MS324A Low Volt AC Muscle Stimulator

MS324A, MS324AB Low Volt AC Stimulators The MS324 and MS324AB are designed for the application of low-volt ac muscle stimulation. The MS324A and MS324AB ar dual channel, four pad. low volta e electrical muscle stimulators th t produce pulsation. tetanize, surge, and reciprocal output. Tl1e MS324A and MS324AB feature the p tient treatment top switch Designed to promote patient assurance, the treatment stop switch allows the pat, en to discontinue st1 emulator output at the press of a button.
For portability, or when ac power is unavailable. the MS324AB utilizes an internal rechargeable b battery power supply.

MS322 Low Volt AC Muscle Stimulator
The MS322 Low Volt AC Muscle S simulator combines proven reliability and ac power in a compact low-volt ac muscle stimulator. The MS322 is a single channel, two pad, low voltage electrical muscle stimulato1 that produces pulsation tet is and surge output.

Combination Therapy
The MS324A, MS324AB, and MS322 may be used for combination therapy. Low voltage electrical muscle stimulation may be applied se irately or 11 may be combined with w1 h  therapeutic ultrasound simultaneously through the ultrasound transducer of an Amrex SynchroSoni U/50.
