EMS questions and answers

What is EMS and how does it work?

EMS stands for Electrical Muscle Stimulation (sometimes also called Electronic Muscle Stimulation). One might think that electrical muscle stimulation was something new, but it has in face been used by physiotherapists, athletes and those who train regularly for many years to build up muscles, for training and rehabilitation. They know that they will achieve results faster if they use EMS in combination with normal training. CEFAR Medical has been developing electrotherapy devices since 1975. Medical research has always been the basis for their products, including the sport and fitness models.

Can anyone use EMS?

Pregnant women should avoid using electrical stimulation during the first trimester (the first 12 weeks of pregnancy). People with implanted electronic equipments such as pacemakers and intracardial defibrillators must not be treated with electrical stimulation.

Is it really possible to train muscles with EMS?

Yes. EMS increases the strength and muscle mass of your muscles just like other types of training. You will achieve the best effect by combining EMS with active training.

How often should you train with EMS?

We recommend using EMS 2-6 times per week and muscle, depending on what sort of program is used, and your training level.

How long should I use EMS?

Each stimulation session can be from 5 minutes up to an hour long, depending on the program you select. The times are preset so you don’t need to worry about determining the time yourself.

Can I improve my condition using EMS?

No. You need to do some form of training/exercise that increases your heart rate to improve your condition, such as cycling or jogging.

Can EMS help me to slim?

EMS is not a slimming method, but just like other forms of training, EMS makes your muscles stronger and firmer.

How do I know where to apply the electrodes?

Apply two or more electrodes on the muscle you want to train. For pain relief, apply the electrodes to the area where you have pain and select a pain relief program. The user guide includes images for each program showing you where the electrodes should be placed.

How long before I need to replace the electrodes?

The electrodes can be used for 20-40 applications and removals, depending on how well you follow the care and storage instructions. These instructions are included in the electrode packaging. You can purchase new electrodes from Tensway at any time.

How strong should the stimulation be?

For muscle training, the stimulation should be strong enough to cause muscle contractions. During warm-up and recovery programs, the muscles should vibrate. At no time should be stimulation feel painful. The user guide describes how each program should feel.

Is the current used harmful?

No. The current is so weak that it is not harmful at all. EMS and similar machines are used by physiotherapists and doctors on their patients.

What sorts of batteries are used?

Normal 1.5 V batteries that can be purchased in any supermarket. You can also use rechargeable 1.5 V batteries.

What is the difference between products sold on TV and Cefar products?

We cannot make any statements that cover all products sold on TV, but we have tested some of them. There is a big difference in the technical design of the programs, which is important in terms of muscle physiology. It has implications not only on the effect you are trying to achieve, but also whether or not the stimulation is pleasant. In addition, the quality of the hardware varies, particularly in relation to how durable the product is.

Are Cefar EMS machines EU approved?

Yes. Cefar’s stimulators meet the requirements of the Medical Device Directive (MDD 93/42/EEC), including the EMC requirements. Cefar is certified under ISO 9001 and EN 46001 standards.
