Amrex Synchrosonic Single Channel Combination Unit US-50
Combination Ultrasound / Low Volt AC Muscle Stimulator

Combination therapy plays an important role in today's modern practice. It allows for the expansion of the treatment capabilities by combining therapeutic ultrasound with low volt muscle stimulation. It enables the practitioner to take full advantage of the thermal effect of the ultrasound in combination with the analgesic effect of stimulation.

The SynchroSonic US/54 is a versatile combination unit that provides muscle stimulation with four pad application and therapeutic ultrasound. Each modality may be used independently or in combination through the lightweight ultrasound transducer. The custom designed transducer is available with standard size faceplate and/or small site faceplate and features a protection switch and cable fault alarm system. The optional QuickConnect Transducer Cable System allow the practitioner to replace the transducer cable on site.

The US/54 also features the patient treatment stop switch. Designed to promote patient assurance, the treatment stop switch allows the patient to discontinue stimulator output at the press of a button.

SynchroSonic US/50 combination ultrasound / low volt AC stimulator provides muscle stimulation with two pad application, therapeutic ultrasound and a patient treatment stop switch.
