EXPLANATION OF EMS

Elec tri cal Musc le Sti mula tion is a n inter nationally acc epted and
pro ven wa y of t reat ing mu sc ul ar injur ies . I t w ork s b y sendin g
electroni c pulses to the muscle needing treatment; this causes th e
mus cle to exerci se pass ively.

It is a product derived from the squ are waveform, origi nally invented
by Joh n Farad ay in 18 31. Th rough the squar e wave pat tern it is
able

to work directly on muscle motor neurons. The AGF-6X2 Digital
EMS has l ow fr eque ncy and th is in c onjunction wi th the square
wave p att ern allow s d ir

ect work o n mu sc le g roupings . T his is
being widely us ed in hosp itals and s ports clin ics for the treatment
of mu scular injuries and for the r e-educati on of paralyzed musc les,
to pr event atr ophy in aff ected muscl es an d improving mu scl e tone
and bl ood c ircu lation.

HOW EMS WORKS

1. Relaxati on of mus cle spas ms

2. Preven tion or retar dation of dis use atrop hy

3. Incr easing local blood circ ulation

4. Mus cle re-ed ucat ion

5. Immediat e pos t-sur gical s timul ation of c alf muscl es to prevent

venous thr ombos is

6. Maintaining or i ncreasi ng r ange of motion

The EMS un its s end comf ortable impul ses th roug h the s kin th at
st imul ate t he n erves i n t he t reatme nt area. W hen th e mus cle
receives this si gnal it contrac ts as i f the brai n has s ent the s ignal
its elf . A s the

sig nal s tren gth in cre ases , t he musc le f lexes as in
physical exercise. T hen when the pulse ceases, the mus cle relaxes
and t he c ycl e st arts over agai n, ( St im ulat ion , C ont rac tio n and
Relaxation.) Powered muscle stimulators should only be us ed under
medi cal s upervi sio n fo r adj unc tive ther apy f or th e tre atmen t of
medical diseas es and c onditions .

MPORTANT SAFETY INFORMATION!

Read instruction manual bef ore operation. Be s ure to comply with
all “CAUT IONS” and “W ARNINGS” i n the manual. Failure to f ollow
instructions ca n c aus e har m to us er or device.

Chapter 2: CAUTIONS

1. Federal law (USA) rest rict s t his devic e t o s ale by or on the
order of a physic ian

2. Safety of powered muscle s timulators for use during pregnancy
has not b een establi shed.

3. Caution should be used for patients with suspected or diagnosed
heart problem s.

4. Caution should be used for patients with suspected or diagnosed
epile psy .

5. Cauti on s hould be used in the pre senc e of the following:
a. Wh en t here is a ten dency to hemorrh age f ollowing ac ute

traum a or f racture;

b. Followin g r ecent s ur

gica l p roc edures wh en musc l

e

cont racti on m ay di srupt the healin g pr oces s;
c. Over the menst ruatin g or pregnan t uterus ; and
d. Over ar eas of the skin which lack normal s ensation.

6. Some p atients may experi ence skin irritation or hypers ensi tivity
due to th e electri cal s timulation or electric al cond uctive medium.
The irritation can usually be redu ced by usi ng an altern ate
conduc tive medium, o r alt ernate elect rode p lacemen t.

7. Elect rode plac ement and s timulat ion s etting s s houl

d be b ased

on th e gui dance of the p rescr ibing practi tion

er.

8. Powered muscl e st imul ators shoul d be kept out of the r each of
child ren.

9. Powered mu scle stimulat ors should b e used only with the leads
and electr odes recommen ded for use by the m anuf actur er.

10.Port able p owered muscl e s timul ators shou ld not be used while
driving , operating mac hiner y, or duri ng any ac tivity in which
involunt ary muscle c ontr action s m ay put the user at undue
risk of injury .

hapter 3 : WARNINGS

1. The long-term effec ts of c hron ic el ectri cal stimu lation are
un kno wn.

2. Stimulat ion sh ould n ot be applied over t he carotid sinus nerves,
parti cular ly i n pat ients wit h a known sens itivity to the carotid
sinu s ref lex.

3. Stimulation shoul d not be applied over the neck or mouth. Severe
spasm of t he laryngeal and ph aryngeal muscles may occ ur and
the contr acti ons may be str ong enough to clos e t he ai rway or
cause diff iculty in breat hing.

4. Stimulation should not b e applied tran sthor acically in that t

he

introduction of elect

rical c urrent int o the heart may cause card iac

arrh ythmia s.

5. Stimulation should not be applied transcer ebrally.

6. Stimulatio n s hould not be appl ied over swollen, i nfec ted, or
inflamed areas or sk in eruptions, e.g., phlebitis, t hrombophlebitis,
varic ose vein s, etc .

7. Stimulati on s hould n ot be applied over, or in proximity to,
canc erou s lesi ons .

Chapter4: CONTRAINDICATION

Powered mus cle sti mulat ors sh ould not be used on patients wit h
card iac demand pacem akers.

Chapter 5: ADVERSE REACTIONS

Skin irrit ation and burns b eneath the elec trodes h ave been reported
with the use of powered mu scle stimulators. If skin irritat ion occu rs,
disc onti nue use and c ons ult your ph ysic ian.

Chapter 6: GENERAL DESCRIPTION

The EMS is a battery oper ated puls e generator
that sends elect ric al impu lses throu gh electrodes to the body and
reac hes the u nder lyi ng n erves or mus cl e gro up. T he d evic e is
provided with two c ontrollab le output channe ls, each indepen dent
of each other. An electrod e pair can b e c onnec ted to eac h ou tput
