More about iReliev Wireless EMS.

EMS works as a passive exercise technique. Its gentle muscle stimulation is comfortable and can often bring its own relief from pain.

In addition to such benefits, EMS also causes the contraction and relaxation of the muscles it stimulates. The repetition of this cycle brings about benefits like increased blood flow, which causes recovery and growth, as well as the prevention of inflammation.

Because EMS stimulates muscles that are otherwise still, it’s also a great way to help prevent atrophy in injured patients or to keep the muscles warmed up during travel. We have thousands of stories from our customers about the benefits they received from using the EMS functionality.

Hand control benefits.

iReliev Wireless is exceptionally convenient, lightweight and portable. The hand control is smaller than most cell phones and fits easily in your pocket. Full backlit display makes therapy in the dark a breeze. Simply set your therapy and duration with the remote which is not required to be in close proximity after therapy has been set which means you can leave it your bag, or purse.

Conceal your therapy with low profile pods.

Easily wear and conceal your use of electrotherapy with portable wireless pods. Pods are 2.35″ in diameter and .55″ in height, truly a design breakthrough for us when you consider that over 2/3 of the pod is comprised of the battery itself.

Rechargeable Battery

The iReliev Wireless is powered by rechargeable batteries that yield 3-5 hours of therapy per pod and 5-10 hours on a full charge of the hand control. Charge with the dual USB cable for charging two devices at one time.

Does iReliev Electrode Pads Made with Gel Contain Salicylate?

iReliev gel pads do not contain salicylate which is necessary for many people seeking to follow protocol consistent with Guaifenesin protocol.  Considered by many as an unapproved treatment for fibromyalgia suggested in the 1990s by R. Paul St. Amand. The protocol involves three parts: titrating the guaifenesin dosage, avoiding salicylates, and following a low-carbohydrate diet if the patient is hypoglycemic.

What is the charging time to full charge?

Charging time for the remote is about 2 hours 20 minutes; Charging time for the receiver pods is about 1 hour 30 minutes.

Does this product help with swelling in the legs and feet?

One thing that EMS does is that it increases blood flow to the area.
Increased circulation is very beneficial when muscles or joints are still for long periods of time.

Can unit be used without the timer?

No, the TENS unit only works with the timer. The minimum time is 5 minutes and the maximum time is 60 minutes. You will have to re-set every 60 minutes for continuous usage.

Do you ship internationally?

Yes, we ship internationally.

Can I use iReliev if I have a pacemaker?

No. iReliev should not be used if you have a pacemaker, defibrillator, or any implanted electronic device. Also, iReliev should not be used if you have any implanted medical devices containing metal.

Can I adjust the intensity?

Yes, since pain is subjective, all iReliev devices provide adjustable intensity allowing you to customize your therapy as to whatever feels comfortable for you.

How long do the wireless pads last?

Pads typically last 20-30, 20 min session assuming proper care is taken. DO NOT CHARGE wireless pods when attached to pads. Increased heat will reduce longevity of pads. 

What is the difference between Transcutaneous Electrical Nerve Stimulation (TENS) and Electrical Muscle Stimulation (EMS)?

TENS sends low voltage electrical impulses through the skin to block the body’s nerve pathways that indicate pain and stimulate endorphins (the “feel good” chemical in your brain).

Electrical muscle stimulation (EMS), also known as neuromuscular electrical stimulation (NMES), is the elicitation of muscle contraction using electrical impulses. EMS is receiving increased attention in the last few years because of its potential to serve as a strength training tool for healthy people and athletes, as rehabilitation modality and a post-exercise recovery tool for athletes.

Can I use iReliev in conjunction with topical pain rubs or gels?

Topical pain creams, rubs or gels can be used before or after the use of iReliev TENS and/or EMS. Please note, topical pain creams should not be applied to the site of pain immediately before applying the iReliev electrode pads. Applying topical pain rubs in combination with the iReliev electrode pads may damage the electrode pads and prevent you from experiencing optimal electrotherapy results. However, many of our customers use gel for optimal electrical dispersion. It can increase conductivity, creating a more comfortable experience while hydrating the moisture of the gel on the original pads.

How does iReliev TENS help reduce pain?

iReliev works by producing electrical pulses that block the body’s pain signal to your brain, thus the pain symptoms you feel. TENS has also been shown in clinical studies to encourage the body to release its own natural pain relieving endorphins, sometimes referred to as the body's “feel good chemical.”

Can I use iReliev while pregnant?

Do not use during pregnancy or if you think you might be pregnant.

Do iReliev products require a Doctor’s prescription (RX)?

Nope. All iReliev devices are FDA cleared over-the-counter (OTC) devices. This includes our latest PlayMakar ET-5050 system, a high output, wireless system.

What is the best mode for arthritis?

Our TENS P8 is the best mode for arthritis.

How long can iReliev TENS and/or EMS be used in a day?

Therapy sessions can last 60 minutes or less. You can use iReliev for consecutive 60-minute sessions according to your pain relief needs when used in accordance with the user manual.

Is this unit Health Canada approved for the TENS and EMS? Or just the TENS?

As of 10-11-17 All of our products are Health Canada approved including Wired TENS + EMS model ET-7070 with the exception of our latest wireless TENS + EMS, model ET-5050 which was submitted about a month ago. We expect to have Health Canada approval in several weeks.

What is the power output of this product?

80mA output or 25 levels of intensity. 80mA is equivalent to many portable prescription models. It is very strong I assure you.

what does the EMS mode do? Is it a massage function?

It is not a massage. EMS will contract your muscles. Depending on the parameters, these currents are used to train, recover or heal the muscles.

Is it necessary to use electrode gel with this device?

No, it is not required as the electrodes are pre-gelled.

Can the intensity selections be manually adjusted during the sessions, or do you have to reset it to get it just right?

Yes, you can change it during a session. Best way to adjust to a comfort level actually.

Does EMS help burn abdominal fat?

Not exactly. EMS can help contract the muscles to build muscle strength through electronic muscle contraction and relaxation. As you may know increased muscle density has been known to help burn fat. EMS has been shown effective when use of the modality is used in combination with resistance training. But no, we do not promote that one can sit on the couch without resistance training and “get rock hard abs”. It requires a low fat diet, exercise and adequate resistance training. iReliev TENS + EMS can help in the overall process.
