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

In 2009, 50% of the world's population suffered from headaches constantly. By 2017, this number had risen to 75%, leaving a clear sign that more and more of us are affected by an ailment that, in itself, hides an uncertain number of causes.

In most cases, people turn to painkillers and other drugs to relieve pain, but TENS electrotherapy is a much more natural way to do it, without the risk of side effects. Below you will learn more about it and how it can help you neutralize your headaches and migraines.

How to use TENS machines for headache relief?

Using a TENS unit is quite simple, but we understand that it can be confusing at first. That is why we are going to show you below how to place the electrodes, and what intensity of current to use to relieve your headaches in just a few minutes.

Where to place the electrodes?

The placement of TENS electrodes on the skull follows the same principles as on other parts of the body. The first thing to do is to identify the point of pain and place the pads in an area where they "enclose" the pain so that the current flows through it.

Which current to use?

The voltage of the TENS currents is always the same, what we can modify is the frequency to be used, which can be between 1 Hz and 200 Hz. To treat headache we can use a frequency between 2 Hz and 4 Hz to stimulate the release of endorphins. While if we want to relieve more intense pain we can focus on the threshold of 80 Hz and 100 Hz.

More types of EMS electrostimulators and TENS machines you should know about

Are EMS machines effective for strengthening muscles and preventing headaches?

As we have discussed throughout the multiple articles on this website, EMS electrostimulation is designed to strengthen muscle mass and its use is not specific to pain relief. While EMS can strengthen certain parts of the neck and neck and thus avoid weaknesses that can trigger pain, for migraines and headaches are not the best option, for that we have the aforementioned TENS currents. They may be effective when the headache is about neck and cervical tensions

What are migraines and what are the causes?

Headache is any painful sensation anywhere in the skull. It is often called by various names around the world; such as migraine, a severe neurological disease that can cause disability or migraine, a form of intense headache that is accompanied by vomiting and dizziness, but the reality is that it is actually a symptom of these and other diseases, and often may not even have a pathological or malignant cause.

Among the most common causes, we can highlight the following:

  • Stress: raises cortisol levels, which is manifested in the body with acute headaches, especially in the temples.
  • Insomnia: not sleeping well has the same effect as the previous cause, raising cortisol levels and generating headache that may be accompanied by pain in the eye sockets.
  • Sinusitis: prolonged nasal congestion generates tension in the upper part of the skull, which manifests itself with intense pain in the region of the forehead and temples that appears on a regular basis.
  • Brain pathologies: any medical problem affecting the brain will manifest with pain in different areas of the head.
  • Excessive use of medications: some medications can alter your organism so much that they generate headache as a side effect that begins to show days or weeks after starting their consumption.

The reality is that a headache can hide a countless number of causes, so it is always important to consult a specialist when these appear too regularly. This way you will be able to rule out severe pathologies such as the following:

  • Migraine.
  • STROKE.
  • Cardiovascular accident.
  • Brain tumor.
  • Cerebral aneurysms.

What are the most common types of headaches?

Just as their causes can be varied, there is a wide range of ways to classify headaches. Below you will learn about the main ways in which this ailment presents itself in people who suffer from it.

  • Migraine headache: it is an intense pain in one of your temples, which is accompanied by other symptoms such as vomiting, altered vision and dizziness.
  • Tension pain: this is a dull, persistent pain felt in both temples and forehead, usually caused by stress, lack of sleep or anxiety. It may be accompanied by tenderness in the face and neck, or pain in the eye socket.
  • Cluster pain: is an intense and very repetitive pain that may occur several times a day. People describe it as a burning in the forehead and eye socket that may be accompanied by watery eyes, swollen eyelids and nasal congestion.
  • Exertional headache: a feeling of tension in the whole head or in the temples that is very common after extensive exertion such as running, jumping or lifting heavy weights.
  • Hypnic pain: a sharp pain in the temples that usually appears for no apparent reason, very common in people over 50 years old. It is known as "alarm clock pain" because it can start while you sleep and wake you up during the night, interrupting the sleep cycle.

There are 6 other types of headaches that are considered secondary because they manifest in a similar way to the previous ones, but are directly related to other conditions.

These are:

  • Pain due to excessive medication.
  • Menstrual pain.
  • Sinus pain.
  • Headache due to caffeine excess.
  • Headache due to traumatic brain injury.
  • Hangover headache.

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

Electrotherapy is an option that has gained popularity to treat various pains, including headaches, by offering quick relief without the use of drugs of any kind. Among them we have TENS and EMS, which are the best known at present.

TENS or transcutaneous electrical nerve stimulation, is a therapy that uses high and medium intensity currents, which when used on the skull, directly alter the way in which pain is generated and perceived in the brain. In this way, a sensation of relief is generated because the patient's resistance to pain is directly increased.

EMS or muscular electrostimulation is different, since it focuses on strengthening and toning the muscles, so although it can be used to relieve tension in the cervical area, it is not very effective for treating headaches due to the aforementioned causes.

So to relieve headache pain, without a doubt what you should buy is a TENS stimulation device, since it is designed exclusively for this purpose.

Contraindications in the use of the 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 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 affecting muscle metabolism, such as diabetes.
  • Metabolic syndrome (diabetes, hypertension and obesity).
  • High uric acid levels.
  • Metabolic disorders and metabolic pathologies.
  • Inflammatory pathologies.
