Transcutaneous Electrical Nerve Stimulation (TENS) is a helpful tool for the treatment of groin pain. To operate a TENS machine for groin pain, one should start by ensuring the skin is clean and dry. Then, carefully place the electrodes on the affected area, ensuring they are secure. Next, adjust the settings on the machine, such as the intensity and frequency, to a comfortable level. This will help provide pain relief for groin pain.

The prevalence of sports-related groin pain is high. However, anyone can be at risk of groin injuries. The symptoms include pain in the abdomen and upper thigh. People often use medications or conservative interventions such as abdominal exercises and balance training programs for prevention. Alternatively, they may utilise TENS therapy. This article will present a TENS device for groin pain, including its mechanism of action, proper operation, and safety precautions.

How a TENS Machine for Groin Pain Works

Groin pain refers to discomfort or pain in the area where the abdomen meets the thigh. It can be caused by a variety of reasons, including muscle strains, hernias, and injuries from physical training. Groin pain can range from acute to chronic pain conditions. Therefore, finding effective ways to manage and alleviate the symptoms is essential.

A TENS machine for groin pain is a portable, battery-operated device. It can provide pain relief by sending low-voltage electrical currents to the affected area. The machine works by blocking the transmission of pain messages to the brain. It effectively reduces the sensation of pain in the groin muscles. The electrical stimulation from the TENS machine also helps to relax the muscles and increase blood flow to the area.

Moreover, TENS can trigger the release of endorphins, which are the natural painkillers of the body. Endorphins help to alleviate pain and promote a sense of well-being, providing further relief for individuals with groin pain. TENS machines can be particularly beneficial for athletes with groin pain due to training or competition.

Benefits of Using TENS

  • TENS is a non-invasive treatment program for groin strain. It does not require any surgical intervention.
  • It provides pain-relieving effects without the need for medication, reducing the risk of harmful effects from drugs.
  • Electronic devices are portable, allowing users to continue with their daily activities while using the device.
  • People can use TENS in conjunction with other treatment methods. These include physical therapy, passive stretching, active strengthening programs, ice packs, laser therapy, and therapeutic exercise.
  • The therapy can be used for other pain conditions such as period pain, musculoskeletal pain, thigh pain, arthritis, disc injuries and others.

How to Operate a TENS Machine for Groin Pain

TENS machine for groin pain is effective, particularly in cases of mild pain or when aiming to enhance muscular function. To use a TENS unit, first place the electrode pads on the affected area. The skin should be dry and clean. Then, turn on the device and set the parameters to the desired levels.

It is crucial to adjust the frequency and intensity settings to find the optimal level of relief and hypoalgesic effects. It may vary depending on the severity of the groin strain injury. The frequency refers to the number of electrical pulses delivered per second. Meanwhile, the intensity refers to the strength or power of the electrical pulses.

The treatment duration may last for 30 to 45 minutes. It is also recommended to use the TENS unit several times per week for the best results. After the sessions, users should turn off the TENS unit and remove the electrodes. They should also clean the adhesives before storing them in a cool and dry place. Doing so may extend the use of the pads.

Pad Placement for Effective Relief

To treat groin pain, particularly common as an injury in athletes, the correct placement of TENS pads is crucial. Place the electrode pads on the skin surrounding the affected area. For groin injury management, position one pad where the abdomen creases into the leg and the other on top of the inner thigh or adductor muscle.

It is important to avoid placing pads directly on sensitive areas or over muscle atrophy if present. Overall, TENS helps in managing the constant pain, aiding in normal function and recovery. It also plays a role in the prevention of groin pain.

Safety Precautions When Using a TENS Machine for Groin Pain

When using a TENS machine for groin pain, it is important to take certain safety precautions. Firstly, it is crucial to consult a healthcare professional before using the TENS machine, especially for chronic pain treatment. They can guide the appropriate settings and limits of pain that should be used.

Secondly, individuals with acute groin injuries, such as athletes, should refrain from using the TENS machine immediately after the injury. It is advisable to wait until the initial inflammation has subsided and the individual has stopped training. This can prevent potential exacerbation of the injury.

Lastly, it is important to be cautious when placing the electrodes of the TENS machine near areas of injury, broken skin, or soft tissue injuries. Improper placement can result in electrical nerve stimulation modalities causing discomfort or potentially worsening the injury. Always follow the recommended guidelines for electrode placement to avoid any loss of function or complications associated with the injury type. Overall, these safety precautions are necessary to ensure the effective use of a TENS machine.

Potential Side Effects

The TENS treatment program has the potential for muscle spasms to occur as a side effect. The electrical stimulation from the electronic device can sometimes cause the muscles to contract excessively. Users need to start with the lowest setting and gradually increase the intensity to avoid muscle spasms.

In rare cases, skin irritation may occur. The adhesive pads can sometimes cause irritation, redness, or even blisters in some individuals. This can be exacerbated by leaving the pads on for too long or using them at too high of an intensity. Therefore, users need to discontinue use and consult a healthcare professional for alternative options.


In conclusion, using a TENS machine for groin pain can be a practical and non-invasive method for managing discomfort. By placing electrode pads on the affected area and adjusting the frequency and intensity, users can find significant relief. Regular sessions, lasting about 30 to 45 minutes, are recommended for optimal results. Proper maintenance of the machine and electrodes ensures longer usability and effectiveness in treating groin pain, especially for athletes and individuals with mild to moderate pain.

TENS therapy requires careful consideration of safety measures. Consulting a healthcare professional for guidance on settings and limits is crucial. Those with acute injuries should wait until the inflammation subsides before using the device to avoid potential harm. Proper electrode placement is vital to prevent discomfort or worsening of injuries. Users should start with the lowest intensity to avoid muscle spasms and be mindful of potential skin irritation. Overall, adhering to safety guidelines ensures effective and safe TENS machine use.
