Buying guide: What should I take into account to buy the best electro stimulator with 4 channels?

The variety of 4-channel electrostimulators that can be found on the market is very wide, so selecting the right device for your needs can become a more complicated task than expected. For these cases, it is necessary to take into account a variety of criteria to select the right electrostimulator, according to the application you plan to give to it

Types of uses

• Type of use: 4-channel electrostimulators have a wide variety of uses thanks to their intrinsic versatility, allowing a wide coverage for strength training, muscle massage and TENS treatment.
• User experience: this type of device requires some experience for the proper positioning of the electrodes on the areas to be treated, the correct configuration of the current output, the proper manipulation of the stimulation modes and levels.
• Time of use: the amount of time you plan to use the electro stimulator will be a determining factor when selecting the right device, since you must keep in mind the quality of the device.

Technical characteristics

• Channels: its 4 channels allow the insertion of 4 functional cables that facilitate the coupling of up to 8 electrodes, by means of which a great coverage is achieved in the area to be treated. It is especially useful for large areas such as the back
• Pads/Electrodes: number of electrodes that you can use at the same time, useful to cover larger body areas such as the back, buttocks or legs, in some electro stimulators you have the possibility of adding as many electrodes as required.
• Modes/Programs: one of the greatest advantages of this type of electrodes is that it has a large number of programs and modes of use dedicated to the treatment of ailments at different levels, as well as muscle conditioning. It is possible to find devices with up to 50 modes of use.
• Intensity levels: these are related to each of the modes of use individually, which means that each program has a variety of levels. The number of levels each mode has will determine the depth to which the electrical impulses can work.
• Type of screen: The type of screen an electrostimulator has determines how easy it is to use. Although touch screens offer greater accessibility to the device's functions, they can be complicated for some people. Purchasing a touch screen device will depend on the user's experience, since this feature does not influence the performance of the machine.
• Wireless: this is a point of great importance, to which you should pay attention in case you are looking for a portable device. The most modern wireless devices work with lithium batteries and electrodes that operate via wifi network, linked to a mobile application. Again, the deciding factor will be the user experience
• Heat therapy: this feature is very useful, and a function you should look for if your goal is to treat ailments caused by injuries or rheumatic diseases such as arthritis, osteoarthritis or gout.
• Size: this will determine the portability of the device, and whether it will be possible to carry it on your person. The size is also usually related to the number of channels and functions available on the electrostimulator.
• Portable: the portability of an electrostimulation device will determine the ease of spontaneous use of the device, as well as the ease with which the user will be able to carry it. This characteristic is entirely at the discretion of the purchaser.
• Electrode pads types: higher quality devices have their own electrodes, which can only be replaced by special order. Other devices have accessibility for the use of universal electrodes. In addition, it is necessary to be aware of the compatibility of the device with electrodes of various shapes.
• Battery type: this feature usually has a great influence on the overall cost of the device. Stimulators with a lithium battery tend to be much more expensive, but their rechargeable battery gives them a much longer service life. While devices that work with cylindrical or 9V batteries are cheaper but in the long run the expense of replacing the batteries is usually higher.
• Pre-programmed timer: although it is not an indispensable function, it is very useful both for physiotherapists and for people who perform their own therapies. This feature makes it much easier to keep track of the duration of each session.
• Combo: although not all electrostimulators include the TENS and EMS therapy functions simultaneously, it is one of the most versatile features that can be found, so acquiring an electrostimulator of this type is an excellent option.
• Interferential: this function is ideal for the treatment of ailments at the muscular level whose focus is in the deep tissue layer. It is not a function that is commonly included in conjunction with TENS and EMS devices, but it is very easy to find electrostimulators dedicated to interferential therapy.
• Warranty: Warranty periods differ between regions, suppliers and stores. In regions such as Europe, the legal minimum warranty period is two years
• Price: this is a very important factor, but should not ultimately determine the decision to purchase an electrostimulator. Better quality devices are usually more expensive, so it is necessary to find the right balance between price, quality and warranty.

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

Although electrostimulation therapies share the principle of the use of electrical impulses, their application and functions are completely different, so it is necessary to highlight the purpose of both TENS and EMS therapy, in order to apply them correctly and get an idea of the results that will be obtained after each session.

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 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 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.
