Buying guide: What should I take into account to buy the best electro stimulator with 2 channels?

Dual-channel electrostimulators provide a wide variety of benefits thanks to their ability to cover a larger surface area of the skin, extending the area of effectiveness of the therapy. However, each ailment is different and its characteristics vary in relation to factors such as its origin, so it is necessary to take into account certain criteria to select the one that best suits your needs.

Types of uses

• Type of use: the uses that can be given to electrotherapy are very varied, and can range from pain relief and muscle relaxation to physical conditioning and post-surgical rehabilitation. These uses are factors to consider when selecting an electro stimulator.
• User experience: the variety of existing devices gives rise to machines with a large number of modalities, functions, intensity levels and modes of use, so it is necessary to take into account the user's experience using this type of device, to determine which brand and model offers adequate ease of use.
• Time of use: this is an important factor when determining the durability you need from your electrostimulator, since it may be necessary for prolonged periods of time, in cases such as the treatment of chronic ailments.

Technical characteristics

• Channels: this type of electro-stimulator has two transmission channels, to which the cables are connected, which in turn are connected to the electrodes.
• Pads/Electrodes: two-channel devices can accommodate a maximum of four cables, allowing up to eight pads to be attached.
• Modes/Programs: the number of programs available on the devices determines their range of effectiveness and the variety and types of ailments that can be treated by this means of this technique.
• Intensity levels: this is directly related to the programs, as each program can have several intensity levels. This is a factor to take into account when selecting an electrostimulator model, since a greater number of levels allows for a deeper reach of the electrical taxes.
• Type of screen: the most advanced electrostimulators have touch screens that allow greater ease of use and better visualization of programs and levels. It is a factor to take into account, but not a determining factor, since devices with analog screens offer very similar performance.
• Wireless: this is a factor that depends entirely on the buyer's needs according to the portability of the device.
• Heat therapy: although not all electro-stimulators have this feature, it is useful to take it into account due to its great effectiveness in the treatment of rheumatic ailments.
• Size: the size of the device plays a crucial role in determining its viability, although it is a subjective factor that depends entirely on the buyer's need. Larger electrostimulators are very useful for a wide variety of therapies, as opposed to their poor portability.
• Portable: depending on the routine and objectives of the buyer, it is necessary to take into account the portability of the device, as well as the space it occupies on the user's person, so that it does not interfere with daily tasks and allows quick access to electrostimulation.
• Types of electrodes pads: depends largely on the brand and model of the device. The most expensive ones use their own electrodes and can only be replaced in specialized stores. While other lower quality electro stimulators are compatible with universal pads.
• Type of battery: two-channel electro-stimulators can come with rechargeable or AA batteries. This feature influences the price of the devices, since although lithium batteries are more expensive, it allows saving on future expenses when acquiring new AA batteries.
• Reprogrammed timer: this is a very useful feature, although not indispensable for the operation of the stimulator. It allows a more precise management of the duration of each session.
• Combo: the highest quality devices have both Transcutaneous Electrical Nerve Stimulation and Muscle Electrostimulation functions. Devices with both features usually have a higher price.
• Interferential: this is an uncommon feature in most electrostimulators. Although it is very useful, the devices that have it usually have a higher price.
• Warranty: in general, the minimum legal warranty period in Europe is two years.
• Price: this factor mainly depends on the economic capacity of the buyer, although it is not a determining factor as long as the device meets the requirements.

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

In order to correctly apply any type of electrostimulation therapy, it is necessary to keep in mind that both TENS and EMS are oriented to different purposes, so a clear distinction must be made between the uses of each of these electrotherapy modalities.

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.
