ELECTRONIC MUSCLE STIMULATION (EMS)
EMSisthe process of using veryweak electricalimpulses to contract and relaxmuscles. It produces
"passive" exercise by sendingelectricalimpulses or signals tothe selected muscle or musclegroups
to contract and relaxthem. In "active" exercise the signals are sent bythe brain. Itisnot new; it
has beenused for hundreds of years.However,modern scientific developments in suchspecialized
EMS medicalresearchcenters asthe Rehabilitation EngineeringSection of Rancho Los Amigos
Hospitalnear Los Angeleshaveproducedimprovedwaveforms(thetechnicalshape and cycles ofthe
electricalimpulses),increasedcontrols of risetime,duration of contractions, fall time, and rest time,
comfotable tolerance of higher intensity by improvingtypes of electrodes, and versatility inthe
designing ofa therapy program to meet the individual needs and select the specificmuscles of each
patient.
EMSis known by othernames. "Neuromuscular Stimulation"(NMS) isa termbecomingpopular in
somecircles ofthe UnitedStates. "Electronic Muscle Exercise" (EME) is widelyusedoutside ofthe
UnitedStates.Manyotherterms inEMSare fading from use because of mis-use or obsolescence,
such as "faradic" and "galvanic". They are still used, but primarily by manufacturers of devices for
the Europeanmarket, and someoldermodels ofEME deviceswhich arenot legallyallowed into the
UnitedStates for distribution.

PREPARATION FORUSE
1. Check Battery. Insurethat youare using a fresh battery.
2. Prepare Skin. Before applying electrodes, be sure to confirm
correct electrode placement as recommended by yourphysician
or therapist. Each locationshould be washed, rinsedand
thoroughly dried.
3. Prepare Electrodes. Apply gelina thin even layer (about the
thickness ofa match book cover) tothe bottom ofthe elec-
trode. Avoid using too much gel.
Note : Ifyouare usingreusableelectrode,
please disregard the procedure.

4. Attached Electrodes. Be surethat all sides are welltaped
and that the reusable electrodes is held firmly against the-skin.

INSTRUCTIONS FORUSE
6. Insert Pin into Electrode Socket. Insert pin connector into
electrode as shown.(Wheninserting or removing pin connector,
holdconnector-not cord-toprotect cord.) For some electrode
locations, itmaybe preferable to insert thepin connectorprior
to taping the electrode tothe skin.
7. Adjusting the Controls. Ensurethatamplitude controls for
both Channels 1 and2 are turned tothe "OFF"position.

CARE AND MAINTENANCE
IS. Portability.Your EMSis portable andmaybe clipped to;
belt, shirt pocket, braor other clothing.
16. Front Cover. A removablepanel covers the controls for
Contraction, Relaxation, and battery compartment. Your
medical professional may wish toset these controls foryouand
requestthat you leave the cover in place.

17. Battery. Dimming ofthe indicator lights signifies that the
battery should be replaced with a newoneas soon as possible.
However, the stimulator will continue to operate for several
morehours. To replacebattery,remove front cover(seeabove),
and extractbattery.Replace with 9 voltalkaline or similar
rechargable battery,takingcarethat the battey is insertedcor-
rectly. (Seediagram inside batterycompartment.)This EMS
unit is designed tobe used with batteriesonly, andcannotbe
operated from a line-poweredbatterycharger.
18. Care of Electrode Cords. Clean the electrodecords by
wiping with a dampcloth.Coatingthem lightly withtalcum
powder will reducetangling and prolong life.
APPLICATIONS
Relaxation of musclespasms: TheEMS unit can relax a "tense", "tight", or spasmodicmuscle.
Common candidates forEMS includethose in high stress situations who experiencemuscletension in
the upperback and neck areas, and those who suffer from chronic tensionheadaches.
• Increasingrange of motion: TheEMS unit is especially useful for those suffering from simple
arthritic symptoms or "stiffness" in joints,musclegroups, or backareas.
• Reduction or prevention of muscleatrophy: TheEMS unit will increasemotion,range, and response
of musclesrestrictedfromdususe or fromatrophyfromanothercause. Itis helpful following activity
restrictions, such as aftersurgery or bing ina cast.
• Re-enducation of muscles:Musclefiberslosetheir ability to contract if they arenot adequately
used. TheEMS unit repeats contractions of designatedmusclesre-educatingmusclefibers.This is
particularly beneficial to orthopedicpatientsrecoveringfrombeing ina cast ora splint, or bed-ridden
patients whoarenot able to maintaintheirmuscles(disuseatrophy).
• Increasinglocalblood circulation:(Self explanatory).
TheEMS unit canbe used inthe clinic orat home in comfort and privacy with completesafety
following the prescription and proper instructionfrom a physician/therapist.

