The MS324A is designed for the application of low volt AC muscle stimulation. The MS324A and its sister device, MS324AB, are dual-channel, four-pad, electrical muscle stimulators that produce low voltage surge, pulsation, tetanize, and reciprocal output.

What helps the MS324A stand apart is the patient stop switch. For the patient's own assurance, it has the ability to discontinue the stimulator output at any time by simply pressing a button. This lowers any discomfort for the patient, allowing for some control.

This device is also typically combined with Amrex ultrasound devices for well-rounded combination therapy treatments. Low voltage electrical muscle stimulation may be applied separately or it may be combined with therapeutic ultrasound simultaneously through the ultrasound transducer of a SynchroSonic U/50.

The MS324A Muscle Stimulator weighs approximately 4.5 lb, but comes equipped with a convenient handle for easy portability and placement. It can also be wall mounted for convenience in the treatment room.
