TENS Pain Relief: What Types of Pain Can It Treat?

A female newscaster reporting about iTENS

Transcutaneous Electrical Nerve Stimulation (TENS) is a type of therapy that can effectively treat various types of pain in adults. It works by blocking pain signals from reaching the brain and triggering endorphin release. It can alleviate musculoskeletal pain, which includes pain in the bones, joints, muscles, and tendons. Additionally, TENS pain relief is effective in reducing neuropathic pain, which is caused by nerve damage or dysfunction. It can also provide relief for muscle pain, such as soreness or tension.

Pain management can involve oral medications, physical exercise, and TENS therapy. Many people choose analgesics because they are easy to get and affordable. However, long-term use of medication carries the risk of developing unwanted side effects. As an alternative, some people turn to TENS machines for all-natural and non-toxic pain relief. This article will provide information about TENS, including how it works, the conditions it can treat, and the proper electrode placement.

How Does a TENS Pain Relief Work?

TENS pain relief works by sending electrical currents through electrode patches that people place on the skin surface. These currents elicit two general responses from the body, specifically the central nervous system. The first method is based on the Gate Control Theory of Pain. During TENS treatment, the pain gate mechanism in the spinal cord closes. Hence, it hinders the transmission of pain signals to the brain.

The second method involves triggering the production of endorphins. These chemicals have comparable effects to oral analgesics but without the potential risks of dependence or severe side effects. Endorphins bind to opioid receptors and inhibit them from sending pain messages. Moreover, they promote pleasure, reduce stress, and improve mood.

The use of a TENS machine has a positive impact on the circulatory system. The electric currents or mild vibrations boost blood circulation in the affected area. This helps to reduce inflammation, relax the muscles, and promote faster recovery of damaged tissues and nerve regeneration. Overall, these mechanisms make TENS machines a valuable tool in pain management.

Low and High Frequencies

  • The pulse rate or frequency of the stimulation is adjustable to suit different needs or preferences. Low-frequency TENS (10 Hz and below) has the effect of reducing nerve sensitivity. It is also the ideal setting to trigger the release of endorphins, which is beneficial for chronic pain conditions.
  • High-frequency TENS stimulation of the sensory nerves can effectively block pain. This has short pulses and intensity, often characterised by strong but comfortable sensations. It is a suitable setting for people with acute pain conditions. It also has an analgesic effect on activity-induced musculoskeletal pain and fatigue and increases mobility.

Conditions a TENS Pain Relief Can Treat

A TENS pain relief can manage a variety of conditions. Firstly, the sudden and short-term acute pain. TENS therapy can treat labour pain, period pain, sports injuries, and tension headaches. Secondly, TENS can address persistent and long-lasting chronic pain. Conditions such as arthritisfibromyalgia, shoulder, neck, and backaches can cause chronic discomfort, and TENS can provide relief.

Thirdly, the device is capable of managing musculoskeletal issues. This includes various conditions that affect the muscles, tendons, ligaments, and bones. It also encompasses strains, sprains, knee pain, and other musculoskeletal injuries. Fourthly, the unit can address neuropathic pain, which arises from damage to the nerves. This can cause sensations of burning, tingling, or shooting pain.

Furthermore, TENS can be beneficial in treating muscular pain, including soreness, tension, and overuse injuries. By delivering electrical pulses to the muscles, TENS can help reduce muscle discomfort and promote relaxation and recovery. Overall, by understanding the broad spectrum of conditions that TENS can address, individuals and health professionals can make informed decisions about the use of TENS.

Is It Safe and Effective?

TENS is generally safe when people use it properly. For instance, it is important to follow certain safety precautions. Before using the unit, it is essential to seek medical advice. This step is crucial for people with serious medical conditions. Also, it is vital to understand the user manual.

Moreover, people need to avoid placing the electrodes on areas with open wounds, cuts, rashes, or broken skin. It is also important not to apply the pads near or over the eyes, mouth, throat, chest, or bony regions. Furthermore, users should correctly place the pads. Incorrect positioning may result in ineffective treatment.

Electrode Placement and Pad Selection When Using a TENS Pain Relief

The exact electrode placement is essential to the effectiveness of the electrical stimulation therapy. For TENS pain relief, position electrodes on either side of the pain. It should be near the affected nerve to stimulate them optimally. For back pain, place the electrode pads on both sides of the spine or one side for localised pain.

To alleviate joint pain, place the TENS electrodes around the joints rather than inserting them directly. In addition, individuals can adjust the placement of the pad to find the most effective spot. To stimulate muscles, place the electrodes on the top of the muscle group. This will provide an even distribution of electrical impulses and produce contraction more efficiently.

It is important to note that overlapping electrodes should be avoided. It is advisable to maintain a one to two inches distance between each pad. Placing them too close may cause a burning sensation or skin irritation. In contrast, if the pads are too far apart, they may not stimulate the nerve endings sufficiently.

When to See a Medical Professional?

When using a TENS unit, it is necessary to be aware of when it is appropriate to seek medical assistance. This is to ensure correct usage and avoid any potential issues. Firstly, if a user experiences any adverse reactions such as skin irritation, such as redness, itching, or swelling.

Secondly, if there is severe discomfort during or after the session. Thirdly, if a person experiences symptoms like dizziness, nausea, headache, or changes in skin colour. These are the signs that it may be necessary to consult a medical professional. However, they are usually rare and unlikely to occur with proper use of the TENS unit.

Conclusion

In summary, TENS pain relief offers a versatile and effective solution for various pain-related conditions. From acute pains to chronic ailments, and even nerve-related discomfort, TENS therapy plays a crucial role in managing pain. In addition, its ability to enhance blood circulation and stimulate endorphin production aids in muscle relaxation and recovery. Consequently, TENS machines have become an invaluable tool in both home and clinical settings.

Proper electrode placement is crucial for effective TENS therapy. Users should position electrodes on either side of the pain, near affected nerves. Muscle stimulation requires placing electrodes on the top of the muscle group. Maintaining a one to two inches distance between pads is essential to avoid discomfort. If users experience adverse reactions or severe discomfort, consulting a medical professional is advised. Overall, following guidelines ensures the safe and effective use of TENS units for pain management.
