The Limfa Therapy System is a medical device, intended for stimulation with extremely low frequencies (ELF), pulsed, and low frequency (ELF 3-300 Hz) magnetic fields, which generates pulsed, bipolar and variable electromagnetic fields, at very low and variable intensity and frequency using complex waveforms (sinusoidal, triangular and rectangular), thus obtaining multiple signals within a frequency spectrum composed of base waves from 2 to 80 Hz plus the harmonics that are produced by the hardware component. The manufacturer presets base wave frequencies and the harmonics are generated by the DM hardware. The therapy is based on the generation of a pulsed magnetic field with a very low and variable frequency and variable intensity.
An electrically-powered device assembly intended to apply various modes of electrical stimulation transcutaneously to treat/prevent neuromuscular symptoms and disorders typically as a form of physical therapy [neuromuscular electrical stimulation (NMES)/electronic muscle stimulation (EMS)]; it may in addition be intended for transcutaneous electrical nerve stimulation (TENS) to treat pain, and/or electroacupuncture. It includes an electric current pulse generator and noninvasive electrodes; it is not intended for tremor suppression. Clinical applications typically include relaxation/re-education of muscles, prevention of muscle atrophy, and improvement of blood circulation.
