Five Best EMS Units of 2021

Five Best EMS Units of 2021

EMS or electric muscle stimulation is a technique used in electrotherapy that is designed to stimulate the muscles using electrical impulses to achieve a wide range of medical outputs. EMS is designed to deliver small, low voltage electrical impulses via accurately placed electrodes on the skin. These electrical impulses make the muscles contract and relax in tandem to thus reduce pain, alleviate discomfort, reduce inflammation and enhance their performance. Electric muscle stimulation is excellent not only for reducing pain but also enhancing the performance of the muscles and avoiding fatigue during excessive workouts.

How Does an EMS Unit Work?

EMS units are devices that use electric muscle stimulation to relieve muscle pain, nerve pain, and joint pain. An EMS unit contains an impulse generator which is wired to electrodes that are placed on the skin. The impulse generator sends micro impulses that are directly delivered to the muscles resulting in their contraction. The repeated and frequent contraction and relaxation helps the muscle gets stronger, relieve pain, and has other benefits as well, such as:

Relaxes the muscle Prevents any muscle atrophies Speeds up the healing of the muscle Minimizes any inflammation Stimulates muscle growth Improves blood circulation to the muscle Aerates the muscle

EMS Unit v/s TENS Unit

TENS units are also excellent conduits of electrotherapy but the major difference between a TENS unit and an EMS unit is the purpose they serve. TENS units are designed to relieve pain, inflammation and discomfort. EMS units on the other hand are not used for just these three things but are also designed to stimulate the muscle resulting in its growth, relaxation, and strengthening it. Muscle spasms, muscle atrophy, poor blood circulation to the muscle, are some of the common conditions that can be alleviated using an EMS unit.

How to Choose the Best EMS Unit?

Choosing the best EMS unit involves taking into consideration a few important factors that help you analyze the quality and quantity of results that the EMS unit might give you. Here are a few important points you should look at before choosing the best EMS unit for yourself.

Intensity Controls

The intensity of the electrical impulses is paramount in deciding the best EMS unit for you. The intensity of the EMS unit directly translates to the intensity of the electrical impulses that will be delivered to the muscle. The greater the intensity of the electrical impulses the faster will the unit work, but if the intensity exceeds a specific limit it can cause injuries as well.

Channels Available

Channels in an EMS unit are referred to as the number of electrodes that can lead as outlets from the EMS unit. A single channel EMS unit can have two electrodes attached to it whereas a dual-channel EMS unit can be exceeded to four electrodes. The area of treatment and the intensity required can be the criteria for choosing a single channel or dual channel EMS unit.

Treatment Time

Some EMS units have a treatment timer set within the unit to ensure that no complications occur due to elongated use of the electrical impulses. Depending on the condition you are treating and the intensity prescribed to you by the medical professional you can choose the EMS unit that is either for shorter treatment times or longer treatment times.

Other Important Factors

These include battery-powered or rechargeable EMS units, compact or tabletop EMS units, portable or stationary EMS units, and lightweight or standard weight EMS units.
