EMS is not recommended for patients with known heart disease without physi-
cal 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 dis-
continued 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.
Chapter 1 : INTRODUCTION
EXPLANATION OF EMS
Electrical Muscle Stimulation is an internationally accepted and proven way of treat-
ing 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 Fara-
day 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 re-
education of paralyzed muscles, to prevent atrophy in affected muscles and im-
proving 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 con-
tracts 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.
