Transcutaneous Electrical Nerve Stimulation TENS Therapy: The Need to Know

A female news anchor reporting about TENS as a new faster pain relief

Transcutaneous Electrical Nerve Stimulation TENS therapy is a treatment that uses an electronic device to deliver electrical current as a method of pain relief. Accordingly, this electrical stimulation works based on different mechanisms. The electrical pulses can block pain signals, trigger the release of endorphins, and promote blood circulation. While TENS is safe, it is crucial to know the safety precautions. This may include consulting a health professional and following the proper electrode placement.

Acute pain and chronic pain affects millions of people worldwide. This reduces the quality of life and limits daily activities. Traditional pain management options often involve pain control medications or physical therapy, which may have side effects or do not provide adequate relief. This has led many individuals to seek out alternative pain relief methods, such as TENS treatment. The following sections will present TENS therapy, its mechanisms of action, and the safety precautions.

What is a Transcutaneous Electrical Nerve Stimulation TENS Therapy?

Transcutaneous Electrical Nerve Stimulation TENS therapy is a form of treatment that involves the use of an electrical device to send electric current to the body. Accordingly, pain clinics, healthcare professionals, and physical therapists usually use TENS as part of the treatment programs for their patients. Also, individuals can utilise TENS to treat different painful conditions.

TENS devices come in both wired and wireless forms. Wired TENS typically consists of a small unit connected to the electrode pads using lead cables. Meanwhile, wireless TENS does not require a physical connection between the control unit and the electrodes. This allows for greater freedom of movement. Nevertheless, both devices come with various features to optimise the stimulation for pain relief.

Furthermore, TENS offer a range of benefits. Foremost, it is a non-invasive and drug-free treatment. It does not require any surgical procedures, insertion of needles, or the use of over-the-counter medications. Also, TENS is cost-effective. It eliminates the ongoing cost of medical prescriptions or frequent visits to healthcare practitioners. Hence, TENS offers a more economically feasible option.

Conditions It Can Treat

TENS can treat the following types of pain:

  • Chronic pain conditions: TENS treatment is beneficial in managing conditions like arthritis pain, fibromyalgia, neck, shoulder, and backaches.
  • Acute conditions: TENS can alleviate discomfort resulting from primary dysmenorrhea, postoperative pain, labour pain, and tension headaches.
  • Musculoskeletal pain: this affects the muscles, bones, and joints. This includes conditions such as tendonitis, bursitis, rheumatoid arthritis, and osteoarthritis.
  • Neuropathic pain: this stems from damage or dysfunction of the nervous system. It involves ailments like diabetic neuropathy or sciatica.
  • Muscle discomfort: TENS treatment can effectively address muscular conditions, including muscle spasms, strain, and overuse injuries.

Mechanisms of Action in Transcutaneous Electrical Nerve Stimulation TENS Therapy

Transcutaneous Electrical Nerve Stimulation TENS therapy exerts its benefits through several mechanisms of action. One key mechanism involves the stimulation of the natural painkillers of the body, known as endorphins. The electrical energy from TENS can trigger the production and release of endorphins. Hence, it helps to reduce the perception of ailment and promote a sense of well-being.

Another crucial mechanism is the pain gate mechanism. According to this, the nervous system contains a “gate” that can open or close to allow pain signals to reach the brain. The electrical signals from TENS can influence this gate, effectively blocking the pain messages. By “closing the gate” through TENS treatment, individuals can experience relief from discomfort.

Accordingly, TENS has been shown to impact blood circulation in the treatment region. The electrical stimulation can promote vasodilation, which is the widening of blood vessels. This action facilitates the delivery of oxygen and nutrients to the body tissues. Nevertheless, this contributes to the reduction of inflammation and the promotion of tissue healing.

Understanding Low and High Frequencies

Low-Frequency (LF) TENS, typically set at frequencies below 10 Hz, is often described as providing opioid-mediated pain relief. Hence, it can stimulate the release of endorphins and enkephalins, which are the natural substances in the body. This frequency is beneficial for managing chronic conditions.

On the other hand, High-Frequency (HF) TENS is usually set at frequencies above 50 Hz. It is known for its ability to produce rapid relief during the stimulation period. Accordingly, this can stimulate and work based on the Gate Control Theory of Pain. This frequency is valuable for the treatment of acute conditions.

Safety Precautions When Undergoing Transcutaneous Electrical Nerve Stimulation TENS Therapy

When using Transcutaneous Electrical Nerve Stimulation TENS therapy, it is essential to observe certain safety precautions. Foremost, before undergoing TENS treatment, individuals should consult a healthcare professional. This is particularly important for people with underlying medical conditions. Accordingly, ensure that the TENS unit is in good condition, adequately charged, or has fresh batteries.

Before applying the electrode patches, the individual should inspect their skin for any cuts or open wounds. Also, do not position the electrodes on the head, mouth, eyes, throat, or chest. In applying the pads, make sure to follow the proper electrode placement. Moreover, avoid starting the TENS therapy with high settings. This can cause electrical shock and further discomfort.

During the treatment, it is vital to pay attention to how the electrical stimulation feels on the skin. If discomfort is experienced, stop the treatment and re-evaluate the placement or settings. Furthermore, avoid coming into contact with water while using the TENS unit. Water can interfere with the proper functioning of the device and may pose a safety risk.

Potential Side Effects

One possible side effect of TENS treatment is skin irritation at the site of the electrode placement. This may manifest as redness or rash. Hence, it is important to monitor the skin during and after the TENS session closely. Some individuals may experience muscle twitching or spasms. While this is relatively common, it should be monitored to ensure that it does not cause excessive discomfort.

In some cases, individuals may experience headaches or dizziness. If these symptoms persist or worsen, it is vital to discontinue the treatment and seek medical advice. Rarely, people may experience allergic reactions to the materials used in the adhesives.

Conclusion

In summary, Transcutaneous Electrical Nerve Stimulation TENS therapy is a beneficial treatment option for pain relief. It utilises a wired or wireless device to send electrical pulses to the body. Also, the device has various features and benefits. It is non-invasive, drug-free, and cost-effective. Accordingly, it works by blocking the pain signals, prompting the release of endorphins, and improving blood flow. Also, the electrical currents can stream in low and high frequencies.

With such mechanisms, TENS can help manage various conditions. This may include arthritis, backaches, primary dysmenorrhea, tension headaches, sciatica, tendonitis, and muscle spasms. Nevertheless, it is crucial to know the safety precautions. This may involve consulting a professional, checking the device, and following the proper pad placement. Also, it is vital to recognise the potential side effects of TENS treatment. Those who want to purchase TENS may check out the online retailer iTENS Australia.
