Human brain sends weak signals to the relevant muscle groups, allowing the muscles to contract and relax before every movement in daily life. In some cases the muscle cannot be stimulated due to nerve damage or when the muscle decreases and loses its strength due to lack of use. Specifically for such physiotherapy purposes, the brain's electrical currents are transmitted to the muscles in a controlled manner from outside, allowing them to be stimulated. Finally the muscles contract and relax; by the help of that the loss of muscle mass is prevented. ProBody Systems improved that technology with new wearable EMS machines and equipment; the whole body has taken on a new dimension via EMS together with the new generation of clothing. ProBody Systems EMS is a system stimulating the 10 main muscle groups in the body with currents of certain frequencies by its specially designed EMS suit and electrodes. The torso muscles which are difficult to operate in a standard workout and especially the inner corseting (core) muscles keeping the spine upright, both can be operated with only 25 minutes of training by the means of wearable whole-body EMS device.
