Combination Therapy At Its Best

Combination therapy is designed for the combined simultaneous application of therapeutic ultrasonic energy and electrical stimulation through the transducer.

SynchroSonic U/HVG50
Three widely used therapeutic modalities are provided by the U/HVG50: low voltage galvanic (de) stimulation, high volt stimulation, and ultrasound.
Low voltage galvanic (de} allows the practitioner to conduct denervation testing or to perform iontophoresis applications. High-volt stimulation produces no heat under the electrodes and therefore causes less tissue irritation. Ultrasound allows for increased cell permeability with greater metabolic exchange across the cell wall. While providing micro massage to the patient, the ultrasound produces an analgesic and thermal effect when applied to the nerve root and primary treatment site.
Each of the three modalities may be applied separately or the ultrasound may be combined with either low voltage galvanic (de) or high volt stimulation simultaneously through the ultrasound transducer.

Optional Accessories
For greater convenience, this top-of-the-line full-range combination therapy unit can be easily wall-mounted or placed on our three-shelf, high impact plastic utility cart.
