INTRODUCTION TO EMS
There is nothing "magic" about Transcutaneous Electrical Nerve Stimulation (TENS). TENS is intended to be
used to relieve pain. The TENS unit sends comfortable impulses through the skin that stimulate the nerve
(or nerves) in the treatment area. In many cases, this stimulation will greatly reduce or eliminate the pain
sensation the patient feels. Pain relief varies by individual patient, mode selected for therapy, and the type of
pain. In many patients, the reduction or elimination of pain lasts longer than the actual period of stimulation
(sometimes as much as three to four times longer). In others, pain is only modified while stimulation actually
occurs. You may discuss this with your physician or therapist.
EXPLANATION OF EMS
Electrical Muscle Stimulation 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. The EMS has low frequency and this
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 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.) Powered muscle stimulators should only be used under medical
supervision for adjunctive therapy for the treatment of medical diseases and conditions.
