How to use a TENS units & EMS machines for period pain & abdominal cramps? Placement of electrode pads

Period pain is possibly the ailment that all women in the world suffer the most during their lives, it can be considered as part of their life cycle, and although many get used to it, it never ceases to be an almost unbearable discomfort in some circumstances.

Fortunately, electrotherapy can be a great ally to help you eradicate the pain caused by cramps, menstruation or any other cause that is generating such discomfort in the lower abdominal area. That is why today we are going to show you how to use it to make your ailments disappear.

How to use TENS machines to relieve menstrual or belly pain?

As you may have noticed, the ideal therapy to relieve menstrual pain is TENS, so here we will show you in detail its benefits and how to use it to stop feeling that strong pain that ruins the days of menstruation.

Benefits

  • Vasodilation: it will allow blood vessels to relax and dilate to allow more blood flow to the abdominal area, which will allow pain relief to be maintained even after your TENS session is over.
  • Increases pain threshold: one of its greatest benefits is that unlike drugs it does not create dependence, so as you use TENS you will become more and more tolerant to menstrual pain, to the point that you will feel it as a mild discomfort without having to be glued to your electrotherapy device.
  • Nerve and muscle relaxation: TENS is a healthy therapy for your nervous system as it strengthens it and helps it to relax, which will prevent other problems such as pinched nerves or neuropathies in the future.

What intensity to use?

One of the most important things to keep in mind to relieve your belly pain is the intensity of the current you should use. In this sense you have two options:

  • 10Hz to 30Hz: you get a mild stimulation that will allow a relaxation of the nerves in case you have a pain that is not so intense.
  • 40Hz to 80Hz: this is the frequency to use in case you have a very strong and intense pain that you cannot tolerate.

Electrodes for abdomen

Electrodes for abdomen
Electrodes for abdomen
  • Period pain: For menstrual pain, the electrodes are placed in the lower abdomen between the navel and the genital area, always prioritizing that the electrodes enclose the painful area.
  • Cramps: Cramps can be felt in any area of the abdomen, although they occur more regularly in the lateral sections. Whatever their position, what you should do is to enclose the area of pain between the electrodes. If you have 4, the ideal is to place them in a diamond shape surrounding the point of pain and if you have only 2, place them in the middle of both.

More types of EMS electrostimulators and TENS machines you should know

What are the causes of period pain?

Belly pain is undoubtedly one of the most common, especially in women, and although it is often attributed to a menstrual process, the truth is that it can have other causes that we will mention below.

  • Colic: these are an accumulation of air in some abdominal area, which causes discomfort that depending on the amount of accumulated gases may be of lesser or greater intensity.
  • Constipation: when eses accumulate for many days, they begin to generate pressure in the intestines that manifests itself as pain in the pelvic area. It is also very common for them to generate gas, which in turn causes cramping.
  • Menstruation: this female biological process is one of the most common causes of belly pain, which is generated by the so-called menstrual cramps that have their origin in gases emanating from the bleeding characteristic of this process.
  • Abdominal hernia: this is an opening in the abdominal walls that allows the tissue of an organ to protrude outward, which generates pain. Unlike the previous causes, this is a mostly active pain that manifests itself when the patient performs any activity that requires considerable effort in the abdominal area.
  • Stomach infection: a stomach infection can generate wounds in the walls of the stomach that manifest with an intense and unbearable pain throughout the abdominal area.
  • Indigestion: poorly digested food in the intestinal tract generates a large amount of gases that are highly likely to cause cramps in the abdominal area that generate a lot of pain.

What is electrotherapy and how can it help relieve menstrual pain?

Electrotherapy is a technique that consists of applying electricity to a person's body in order to generate a reaction in the body. It is a method that has been implemented for several decades, and today has hundreds of studies that confirm its effectiveness in relieving pain and strengthening muscles. Although there are more than 5 modalities, the most popular for everyday use are the following.

TENS

Transcutaneous nerve stimulation is nothing more than a form of electrotherapy that administers low-intensity, high-frequency currents to the body, acting directly on the nerves. In the case of menstrual pain, it acts on the enteric nervous system which is responsible for all intestinal processes, for it is there where the pain receptors of the entire abdominal region, including the belly, are located.

What TENS therapy does is that it alters the production of pain neurotransmitters, such as serotonin, so that this is reduced, while "numbing" the pain receptors of these substances, but requiring a greater amount of these to send a signal of intense pain to the brain. Both effects have the perfect synergy to alleviate your "suffering".

EMS

The second popular form of electrotherapy is electro muscle stimulation. This, unlike the previous one, uses higher intensity and lower frequency currents, which go directly to the abdominal muscles to generate a contraction similar to the one you generate naturally when you train your core in the gym.

This does not have any pain relief function, but focuses mainly on strengthening and toning the muscles, so it will not help you to relieve your belly aches, although it will help you to have a flat and toned abdomen.

Contraindications in the use of electrodes pads and electrotherapy

Contraindications for electrode placement

The placement of the electrodes is of utmost importance in electrotherapy, whether TENS or EMS, so here are some things to keep in mind before starting a session:

  • Symmetrical placement: the negative and positive poles of each electrode should be connected symmetrically. That is to say, if we use two pads, we should use one positive and one negative pole in each one, while if we use four, the equivalence should be two positive and two negative.
  • Do not cross the electrodes: you cannot use one electrode in the lower train and another in the upper train and more importantly, never cross the electrodes from the left side to the right side of the body and vice versa, since the current path can negatively affect the patient's health. For this reason it is always recommended to use the electrodes in a localized way.
  • Motor point: at least one of the electrodes, whether positive or negative, must be positioned over the motor point, which is the point where the greatest force is achieved in the muscle in question.
  • Control the intensity: the size of the muscle must be taken into account when choosing the intensity of the current, since the less volume and size the muscle has, the lower the tolerated intensity will be.
  • Be careful with the skin: EMS or TENS should not be used on recently depilated areas since the pores will be open and this could generate skin sensitivity. Do not use on irritated or reddened areas, open wounds or recent scars.

Contraindications for the use of electrostimulation

Being a therapy that applies currents to the body, it cannot be used for all conditions, therefore its use should be avoided in cases where the user suffers from the following conditions:

  • Epilepsy.
  • Cardiac pacemakers.
  • Circulation disorders and problems.
  • Abdominal or inguinal hernias.
  • Neurological disturbances.
  • Tendency to bleed.
  • Skin irritation, burns or wounds.
  • Diseases that affect muscle metabolism, such as diabetes.
  • Metabolic syndrome (diabetes, hypertension and obesity).
  • High uric acid levels.
  • Metabolic disorders and metabolic pathologies.
  • Inflammatory pathologies.
