In addition to the base Inter D74, available are also three additional versions featuring waveforms and therapy programs available in other D6 series units. These include

• INTER D74 & STIM
• INTER D74 & TENS
• INTER D74 & STIM & TENS

In common with the basic unit, the above variants 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.

INTER D74 & STIM

As compared with the basic unit, the INTER D74 & STIM adds the following groups of waveforms (borrowed from the STIM D75):

• pulsed currents,
• medium frequency pulsed currents,
• tonolysis.

Detailed list of waveforms generated by the Madyn D61 & STIM (in bold type - those absent from the basic variant).

• galvanic currents: galvanic continuous and intermittent,
• pulsed currents: triangular and rectangula r,
• medium frequency pulsed currents: with triangular, sinusoidal, rectangular envelopes (each envelope type available as unipolar or bipolar) ,
• Kotz' current (Russian stimulation),
• modulated current 4000 Hz,
• Trabert's current,
• interferential currents: Nemec's, isoplanar, dipole, bipolar,
• microcurrents (unipolar and bipolar).

The number of therapy programs is 62 (in the basic variant - 61)

Inter D74 & TENS

Additional features available in the Madyn D74 & TENS include a group of TENS therapies derived from the TENS D77.

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

• galvanic currents: galvanic continuous and intermittent,
• Kotz' current (Russian stimulation),
• modulated current 4000 Hz,
• Trabert's current,
• interferential currents: Nemec's, isoplanar, dipole, bipolar,
• TENS currents: symmetrical, asymmetrical, symmetrical-interval, modulated, burs t,
• microcurrents (unipolar and bipolar).

The number of therapy programs is 76 (in the basic variant - 61)

INTER D74 & STIM & TENS

Further capabilities of the Inter D74 & Stim & TENS versus the Inter D74 include selected groups of waveforms taken from the Stim D75 and the TENS D77:

• pulsed currents,
• medium frequency pulsed currents,
• tonolysis,
• TENS therapy.
