Transcutaneous Electrical Nerve Stimulation Unit: What Conditions It Can Treat?

News feature about a new way to relieve pain

Transcutaneous Electrical Nerve Stimulation unit (TENS) is a portable electronic device that sends electrical current through electrode pads placed on the skin. This electrical stimulation works by blocking pain signals and triggering the release of endorphins. Accordingly, these mechanisms provide a drug-free method of pain relief for various types of pain. It can address whether acute pain or chronic pain. Also, it manages conditions like neuropathic painmusculoskeletal pain, and muscular ailments.

The field of medical technology is constantly evolving, and electrotherapy devices are a prime example of this progress. While there are many forms of pain relief, they may involve oral medications or invasive procedures. Thus, the development of TENS provides a unique and natural pain control over medical conditions. These small devices use electrical pulses to stimulate nerves and provide therapeutic benefits. This article will present how TENS works, the conditions it can treat, and how to operate it.

How a Transcutaneous Electrical Nerve Stimulation Unit Works

In general, a transcutaneous electrical nerve stimulation unit works by streaming electrical impulses to the body through electrode patches. This electrical stimulation functions based on different mechanisms. Firstly, TENS machines rely on the pain gate mechanism. The electric current from the unit travels faster than the pain messages and can close the gate.

TENS can block the pain signals from reaching the brain, reducing the perception of pain. Secondly, the electric nerve stimulation can also stimulate the release of endorphins. These are the natural chemicals of the body that act as natural painkillers. Endorphins can help reduce pain sensations, stress, and anxiety and promote an improved sense of well-being.

Moreover, the stimulation for pain relief can help improve blood circulation in the treatment area. The electrical currents can cause the blood vessels to dilate, providing more oxygen and nutrients to body tissues. Therefore, better blood flow can promote healing, reduce inflammation, and provide relief from numerous ailments. It also helps improve the range of motion.

Benefits of Using the Device Over Other Solutions

  • Targeted relief – TENS can specifically target the area experiencing discomfort, allowing for localised relief.
  • Non-invasive – it does not require any incisions, injections, or surgeries from healthcare providers.
  • Drug-free – this is beneficial for people who prefer to avoid oral medications or who wish to reduce reliance on painkillers.
  • Customisable settings – TENS offer modifiable settings, allowing users to adjust the pulse rate, intensity, and duration of the electrical pulses.
  • Portable and reusable – it offers the convenience of on-the-go pain management. Also, the reusable nature of TENS makes the treatment cost-effective over time.
  • Complementary therapy – people can integrate the treatment into other management plans like exercise or medications.

Conditions a Transcutaneous Electrical Nerve Stimulation Unit Can Treat

A transcutaneous electrical nerve stimulation unit can treat different types of pain. One is the persistent and long-lasting chronic pain conditions. This may result from ailments such as arthritis pain, fibromyalgia, shoulder, neck, and backaches. Accordingly, TENS can address sudden and temporary acute pain. It may include primary dysmenorrhoea, period pain, postoperative pain, labour pain, and headaches.

TENS therapy can also manage nerve-related conditions, such as sciatica or diabetic neuropathy. This type of ailment can cause burning, tingling, or shooting sensations along the affected nerve pathways. Also, it can help with musculoskeletal pain, which involves discomfort in the bones, ligaments, and tendons. Joint pain and knee osteoarthritis pain fall under this category.

Furthermore, TENS can provide relief to muscle pain. This can result from overuse, tension, or injury that can lead to soreness, stiffness, or spasms. TENS units can be applied directly to the muscles experiencing discomfort, delivering electrical pulses. This can help relax tense muscles, improve circulation, and decrease the sensation of muscle aches.

Are There Any Side Effects?

Using a TENS machine is generally safe, but there are some tolerable potential side effects to be aware of. The most common repercussion is skin irritation at the electrode placement site. This can happen if the electrodes are not placed properly or if the skin is sensitive to the adhesive material. Some people may also experience muscle twitching. Hence, it is vital to set the intensity at a comfortable level.

Additionally, using TENS for prolonged periods at high intensities may lead to muscle fatigue. Thus, it is important to follow the recommended guidelines for TENS usage.

How to Operate a Transcutaneous Electrical Nerve Stimulation Unit

Operating a transcutaneous electrical nerve stimulation unit involves a series of simple steps. Start by connecting the electrode to the machine using lead cables or to a smartphone via Bluetooth for wireless TENS. Then, free the treatment area from substances like dirt, oil, water, or lotion. This step is crucial to ensure the ability of the pads to stick to the skin.

Gently press the electrode pads onto the skin. Make sure that the pads are firmly attached and that they are at least one to two inches apart. Then, turn the unit on by pressing the power button or switch. Some TENS require people to adjust the settings. This may include modifying the frequency, intensity, and duration.

Some units may also allow users to choose from different types of pre-set programs and modes. Nevertheless, it is advisable to start with low settings and slowly increase it just to the comfort level. The duration of the therapy usually lasts for 15 to 30 minutes. Once the session is complete, switch off the unit and remove the pads.

Safety Guidelines

Before undergoing TENS therapy, it is vital to consult a health professional. They can provide guidance on whether TENS is suitable for the specific condition. In positioning the electrodes, do not place them on sensitive areas of the body, such as the eyes, head, mouth, throat, chest, or broken skin. Also, avoid setting the intensity too high. This can cause discomfort or further pain.

Take breaks for sessions longer than 30 minutes; prolonged use can lead to muscle fatigue. Additionally, do not use TENS while driving, operating machinery, or in contact with water. The electrical stimulation can interrupt focus, and water can cause shocks.

Conclusion

In conclusion, the transcutaneous electrical nerve stimulation unit is a valuable tool for pain management. It works by delivering electrical currents to the nerves beneath the skin through electrode pads. Accordingly, it functions by blocking pain signals from reaching the brain, promoting the release of endorphins, and increasing blood flow. These mechanisms are beneficial for treating conditions like backaches, period pain, diabetic neuropathy, knee osteoarthritis, and headaches.

TENS also offers numerous benefits. It provides targeted relief, it is non-invasive and drug-free, it has customisable settings, it is portable and reusable, and it can act as a complementary therapy. People can use TENS to alleviate their conditions with simple steps. Users will place the electrode pads, adjust the settings or choose from the pre-set programs and modes, and go on with the therapy. Nevertheless, knowing the safety guidelines and tolerable potential side effects of TENS is crucial.
