Introduction to the MTZ-G Computer Medium Frequency Electrotherapy Machine

This series of electrotherapy machines uses a square wave current with a medium frequency of 2000-8000 Hz. This type of current offers many advantages, such as reduced tissue resistance, strong penetration, and deep action. However, a constant-amplitude medium frequency current, due to its lack of amplitude variation, is easily adapted to by the human body and cannot excite muscles as its frequency exceeds the therapeutic range (0-150 Hz). To retain the benefits of medium frequency while incorporating low-frequency characteristics, a low-frequency (1-150 Hz) modulated medium frequency current is employed. This causes the amplitude of the medium frequency current to vary with the low-frequency current, combining the advantages of both medium and low frequencies.

☆ Six benefits of modulated medium frequency:

☆ Low-frequency modulated medium frequency is non-electrolytic

☆ Low-frequency modulated medium frequency has strong penetration

☆ Low-frequency modulated medium frequency has a comprehensive effect on the nervous system

☆ Low-frequency modulated medium frequency provides pain relief and exercises skeletal muscles

☆ Low-frequency modulated medium frequency promotes local blood circulation

☆ Low-frequency modulated medium frequency stimulates human cells

㈡ Diversity of pulse-modulated medium frequency

The low-frequency pulse waves of this machine include: square wave, triangular wave, exponential wave, trapezoidal wave, sawtooth wave, and sine wave. These modulate the 2000-8000 Hz medium frequency fundamental wave, creating various modulated medium frequency waves.

Output comes in multiple forms: constant amplitude, continuous amplitude modulation, intermittent amplitude modulation, alternating amplitude modulation, and dynamic ternary variations in modulation frequency, waveform, and amplitude.

It offers multiple treatment methods: multi-step programmed therapy, audio frequency electrotherapy, pulse-modulated medium frequency electrotherapy, sine-modulated medium frequency electrotherapy, planar interference electrotherapy, and pulsating DC drug iontophoresis.
