TENS for Muscle Pain: Purpose and Benefits

A newscaster reporting about TENS as a new pain relief

Physical therapists and other health professionals utilise Transcutaneous Electrical Nerve Stimulation (TENS) as a natural method of pain relief. It can help alleviate various acute and chronic pain conditions. In particular, it can reduce muscular discomfort. The purpose of TENS for muscle pain is to target specific body areas that are tense or sore. Then, it stimulates the nerves to lessen pain signals sent to the brain. Consequently, users receive relief without medication. Also, it improves blood circulation, accelerating healing.

Individuals who want to experience TENS therapy can visit hospitals or pain clinics. Moreover, they can buy a personal TENS electronic device to access a pain reliever immediately, anytime and anywhere. They can obtain one from online or physical stores nationwide. Nevertheless, they must understand the elements of electrical nerve stimulation to make informed decisions. Thus, the article will present the purpose of TENS for muscular aches and discomfort, its benefits, and how to apply it.

Purpose of TENS for Muscle Pain

The purpose of TENS for muscle pain is to provide relief from discomfort. Also, it aims to help manage pain naturally. Hence, it utilises an electrical device that emits low-voltage electrical pulses. The electrical currents target sore and tense muscles and nerves to stop pain messages from reaching the brain. As a result, there is a numbing sensation that can help alleviate muscular pain.

Electrical nerve stimulation also promotes the release of endorphins. Endorphins are natural pain-relieving chemicals the body produces. Their role is to lessen discomfort further. Also, the purpose of TENS in increasing endorphin levels is to provide relaxation since these chemicals are known to produce feelings of euphoria and reduce stress. Thus, people can experience physical and emotional relief.

Some TENS machines are combo units. They have TENS and Electronic Muscle Stimulation (EMS) functionalities. EMS sends electrical impulses to contract the muscles, which can help improve blood circulation and reduce stiffness. This combination of TENS and EMS can provide a more comprehensive approach to reducing the pain intensity of acute and chronic conditions.

Brief History of TENS Therapy

  • TENS pain relief therapy was developed in the early 1970s.
  • C. Norman Shealy, a neurologist, initially used TENS to explore the uses of electrical stimulation.
  • In the 1980s, TENS therapy gained popularity as a non-pharmacological pain relief method.
  • Medical professionals in physical therapy, chiropractic, and pain management clinics have utilised TENS.
  • Researchers found TENS effective in managing various types of pain. These include nerve pain and musculoskeletal pain.
  • The TENS devices have become more portable and user-friendly due to technological advancements, allowing individuals to self-administer the therapy at home.
  • TENS Therapy continues to evolve, with ongoing research exploring its potential benefits in various painful conditions.

Benefits of Using TENS for Muscle Pain

Using TENS for muscle pain provides numerous benefits. TENS is a drug-free and non-invasive therapy. Hence, this makes it an excellent alternative to traditional pain medications. Drugs can have undesirable side effects, such as drowsiness or potential addiction. Also, TENS does not require people to insert needles, which can be a relief for those who are uncomfortable with this method.

In addition, individuals can administer electrical nerve stimulation using multiple sets of electrode pads. Thus, TENS can help those with musculoskeletal pain. Similarly, TENS offers versatility. Aside from muscular pain, it can alleviate other types of pain in adults. Some examples are acute pain conditions like sports injuries. It can also manage chronic pain conditions like cancer pain. Moreover, TENS can reduce knee joint pain, neck pain, and neuropathic pain.

Furthermore, TENS can improve blood circulation. The electrical pulses stimulate blood flow to the affected area, helping deliver essential nutrients and oxygen to muscles and tissues. Then, it reduces inflammation and accelerates the healing process. The TENS device is also user-friendly and portable. Therefore, people can operate it without physical therapists or doctors.

Is It Safe and Effective?

TENS is generally safe to use. Even pregnant women can administer the therapy for labour pain. However, individuals must consult a healthcare provider beforehand. The reason is that TENS may not be suitable for some. These may include those with conditions such as epilepsy or heart problems.

In terms of effectiveness, TENS has shown promising results in managing muscle pain. Studies have demonstrated its ability to provide immediate and short-term relief. Electrical stimulation utilises electrical pulses to disrupt pain signals and reduce muscle spasms. Users can utilise the different settings and pre-set modes for optimal outcomes.

How to Apply TENS for Muscle Pain

Applying TENS for muscle pain is simple. Users must begin by cleaning the skin surface of the pain site. Then, they must choose electrode pads proportionate to the size of the area. Afterwards, they can place the electrode patches. Those using multiple pads should space them out evenly to ensure proper coverage. Once they are in place, people can turn the TENS machine on.

Individuals should adjust the TENS unit settings according to their pain level and preference. As the treatment progresses, they must enjoy the positive effects of TENS. However, they should remember that TENS therapy should not cause discomfort or pain. They can lower the intensity or try a different setting if the sensation is too intense.

Take note of the recommended treatment time, usually 20 to 30 minutes per session. People can administer TENS multiple times per day. Nevertheless, they should wait a few hours between each session to allow their body to rest. Also, they must never sleep with the TENS unit on or use it in water. When the therapy is over, turn off the TENS unit and remove the electrode patches.

Pad Placement

People should ensure correct TENS electrode placement to maximise the benefits of the natural method of pain relief. They must attach the pads on either side of the painful area for general muscle pain. They should position them symmetrically for balanced stimulation. However, they must avoid areas with skin irritation.

Using smaller electrode patches for precise placement can be beneficial for targeting smaller muscle groups or pinpointing specific pain areas. Moreover, individuals can place the electrodes directly on or around the affected muscle. This allows for more focused stimulation, aiding in relieving muscle pain more effectively.


TENS for muscle pain is one of the natural forms of treatment. Its purpose is to relieve aches and discomfort naturally. Thus, it uses mild electrical currents to override pain signals sent to the brain. Also, TENS helps produce endorphins for relaxation. People relying on TENS can receive more benefits. They do not need to take drugs or use needles. Moreover, it improves circulation. Additionally, TENS can manage different conditions, including knee pain, sports injuries, and cancer pain.

Also, applying TENS is straightforward. First, it is essential to clean and dry the skin. Then, users should strategically place the electrode pads on or around the affected area. However, they should avoid pain sites with skin irritation. Afterwards, they can adjust the settings accordingly and enjoy the treatment session. It should only last for 20-30 minutes. Once done, turn the device off and remove the patches. With its user-friendly application, TENS is popular for individuals seeking pain relief.
