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

Although a large number of injuries locally affect a joint or nerve, there are disorders and conditions that can cause widespread pain in many areas of the body, greatly reducing the quality of life of those who suffer from these disorders. One of the most common of these conditions is fibromyalgia.

This disorder can greatly increase patients' sensitivity to pain, which can be generalized or localized, and for which it is necessary to find methods for the treatment of this particular symptom. This is where TENS and EMS electrotherapy comes in. In the following paragraphs, we will teach you the most salient characteristics and symptoms of fibromyalgia, and how to apply electrotherapies effectively to treat its symptoms.

How to use TENS machines to relieve chronic pain?

Since the main symptom that characterizes the condition of fibromyalgia is generalized pain, the effective application of TENS unit therapy can be very useful to prevent the condition from affecting the patient more than necessary.

Below, we will teach you what you need to know to apply TENS correctly:

Where to place the electrodes?

Unlike injuries or other disorders such as carpal tunnel syndrome, whose symptoms focus on a specific area of the body, the pain caused by fibromyalgia affects the entire musculoskeletal system, so the pain occurs simultaneously throughout the body, being more intense in some areas than in others.

The areas in which the pain is most intense differ from one patient to another, and the positioning of the electrodes should prioritize these areas, being applied first to the area of the body in which the patient expresses the most intense pain.

From there, the ideal procedure is to apply the therapy over the areas in order of decreasing intensity, until the pain sensation is sufficiently reduced.

Which current to use?

The fact that fibromyalgia is a neurological disorder that affects the body in a generalized way at the nervous level, in addition to variations in the intensity of the pain it presents in different cases, makes it a complex task to define the ideal intensity for TENS treatment.

With this said, the priority in these cases is to numb the nerve endings of the affected area and to promote the release of endorphins that allow the patient to get rid of the pain sensation. For both purposes, the ideal base intensity is 100 Hz, which can be increased according to the intensity of pain presented by the patient.

What is fibromyalgia and what are the causes?

It is a chronic neurological disorder characterized by a generalized pain sensation that affects the musculoskeletal structure, in addition to producing fatigue, sleep disorders, memory problems and mood changes. It is believed that fibromyalgia affects the central nervous system amplifying the perception of pain.

The main symptoms of this disease are the following:

  • Muscle and bone pain: Fibromyalgia causes widespread pain that is described as constant, mild and bothersome, lasting at least three months. The widespread pain affects both sides of the body, above and below the waist.
  • Fatigue: the pain associated with fibromyalgia constantly disrupts patients' sleep, with others reporting waking up tired despite getting plenty of sleep, as well as suffering from other sleep disorders.
  • Cognitive problems: Fibromyalgia causes difficulty in attention, concentration and focus, due to an effect called "fibrom fog".

What are the most common types of fibromyalgia?

The nature of fibromyalgia and its link to the motor apparatus, in conjunction with the multiple symptoms that accompany the disease, give it a variety of types that are classified according to different criteria.

The most commonly treated and common types of fibromyalgia are the following:

Idiopathic fibromyalgia (type I)

Idiopathic fibromyalgia is the type of fibromyalgia that produces in the patient a high sensitivity to pain. It is one of the most common types and unlike other types, the complaints are not associated with psychopathological processes.

Patients diagnosed with this type of fibromyalgia demonstrate a stable mood and usually a control over reactions to pain, although they also present severe cases of hyperalgesia (high sensitivity to pain).

Chronic disease fibromyalgia (type II)

Fibromyalgia type II is closely associated with chronic diseases of any type from degenerative to neoplastic, but most cases are diagnosed in patients suffering from chronic rheumatologic diseases.

One of the most common disorders leading to type II fibromyalgia is rheumatoid arthritis, in addition to many other systemic diseases and locoregional processes. The latter have a high probability of developing fibromyalgia.

Psychopathological fibromyalgia (type III)

This type of fibromyalgia is highly related to psychological disorders that make the involvement of a psychiatrist in the treatment of the disease indispensable. Type III fibromyalgia develops more easily in patients with severe psychopathological disturbances.

It is very common in patients with psychopathological pictures of anxiety, depression and dissociation, which derive in a hypersensitivity to pain and very low values of self-control over it.

Simulated fibromyalgia (type IV)

Consists of a group of patients who simulate fibromyalgia, taking advantage of the fact that the characteristics of the condition are well known and the lack of tests to diagnose it accurately.

It is usually done by individuals seeking to obtain a permanent leave from work, and once obtained, patients stop going to doctors' offices. There are certain objective tests to identify such patients, although they are not 100% accurate.

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

One of the most effective methods for the treatment of fibromyalgia is electrotherapy, thanks to its effects that favor direct pain relief. However, it is necessary to take into consideration the distinctions between Transcutaneous Electrical Nerve Stimulation (TENS) and Electrical Muscle Stimulation (EMS).

TENS is used as a physiotherapeutic technique that uses low-intensity electrical impulses to treat ailments caused by various injuries and disorders, including fibromyalgia. The main characteristics of this treatment are the following:

  • Its electrical impulses range from 1 to 250 Hz.
  • It interacts directly with the sensory branches of the areas most affected by fibromyalgia to reduce the sensation of pain.
  • It is one of the most widely used methods for the treatment of symptoms caused by disorders such as fibromyalgia and similar.
  • It is not a method to eliminate the disorder, only to make the treatment more bearable.

For its part, EMS is used as a method of physical training for athletes and as a method of physical rehabilitation therapy for the recovery of muscle mass after time of inactivity. It is identified by the following characteristics:

  • It applies high base intensity electrical impulses, at a minimum of 70 Hz and a maximum of 150 Hz.
  • It directly influences the muscle tissue by means of contractions that stimulate the regeneration of muscle fibers.
  • It is widely used to increase muscle strength, endurance and elasticity.
  • It does not interact directly with nervous tissue.

With this information, it is clear that TENS therapy is the ideal choice for treating the symptoms of fibromyalgia, thanks to its abilities to numb the nociceptors of the sensory branches of the nerves in the areas most affected by pain.

Because fibromyalgia is characterized by widespread pain, it is necessary to focus on the parts of the body that are subject to the most pain, and gradually move on to those with a more tolerable level of pain.

On the other hand, EMS is completely contraindicated for the treatment of pain caused by fibromyalgia, because this ailment does not qualify as an injury that requires physical rehabilitation, but as a neurological disorder that affects the brain and nervous system, so in the best case, EMS muscle stimulation will have no effect, while in the worst case it could cause even more pain in the patient.

Are EMS machines effective in strengthening muscles and preventing fibromyalgia?

Although EMS machines provide essential physical conditioning to prevent injuries and some types of disorders, fibromyalgia cannot be prevented by the use of muscle stimulation impulses, simply because the origin of the ailment is not muscular, but neurological and, in some cases, even psychological.

Specifically in cases such as fibromyalgia type III, related to psychopathological conditions, the origin is found in the psychiatric disorder that the patient may appear to have, rendering ineffective any attempt to apply physical therapy for the treatment or prevention of the disease.

Contraindications to 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 on each one, while if we use four, the equivalence should be two positive and two negative.
  • Do not cross the electrodes: one electrode cannot be used 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 affecting muscle metabolism, such as diabetes.
  • Metabolic syndrome (diabetes, hypertension and obesity).
  • High uric acid levels.
  • Metabolic disorders and metabolic pathologies.
  • Inflammatory pathologies.
