Strong TENS Unit – Understanding the Frequencies, How to Use the Device, and Price Guide

A wireless pain relief from iTENS with accessories

Pain management methods are crucial to alleviating aches. One such option is a Transcutaneous Electrical Nerve Stimulation or strong TENS unit. It is a medical device that delivers electrical impulses to stimulate the nerves. The device can deliver Low-Frequency (LF) and High-Frequency (HF) stimulation. The device is straightforward, involving putting the electrode pad on the pain area and adjusting the settings. TENS units are available at prices ranging from $50 to $500 or more.

Living with chronic or acute pain can significantly impact daily life and overall well-being. Traditional pain management methods may not always provide relief. Thus, it leads many individuals to explore alternative options. Fortunately, electric nerve stimulation can be effective in providing pain relief, similar to seeing a physical therapist. This article will present the frequency and levels of intensity of TENS, how to use the machine and the price of the unit.

Strong TENS Unit – Understanding the Frequency and Levels of Intensity

When it comes to a strong TENS unit, recognising the frequency and intensity is essential for optimal use. The frequency refers to the number of electrical pulses delivered per second, usually in Hertz (Hz). On the other hand, the intensity determines the strength or power of the electrical impulses, which is usually in Milliamperes (mA).

higher frequency produces more rapid and continuous pulses, usually above 50 Hz. In contrast, a lower frequency delivers slower and more intermittent currents, commonly below 10 Hz. The choice of frequency largely depends on the type and location of pain. For instance, a strong frequency works to activate the pain gate mechanism. This provides ease by blocking pain signals, which is vital for acute pain conditions.

Moreover, a strong TENS device offers adjustable intensity levels, allowing for more powerful electrical stimulation. For higher intensity settings, the mA can typically range from 10 to 50 mA or more. As such, for lower programs, the intensity can typically start from 1mA to 10mA. Nevertheless, it is vital to increase the settings gradually. This helps people to find the most effective electric stimulation without causing discomfort.

Conditions that Can Benefit from Using the Device

The following are the kinds of pain that can benefit from a strong electrical device:

  • Acute pain – high-frequency TENS are helpful in managing sudden pain. This includes labour painsports injuriesmenstrual cramps, or other short-term conditions.
  • Chronic pain conditions – a strong TENS can also alleviate long-term aches. These conditions are neck painphantom painstump pain, backaches, and osteoarthritis pain.
  • Muscle spasms and tension – TENS can ease ongoing pain in muscles due to wear and tear, overuse, and other factors.
  • Neuropathic pain – certain conditions that involve the nerves, such as peripheral neuropathy or sciatica.

How to Use a Strong TENS Unit

Using a strong TENS unit properly is crucial to maximise its benefits and ensure a safe and effective treatment program. Before using a TENS device, it is important to consult a medical professional. These practitioners can assess the condition and provide guidance on how to use TENS in the pain management routine.

Consequently, ensure that the device is off before starting. Depending on the model, the device may utilise disposable batteries or a rechargeable lithium battery. Then, determine the pain area and clean the skin before applying the electrode pads. Take the electrode patches, peel off the protective backing and gently place it on the skin. Also, it is crucial to know the correct electrode placement.

Turn on the device and adjust the setting according to specific needs or based on the recommendations of the health professional. This includes the frequency, intensity, and duration. Some devices also have pre-set programs for convenient use. Then, start the treatment. Note that the advisable therapeutic duration is 15 to 30 minutes. During the session, keep an eye on how the body responds to the treatment.

Safety Precautions

The electrical nerve stimulation is safe; however, safety measures are important to prevent risks. If a person has a serious medical condition, it is vital to consult a healthcare provider before using the device. Moreover, do not use the machine in or near sensitive areas. This includes the eyes, mouth, chest, throat, and bony regions.

Additionally, do not put the electrode patches on broken skin or open wounds. This can interfere with the natural healing process of such conditions. Avoid using the tool while driving, sleeping, or operating machinery. The stimulation can cause distraction or interference, compromising safety.

Price of a Strong TENS Unit Contributing Factors to Cost

Generally, the device is available at prices ranging from $50 to $500 or more. As such, there is a suitable device within a specific budget. However, the price of a strong TENS unit depends on various factors. Firstly, the brand and quality of the tool. Well-known brands have a record of producing reliable and durable devices, which often come with a higher price.

Secondly, different TENS equipment have various features and functionalities. The more advanced and versatile the device, the higher the price. For instance, some devices have adjustable settings, stimulation modes, a combination of treatments, timers, wireless, or adjustable settings. Accordingly, a strong TENS device provides a higher electric current; thus, it often comes at a higher cost.

Also, the need for additional accessories and electrode patches can influence the pricing of the device. Some may include extra pads or other accessories, which may have a higher price. Accordingly, devices with longer warranty periods and reliable customer support may have a higher cost due to the added security and assistance offered by the manufacturer.

Where to Buy

The TENS device is available in various physical and online stores. For people opting to buy in-store, many medical supplies and pharmacies offer such tools. These stores give the advantage of hands-on experience, allowing customers to see and try out the product before making a purchase.

On the other hand, retailers like iTENS Australia, offer the device for people wanting to purchase online. This platform offers wireless and rechargeable units for more convenient use. Online retailers provide the convenience of purchasing from the comfort of home. Also, it enables the buyers to check the reviews of the product and choose the most suitable device.


A strong TENS unit is a beneficial method for relieving various conditions, especially severe or acute pain. It uses high-frequency settings and higher intensity levels for a more effective treatment. The standard frequencies are above 50 Hz and have an intensity ranging from 10 to 50 mA or more. This is crucial in prompting the pain gate mechanism, which blocks the pain signals from reaching the brain. Nonetheless, it can also treat chronic pain conditions and other nerve-related aches.

The device is easy to use. It contributes to people needing an easy and accessible pain management routine. Users have to determine the pain area, clean the skin, place the electrode pads, activate the unit, and relax. Also, the device is available in price ranges that suit every need and budget. People can purchase it in a physical or online store, like iTENS Australia. Nevertheless, it is crucial to recognise the safety measures to ensure an effective and safe use.
