High-Intensity Focused Electro-Magnetic field technology which has the ability to induce supramaximal muscle contractions.The rapidly changing magnetic field induces electric currents in the tissue where it depolarizes neural membranes and governs motor units in the target muscles, causing concentric contractions. 3,4 The effects are highly selective; due to its physiological characteristics only motor neurons are activated, while other neurons or tissues are not responsive to the current, and therefore stay unaffected.
