Transcutaneous Electrical Nerve Stimulator for Pain Relief: What are the Treatable Conditions?

A female news anchor reporting about iTENS

Transcutaneous Electrical Nerve Stimulation (TENS) is a therapy that involves the use of low-voltage electrical currents to provide pain relief. Accordingly, this electrical stimulation blocks pain signals and triggers the release of endorphins. With such approaches, transcutaneous electrical nerve stimulators for pain relief can treat a wide range of conditions, whether acute pain or chronic pain conditions. It can help manage neuropathic pain, musculoskeletal pain, and muscular pain.

Pain is a widespread human experience, and individuals have been utilising different methods of pain relief. The search for effective pain management methods includes painkilling medications and physical therapies. Fortunately, the development of TENS devices extends a promising alternative. Medical professionals, pain clinics, healthcare providers, and individuals often use TENS to treat different types of pain. This article will present TENS for pain relief, including its mechanism of action, treatable conditions, and proper usage.

Mechanisms of Action When Using a Transcutaneous Electrical Nerve Stimulator for Pain Relief

A transcutaneous electrical nerve stimulator for pain relief is a tool that sends low-voltage electric currents to the body. This is possible due to the electrode pads placed on the skin. Accordingly, pain clinics, healthcare professionals, and physical therapists often use TENS as part of their treatment options for patients. Also, individuals use TENS for personal pain control at home.

One of the ways in which TENS help reduce pain in adults is the use of high-frequency stimulation to block pain signals. This is based on the Gate Control Theory of Pain, wherein electrical pulses induce certain nerve fibres in the spinal cord to hinder the transmission of pain signals to the brain. Hence, it can provide short-term relief from discomfort.

Another mechanism of action of TENS is promoting the release of endorphins through low frequencies. They are natural painkillers that can help reduce stress and improve mood. Endorphins are neurotransmitters that inhibit the nerve cells from releasing pain messages. Overall, these mechanisms contribute to the pain-relieving effects of TENS.

Benefits of Electrotherapy

  • Electrotherapy relieves various acute and chronic pain conditions.
  • It offers a pain management solution without surgery or medication.
  • Most electrotherapy devices are small and easy to carry, allowing users to manage pain on the go.
  • Users can adjust pulse rate, pulse duration, and pulse amplitude to suit their comfort level and target specific areas of pain.
  • Electrotherapy does not carry the risk of side effects or dependency associated with pain medications.
  • By reducing pain, electrotherapy can help individuals move more freely and comfortably.
  • Electrical stimulation may improve blood flow, aiding in healing.
  • People can administer electrotherapy at home or on the go.

Treatable Conditions When Using a Transcutaneous Electrical Nerve Stimulator for Pain Relief

A transcutaneous electrical nerve stimulator for pain relief is a versatile tool for managing a wide array of painful conditions. It provides an effective means of aiding chronic pain conditions. This may stem from ailments like arthritis, backaches, and neck pain. Accordingly, TENS therapy is beneficial for treating acute pain conditions. This may include period pain, labour pain, postoperative pain, tension headaches, and injuries.

TENS therapy is frequently used to treat musculoskeletal pain. This includes a range of conditions, including osteoarthritis pain, joint pain, and rheumatoid arthritis. Furthermore, TENS is a valuable tool for people grappling with neuropathic pain. This includes conditions like sciatica, diabetic neuropathy, post-herpetic neuralgia, and other forms of nerve-related discomfort.

In addition, TENS treatment is effective for managing various forms of muscular pain. This involves tension-related discomfort, overuse injuries, and muscle soreness. TENS machines aid in relaxing muscle tissues, reducing soreness, and promoting muscle recovery. Nevertheless, it is crucial to know the treatable conditions to assist individuals in making an informed decision.

Is It Safe?

TENS is generally safe. However, there are some safety precautions to consider. Firstly, avoid electrode placement on sensitive areas. This may include the temples, head, front and sides of the neck, chest, and spinal column. Secondly, it is important to familiarise the functions of the device. Stay within the recommended settings and avoid extreme intensity levels.

Thirdly, do not use the TENS machine while sleeping, driving, or operating heavy machinery. It is essential to remain alert and focused during the treatment. Lastly, since they are electrical devices, do not use the unit in water to avoid shocks.

How to Operate a Transcutaneous Electrical Nerve Stimulator for Pain Relief

Operating a transcutaneous electrical nerve stimulator for pain relief involves several key steps. Begin by checking the condition of the device. Make sure that the unit is adequately charged or has fresh batteries. Then, attach the electrode patches to the central unit using the lead cables. For wireless TENS devices, connect it to a smartphone or tablet via Bluetooth. After that, locate the treatment areas and prepare the skin.

The next step is to place the adhesive electrode pads. It is essential to refer to the pad placement guide to determine the appropriate positioning. Once the pads are in place, power on the TENS unit. The device may allow users to adjust the settings or choose a pre-set program. Nevertheless, it is vital to start with the lowest setting and gradually increase it to a comfortable intensity and frequency.

While the TENS device is in operation, it is essential to closely monitor the response of the body to the electric stimulation. The session duration is typically around 30 minutes. Once the TENS therapy is complete, power off the machine and gently remove the electrode pads from the skin.

Pad Placement Guide

Correct electrode placement is essential for optimal pain relief. Generally, the pads should be on both sides of the pain to allow the electrical impulses to flow towards the centre. For back pain, place the electrode pads on either side of the spinal cord. For muscle pain, one may put the electrodes directly on the affected muscles.

To address joint pain, such as knee osteoarthritis, it is necessary to place a pad above and below the knee joint. The same applies to shoulder pain, elbow pain, and ankle pain. However, adjustments may be necessary depending on the specific location.

Conclusion

In conclusion, a transcutaneous electrical nerve stimulator for pain relief works by blocking pain signals and releasing natural painkillers like endorphins. It is useful for managing various conditions such as arthritis, backaches, and nerve-related discomfort. TENS therapy also helps with acute pain like period pain and postoperative discomfort. Moreover, it is beneficial for musculoskeletal pain, including joint and muscle soreness. Hence, TENS offers a versatile and effective option for pain relief, promoting relaxation and enhancing recovery.

Operating a TENS unit involves checking the device, attaching electrode pads, and placing them correctly using a guide. Start with the lowest settings and adjust gradually for comfort. During the session, monitor body response closely. For back pain, position pads on both sides of the spine; for muscle pain, place them directly on affected muscles. To address joint pain, like knee or shoulder, position pads above and below the joint. After the session, power off and remove the pads gently.
