There is no most professional if physiotherapy instrument in this industry, but it is relatively more professional. Anyone who says he is the most professional if physiotherapy instrument must be a fool. I have used Beyikang ZP- 100DIIB intermediate frequency physiotherapy instrument, which supports the adjustment of 198 files, and finely controls the current of each file to be only 0.5mA, so the user can't feel the subtle change of current at all, but the comfort and curative effect are quietly changing. Beiyikang ZP- 100DIIB intermediate frequency physiotherapy instrument has 35 clinical prescriptions, which are described in detail in its product instruction manual. It is clear at a glance which disease should be modulated to which waveform and which gear. I think it's quite convenient. I wonder if the operator meets your professional requirements.
