Portable Digital EMS: A must have device for your patients!

The Portable Digital EMS with Timer and Carrying Case helps in muscle re-education as part of physical therapy and rehabilitation. This is a device that you can have at your clinic or recommend your patients to buy.  Electrical Muscle Stimulation is a time-tested, tried-and-true method for treating muscle injuries. It works by passively exercising muscles via the transmission of comfortable electronic impulses.


·         Includes carrying case, 2 lead wires, 9-volt battery, 1 package of 4 pre-gelled electrodes, metal belt clip, and instruction manual.

·         Contraction time adjustable from 1 to 30 seconds.

·         Digital wave technology.

·         Efficient delivery of the wave signal.

·         Dual isolated channels.

·         Pulse Amplitude: 0-90mA peak to peak into 500 ohm load.

·         Pulse frequency adjustable from 1-150 Hz.

·         Pulse width adjustable from 30 uS ~ 260 uS, 10 uS/step.

·         Ramp time adjustable from 1 to 6 seconds.

·         Relaxation time adjustable from 1 to 30 seconds.


The stimulation, contraction, and relaxation cycle loosens muscle fibers, promotes blood flow and stimulates muscle growth. It is pretty much what it says on the tin; the muscle contracts when it receives the signal from the EMS device, it flexes when the strength of the signal increase, and relaxes when the electrical impulse stops – and then the cycle starts over again. And it all occurs as if the brain itself has command it.


Warn your patients that isolated cases of skin irritation may be experienced at the site of electrode placement following prolonged application. Potential adverse reactions include allergy to gel, skin irritation and electrode burn.