SKIN CARE AND CONDUCTIVITY
For propermusclecontractiontheremust be conduction ofthe electricalimpulsesback and forth
between the electrodesthrough the tissue. The conductivity ofthe skin is important, as well asthe
amount of adipose tissuethatmust be penetrated. Obesityinhibitsconductivity,requires higher
amplitude levels for completecontraction.Certainchemicals,greasymaterials, and some metal
electrodes are poorconductors.Heat and light perspirationincrease conductivity. There are re-usable,
disposable,self-adhesive electrodes onthe market. The MS-100 typehypoallergenicreusable
electrodes are perhaps the best onthe market.They donot require theuseof straps.They canbe
moved from one position to another.They canbe trimmed toany size or shape to conform to small
muscles. Becausetheyprobably arethe most scientifically advanced onthe market,distributors ofthe
EMS unit alsodistribute .the MS-100 EMS electrodes.They canbe re-usedabout25-35times if
handled gently.Reminders:Returnamplitudeknobs(#4) to"0" beforechangingplacement ofthe
electrodes. Be sureelectrodes fit snugly duringstimulation to avoidtinglingdiscomfortscaused by
loose contactbetweenelectrode and skin.Also,cramps are commonwhenexercisingmusclesweak
from disuse.Restingthenre-usingmoderate EMS repeatedly for 5-15 minutes usually eliminates the
cramps.

NOTES
•Youmay placebothpairs of electrodes overvariousmusclegroups atone time.
•Itis best to place thetwo electrodes ofa singleoutletlead onthe sameside ofthe body.
• Even during highamplitudelevels of contraction,mostpersons can sleep or restonce theyhave
becomeaccustomed to EMS.
• Each pair of electrodes maybesetata differentlevel of intensity. Different musclesrequire
varying degrees ofEMSto reach a full contraction.
•Itis important to understandthat theoff time,when the musclesrestbetweencontractions, is
critical. Sufficient timebetweencontractions in order forthe muscles to relaxtotallyreduces the
possibility of muscle fatigue.After a modestamount ofuseof EMS, an individual does adjust tothe
contractions so wellthatless and lesstime is necessary for the muscle to relax.
•Asinany exercise, EMS exercise may causesoreness in muscles. If thisoccurs,resting the
muscle,even foruptoa dayor two,shouldeliminate the soreness. Asthe personbecomes
accustomed tothe exercise, sorenessshould no longer occur. Should it reoccur, the physician or
therapistshouldevaluate the program and factors ofuseto ascertaincorrectivemeasures.

PRECAUTIONS
TROUBLESHOOTING
DonotuseEMS whileoperatingpowerequipment or machinery, or while driving an auto.
Physicians should use caution in recommending EMS duringpregnancy; its safetyduringpregnancy
hasnot beenconclusivelydetermined.
1 Effectiveness is dependentuponpatientselection.
CONTRAINDICATIONS
EMS should notbe prescribed for personsusingdemand-typecardialpacemakers, or with patients
known to havemyocardial diseases or arrhythmias or with cardiac patients in general.
EMS electrodes should notbe placedover the carotidglands, or over the pharyngeal or laryngeal
muscles.
EMS electrodes should notbe placedoverhealingfractures in such a manner as possibly to cause
stress inthe fracturearea.
1 Any electrode placement that causes current to flow transcerebrally (through the
head) isnot allowed.
If your EMS unit does not seem tobe operatingcorrectly,refer tothe chartbelow to determinewhat
may be wrong.Shouldnone of thesemeasurescorrect the problem, the unit will needservicing.
