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

As a result of the large number of electrostimulators that exist and their different types, it is necessary to take into account certain factors in order to determine which type and model of device best meets our needs. Below, we will show you some points to take into account when selecting the most suitable electrostimulator.

Types of uses

• Type of use: Electro stimulators can serve a variety of functions in the field of physiotherapy, and this is something to consider when selecting the one that best suits your needs. You should be clear about whether you want to relieve pain in a particular area, reduce tension in certain muscles and tone certain muscle groups without damaging the joints.
• User experience: this factor will determine whether you opt for models with more complex functionalities, or if you prefer to purchase an electrostimulator with simple, to-the-point functions, which are easier to use.
• Time of use: this is a point to take into account if you plan to apply EMS training in the long or short term, or if you suffer from a chronic ailment that requires long-term TENS treatment. This directly influences the quality of the electrostimulator you should select.

Technical characteristics

• Channels: the best quality rechargeable electro stimulators have two channels for the insertion of two or more leads.
• Pads/Electrodes: most devices have four connectors that allow them to accommodate up to eight electrodes.
• Modes/Programs: Wireless electrotherapy devices have a variable number of programs, ranging from five to 20 programs. These programs, in most cases, must be activated and set manually within the electro stimulator.
• Intensity levels: the best electro-stimulators can have up to 20 intensity levels within each program.
• Type of screen: among the various types of rechargeable electro-stimulators we can find those with an analog screen, which usually have a size of 4.5 cm x 3.5 cm, with slight variations between the different models. And those with a touch screen, whose standardized size is 15 cm x 10 cm, with slight variations from one model to another.
• Wireless: they only require physical connection to the current to charge the battery.
• Heat therapy: the best quality electrostimulators contain the heat therapy function among their massage modalities.
• Size: there are different models of rechargeable electrostimulators that adapt to the needs of each user.
• Portable: this type of electrostimulators are portable, and their only requirement is to keep the power cable at hand.
• Types of electrodes: the most recognized brands of electro stimulators customize their electrodes so that they are only functional with the pads included with the device. However, it is possible to find electro stimulators with compatibility for universal electrodes at a lower price, although their quality is usually lower.
• Battery type: most rechargeable electro stimulators choose to work with lithium batteries, eliminating the need to use AA batteries and eliminating the risk of interrupting sessions.
• Pre-programmed timer: certain devices have a timer function, which will be very useful in maintaining the accuracy of the duration of electrotherapy sessions.
• Combo: most rechargeable electrostimulators apply only one type of frequency, either TENS or EMS, although the higher quality ones have the ability to apply both types of therapy. The latter are usually quite expensive.
• Interferential: the most advanced and expensive models may include interferential therapy among their modalities of use, although there are devices dedicated to this type of therapy.
• Warranty: the minimum warranty by law for devices of this type is two years in Europe, this figure may vary around the world, depending on the consumer protection laws of each region.
• Price: Price can be a major factor in deciding on a device, and these come in a wide range.

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

Both electrostimulation modalities offer advantages to their users within their field of effectiveness, however, it is necessary to highlight that both TENS and EMS exert different effects on the body, so it is necessary to distinguish between the advantages that each frequency offers.

TENS units

• Relief 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 (muscles, ligaments and tendons), 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.
