iTENS: TENS Medical Device

Physiotherapists, pain management experts, massage therapists, and healthcare providers have been using TENS pain management therapy since the mid-1960s. TENS means Transcutaneous Electrical Nerve Stimulation. It is a form of electrotherapy that uses painless electrical currents to stimulate the nerves to provide pain relief. A TENS medical device is a machine that administers pain management treatment in TENS therapy. They are considered medical devices for electrotherapy in the medical community.

Unlike before, you can now purchase TENS medical devices for personal use. Make sure, however, to choose a medical device that you can trust. The iTENS wireless unit at iTENS Australia is a one of a kind TENS therapy device. Moreover, you can be sure that it is a safe and effective gadget for relieving pain whilst providing increased comfort and convenience. Find out more about the revolutionary iTENS TENS medical device.

What is a TENS Medical Device?

A TENS medical device is an advanced technological machine that transmits stimulation using low voltage electric pulses over the skin’s epidermis to the nerve fibres to inhibit pain signals from reaching the nervous system. It is a small battery-powered device that employs the use of adhesive (sticky) electrode pads. When attached to the skin’s surface, the TENS electrode pads deliver the device’s electrical currents to the skin and then into the nerves. Electrode pad placement is usually at or around the nerves to where the pain location is. Its ultimate goal is to activate neural networks in the body in order to reduce pain. 

Furthermore, TENS therapy using TENS medical devices can treat a variety of pain symptoms and conditions, whether it is short term (acute) or long term (chronic) pain. These include some of the most common conditions such as:

  • Arthritis (more commonly osteoarthritis)
  • Fibromyalgia
  • Tendonitis
  • Bursitis
  • Labour pain
  • Period pain
  • Low back pain
  • Joint pain
  • Chronic pelvic pain
  • Diabetic neuropathy
  • Peripheral artery disease 

How does a TENS Medical Device Relieve Pain?

Pain management therapy using TENS medical devices follows two major theories that result in how they are able to relieve pain. Firstly, when set to a high pulse rate of 90 to 130 Hz, the electrical impulses interfere and block the pain signals. It is under the theory of Gate Control Theory of Pain Management. This theory implies that there is a gating mechanism located in the central nervous system (specifically the spinal cord). When electric stimulation occurs via the use of a TENS machine, the neural gates “close”, therefore blocking pain signals from reaching the brain.

The second theory states that when a TENS medical device is set to a low pulse rate of 2 to 5 Hz, it can stimulate the body enough to produce more endorphins. Endorphins are natural pain-relieving chemicals, often referred to as the body’s natural painkillers. These chemicals are morphine-like in nature. Thus, it can also block pain signals from being felt. Moreover, more endorphin production can result in an improvement in mood and an increase in happiness for individuals. Hence, why they are often called the “feel good” hormone.

Safety Guidelines When Using TENS Medical Devices

TENS electrotherapy using TENS Medical devices is often proven to be remarkably safe. There are very few to no side effects when implementing TENS as your pain management treatment. However, if you have infected or inflamed skin irritations, you should avoid using the device until your skin has healed. Furthermore, you should avoid TENS therapy if you have any of the following conditions:

  • Has an electronic or metal implantable device (like cardioverter/defibrillator, neurostimulators, bone growth stimulator, indwelling blood pressure monitors)
  • If you are in the early stages of pregnancy
  • Cancer
  • Epilepsy
  • Thrombophlebitis
  • Hemorrhagic bleeding disorder
  • Heart disease

Moreover, some people may have allergic reactions to the adhesive electrode pads that TENS medical devices employ. Therefore, TENS therapy may not be for exactly everyone. However, with the advancement of innovation and technology, the iTENS wireless unit at iTENS Australia has taken pain relief via TENS to a new level.


The Revolutionary iTENS Wireless Unit at iTENS Australia

The iTENS is where convenience and technology meet to improve quality of life. It is a modern-day electrotherapy device that merges wearable technology with a TENS machine’s efficient and lasting pain relief. Moreover, it is the world’s first FDA-cleared, true wireless TENS medical device on the market. Having FDA clearance ensures users that the machine they are using has passed the necessary testing and verifications for it to be a safe medical device. It also means that you are no longer required to have a medical prescription in order to purchase this over-the-counter, drug-free way to combat pain. 

Furthermore, the iTENS unit is entirely wireless and easy to use. You can access the parameter settings using your iOS or Android smartphone through the iTENS app via Bluetooth connection. Alternatively, you can also activate the device manually in the device itself if you wish to do so. With the iTENS, the days of wired and bulky TENS medical devices are truly in the past.

In addition, the adhesive electrode pads that the iTENS uses are hypoallergenic. Thus, allergic reactions and skin irritations are less likely to occur with using the iTENS wireless unit. The electrode pads are also innovatively designed with a unique butterfly wing-like shape to increase flexibility and comfort for seamless pain management treatment.


The iTENS TENS medical device is compact, portable and easy to access; you can use them at home and while doing regular activities. You may wear it on the go by simply slipping it into a pocket or attaching it to a belt as you go. The iTENS wireless unit is affordable as well as being cost-efficient. You do not need the use of any pain killers or other medications that could lead to adverse effects. Lastly, it can also give you more freedom of movement over your pain management treatment sessions that traditional wired TENS machines otherwise could not provide.


The innovative iTENS wireless TENS medical device can definitely benefit users, whether for professional or personal use. Healthcare experts and civilians can provide effective pain relief with increased efficiency and comfort. It can easily offer pain therapy with tailored settings for various pain and fatigue in specific body regions. You will discover everything about how your body responds to different degrees and patterns of stimulation as you continue to use it. It will enable you to function at your best while saving time and money.

However, if still unsure, it may be beneficial to visit a healthcare professional to obtain an expert opinion on the therapeutic medication regimen most suitable for you using a TENS medical device. You may learn about the proper pad placement of the electrode pads for your specific pain conditions.
