Types of TENS machines and muscle electrostimulators that you should know about

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

Electrostimulators have a large amount of functionality that makes them versatile, since they can be oriented to a specific purpose, or be multipurpose. For this reason, it is necessary to take into consideration certain points when acquiring the appropriate device.

Types of uses

  • Type of use: there are electrostimulators that offer different types of electrotherapy, so you should determine whether you plan to use it for treatment of ailments, rehabilitation, muscle training, or another purpose.
  • User experience: the number of functions and methods of use varies from one electro stimulator to another, making the difficulty of programming them also variable. You should be aware of your own experience with this type of device in order to select one with appropriate ease of use.
  • Time of use: the quality of the electro-stimulators determines in many cases their useful life, so it is necessary to have an idea of how long you will need it for, in order to acquire a device with a useful life adequate for the buyer's purposes.

Technical characteristics

  • Channels: although portable electrostimulators tend to be compact in size, the best quality ones can have a maximum of two channels, allowing the insertion of four lead wires.
  • Pads/Electrodes: the number of adaptable electrodes depends on the number of channels available, with a maximum of eight electrodes in two-channel stimulators.
  • Modes/Programs: this is a determining factor in the amount of ailments or training that can be applied by each device. The most versatile devices can have between 15 and 20 programs, giving them a wide coverage for your treatments.
  • Intensity levels: these are independent of each level and vary depending on the brand and model of the devices. They directly impact the effectiveness of the treatments, since a high intensity level allows the impulses to reach deeper into the muscle and nerve tissue.
  • Type of screen: LCD touch screens offer greater ease of use, since they allow better visibility and smoother handling of the device's functions. This is a feature that mainly impacts on price, since analog screens are much cheaper and offer similar quality.
  • Wireless: by default, portable electrostimulators are wireless, although it depends on the type of power source. They may use lithium batteries, which require the use of a charger, or AA batteries, for which spares need to be on hand.
  • Heat therapy: this is a very useful modality for users who wish to treat rheumatic disorders such as osteoarthritis and gout. It is not present in all devices and impacts the price, so it is advisable to purchase devices with this function only if necessary.
  • Size: the point of a portable device is that it should be compact enough to fit at least in a backpack or purse. There are models of different sizes, so you should select it according to your circumstances and needs.
  • Portable: they should be small enough to be carried on your person, or at least in a backpack.
  • Types of electrodes pads: this is a factor that varies depending on the brand and model of the device. The more expensive ones have their own electrodes, while cheaper brands are compatible with universal electrodes.
  • Battery type: lithium batteries have a much longer life and are much more economically efficient than AA batteries, due to the substantial savings of not having to buy spare parts for the latter.
  • Pre-programmed timer: although not an indispensable feature, it is very useful for keeping track of each electrotherapy application. Purchasing a device with this feature is completely up to the buyer.
  • Combo: the most versatile devices have both Transcutaneous Electrical Nerve Stimulation and Muscle Electrostimulation functions, allowing a greater variety of situations to be addressed with a single device. While offering considerable benefits, the presence of both functions has a significant impact on the price of the machine.
  • Interferential: a very useful feature due to its ability to have a deep tissue effect and no side effects. It is not very common in most devices and those that do have it tend to be expensive.
  • Warranty: the minimum warranty by law for electrotherapy devices in Europe is two years.
  • Price: the importance of this factor is determined by the purchasing power of the buyer, although it should never be a decisive factor when acquiring a device that may have all the features you need.

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

Electro Muscular Stimulation (EMS) and Transcutaneous Electrical Nerve Stimulation (TENS) are the most used physiotherapy techniques for the treatment of ailments and muscular rehabilitation, and since both therapies are oriented to different purposes, it is necessary to take into consideration what each of them is for, in order to apply them correctly and obtain optimal results.

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 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 portable 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: 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.
