TENS Stim: Definition, How It Works, and Benefits

A news report about TENS as a fast pain relief method

Transcutaneous Electrical Nerve Stimulation, or TENS stim, is a therapy that uses low-voltage electrical currents to relieve pain. A portable electrode machine is placed on the skin near the pain area to stimulate the underlying nerves. It causes the nervous system to block pain signals and release natural painkillers. Individuals can experience immediate pain relief and relaxation by using the TENS machine. It is suitable for various conditions, including chronic pain, postoperative pain, or muscle soreness.

Managing pain is essential for maintaining a good quality of life. TENS therapy is one of the natural or drug-free approaches to alleviate discomfort. It is common in clinical settings, such as pain clinics and physical therapy centres. However, TENS devices are also available for personal use. The following sections will thoroughly explain what TENS therapy is, how it relieves pain, and the benefits it can provide.

What is TENS Stim?

TENS stim is a therapy method that involves the application of electrical impulses to the body. This is done through a small, battery-operated device called a TENS machine. It has a control unit and sets of electrodes. The electrodes are placed on the skin near the area of pain. It allows the electrical pulses to stimulate the sensory nerves to relieve pain symptoms and other discomfort.

A TENS machine has adjustable settings to control the delivery patterns of electrical pulses. Different frequency and intensity levels can elicit specific responses from the body. However, the responses to the electrical stimulation can vary from person to person. Thus, trying different settings to find the most effective results is vital.

TENS units can be used at home or in a clinical setting. They are non-invasive and do not require the use of medication, making them a suitable alternative drug-free option. Additionally, TENS therapy is generally safe for most individuals, although it may not be recommended for specific medical conditions. Pregnant women and individuals with pacemakers, cancer, epilepsy, and heart illness should consult a health professional before using the device.

History of TENS Therapy

  • Electrical stimulation for pain management dates back to ancient times when electric fish were used to relieve pain.
  • Throughout the 16th to 18th centuries, electrical devices were invented to help treat various pain types and paralysis. However, they have limited settings.
  • The modern concept of TENS therapy was developed in the 1960s through the publication of Gate Control Theory by Ronald Melzack and Patrick Wall.
  • In 1974, Dr. Norman Shealy developed the first patient-wearable TENS unit.
  • Since then, TENS therapy has become an alternative method to treat various types of pain, including chronic back pain, arthritis, migraines, and musculoskeletal injuries.

How TENS Stim Works

The TENS stim machine sends mild electrical currents through the electrodes to the underlying nerves. According to the Gate Control Theory of Pain, the electrical pulses can override the nervous system. It also suggests that the nerves can carry limited sensory information at a time. Consequently, it disrupts the transmission of pain signals to the brain, resulting in lesser pain perception.

The stimulation also triggers the release of endorphins and other endogenous opioids. They are natural chemicals that bind to opioid receptors in the brain and other body parts. As a result, they help regulate pain and stress responses. Additionally, TENS also boosts blood circulation, helping to reduce inflammation in sore or injured areas.

These approaches provide temporary relief from pain. Users can adjust the pulse settings to suit their individual needs and comfort levels. Some people may feel immediate pain relief, while others may require several sessions to experience the full benefits of TENS therapy. Furthermore, proper electrode placement is vital to ensure optimal results.

Low and High Frequencies

TENS machines have programmable pulse rates or frequencies. A Low-Frequency (LF) stimulation operates at 2-10 Hz. It provides a mild tingling sensation that can induce the production of endorphins. It is also called acupuncture-like TENS. LF TENS is ideal for managing chronic pain conditions as it can provide long-lasting pain relief.

In contrast, High-Frequency (HF) stimulation operates at 80-120 Hz. It stimulates the sensory nerves to close the pain gate mechanism of the body. The stimulation level can be more effective for acute pain or severe pain symptoms. In addition to frequency, TENS devices also have adjustable pulse duration and pulse amplitudes or intensity levels.

The Benefits of TENS Stim

The use of TENS stim treatment has provided numerous benefits for people undergoing clinical or home pain management. One of its primary benefits is a safe pain relief option. Unlike medication or surgical interventions, TENS does not carry the potential side effects and risks associated with those methods. Thus, it is safe for long-term use.

Additionally, the customisable settings of the device allow individuals to personalise their treatment. It ensures the therapy can target different body areas and their pain levels. It is also easy to operate, and most units have pre-set modes. Moreover, having the device ready means people can use it anytime without needing to schedule an appointment with a healthcare provider.

Furthermore, TENS can provide immediate effects. Users can feel the electrical pulses work instantly. It can help to reduce the intensity of pain, relax the muscles, and improve the range of motion. Lastly, TENS devices, especially wireless ones, are comfortable and discreet to use. They do not hinder movement, allowing individuals to continue with their everyday activities.

Applications of TENS Treatment

TENS treatment is beneficial in various pain situations. Firstly, it is a standard treatment option in physical therapy. Health professionals use TENS to help patients manage chronic pain conditions. It includes ongoing pain like rheumatoid arthritis, sciatica, and fibromyalgia. Physical therapists can determine the appropriate settings and monitor the session.

Secondly, it is helpful in rehabilitation centres to help individuals cope with postoperative pain or sports injuries. It can be an adjunct therapy with other methods of pain relief. Finally, it is an effective pain management method during labour. Women can use it to combat the pain of contractions.

Conclusion

Overall, TENS stim is a safe, effective, and versatile tool for managing pain. It utilises a portable device to deliver mild electric currents to stimulate the nerves. This helps to block pain signals and release endorphins, providing natural relief. Additionally, it can help treat a wide range of pain conditions. It can provide immediate and targeted treatment without requiring drugs or invasive procedures. Therefore, it can be a suitable alternative for medications.

Understanding the TENS settings can help achieve effective results. TENS devices have user-friendly controls, allowing users to adjust the frequency and intensity levels easily. With its portable and convenient technology, TENS therapy enables individuals to take control of their pain management and improve their quality of life. Nevertheless, consulting with a health professional is essential to ensure safe and effective treatment. Individuals can purchase TENS machines, such as iTENS wireless, online at iTENS Australia.
