Menstrual pain can be debilitating. It leaves many women feeling in pain. Fortunately, Transcutaneous Electrical Nerve Stimulation or TENS period cramp relief machines exist. It is an electrical device that delivers electrical impulses to the body. Accordingly, it works based on the Gate Control Theory of Pain and Endorphin Release Theory. Furthermore, using the device is easy. Securely attach the adhesive electrodes to the treatment area. Then, turn on the period pain relief device and adjust the settings.

Painful periods are a common occurrence for many women. The contraction of the uterus often causes it. Nevertheless, it affects the overall quality of life. Traditional approaches to pain relief may include heating pads and medicines. However, they may not always be practical or have unwanted side effects. Conversely, TENS is a safe and effective alternative to pain relief. The following sections will present the TENS period cramp relief device, how it works, and how to operate it.

What is a TENS Period Cramps Relief Machine?

Menstrual period pain, or dysmenorrhoea, occurs when the muscles of the uterus contract to shed its lining. It can lead to discomfort, ranging from mild pain to severe pain. Accordingly, it is often experienced in the lower abdomen and lower back. Fortunately, the TENS period cramp relief machines can provide adequate pain relief. It is a device that sends electric pulses to the body via electrode patches attached to the skin.

Medical professionals, including physiotherapists and pain management specialists, commonly recommend TENS therapy. They suggest it to individuals seeking non-pharmacological options. It is particularly favoured by people who prefer to avoid harmful medicines. Nevertheless, individuals can undergo therapy at clinics or purchase one for home use.

TENS menstrual pain relief devices are available in wired and wireless models. Wired models connect the electrodes to the central machine via lead cables. On the other hand, wireless models provide a more discreet and portable solution. It allows users to wear the device under their clothing without the hassle of physical wires. They can control the unit manually or on a smartphone or tablet.

Causes of Menstrual Cramps

  • Prostaglandin Production: The body releases prostaglandins, which can cause the uterine muscles to contract. High levels of prostaglandins are associated with more severe cramps.
  • Uterine Fibroids: Noncancerous growths in the wall of the uterus can lead to increased painful cramps.
  • Endometriosis Pain: Occurs when tissue similar to the lining inside the uterus begins to grow outside, leading to severe period pain.
  • Adenomyosis: The tissue that lines the uterus grows into the muscular wall of the uterus.
  • Cervical Stenosis: In some women, the opening of the cervix is small or narrow. It can limit menstrual flow and increase pressure within the uterus, causing discomfort.

How a TENS Period Cramps Relief Machine Works

Foremost, the TENS period cramps relief machine leverages the Pain Gate Theory. According to this theory, the body has a neurological “gate” that controls the flow of pain signals to the brain. When the TENS unit emits electrical pulses, it effectively “closes” this gate. Thus, it blocks the transmission of pain signals to the brain. It significantly reduces the perception of menstrual cramps.

Secondly, the stimulation from the TENS device prompts the body to release endorphins. Endorphins are often offered as the natural painkillers of the body. They are hormones that interact with the opioid receptors in the brain and spinal cord. The increase in endorphin levels alleviates pain during periods. It also boosts mood, creating a sense of well-being.

In addition, the electrical impulses enhance blood flow to the targeted area. Improved circulation accelerates healing by delivering more oxygen and nutrients to the muscles and tissues. Accordingly, it aids in the removal of waste products and toxins. Nevertheless, this increased flow can help soothe and relax muscle spasms. It is a common symptom during menstrual periods.

Benefits of TENS Treatment

The non-invasive nature of TENS treatment stands out as a critical advantage. Unlike surgical procedures or interventions that require breaking the skin, a TENS unit operates externally. Subsequently, TENS therapy provides a drug-free alternative to pain management. It eliminates the side effects and dependency risks associated with pain medications.

Customisability is another significant benefit of TENS. Users can adjust the frequency, intensity, and duration of the electrical currents. It ensures that individuals can tailor the therapy to provide adequate relief. Additionally, TENS units are portable. It can be used at home, in the office, or travelling.

How to Operate a TENS Period Cramps Relief Machine

Operating a TENS period cramps relief machine involves a few straightforward steps. Begin by preparing the skin in the treatment region. Ensure the skin is clean and dry, providing an excellent adhesive surface. Accordingly, attach the electrode patches to the skin. It is crucial to know where to place the pads. Connect the electrodes to the machine via wires or to a smartphone via Bluetooth.

Once the pads are securely in place, the next step is to turn on the TENS machine. Initially, the device should be on its lowest settings. Then, carefully increase the intensity of the electrical impulses. The goal is to find a level that feels strong but comfortable without causing discomfort. As the session progresses, adjustments might be needed depending on how the pain diminishes or if the sensation changes.

The session typically lasts between 20 to 30 minutes. However, it can vary depending on recommendations. After completing the treatment session, turn off the TENS unit. Only then should one disconnect the pads from the skin. Following removal, storing the device and its components according to guidelines is advisable. It ensures longevity and hygiene.

Where to Place the Pads?

The pads typically go on the lower abdomen or back for period cramp relief. However, the placement may vary depending on where the pain is most intense. On the lower abdomen, place one pad on each side. It is approximately at the level of the hip bones. Avoid placing the pads directly over the belly button or too close together.

Position the pads on either side of the spine in the lower back area for back placement. This approach helps manage the pain radiating from the back during menstrual cycles. Do not place the electrodes directly on the spinal cord.


Overall, prostaglandin production, uterine fibroids, endometriosis, adenomyosis, and cervical stenosis are the common causes of menstrual cramps. Fortunately, the TENS period cramps relief machine is a highly effective tool for alleviating discomfort. It is a wired or wireless device that professionals commonly recommend. Accordingly, the device works by delivering electrical currents to the body via electrodes placed on the skin. It can block pain signals, trigger endorphin release, and enhance blood flow.

Furthermore, TENS therapy is non-invasive, drug-free, and customisable. The TENS units are also portable, enabling users to use them anytime. Moreover, TENS machines are easy to operate. One needs to clean the treatment area and attach the electrodes accordingly. Then, turn on the TENS device. Finally, adjust the settings. Begin at the lowest setting and gradually increase it to a comfortable level. The standard electrode placement for alleviating menstrual pain is in the lower abdomen and lower back.
