is a high-tone therapy device used in home therapy. Its current forms and parameters have been optimally developed for muscle stimulation in the treatment of diabetic polyneuropathies. In addition to the metabolism-promoting effect so typical of this new type of therapy, muscle stimulation that is particularly pleasant for the patient is achieved. HighTone Therapy works with medium-frequency, specially modulated alternating current forms. Studies have shown that this new form of therapy brings about a significantly greater improvement in diabetic polyneuropathies than conventional forms of electrotherapy.
