INTRODUCTION TO EMS
HOW EMS WORKS
1. Relaxation of muscle spasms
2. Prevention or retardation of disuse atrophy
3. Increasing local blood circulation
4. Muscle re-education
5. Immediate post-surgical stimulation of calf muscles to prevent venous thrombosis
6. Maintaining or increasing range of motion
The EMS units send comfortable impulses through the skin that stimulate the nerves
in the treatment area. When the muscle receives this signal it contracts as if the brain
has sent the signal itself. As the signal strength increases, the muscle flexes as in
physical exercise. Then when the pulse ceases, the muscle relaxes and the cycle
starts over again, (Stimulation, Contraction and Relaxation.)
CONTRACTION / RELAXATION
The contraction time and relaxation time of EMS are adjustable. Stimulation will
commence at the contraction setting time and cease at the relaxation setting time.
Then the cycle starts over again, Stimulation, Contraction and Relaxation.
RAMP
In order to achieve a comfortable exercise and avoid discomfort because of
immediate current onset, each contraction may be ramped so that the signal comes
on gradually and smoothly. The intensity of electrical current will reach the set level
within the Ramp time. It will NOT reach the desired level if the ramp time is greater than
the total contraction time.
OUTPUT MODE
The output of both channels is adjustable. Stimulation can be synchronous or
alternate. Stimulation of both channels will occur at the same time when the
asynchronous pattern is selected. In alternating mode, the stimulation from CH2 will
occur after a contraction of CH1 is finished.
