Differences between TENS and EMS: Which one is better for me?

Electro Muscle Stimulation (EMS) and Transcutaneous Electrical Nerve Stimulation (TENS) therapies are among the most effective physical therapy modalities thanks to the effect they exert on sensory and motor nerve fibers, in addition to muscle and fibrous tissue.

However, it is necessary to take into consideration the difference between both types of therapies in order to provide a correct application of the different types of therapies.

TENS units

  • Treatment of acute pain: it is an excellent method for treating recent pain, since its electrical impulses quickly inhibit the sensation of pain in the affected area.
  • Treatment of chronic pain: prolonged treatment with TENS electrostimulation presents a gradual decrease in chronic pain.
  • Muscle relaxation: its electrical discharges promote the relaxation of fibrous tissue, decreasing muscle tension and reducing the sensation of pain.
  • Pain caused by hormonal imbalances: TEN therapy is very useful in relieving the sensation of pain caused by hormonal conditions such as endometriosis or dysmenorrhea.
  • Pain caused by rheumatic diseases: it is an option to consider for the treatment of ailments such as those caused by rheumatoid arthritis, sciatica and gout.

EMS electrostimulators

  • Muscle toning: the electrical impulses generate contractions that improve the elasticity and resistance of the muscle fibers worked.
  • Maintaining and resuming physical activity: it is an excellent option to maintain physical activity when it is not possible to perform complete exercises, or to recover muscular condition after a prolonged period of sedentary lifestyle.
  • Rehabilitation of the musculature after injuries: it is widely used in the field of physiotherapy to recondition a muscle or muscle group that has gone through its recovery period, after a surgical process or an injury.
  • Increased recovery of muscle tissue: the activation of muscle groups caused by the high intensity electrical impulses of EMS promotes the recovery of muscle fibers.

Contraindications in the use of TENS and EMS machines

</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: 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.
