How to use a TENS units & EMS machines for endometriosis? Placement of electrode pads

The functioning and internal structure of the female reproductive system obeys very delicate processes to maintain its balance and optimal functioning, so that an imbalance of any kind can cause a variety of diseases, which result in symptoms that can greatly impair the quality of life of patients.

Among the main diseases affecting the female reproductive system, we can especially highlight endometriosis, a disorder characterized by the pain it causes. Below, we will teach you everything you need to know about the causes and symptoms of endometriosis, and how to use TENS and EMS electrotherapy devices to relieve its symptoms.

How to use TENS machines to relieve endometriosis pain?

Since endometriosis is a condition that can be generated mostly by hormonal imbalances, the intensity of pain can vary from one area to another. Below, we will show you how to use TENS devices to treat endometriosis pain.

Where to place the electrodes?

Since the main pain in endometriosis occurs in the pelvic area, the electrodes should be positioned in the most relevant areas to stimulate the nerve endings that innervate the pelvic floor.

For this purpose, the optimal locations for TENS electrodes are as follows:

  • Lower lumbar area, just above the sacrum, interacting with the sensory roots of the sacral nerves
  • Perineum, between the vagina and anus, to directly stimulate the perineal nerve.

Which current to use?

Applying electrical impulses to the sacral and perineal nerves is an excellent way to treat pain caused by endometriosis, provided that the right frequency is applied to stimulate endorphin production.

For this particular case, shocks of 8 Hz to 250 microseconds can be applied, as well as shocks of 85 Hz to 75 microseconds. Both frequencies offer similar benefits at the nervous and muscular level for pelvic floor sensitivity, providing the patient with a sense of relief.

Best TENS units for treating uterine inflammation

While there is little study regarding the effectiveness of TENS therapy for the treatment of endometriosis, a large percentage of women have benefited from its effects, making it an option to consider. However, the lack of studies in itself is a reason why it is necessary to select the right device for the treatment, in order to apply an optimal therapy that does not generate pain in the patient. For this purpose, the best TENS units are:

Are EMS machines effective in strengthening muscles and preventing endometriosis pain?

Unfortunately, studies using EMS devices in patients with endometriosis or prone to endometriosis have been scarce, so there is no evidence that can confirm or disprove the usefulness of muscle electrostimulation for the treatment or prevention of endometriosis.

In addition, the very nature of EMS therapy makes its effectiveness for the treatment of endometriosis pain unlikely, since it is a physical conditioning method that, although it is suitable for muscle massage, has a base frequency that is too high to be plausible.

What is endometriosis and what causes it?

Endometriosis is a disorder that affects the endometrial tissue, which lines the inside of the uterus, causing it to grow outside the uterus, affecting the fallopian tubes, ovaries and the tissue lining the pelvis. This condition causes the endometrial-like tissue to break down, thicken and bleed with each menstrual cycle, causing it to become trapped inside the body.

The main symptoms of endometriosis are especially pronounced during the menstrual period, and are listed below:

  • Moderate to severe pain
  • Fertility problems
  • Excessive bleeding during menstrual periods
  • Diarrhea, bloating or nausea

Although the main cause of endometriosis is not clearly defined, it is possible to attribute to some explanations, such as:

  • Retrograde menstruation: a condition in which menstrual blood, containing endometrial cells, flows back into the body through the fallopian tubes instead of out, causing these cells to attach to the pelvic organs, where they grow and bleed each menstrual period
  • Implantation of surgical scars: there is a possibility that endometrial cells may attach to the pelvic organs after surgeries such as hysterectomy or cesarean section.
  • Immune system disorders: immune problems may result in the body's inability to detect and destroy endometrial tissue outside the uterus, allowing it to grow and affect the pelvic organs.
  • Peritoneal cell transformation: certain hormonal or immune factors can convert the peritoneal cells that line the inside of the abdomen into endometrial-like tissue.
  • Embryonic cell transformation: hormonal dysfunctions affecting estrogen production can cause cells in early stages of development to become endometrial-like cells. It is a process that can occur in the early stages of puberty.

Differences between TENS and EMS: Which is better for treating endometriosis?

Endometriosis is a condition that can cause considerable pain in the lower abdomen and pelvic area, making it necessary to apply therapy methods in order to treat the pain caused by this condition. This is where TENS and EMS electrotherapy methods come into play, both of which are very effective in relieving ailments caused by different types of disorders.

However, it is necessary to make the distinction between TENS and EMS electrotherapy technique, as well as their use and effect on the body. TENS therapy is a treatment method that involves the use of electric shocks that reduce the sensation of pain in patients suffering from various disorders.

The most distinctive characteristics of this technique are the following:

  • The intensity of its electrical currents ranges from 1 to 250 Hz, a relatively low frequency.
  • Its effect is applied on the micro nerve endings in the lower abdominal area and the nociceptors of the sciatic nerve that innervate the pelvis.
  • The electrical currents produced by TENS units prevent pain signals from traveling from the nerve receptors to the brain, causing a reduction in the sensation of pain.
  • It is a technique I have seen in many branches of physical therapy

On the other hand, Electro Muscular Stimulation, or EMS, is a training and fitness technique designed to improve the condition of muscle tissue. The following characteristics stand out in this type of therapy.

  • The base frequency of its electrical impulses is much higher, being fixed at a minimum of 70 Hz, and can reach up to 150 Hz.
  • It interacts on the muscle tissue, causing an increase in the creation of muscle fibers that cause its growth.
  • It is focused on training and physical conditioning
  • It can generate an aggressive response of the nervous tissue when applied to injuries and painful disorders.

With this information, it is concluded that to treat the pain caused in the pelvic area by endometriosis, it is necessary to apply the Transcutaneous Electrical Nerve Stimulation treatment, in order to numb the nerve endings of the sciatic nerve, which cause the sensation of pain in the pelvic area, causing it to reduce and generating a sense of relief in the patient.

It is necessary to highlight the fact that the effectiveness of the treatment varies from one patient to another, since although many women have treated the pain caused by endometriosis with TENS electrotherapy, there are reports of cases in which it offers practically no benefit.

On the other hand, muscular electrostimulation therapy does not provide any benefit to patients suffering from endometriosis, since it is mainly a hormonal disease, so the stimulation discharges on the pelvic floor muscles do not offer relief to the problem

Contraindications to the use of electrodes 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 on 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.
