EXPLANATION OF EMS
Electrical Muscle Stimulation (EMS) is an internationally accepted
and proven way of treating muscular injuries. It works by sending
electronic pulses to the muscle needing treatment; this causes the
muscle to exercise passively. It is a product derived from the square
waveform, originally invented by John Faraday in 1831. Through
the square wave pattern it is able to work directly on muscle motor
neurons. This device has low frequency and in conjunction with the
square wave pattern allows direct work on muscle groupings. This
is being widely used in hospitals and sports clinics for the treatment
of muscular injuries and for the re-education of paralyzed muscles,
to prevent atrophy in affected muscles and improving muscle tone
and blood circulation.
How does EMS work?
The EMS units send comfortable impulses through the skin that stimu-
late 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 is
repeated.
The goal of electrical muscle stimulation is to achieve contractions or
vibrations in the muscles. Normal muscular activity is controlled by
the central and peripheral nervous systems, which transmit electri-
cal signals to the muscles. EMS works similarly but uses an exter-
nal source (the stimulator) with electrodes attached to the skin for
transmitting electrical impulses into the body. The impulses stimulate
the nerves to send signals to a specifically targeted muscle, which
reacts by contracting, just as it does with normal muscular activity.
Possible EMS application
Generally the Promed EMT-6 shall be used for the following medical
indications or the following complaints as a EMS unit for treatment:
• For relaxation of muscle spasm
• For increase of blood circulation
• For prevention of retardation of disuse atrophy
• For muscle re-education
