TENS Relief: A Complete Guide

Transcutaneous Electrical Nerve Stimulation (TENS) therapy is a drug-free and non-invasive method that alleviates pain by blocking pain signals in the nerves. It can also stimulate the release of endorphins, the natural painkillers of the body. To use a TENS unit, the person first cleans the area for treatment. They then place the electrodes on their skin. After turning on the unit, they adjust the settings of TENS for relief.

Living with pain can greatly affect the quality of life and limit daily activities. Many people turn to pain medications as a solution. However, these often come with unwanted side effects. Fortunately, people can use TENS devices as an alternative solution. These devices are available for personal use and can be purchased online or at local pharmacies. This article will provide information about TENS therapy for relief, including the science behind its effectiveness and its proper usage.

What is a TENS for Relief?

TENS for relief is a treatment method that uses a portable device that transmits mild electrical pulses to the body through electrode pads. It has a handheld control unit that allows users to modify the patterns of electrical stimulation. The electronic device then connects to adhesive electrodes, usually through wires. However, some modern units use Bluetooth technology to operate the device.

A wireless TENS machine is more compact and lightweight. It also eliminates the need for holding a remote control. This device type allows for more flexible movements or range of motion during the treatment. Hence, individuals can combine TENS with other methods like exercise, physical therapy, or acupuncture for pain relief.

The TENS electrodes are interchangeable in different sizes and shapes. This can help fit different areas of the body and deliver appropriate stimulation levels. Additionally, the pads stick firmly to the skin but do not penetrate or leave permanent marks. It is worth noting that TENS is not a cure for pain but only provides temporary relief.

Conditions It Can Address

  • Acute pain condition: it is sudden and intense pain that typically lasts for a short period. This includes postoperative pain, fractures, broken bones, labour pain, muscle sprain, and period pain.
  • Chronic pain condition: refers to ongoing pain that persists for over three months, even after the initial injury or illness has healed. These include sciatica, fibromyalgia, ankle tendonitis, osteoarthritis, frozen shoulder, tennis elbow, and bursitis.
  • Body aches: it can be a general feeling of soreness or localised pain in specific body areas. This includes wrists, elbows, back, shoulders, knees, ankles, hips, thighs, hands, or feet.

The Science Behind TENS for Relief

The science behind TENS for relief is through three key mechanisms. Firstly, the Gate Control Theory. It suggests that there are nerve fibres in the spinal cord that act as “gates” and control the transmission of pain signals. When external stimuli like electricity are provided, these neural gates restrict the pain signals travelling to the brain.

Secondly, TENS helps in releasing endorphins. These hormones have similar effects as oral analgesics but without the risks of dependence or harmful side effects. Endorphins bind to opioid receptors and inhibit them from sending pain messages. Moreover, they promote pleasure, reduce stress, and improve mood.

Lastly, TENS therapy can boost blood circulation in the treated area. Improved blood flow is crucial for healing and pain relief. When the electric currents from a TENS unit interact with the body, they encourage the blood vessels to expand. Hence, it brings more nutrients and oxygen to the affected area, which helps in reducing pain and speeding up the healing process.

Understanding Frequencies and Intensities

Frequency refers to the number of pulses or cycles of electrical current per second. The typical frequencies in TENS therapy range from 1 to 150 Hz. Lower frequencies, such as 1-5 Hz, are suitable for chronic pain relief. Meanwhile, higher frequencies, such as 80-150 Hz, are for acute pain.

Intensity is the strength or power of the electrical currents, measured in milliamps (mA). It influences how deeply the electrical signals penetrate the body. Generally, TENS therapy starts with a low intensity and gradually increases to a comfortable level. Finding the right intensity is essential for effective pain management.

How to Conduct TENS for Relief

TENS for relief is proven effective. However, it is important to operate it correctly to maximise its benefits and minimise potential risks. To begin using a TENS unit for muscle pain, locate the affected area and ensure that the skin is clean and dry. Consult the manual guide or a physical therapist for accurate electrode placement.

After determining the position of the electrode patches, place them directly on or near the pain site. It is crucial to securely attach them to prevent them from falling off during use. Many TENS machines offer adjustable intensity levels, pulse settings, and timer functions. Begin with a low intensity and gradually increase until there is a slight tingling feeling in the muscle. Constantly check for signs of skin irritation.

The average duration of stimulation for pain relief is 20-30 minutes. Once the session is complete, switch off and remove the electrode pads. Those with preexisting medical conditions or pregnant women must consult a healthcare provider before administering a therapy session to ensure safety and effectiveness.

Advantages of TENS Therapy

TENS therapy offers advantages to users. Firstly, it is a non-invasive and drug-free method of pain relief. It helps eliminate or minimise pain sensations or other discomforts without the need for medications. Secondly, it provides personalised pain relief through customisable programs. The device has adjustable settings, such as intensity, pulse rate or frequency, and pulse width or duration.

Thirdly, a TENS unit is portable and easy to use. It is more compact and lightweight compared to the electrotherapy machines in pain clinics. This makes it more convenient for individuals to manage their pain on the go, whether at work or during travel.

Conclusion

In conclusion, TENS for relief is a portable and versatile pain management method. It uses mild electrical pulses to alleviate acute and chronic pain conditions, as well as body aches. The science behind TENS involves the Gate Control Theory, endorphin release, and improved blood circulation. While TENS does not offer a permanent cure, it provides temporary relief. It is a safe and effective option for those seeking a non-invasive and drug-free method of relief.

Using a TENS device requires careful application. Begin by cleaning and drying the skin, placing electrodes accurately, and securing them to avoid displacement. Adjust the TENS machine settings, starting with low intensity and gradually increasing to a comfortable level. Understand the significance of frequencies and intensities to tailor the therapy. Moreover, regularly check for skin irritation and consult manuals or professionals for proper usage. Individuals interested in wireless TENS devices may check iTENS.
