Manufacturer's Description:

The Amrex Z-Stim IF250 microprocessor controlled stimulator provides three widely used modalities: Quad-Polar interferential, Bi-Polar interferential and Russian stimulation. Interferential current is designed for therapeutic stimulation of nerves and muscles in the treatment of acute pain, edema reduction, and muscle rehabilitation. The Quad-Polar Interferential modality provides twelve selectable beat frequencies - six constant and six sweep. The Quad-Polar modality features a dynamic output cycle which increases the interferential stimulation target field. The Bi-Polar Interferential modality provides premodulated, four pad, two channel interferential treatment. The Bi-Polar modality features twelve selectable modulation frequencies - six constant and six sweep. The Russian (2500 Hz) modality provides four pad, two channel Russian stimulation featuring a continuous, exercise or rehab treatment mode. The IF250 features a treatment stop switch designed to instill patient confidence. The treatment stop switch allows the patient to discontinue stimulator output at the press of a button.
