HF54 Interferential/Premod Regular $2599 Now $2350 Direct Only Add Hands-Free Ultrasound for $595

Interferential therapy uses a four-electrode application. These four electrodes deliver two currents. When the two paths cross, they result in a “beat frequency”. This “beat frequency” results in a lowered skin resistance (impedance) thus it is more comfortable and a more tolerable penetration into the skin compared to low frequency currents. Premod is a composite waveform using two frequencies similar to interferential. Premod is used with 2 electrodes on smaller areas when interferential cannot be used or in combination with ultrasound. Premod can be used at two different intensities or on two different patients.
