Portable Estim Unit: The Need To Know

Electrical Stimulation (E-stim) machines are sought after for their non-invasive form of electrotherapy. One example is the Transcutaneous Electrical Nerve Stimulation (TENS) machine. It provides pain relief for a variety of chronic and acute pain. Moreover, the wireless TENS devices are portable E-stim units convenient for home use. They can be used without medical supervision by following the guidelines provided by a healthcare professional or the device manufacturer.

Furthermore, it can be used by a variety of people. It is complementary to many forms of treatments. It is also an alternative to pain medication. Moreover, it helps improve blood flow and relaxes the muscles. These TENS devices are available for purchase online or in pharmacies. It is crucial to get a reliable device suited for their condition. This article will present how TENS machines work, how to use them, and the convenience of wireless TENS units.

Portable Estim Unit: How it Works

A TENS machine is an example of a portable E-stim unit suited for pain relief. This device uses low-voltage electrical currents to be delivered to the skin by electrode pads. These electrical stimulations trigger the natural processes of the body for relieving pain. It can treat chronic and acute pain using a wide range of settings. A TENS machine typically has a frequency range of 1-150 Hz and an intensity range of 0-80 mAmp.

Using high-frequency stimulation (50-120 Hz), the electric currents induce the spinal nerve cells to block pain signals from reaching the brain. This process is described as the Gate Control Theory of Pain. This stimulation is most suitable for acute pain. It alleviates pain within 30 minutes, and the effects last a few minutes after the session.

Meanwhile, low-frequency stimulation (2-10 Hz) triggers the production of endorphins. These painkilling hormones reduce pain and inflammation of the target area. Although the onset is slow, it is suitable for chronic pain since its effects can last hours.

Benefits of Using TENS Therapy

There are several benefits to using TENS therapy. Here are some of them:

  • Reduces or replaces intake of oral pain medication that has many adverse effects like stomach bleeding, headaches, and nausea.
  • Increases blood circulation to the targeted area.
  • Reduces inflammation and increases body mobility, which helps with rehabilitation.
  • Relaxes stressed muscles and reduces fatigue.
  • Boosts energy levels and helps the natural healing process.
  • Helps with fibromyalgiasciaticamigraines, and diabetic-related neuropathy.
  • Provides non-addictive pain relief and can be used up to four times a day.
  • Complementary to other treatments due to its non-invasive nature.

Portable Estim Unit: How to Use

Portable E-stim units like TENS machines are easy to use. They do not require medical supervision and people can use them at home. To start, the user must clean their skin with soap and water. Then, they can attach the electrodes on or near the pain area. Next, switch on the machine to its lowest settings. This is to avoid sudden shock or discomfort.

Afterwards, the user can gradually increase the settings to their ideal level for pain relief. A session usually lasts between 20 to 60 minutes. This depends on the condition or what the doctor prescribes to them. When the time has elapsed, turn off the machine, then remove the electrodes.

It is ideal to frequently clean the adhesives after using the device. It lengthens its longevity and is simple to do. Cleaning the adhesives requires a few drops of water and a clean cloth. Avoid using paper towels, as they can leave debris in the pads. Lastly, store the electrodes in a cool and dry place until future use.

Proper Pad Placement

Proper pad placement is crucial for effective pain relief using TENS machines. Ideally, pads are placed on areas near or on the origin of the pain. As an example, electrodes are placed on the trapezius muscles for headaches. Individuals may refer to the guidelines provided by the manufacturer. They may also consult a medical professional regarding their treatment.

Moreover, people should avoid sensitive areas when placing electrodes. These include the mouth, eyes, throat, chest, spine, joints, and top of the head. Additionally, abstain from putting adhesives on irritated, damaged, or infected skin. Lastly, do not put electrodes directly on varicose veins or numb areas.

Portable Estim Unit: Convenience of Wireless TENS

TENS machines are portable e-stim units available in wired and wireless options. Handheld units are often used in hospitals and rehabilitation centres, but some are available for home use. However, many people may benefit from using wireless TENS machines due to their convenience. Firstly, they remove the lead cables that restrict movement during therapy. This allows them to do simple tasks or be in more comfortable positions while using the machine.

Secondly, some wireless devices are controlled through smartphone applications. This removes the need to carry a separate device to operate the electrodes. Additionally, some can control more than one electrode pad at once. Thirdly, wireless electrode pads provide more options compared to wired pads. An example is the iTENS wing-shaped electrode pads that come in different sizes.

Lastly, wireless TENS devices often feature pre-set modes and user-friendly interfaces. These features make them more easy to use even when alone. Some also come with features like adjustable timers and backlit screens.

Pre-set modes

Another advantage of wireless TENS devices is the various options for pre-set modes. Although they still come with manually adjustable settings, pre-set modes provide more convenient pain relief. Some modes are tailored for specific body parts. Meanwhile, some are specific to various pain conditions. This reduces the need for input and experimentation of different settings.

Moreover, some devices offer massage modes to help relax the muscles. They may also provide muscle stimulation mode to target specific muscle groups. Thus, these modes increase the efficacy and efficiency of pain relief and muscle relaxation from TENS devices.


In conclusion, TENS machines are portable e-stim units for alleviating chronic and acute pain. They offer many benefits to their user by improving mobility, reducing inflammation, and relaxing muscles. Moreover, wireless TENS devices provide features that make them easy to carry around. The absence of lead wires allows users to do simple activities like reading during the therapy. Moreover, it removes the hassle of using a separate controller by incorporating the controls into a smartphone application.

Furthermore, these devices offer pre-set modes tailored to specific body parts. Some are also specific for different pain conditions. Lastly, they provide more options for electrode pads compared to handheld units. For those looking for wireless machines, iTENS from iTENS Australia may suit their needs. This device has all of the features mentioned above. Thus providing a convenient and portable method of pain relief.
