Some electrostimulators combine electrical impulses with mechanical vibrations. This function generates physical vibrations that act on tissues concurrently with electrical stimulation. The main purpose is to promote the release of muscle tension, improve local blood circulation, and provide a massage effect. Users can typically adjust various intensities and rhythms of vibrations according to their needs. Vibrations thus complement and extend the effects of basic methods such as TENS (Transcutaneous Electrical Nerve Stimulation), used for pain relief, or EMS (Electrical Muscle Stimulation), designed for muscle strengthening and regeneration. The combination of these methods can make the overall therapy more effective.
