These are specialized programs within electrostimulators, designed for the relief or prevention of muscle cramps. Using weak electrical impulses applied via electrodes to the skin, the device stimulates the affected muscle area. This stimulation helps to relax the contracted muscle and can also interrupt pain signals traveling to the brain, thereby providing relief. Regular use of these programs can also serve as a preventive measure, as it promotes blood circulation in the muscles and reduces their susceptibility to cramps. It often utilizes the principles of Transcutaneous Electrical Nerve Stimulation (TENS), which focuses on nerve fibers and blocks pain perception, or Electrical Muscle Stimulation (EMS), which directly affects muscle fibers and aids in their relaxation.
