How to use a TENS units & EMS machines for neck pain relief? Placement of electrode pads

One of the most important sections of the back is undoubtedly the cervical spine, due to its proximity to the cerebellum, the brain, the large number of nerves that originate in it and a long etcetera of reasons. Its composition alone is a true anatomical marvel, but it is also one of the greatest torments of hundreds of millions of people in the world.

It is estimated that between 70% and 80% of humans will suffer at least once in their lives from neck pain, and those who don't will probably die before they feel it. Luckily, electrotherapy puts TENS and EMS therapies at your disposal, which can be a viable option to relieve and prevent any type of neck pain.

How to use a TENS machine to relieve neck pain?

Transcutaneous electrical nerve stimulation is undoubtedly one of the best ways to relieve neck and cervical pain. Thanks to it, you will not have to use drugs that can make you dependent on them, nor suffer perennial neck pain that ruin your lifestyle, since its currents do not alter the behavior of the nerves after their use, and offer a quick relief that is felt during the first seconds of starting a session.

Among the most important benefits for the neck we can highlight:

  • Avoid the use of drugs: undoubtedly one of the best news is that with TENS you will not need to use drugs to relieve your pain, so you will not become a dependent person who every year spends thousands of dollars at the pharmacy buying painkillers that generate side effects in your body.
  • Increases the pain threshold: since the cervical nerves will need more pain receptors to send a noxious impulse signal to the brain. This is a quality that will be maintained even after the sessions, so that when the pain reappears during the recovery process, it is no longer felt with the same intensity as at the beginning.
  • Reduces the production of pain neurotransmitters: these chemicals needed to generate a nerve impulse in any of the cervical nerves will be greatly reduced. This will not only be during your TENS session but also after it, which will allow you to have an even greater tolerance to pain.
  • It relaxes the cervical muscles: since it interferes with the reciprocal innervation that causes a muscle to tense when feeling pain, which increases the intensity of the pain. With the relief provided by TENS electrotherapy, these involuntary contractions are avoided and a total relaxation of the muscles that support the neck is achieved.

However, you should know that TENS electrotherapy will not cure the cause of your neck pain, it will simply relieve the pain in the area, but you should continue to perform the treatment indicated by your family doctor to recover from injuries such as:

  • Cervicalgia.
  • Nerve impingement.
  • Neck sprain.
  • Whiplash.
  • Torticollis.

How to use an EMS muscle electro stimulator for neck pain?

EMS electrotherapy is not recommended to relieve cervical pain, but this does not mean that you cannot take advantage of it, since the contractions obtained with it are of great help to prevent various neck and cervical back injuries.

In addition, it is an excellent way to maintain the firmness of trapezius, sternocleidomastoid and other surrounding muscles for people who do not have time to attend a gym.

Among its most valuable benefits we can highlight:

  • Prevents loss of elasticity: over the years the muscles lose elasticity, which causes them to become stiff, which increases the risk of injuries such as torticollis or contractures in trapezius. But this can be avoided with the use of EMS on a regular basis, as you will maintain the activity of the muscle fibers without having to invest long hours in the gym.
  • Improves neck stability: by strengthening the muscles involved in this function such as the trapezius and sternocleidomastoid mainly, but also others around them.
  • Prevents cervical injuries: problems such as torticollis, cervicalgia or nerve impingement that are products of excessive stress to which the joint is subjected will no longer appear as often, since you will have stronger muscles on which wear will have less impact.
  • Improves circulation: since during EMS sessions vasodilation is achieved in the cervical area that will speed up blood flow in the area. This will significantly improve the health of the neck muscles so that they are much more resistant to injury.
  • Reduces muscle stress: by using less intense currents, a gentle contraction of the cervical muscles is achieved that simulates a massage, so that these muscles relax and the accumulated stress in them is reduced.

Electrodes for neck

Electrodes for neck
  • To relieve cervical pain: Cervical pain can be located basically in any area of the neck, but is especially focused on the vertebrae, so it is likely that the pain follows the line of the cervical spine.
  • To relieve torticollis: Torticollis is usually generated by contraction of one of the two sternocleidomastoids or in one of the scalenes. Whatever the case, you should lie on your side, leaving the shortened section of the neck clear to place the electrodes.
  • To relieve whiplash: Whiplash usually affects both sides of the neck, so what you should do in this case is to lie on your stomach and position the electrodes.

More types of EMS electrostimulators and TENS machines you should know

Most common types of neck injuries

Strangely, the neck is the least protected part of the back despite being undoubtedly the most important. It has the fewest muscles even though it must support the weight of the entire head, it has some of the most fragile bones, and on top of that it is always exposed.

This makes it easy to suffer from injuries such as the following:

  • Whiplash: Whiplash occurs when the neck muscles are forced to move suddenly forward or backward, such as from sudden braking to avoid a car accident, being hit from behind in a car, or from a violent tackle while playing a contact sport. According to Harvard Health Publishing, more than one million Americans suffer this injury each year, and half of them are left with some type of recurring pain afterward.
  • Neck sprain: a very dangerous injury that occurs when the ligaments of the neck are forced to overextend, to the point of generating partial or total tears in them. A specialist should be consulted to rule out damage to the cervical vertebrae.
  • Neck fracture: it is generated when one of the bones of the neck fractures due to a sudden impact. It is one of the most dangerous injuries because if it affects one of the 8 cervical nerves or its vertebrae, it may cause paralysis of a part of the body and the patient may even be paralyzed.
  • Nerve impingement: occurs when one of the 8 cervical nerves is involuntarily shortened or compressed, which generates a sharp and persistent pain that can even limit the mobility of the neck.
  • Torticollis: consists of the temporary contraction of one of the neck muscles, which causes the head to tilt to one side and severe pain when trying to move this joint.

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

One of the best options to relieve neck pain caused by the aforementioned injuries is transcutaneous electrical nerve stimulation or TENS, which uses currents ranging from medium to low intensities to alter the pain transmission process that begins with the segregation of neurotransmitters and their reception by the C1, C2, C3, C4, C5, C6, C7 and C8 nerves that are distributed throughout the cervical area.

Then there is the electrical muscle stimulation or EMS, which uses medium and high intensity currents to achieve the contraction of the sternocleidomastoid muscles, the splenius of the head or the levator scapulae, among others that make up the cervical area. The aim is to strengthen these tissues in the same way as when training them in the gym.

For pain relief in the cervical area, the best choice is TENS unit, since it offers a method free of drugs and analgesic drugs to relieve pain by altering the nerve functions that generate it in the brain. On the other hand, EMS is contraindicated for the treatment of neck pain since the contraction it generates in the neck muscles can be harmful.

However, EMS electrostimulation can be a valid option to train the cervical area and strengthen it, in order to avoid all types of future injuries. For this reason, specialists recommend its use on a regular basis to achieve this particular objective.

Contraindications in 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.
