What is a muscle stimulator?

Also known as TENS machines or EMS units, muscle electro stimulators are electronic devices that send electrical impulses to the body in order to contract the muscles. This results in the release of endorphins and the reduction of pain after exercising so that the athlete can relax.

These impulses are sent from the device to several electrodes in the form of pads or adhesive patches that are placed on the skin and on the muscles that one wants to work on. These impulses imitate the action that comes from the central nervous system, which causes the desired muscular contraction.

Another benefit of these devices is that they improve blood circulation, are portable and can be used anywhere. They are even useful for physiotherapy.

Differences between TENS and EMS

Transcutaneous electrical nerve stimulators (TENS) are devices that, like EMS, send low voltage electrical impulses to stimulate certain natural actions of the body. The main difference is that TENS stimulates the nerves to prevent pain signals from reaching the brain. On the other hand, muscle electro stimulators are used to contract the muscles of the body, as explained above.

Both devices have totally different uses. If you are looking to improve your training, gain muscle and improve your performance, what you need is a muscle stimulator; but if your goal is, for example, to alleviate chronic back pain, the device you need is a TENS.

It is that the transcutaneous electrical nerve stimulators have as main objective the treatment of chronic and acute pain such as arthritis, carpal tunnel syndrome, foot pain, sclerosis, among others.

Uses of the muscle stimulator

EMS is used for various purposes such as strengthening muscles, preventing muscle atrophy due to disuse, improving blood circulation, relaxing the athlete, helping to tone muscles and giving them a more aesthetic and attractive appearance, and others such as the following:


They allow to improve the circulation and to remove lactic acid that causes fatigue.


The training is your main objective. Improves performance, strength endurance and allows you to gain muscle mass by increasing the size and density of muscles as if you lift weights. Include this device in your exercise routine and you will see great results.


Patients who have suffered muscle or skeletal injuries also use EMS. It allows them to strengthen and gain muscles safely and effectively.


They are excellent for efficient warm-ups before starting training.

Improve blood circulation

This machine can help patients recover quickly. This is achieved by improving circulation and removing lactic acid to heal more quickly.

Prevent atrophy

In other words, it prevents the muscles from weakening after an injury or while recovering from neurological injuries.

Things to look for when choosing muscle stimulator

You must take into account certain criteria before buying a muscle stimulator, among them, we find among others: intensity levels, programs, number of channels, battery or rechargeable, wireless technology or not, compliance with standards in force. So take what suits you and seems to you the most judicious.

Intensity levels

All electrostimulation devices offer several intensity levels. The more there is, the better because it allows you to truly adjust the device to your body. It is up to you to choose the intensity according to your feelings. The more possibilities, the more you will have an intensity that suits you.


The number of programs is obviously important as well as the categories to which they belong (health/sport/well-being, etc.) The more varied the programs and categories, the more versatile the electrostimulation devices. Preferably choose a device with several programs in the category you want to use.

Available Channels

The number of channels determines the number of muscle areas that can be stimulated at the same time. Therefore, the more channels, the more zones you can stimulate simultaneously! For those who wish to stimulate only one muscle area at a time, no need to choose a device with several channels (sometimes more complicated to connect if they are wired).


Some electrodes are disposable which must be replaced from time to time. Other electrodes are made of carbon with anti-wear contact and cannot be replaced. Some work with the addition of a gel or cream while others do not. ;It is up to you to see what you prefer, but count all this consumable in the costs and expenses related to the muscle stimulator.

Wireless models

We recommend buying a device that benefits from wireless technology to have greater freedom of movement. The muscle stimulator (TENS Machine) is easier to use and put into operation since there is no need to connect the wires. More practical and therefore easier to use, we prefer. However, some wired stimulators are fairly easy to use and may still interest you (a little cheaper in general than wireless).

Types of the used batteries

It is important, for economic and ecological reasons, to take into account the means of operation: battery or rechargeable battery. We recommend buying a device using a rechargeable battery, which is easier to use: the indicator light alerts you that you need to recharge, and you don’t have to buy batteries (in addition to the device)! Batteries are not always supplied with the stimulator!
