Amrex SynchroSonic US-752 Combination Ultrasound and High Volt Muscle Stimulator

When a single modality is not enough, the Amrex SynchroSonic US-752 delivers two in one. This professional-grade combination unit pairs therapeutic ultrasound with high volt muscle stimulation, allowing practitioners to treat muscle rehabilitation, atrophy prevention, pain management, and edema reduction — either as separate modalities or simultaneously through the ultrasound transducer. The intuitive panel design keeps treatment management precise and accessible: selectable frequency range, independent on/off surge duration, and selectable pulse width give the clinician full control over each session. The bipolar application eliminates the need for a single large dispersive electrode, and the patient treatment stop switch allows the patient to discontinue stimulator output at any time for added safety. The sealed, ergonomically designed soundhead supports underwater therapy applications.

Frequently Asked Questions

What is the advantage of combining ultrasound and high volt stimulation in one unit?
Using both modalities simultaneously through a single transducer allows the practitioner to deliver the deep tissue effects of therapeutic ultrasound — increased circulation, tissue extensibility, and cellular activity — at the same time as the neuromuscular effects of high volt stimulation, such as pain modulation, muscle re-education, and edema reduction. This combined approach can reduce treatment time compared to applying each modality separately, and the simultaneous delivery through the soundhead means both effects are targeted to the same tissue area.

What does bipolar application mean and why does it matter?
In a bipolar configuration, both the active and dispersive electrodes are located close together — in this case, delivered through the ultrasound transducer itself. This eliminates the need to place a separate large dispersive pad on a distant body part, which simplifies setup, improves patient comfort, and allows more precise targeting of the treatment area. It is particularly useful when treating smaller or anatomically complex areas where placing a large dispersive electrode would be impractical.

What output modes are available and when are they used?
The US-752 offers four output modes: pulsation (intermittent on/off cycling for gentle stimulation), tetanize (sustained contraction for muscle strengthening), surge (gradually increasing intensity for comfortable muscle recruitment), and reciprocal (alternating stimulation between muscle groups for balanced treatment). The appropriate mode depends on the treatment goal — pain management, muscle re-education, edema reduction, or strengthening — and should be selected based on the clinician's assessment and the patient's tolerance.

Is the soundhead suitable for underwater ultrasound therapy?
Yes. The soundhead is sealed and designed for underwater application, which is useful when treating areas that are difficult to contact directly with the transducer — such as the hands, feet, or ankles — by submerging the body part and soundhead in water. Water acts as a coupling medium in place of ultrasound gel. The optional 1.5" small soundhead is particularly well-suited for underwater treatment of smaller anatomical areas.
