Types of TENS machines and muscle electrostimulators you should know about

Buying guide: What should I take into account to buy the best mini electro stimulator?

A mini electro stimulator is a very viable option for immediate relief of unforeseen ailments thanks to its portability and the fact that its size does not minimize its effects. However, each model of mini electro stimulator has its own set of characteristics and technical specifications, which you should take into account in order to acquire the best electro stimulator for your needs.

Types of uses

  • Type of use: you must be clear about the type of application you want to give the mini electrostimulator, since this therapy can be applied both for muscle recovery and for pain relief with TENS treatment programs.
  • User experience: some of these devices have a wide variety of functions, so it is necessary to take into account your own experience with their use, in order to acquire the model with an adequate level of ease of use.
  • Time of use: the quality of the product has a direct impact on its life span, so if you suffer from chronic ailments that require prolonged use of the mini electrostimulator, it is necessary to acquire higher quality equipment.

Technical characteristics

  • Channels: the number of channels available in a device increases its range of effectiveness, since it allows the use of a greater number of electrodes. For this reason, devices with two or more channels are recommended.
  • Pads/Electrodes: the number of electrodes usable on a mini electrostimulator corresponds to the number of channels available on the device. Two-channel devices allow the use of up to eight electrodes.
  • Modes/Programs: the number of modes the device has is crucial in determining its range of effectiveness, since it can treat a greater number of ailments and exert different effects on the muscles. The usual number of programs is between 5 and 20.
  • Intensity levels: the number of intensity levels varies from one model to another and the number of levels per program that the electro stimulator has will be decisive in measuring its efficiency, as well as the diversity of ailments that it can treat.
  • Type of screen: the most advanced mini electro-stimulators have LCD touch screens which greatly facilitate their use and programming, although their effect is similar to those with analog screens. This is an issue that mainly impacts the price, but not the performance of the device.
  • Wireless: most mini electro stimulators are wireless, thanks to their rechargeable battery, which gives them great portability.
  • Heat therapy: heat therapy is a very useful feature present in the most advanced mini electrostimulators. It is ideal for the treatment of rheumatic ailments such as arthritis and osteoarthritis.
  • Size: this is the factor that defines the portability of mini electrostimulators. In most cases it does not hinder its effectiveness, but smaller devices tend to have fewer features.
  • Portable: portability is the central point of mini electrostimulators. In this point, it is a matter of finding the right one for your needs, which has the right balance between size and functionality.
  • Types of electrodes pads: this point depends entirely on the brand and model, the most expensive brands usually have their own electrodes, which must be purchased in specialized stores, while others of lower quality have access to universal pads.
  • Battery type: most of these electrodes have a lithium battery, although it is possible to find some that work with AA batteries. This particular feature impacts both the price of the device and future expenses.
  • Pre-programmed timer: this is a very useful feature that allows you to accurately measure the duration of each session. It is not present in all devices and is not indispensable, so it is at the buyer's discretion.
  • Combo: depending on the use you want to give the device, it is convenient to check if it has functions to apply TENS and EMS therapies. Not all mini electro stimulators have these features.
  • Interferential: this is a feature to take into account when deciding on a device, although it is not present in all, so it can increase the price. In addition, there are electrostimulators specially dedicated to interferential therapy.
  • Warranty: in general, the minimum legal warranty period is two years.
  • Price: although it is an important factor, it is completely subjective, since its viability depends on the purchasing power of the buyer and the number of functions of the device, as well as its quality and warranty.

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

Transcutaneous Electrical Nerve Stimulation (TENS) therapy and Electrical Muscle Stimulation (EMS) are electrotherapy techniques that differ greatly, so it is necessary to know the effects of each of them.

TENS Units

  • Treatment of acute ailments: 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 or 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 for maintaining physical activity when it is not possible to perform complete exercises or to recover muscle 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 Mini TENS and EMS machines

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: one electrode cannot be used on the lower train and another on 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, should 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.
