ProTens Machine vs iTENS: A Comparison Guide

iTENS small wings

Transcutaneous Electrical Nerve Stimulation (TENS) machines offer a swift and drug-free alternative for pain relief. Devices like the ProTens machine and iTENS help individuals manage acute and chronic pain. ProTens is a portable device with adjustable pulse settings connected to wired electrode pads. On the other hand, iTENS is a wireless TENS device with Bluetooth capability for seamless remote connection. Both devices use low-voltage electrical currents to stimulate the nerves.

Doctors or physical therapists may recommend TENS therapy for the treatment of chronic conditions or injuries. However, there are plenty of options in the market, and it can be challenging to determine the most suitable device. This comparison guide will help you determine which one can provide the best results for your specific needs. We will take a closer look at their settings, features, and maintenance guidelines. By examining these key factors, you will be able to make informed decisions.

ProTens Machine vs iTENS – TENS Settings

TENS machines utilise various parameters to activate the body’s pain-killing mechanisms. The ProTens machine and iTENS have adjustable pulse rates, pulse amplitude (intensity), and duration. In varying frequencies, it stimulates the nervous system to block pain signals from reaching the brain and releasing endorphins, the body’s natural painkillers. Moreover, pain relief depends on a person’s feedback and tolerance to the electrical stimulation.

ProTENS uses an asymmetrical bi-phasic square pulse waveform. This can be more useful in stimulating small muscle groups. It has an adjustable 0-80mA peak into a 500-ohm load for each channel. You can modify the settings by pressing the Mode buttons several times on the device.

Conversely, iTENS has three selectable waveforms, adjustable in manual modes. It includes the Symmetrical Biphasic Alternate Square, Asymmetrical Biphasic Alternate Square, and Monophasic Alternate Square waveforms. Each represents pulse delivery and affects neurons differently. Furthermore, the pulse frequency is adjustable through the smartphone app, while the intensity can be managed directly on the device and the app.

What TENS Can Treat

  • Neck pain: muscle stiffness, pinched nerves, arthritis, and facet joint pain.
  • Lower back pain: strain or injury to the back muscles or ligaments, nerve root compression, mechanical issues like spinal stenosis and herniated disc.
  • Shoulder pain: rotator cuff injuries, tendinitis, and bursitis.
  • Knee pain: bursitis, arthritis, torn ligaments, meniscus tear, chondromalacia patella or runner’s knee.
  • Hand/feet pain: arthritis, fibromyalgia, diabetic neuropathy, gout, tendinitis, carpal tunnel pain.
  • Pelvic or abdominal pain: menstrual cramps, endometriosis
  • Labour pain: intense contractions in the abdomen that may radiate to the lower back.
  • Postoperative pain: muscle soreness, swelling, and discomfort at the incision site.

ProTens Machine vs iTENS – Device Type and Features

TENS machines come in traditional forms with wired and wireless electrodes. The ProTens machine is a standard device connected to a handheld controller through lead cables. It has dual channels for up to four self-adhesive electrode placements over the painful area. Moreover, it features an inbuilt timer at 15, 30, and 60-minute duration. Hence, the stimulation will automatically stop after the pre-set time.

iTENS is a wireless TENS device with Bluetooth-capable electrodes. This allows remote connection to a smartphone app. In addition, iTENS has wing-shaped gel pads in small, large, and long sizes to suit different areas. The iTENS app features customisable settings and pre-set modes for convenient pain management. These programs have fixed settings based on body pain locations and health conditions.

Another essential factor to consider is the battery type. ProTens uses a 9v battery, while iTENS has a lithium-ion rechargeable battery. One full charge of iTENS has a total run time of 24 hours, depending on the intensity and treatment time. This eliminates the need to buy battery replacements, making the iTENS cost-efficient for long-term use.

Advantages of Wireless Units

Wireless TENS units offer several advantages compared to traditional TENS machines. Firstly, the wireless electrodes allow for greater mobility during the treatment. It does not restrict movement due to the length of wires, enabling you to move freely. This is beneficial for individuals who require pain relief on the go.

Secondly, it is more discreet and comfortable. It is more lightweight and easy to conceal under the clothes. Furthermore, the wireless iTENS enables faster pad placement since there is no need to attach wires before use. Lastly, managing pain relief is more convenient with the user-friendly interface of the smartphone app.

ProTens Machine vs iTENS – Device Maintenance and Safety Guidelines

Device maintenance is crucial towards efficient pain relief. It is important to inspect the device regularly for signs of damage or wear and tear. For the ProTens machine, it includes checking the wires for breakage and loose connections. If damage is detected, replace the affected parts with manufacturer-recommended replacements. TENS machine wires and electrodes are available in stores or online.

Meanwhile, iTENS requires cleaning after each use. Wipe the sticky surface of the pads with a damp cloth to remove the gel residue. This will help prolong the life of the pads. Additionally, proper cleaning and hygiene practices should be followed to prevent infections or skin irritations. It is also recommended to replace the electrodes when they lose their stickiness after several uses.

Moreover, do not use harsh chemicals or solvents to clean the device to prevent damage to the electrodes. Likewise, do not submerge or expose the TENS machine to water, as it may damage its internal components. Finally, store the device in a cool, dry place away from sunlight or extreme temperature.

When to Avoid TENS

TENS therapy is generally safe with minimal side effects. However, it is important to consult a medical professional to assess whether TENS is suitable for your condition. A TENS machine is not advisable for people with heart problems, epilepsy, cardiac pacemakers, or who are pregnant. Individuals with these conditions must seek clearance before using a device.

Since the device utilises electrical impulses, using TENS on surface areas with broken skin, open wounds, or infections is not advisable. In addition, do not use the device while sleeping, bathing, or driving. However, you may set an auto-off timer and promptly remove the pads before sleeping.


TENS therapy is one of the safest and most efficient methods of pain relief. The ProTens machine and iTENS are portable nerve stimulator units to help reduce pain without the risks of adverse side effects. Each device has distinct features to help make pain management efficient. For instance, the ProTens device has adjustable settings and preset time to help avoid overuse. On the other hand, the iTENS have wireless electrodes with Bluetooth connectivity for quick pain treatment.

In addition to the type of electrodes, you may also consider the battery type. Reliable battery life is crucial for adequate stimulation and pain relief. It is also important to note that TENS may not be suitable for individuals with serious medical conditions. Furthermore, regular maintenance is essential to preserve the life of the unit. All TENS machines require replacement electrodes when they lose their adhesiveness over time. With proper usage, you can manage pain effectively.
