Chapter 1 : INTRODUCTION
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. 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 reeducation of paralyzed muscles, to prevent atrophy in affected muscles and improving muscle tone and blood circulation.
HOW EMS WORKS
EMS is intended to be used to increase blood circulation and loosens tight and
knotted fibers, stimulates muscle growth and also reduces stiffness in muscle
joints. 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.)
Chapter 2 : CAUTIONS
1.Precautions:
Isolated cases of skin irritation may occur at the site of electrode placement
following logn-term application. Effectiveness is highly dependent upon patient
selection by a person qualified in the management of pain patients.
2.Contradictions:
EMS devices can affect the operation of demand type cardiac pacemakers.
EMS is not recommended for patients with known heart disease without physical evaluation of risk. Do not use EMS on the carotid sinus(neck) region. Do no
apply EMS for undiagnosed pain syndromes until etiology is established. Do
not stimulate on the site that may cause current to flow transcerebrally(through
the head).
3.Adverse Reactions
Possible allergic to gel, skin irritation and electrode burn are potential adverse
reactions.
4.Read operation manual before use of EMS.
5.We emphasize that patient with an implanted electronic device (for example, a
pacemaker) should not undergo EMS treatment without first consulting a doctor.
The same applies to patients with any metallic implants.
6.If EMS therapy becomes ineffective or unpleasant, stimulation should be discontinued until its use is reevaluated by the physician or therapist.
7.Avoid adjusting controls while operating machinery or vehicles.
8.Turn the EMS off before applying or removing electrodes.
9.EMS devices have no AP/APG protection.
Do not use it in the presence of explosive atmosphere and flammable mixture.
Chapter 3 : WARNINGS
1.Caution should be used in applying EMS to patients suspected of having
heart disease. Further clinical data is needed to show there are no adverse
results.
2.The safety of EMS devices for use during pregnancy or birth has not been
established.
Do not use EMS during pregnancy.
3.EMS is not effective for pain of central origin. (This includes headache.)
4.EMS devices should be used only under the continued supervision of a
physician.
5.EMS devices have no curative value.
6.EMS is a symptomatic treatment and as such suppresses the sensation of
pain which would otherwise serve as a protective mechanism.

7. Electronic monitoring equipment (such as ECG monitors and ECG alarms)
may not operate properly when EMS stimulation is in use.
8. There should be a prominently placed statement warning that stimulus
delivered by this device may be sufficient to cause electrocution. Electrical
current of this magnitude must not flow through the throax because it may
cause a cardiac arrhythmia.
9. Do not place electrodes on the front of the throat as spasm of the Laryngeal
and Pharyngeal muscle may occur.
10.Care should be taken so that when operating potentially dangerous machinery the stimulator controls are not changed abruptly.
6. Electrodes should not be placed over the eyes, in the mouth, or internally.
11. Keep this device out of the reach of children.
12.Caution: Federal law restricts this device to sale by or on the order of a
physician.
Chapter 4 : GENERAL DESCRIPTION
The AMS-4 EMS is a battery operated pulse generator that sends electrical
impulses through electrodes to the body and reaches the underlying nerves or
muscle group. The device is provided with two controllable output channels,
each independent of each other. An electrode pair can be connected to each
output channel.
The electronics of the AMS-4 EMS create electrical impulses whose Intensity,
Pulse Width, Pulse Rate, Contraction, Relaxation and Ramp may be altered
with the switches. Dial controls are very easy to use and the slide cover prevents accidental changes in the setting.
