREAT ITEM.

Frequently Asked Questions
The OneNTech Wireless TENS & EMS Combo unit is an FDA 510(k) cleared product.
“FDA cleared” means the U.S. Food and Drug Administration (FDA) has reviewed a medical device and determined it is “substantially equivalent” to an already legally marketed device (a predicate).
Yes. Evidence shows it is effective for reducing immediate pain, particularly for acute, postoperative, and musculoskeletal conditions. You can find study proof on National Library of Medicine here.
The FDA classifies a transcutaneous electrical nerve stimulator (TENS) for pain relief as a Class II device used to apply electrical current through electrodes on the skin to treat pain.
Yes — EMS/NMES therapy is clinically supported for stimulating muscles, because the basic mechanism is electrical pulses causing muscles to contract.
The OneNTech Wireless TENS & EMS Unit combines the latest TENS (Transcutaneous Electrical Nerve Stimulation) and EMS (Electrical Muscle Stimulation) technologies in a single unit.
TENS helps stimulate the nerves to support temporary pain relief by helping reduce pain signal transmission and encouraging the body’s natural pain-relief response.
EMS helps stimulate muscles by sending gentle electrical pulses that cause controlled muscle contractions, supporting muscle activation, recovery, and strengthening.
TENS mode: users feeling relief shortly after use begins. Results vary by user, pain type, pad placement, and intensity setting.
EMS mode: Muscle activation can be felt right away, while recovery, spasm relaxation, and strengthening support are best achieved with consistent use over time.
- TENS Therapy: Typically 30–60 minutes per session for everyday pain relief support.
- EMS Therapy: Typically 20–30 minutes per session for muscle activation, recovery, and strengthening support.
The OneNTech TENS & EMS Combo Unit is ideal for people looking for drug-free support for everyday body pain, sore muscles, post-workout recovery, muscle activation, relaxation of muscle spasms, and muscle strengthening support. TENS mode helps stimulate nerves to support pain relief, while EMS mode helps stimulate muscles to support recovery, relaxation, and performance.
Do not use if you have an implanted electronic device such as a Pacemaker or Implantable Cardioverter-Defibrillator.
Do not use TENS on:
- Open wounds or rashes
- Swollen, red, infected, or inflamed skin
- Cancerous lesions, or close to them
- Skin that does not have normal sensation (feeling)
- Any part of your head or face
- Any part of your throat
- Both sides of the chest or trunk at the same time
- Directly on your backbone
Do not use TENS while:
- Bathing or showering
- Sleeping
- Driving
- Using machinery
- Turn the TENS unit off before you put on, move, or take off the electrodes.
- Keep out of the reach of children.
Stop using TENS and talk with your doctor or health care team if you have:
- Skin irritation (redness, rash, itching)
- Headache
- Dizziness
- Nausea (feel like you are going to throw up)
TENS Mode:
For pain relief, place the pads around the painful area, usually on the surrounding muscle. Common use areas include the neck, shoulders, back, waist, arms, thighs, calves, knees, and joints.
EMS Mode:
For muscle stimulation, place the pads on sore muscles or target muscle areas such as the biceps, abs, thighs, calves, shoulders, or back.
OneNTech Wireless TENS & EMS Unit is FDA-cleared device, ensuring their safety. However, individuals with pacemakers, infants, and pregnant women are advised not to use the device. If you have a specific medical condition or are epileptic, it is recommended to consult with your doctor or healthcare practitioner before use.
No. No app required. Control everything with the unit itself or/and the control remote.
Rest assured, the TENS & EMS stimulation is not painful. Instead, it produces mild and pulse-like sensations that many people find comfortable.

This TENS unit is fantastic! Just be aware that when you fly with it, you should NOT pack it in your suitcase, especially a check in bag. Keep it separate, then show it and declare that it is a medical device when you go through security then keep it with you in your personal item… I accidentally packed mine when I flew home from California a few weeks ago and it got confiscated. So just to be safe carry ALL items with batteries in your carry on or personal item.
