How to use a TENS units & EMS machines for face pain and toothache? Placement of electrode pads (UK)

The face is one of the areas most populated with muscle and also one of the most prone to suffer pain of different types due to a wide variety of causes, which can be muscular or neurological, since it also has many nerve endings.

For this reason, suffering from pain in various areas of the face is a more common problem than you might think, and for this type of situation, TENS and EMS units therapies are of great help. Therefore, in the following paragraphs we will teach you everything you need to know about the use of electrostimulation to deal with aches and pains in the face.

How to use a TENS machine to relieve facial pain?

TENS therapy units are specifically designed to provoke in the patient the sensation of relief for people who have suffered injuries or nerve disorders in the face.

Among its most outstanding benefits we can mention the following:

  • Numbs the pain receptors: the discharges applied by the device directly affect the pain receptors in the face located in the cranial nerve and the trigeminal nerve, in order to improve pain resistance during and after the session.
  • Provides an analgesic effect: by means of this therapy, the cell groups along the face, responsible for causing the sensation of pain are suppressed, thus producing a sensation of immediate relief in the user.
  • It avoids reciprocal innervation: in this way a relaxation of the motor root and the parasympathetic root of the intermediate cranial nerve is achieved, causing an analgesic effect along the facial structure.
  • Vasodilation: the electric shocks applied on the face generate heat, which causes the dilation of the blood vessels that extend along the facial structure, generating in turn a sensation of local analgesia, which causes and maintains a feeling of relief that lasts until minutes after the session.

It is necessary to highlight the fact that transcutaneous electrical nerve stimulation is not a method to cure the injuries or disorders that are causes of facial pain, but a method to deal with the pain itself.

However, it is the ideal solution to provide a sense of relief to the symptoms of various injuries, besides being very useful to treat the sequelae of disorders such as:

  • Painful tic
  • Migraine
  • Fibromyalgia
  • Sinusitis
  • Temporomandibular Joint Dysfunction Syndrome (TMJ)

  • For pain in the maxillary muscle: If the pain is centered in the lower part of the maxillary muscle, the first electrode should be positioned in the muscle belly of the same, while the second should be placed in the risorius muscle, so that the discharges move between electrodes and attenuate the sensation of pain.
  • For trigeminal neuralgia: Trigeminal neuralgia can cause pain in various areas of the face, since its branches are located on both sides of the face, between the forehead and the jaw. To treat this disorder, you must position the first electrode over the trigeminal ganglion, located in the temporal region, while the position of the second electrode is variable, since it must be positioned in relation to the nerve branch responsible for the sensation of pain.
  • For nasal contusion: In the case of receiving a strong blow to the nose that generates pain, the TENS electrodes should be placed in such a way that they enclose the area of nasal pain to ensure lasting relief.
  • For the zygomatic muscle: The first of these is the zygomatic muscle, in which case the electrode is positioned in the middle area of the zygomatic muscle, located between the corner of the mouth and the maxillary joint.
  • For the corrugated and orbicularis muscle: The second muscle is the corrugated muscle, which spans the eyebrow line. In this case, the electrode will be positioned on the inner arch of the eyebrow. Then there is the orbicularis muscle, which encompasses the eyelids and are very superficial, as they are located just under the skin. For this muscle, the electrode will be placed on the lower part of the orbicularis, just below the eye, aligned with each side of the ocular iris.
  • For the maxillae: Finally, there are the maxillary muscles, which make up a large part of the facial structure, and for which the optimal electrode position is in the muscle belly on each side, to maximize jaw relaxation.

Most common causes of face pain

The face is made up of a large number of muscles and nerves that can suffer injuries or diseases that can cause considerable pain. This pain varies depending on the type of injury and can be dull and throbbing, or intense discomfort centered in various areas of the facial structure.

The most common causes of facial pain are as follows:

  • Dental abscess: is the accumulation of pus caused by a bacterial infection that can occur in various areas of the tooth and for various causes. Among other symptoms, it can cause discomfort, tooth sensitivity, swelling over the tooth and swollen glands.
  • Headache: primary disorder of the nervous system that produces incapacitating pain such as migraine or migraine. Its main symptom is a generalized pain around the head and face, which can vary in intensity and frequency. In general, it is caused by physical or emotional stress, colds, dental problems and eye strain, among others.
  • Jaw fracture: a very common injury in boxers that occurs from receiving a strong blow to the mandible, which is the bone that supports the lower teeth and shapes the jaw. It will manifest with excessive swelling also due to the large number of blood vessels in the area, and acute pain.
  • Septal deviation: another very common injury in boxers that occurs when the nasal septum receives a strong blow that causes it to move out of position, which also usually causes damage to the nasal turbinates.
  • Facial trauma: can affect the jaw, cheeks, nose, eye socket or forehead, and is caused by a blunt impact on the face. Its most common causes are fights and traffic accidents.

Differences between TENS and EMS: Which to use for facial pain?

The use of transcutaneous electrical nerve stimulation therapy , or TENS, is intended for the treatment of pain in localized areas, making use of electrical currents which act directly on the facial nerve endings, relieving the sensation of pain throughout the session

EMS, or muscular electrostimulation, is a physiotherapeutic and training technique focused on muscle conditioning, being widely used in sports environments for training and recovery of athletes. It uses medium-high intensity electrical impulses, between 70 and 150 Hz, which cause muscle contractions in isolated groups that serve to increase their mass, elasticity and speed of recovery.

With this information, we can say that in cases where facial pain afflicts the patient, the ideal therapy is transcutaneous electrical nerve stimulation (TENS), since most ailments affect the facial nerve, and this modality of electrotherapy intercepts the transmitters that generate the sensation of pain in the face. In addition, the sensory innervation of the face is distributed along its entire length, thanks to the three divisions of the cranial nerve, so the effectiveness of this therapy is quite high.

Because most facial ailments affect the facial nerve, EMS is not a solution for facial pain, since its main quality is the stimulation of muscle contractions, which can be counterproductive for the treatment of pain in the different regions of the face. Although EMS therapy is very useful for aesthetic purposes, it is contraindicated for the treatment of facial ailments and injuries.

Contraindications in the use of electrodes and electrotherapy

</p> <h3>Contraindications for electrode placement</h3> <p>
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.
</p> <h3>Contraindications for the use of electrostimulation</h3> <p>
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.
