Transcutaneous Electrical Nerve Stimulation (TENS) is a method of pain relief that utilises electrical impulses. It was originally used by physical therapists and medical practitioners. However, advancement in technology led to the development of personal TENS machine, which is readily available for anyone to use. The electrical currents work by blocking the pain signals and triggering the release of endorphins. People can use the device by placing the electrodes on the target area and adjusting the settings.

The occurrence of chronic pain and acute pain can be debilitating and can impact the quality of life. While there are various pain management options available, some individuals prefer to avoid oral medications and their potential side effects. This is where the TENS medical device comes into play. The alternative for pain relief is beneficial for treating various medical conditions. This article will present TENS, including how it works and how to use it.

What is a Personal TENS Machine

A personal TENS machine is a small, portable device that delivers low-voltage electrical pulses to the nerves in the body. It is beneficial to people as they can use it in the comfort of their homes. This allows them to manage their pain issues on their own schedule without the need to travel to a clinic. Therefore, it is helpful for individuals with busy schedules or mobility limitations.

Accordingly, a TENS device is available in a wide range of options. The most common type of TENS has wires and is operated with disposable batteries. Meanwhile, there are TENS with wireless electrodes that have rechargeable battery functionalities. Users can control the pain relief therapy manually or with the use of a smartphone through Bluetooth technology.

Some TENS offer pre-set settings, which are predetermined treatments for a specific condition. This allows for a more direct approach or automatic therapy modes. Also, there are TENS with special modes, such as burst, continuous, or modulation. With such mechanisms, people can choose from different types and functionalities to suit specific needs.

Treatable Conditions

The following are the types of pain TENS can treat:

  • Acute pain conditions – this kind commonly comes from period pain, sports injuries, post-surgery aches, ankle pain, and headaches.
  • Chronic pain conditions – these are occurring and persistent pain. This may include neck pain, arthritis, fibromyalgia, and leg pain.
  • Nerve pain – TENS can be beneficial in treating nerve ailments such as diabetic neuropathy and sciatica.
  • Musculoskeletal pain – these are conditions like knee pain, joint ailments, or other forms of musculoskeletal discomfort.
  • Muscular pain – TENS can address sore muscles and tension. Whether it is from overexertion during physical activity or simply from the stresses of daily life.

How a Personal TENS Machine Works

The personal TENS machine is a type of treatment that works by using electrical stimulation to provide relief through various mechanisms. When an individual undergoes TENS therapy, the electric currents stimulate the nerves in the underlying skin. As a result, the body may respond by releasing endorphins. These are natural chemicals that act as pain-relieving substances.

Another way the TENS device works is by modulating the pain gate. The electrical impulses from the unit can interfere with the transmission of pain messages to the brain. This mechanism suggests that the sensation of pain can be reduced when non-painful input is given priority in the spinal cord over pain signals. Thus, it may close the gate to the transmission of pain messages.

Furthermore, the use of TENS can support the increase of blood circulation in the treatment area. The electrical pulses can help dilate blood vessels, leading to the improvement of blood flow. This mechanism serves to nourish the tissues and may aid in the removal of waste products. Therefore, it contributes to the reduction of discomfort.

Benefits of Using TENS

TENS therapy offers a range of benefits. One of the key advantages is that it provides non-medicated pain relief. This means that people can have pain management without having to rely solely on painkilling medications. Also, the treatment is non-invasive. It does not require the need for surgeries, injections, and other invasive procedures.

Additionally, the device is portable and easy to use. It allows people to carry the unit anywhere. The tool also has user-friendly controls for a more accessible treatment approach. Moreover, the TENS is cost-effective. It eliminates the cost of frequently visiting a clinic or a medical professional.

How to Use a Personal TENS Machine

Using a personal TENS machine involves several simple steps. Firstly, before using the device, ensure that the batteries are fully charged or replace them with fresh ones. Secondly, connect the electrodes to the unit using wires or through a smartphone via Bluetooth. Thirdly, remove the protective backing of the adhesive electrodes and place it in the treatment area.

Make sure the skin is clean and dry before applying the electrode pads to ensure good contact. Then, turn on the machine and adjust the stimulation. This may include setting the pulse durationintensity levels, and frequency. Accordingly, some TENS have preset programs and modes, thus, select the applicable ones for the specific condition.

Nevertheless, it is advisable to start the therapy with low settings and moderately increase it to a comfortable level. Once set, users can activate the stimulation and relax or continue with daily activities. After the session, turn off the device and carefully remove the electrode pads. Store the unit and its accessories in a safe place for future use.

Safety Guidelines When Operating the Device

Before undergoing TENS therapy, it is important to consult a medical professional. They can give guidance on whether the treatment is suitable. In placing the electrodes, make sure to avoid the sensitive areas of the body. This may include the eyes, head, throat, chest, or broken skin.

Avoid starting the therapy with a high setting to avoid electrical shock and discomfort. Do not use TENS while bathing or showering. Keep the unit dry at all times to prevent electrical malfunction. Additionally, avoid using TENS while engaging in activities that require full attention. The currents may cause a distraction that can affect the ability to focus.

Conclusion

A personal TENS machine is a valuable tool for managing different conditions. This is an effective treatment that allows people to take control of pain management in the comfort of home, work, or on the go. The therapy is safe as it sends low-level electrical impulses. Accordingly, these work with the principle of pain gate and the release of endorphins. As a result, it is beneficial for treating conditions like sports injuries, fibromyalgia, sciatica, knee pain, and muscle soreness.

The TENS unit also provides numerous benefits. It is non-medicinal, non-invasive, portable, and cost-effective. Additionally, the device is simple to use. Individuals need to identify the treatment area, place the adhesive electrodes, and adjust the settings. This approach contributes to the popularity of TENS. However, it is necessary to know the safety guidelines for optimal use. This may include consulting a doctor, following proper pad placement, and not using it for certain activities.
