In addition to the base D75, available is also additional versions featuring waveforms and therapy programs available in TENS D77 unit. This is

• STIM D75 & TENS

In common with the basic unit, the above variant feature twin independent therapy channels, waveform generation in CC and CV modes (constant current and constant voltage, respectively) and automatic electrodiagnostics (drawing an I/t curve). Here you can find a list of important differences which include the list of waveforms generated and the number of therapy programs.

STIM D75 & TENS

As compared with the basic unit, the STIM D75 & TENS adds the following groups of waveforms (borrowed from the TENS D77):

Detailed list of waveforms (in bold type - those absent from the basic variant).

• galvanic currents: galvanic continuous and intermittent,
• pulsed currents: triangular and rectangular,
• medium frequency pulsed currents: with triangular, sinusoidal, rectangular envelopes (each envelope type available as unipolar or bipolar),
• tonolysis: triangular, sinusoidal, rectangular envelopes (each available as unipolar or bipolar),
• Kotz' current (Russian stimulation),
• modulated current 4000 Hz,
• Trabert's current,
• TENS currents: symmetrical, asymmetrical, symmetrical-interval, modulated, burst ,
• microcurrents (unipolar and bipolar).

The number of therapy programs is 52 (in the basic unit - 38).
