Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive form of electrotherapy that provides effective relief from pain. Many people use this during physical therapy because it complements other treatments during rehabilitation. Some also wish to own personal devices for convenient use. Certain factors contribute to determining the best TENS unit muscle stimulator. This includes the device type, provided program modes, levels of frequency and intensity, and convenience and ease of use.

Wired and wireless TENS units are available for purchase without prescriptions. There are a variety of options available online or in pharmacies. Moreover, people may use these devices without medical supervision. By using different intensities and frequencies, TENS machines alleviate aches from various conditions. This article will present the factors to consider when searching for TENS, such as the program modes, device type, frequency and intensity levels, and convenience and ease of use.

Best TENS Unit Muscle Stimulator – Program Modes and Device Type

There are several factors to consider when looking for the best TENS unit muscle stimulator. These factors include program modes and device type. Generally, there are two types of TENS machines: wired and wireless. Wired TENS are also known as traditional or handheld TENS devices. These are commonly used in hospitals and therapy clinics. They use electrode cables to connect the controllers to the adhesive pads.

On the other hand, wireless TENS machines use Bluetooth technology to control the electric stimulation of the electrode pads. There are several advantages to using wireless machines. This is why many people use them in their homes and various places for convenient pain relief. By removing the restrictions of lead cables, people can be more comfortable during sessions.

Furthermore, many TENS machines offer preset modes as an additional feature for relieving pain. These modes have set frequency and pulse-width settings to suit different body parts and conditions. Burst mode delivers short pulses of electricity followed by a pause. Meanwhile, the continuous mode provides a steady stream of electrical stimulation at low frequencies. Lastly, the modulation mode combines high and low frequencies of electric currents.

Advantages of Using a Wireless Machine

There are several advantages to using a wireless machine. Here are some of them:

  • Portability: Wireless electrodes are easy to hide discreetly underneath clothing. This allows people to use the device in different places at any time.
  • Specialised electrode pads: There are more selections for wireless pads than wired pads. They come in various shapes and sizes. For example, the iTENS uses innovative wing-shaped electrodes.
  • Ease of use: Wireless TENS remove the hassle of connecting wires to the pads. This reduces the setup time of a session.
  • Cost-effectiveness: Those who use wireless machines do not have to check and replace wires once they develop breaks.

Best TENS Unit Muscle Stimulator – Frequency and Levels of Intensity

The best TENS unit muscle stimulator must offer a wide range of frequencies and levels of intensities. Typically, TENS machines have a frequency range of 1-150 Hz and an intensity range of 0-80 mA. Then, adjustable settings allow users to customise the settings for optimal pain relief. This makes the TENS a versatile device capable of addressing different types of pain.

Intensity levels determine the strength of the electrical currents. Meanwhile, frequency refers to the number of electrical pulses delivered per second. Finding the right combination of frequency and intensity settings can provide natural pain relief to the individual. For guidance, they may consult a medical professional regarding the regularity, duration, and settings for TENS therapy.

In addition, users may check the guidelines from the product manufacturer to understand how to use their device. Overusing these machines, especially in high frequencies, may have adverse effects. This may include skin irritation, muscle spasms, and mild burns. Furthermore, frequent use of high-frequency stimulation may lead to the development of tolerance to electric stimulation.

Understanding the High and Low Frequencies

High-frequency stimulation (50-120 Hz) triggers the spinal nerve cells to block pain signals from reaching the brain. This is the mechanism described in the Gate Control Theory of Pain. This process takes effect immediately or within 30 minutes of the session. It is suitable for acute pain conditions like sports injuries. In addition, it helps relieve sore muscles.

Meanwhile, low-frequency stimulation (2-10 Hz) triggers the production of endorphins. These hormones are natural painkillers that build up to relieve aches. This is ideal for chronic pain because its effects last hours after the session. Many use it for fibromyalgiaarthritis, and sciatica.

Best TENS Unit Muscle Stimulator – Convenience and Ease of Use

The best TENS unit muscle stimulator should offer features that enhance its convenience and ease of use. Many TENS machines have lightweight designs to increase their portability and convenience. In addition, they add user-friendly features such as rechargeable batteries and easy-to-navigate interfaces.

Many TENS machines are designed to be easy to use without medical supervision. To start, users must place the electrodes on or near the origin of the pain. Then, they may turn the machine on. It is best to start on low settings to avoid sudden shocks or discomfort. After that, they may gradually increase the settings or select a preset treatment mode.

TENS therapy sessions generally last between 20 to 30 minutes. However, people may also follow the advice of a healthcare professional regarding the duration. Once the time elapses, the user must turn the machine off. Then, they may remove the electrode pads and store them for future use. People may use TENS therapy daily up to four times while using low-frequency stimulation.

General Precautions When Using the Device

It is best to consult a healthcare professional before using electrotherapy devices. They can assess the compatibility of the device with the health condition of the individual. Generally, those with metal and electrical implants and a history of seizures, epilepsy, and heart disease should avoid using TENS.

Furthermore, proper electrode placement is crucial for effective pain relief. Users must avoid sensitive areas like the spinal cord, throat, chest, joints, and top of the head. They should also avoid placing pads on irritated, infected or broken skin. Lastly, people should refrain from using TENS near water to avoid possible electric shocks.

Conclusion

When looking for the best TENS unit muscle stimulator, people must consider various factors. The device type is a foremost factor. Some people may choose wired units while some prefer the convenience of wireless units. Another factor is the offered program modes. These add to the convenience of using TENS machines since they are tailored for different conditions. Moreover, a TENS machine must provide sufficient frequency and intensity levels with adjustable settings.

TENS machines use high and low frequencies to address different types of pain. It is effective for fibromyalgia, arthritis, sciatica, and sports injuries. However, it is best to consult a medical professional before using TENS therapy to ensure safety. Furthermore, they may use FDA-approved devices to ensure the quality and reliability of the device. One option is the wireless iTENS from iTENS Australia. It uses wing-shaped electrodes controlled by a smartphone app.
