BioStim® NMS2 – Digital Muscle Stimulator (E-Stim)

The BioStim® NMS2 is extremely flexible, powerful, comfortable and user friendly! Functions like a T.E.N.S. in constant mode to achieve pain relief. But its biggest contribution is its muscle contracting stimulation boasting one of the highest pulse widths in its class. An impressive 400 µS is high enough to pull some of the largest muscles in professional sports.

Customize your patient’s therapy by adjusting the Ramp-ON, Peak-ON, and Ramp OFF to support your therapy regimen. The patient or therapist can easily toggle from pain relief settings, to a muscle strengthning program with the push of one button. Adjustable Constant, Cycled and Reciprocal open programs. (Holds custom settings).

There are (8) user friendly pre-set therapy settings to accommodate a wide population range from pediatric applications to professional athletes. The device holds up to three custom programs and it is easy for the patient to toggle between them. The custom programs remain set into the device until they are changed or reset.

The Patient Compliance meter starts recording how many hours the device has been used from the first time it is issued to the patient, until the device is reset by the dealer or therapist. The adjustable pulse width setting enables patients of all tolerance levels to achieve success in their rehab program.
