SYNERGY IS THE ONLY DEVICE DELIVERING BOTH LOW AND HIGH FREQUENCY MAGNETIC FIELDS. Further to the most traditional frequencies from 1 to 200 Hz, it is also possible to set 2 GHz high frequency magnetic field. It is possible to set only low frequency or only high frequency, but it is also possible to combine the two frequencies for getting the benefits of both the magnetic fields. Usually, low frequency magnetic field is applied for performing treatment in case of fractures, pseudarthrosis, osteoporosis, etc.. The aim of the treatment is to improve quality and quantity of callus and collagene. Otherwise, high frequency magnetic field is generally used for treating vascular, dermatology diseases and also for treating all the pathologies where warm is absolutely contra-indicated.
