The “Spiegel” reported last week about the fact that frequencies hepl against muscle cramps. Researchers think they found something new (http://www.spiegel.de/gesundheit/ernaehrung/kraempfe-ausloesen-von-muskelkraempfen-koennen-sie-verhindern-a-987259.html). However this is not new! We from the Atlaspraxis have been working successfully with the biomechanical muscle stimulation by Prof. Dr. Nazarov to release tension and prevent muscle cramps. The biomechanical muscle stimulation operates with frequencies and is based on decades of research.
