  • Diadynamic according to Bernard, types DF, MF, RS, MM, CP, LP, CPiso, LPiso (with sequence setting)
  • Paresis stimulation (medium frequency currents in shape of triangle, rectangle, sine and trapezoid – each unipolr and bipolar
  • Spastic paresis stimulation in double-channel mode (tonolysis)
  • TENS, including so called "irritating" modulation
  • HVPS stimulation
  • Kotz current (Russian stimulation
