MediStim XP IM W Europe_PolyStim XP GA 290905.qxd 01/12/2010 12:49 Page 5

Intended Use:
MediStim XP applies muscle and nerve stimulation using the principles of Neuromuscular Electrical Nerve Stimulation (NMES)
which are defined below. The unit sends short electrical impulses through the surface of the skin via adhesive electrodes.
Neuromuscular Electrical Stimulation (NMES):
NMES may be defined as the application of electrical stimulation of the peripheral nervous system to contract a muscle either
through the direct activation of the motor neurons in the mixed peripheral nerve, or indirectly through reflex recruitment.
Transcutaneous Electrical Nerve Stimulation (TENS)
TENS is a pain therapy based on the application of electrical stimuli to the skin via stimulation of the nerve fibers. There are two
methods: The “pain gate” theory, which blocks the pain signals to the brain, and/or through the increased release of endorphins,
which inhibits the emergence of pain.
Indications:
• Detones muscle spasticity.
• Prevention or retardation of disuse muscle atrophy.
• The symptomatic relief and management of acute pain.
2.0 Contra-Indications
• Patients with electronic implants (e.g., pacemakers and defibrillators) may not use the unit!
2.1 Precautions & Warnings
• If in doubt, always seek medical advice.
• Caution is recommended in patients diagnosed with heart problems or suspected heart problems.
• Medical advice must be obtained before use on persons who are insulin-dependent diabetics or for persons who are under medical
supervision for any cognitive dysfunction.
• Medical opinion must be obtained before persons with any serious illness or injury apply muscle stimulation.
• Safety has not been established for the use of muscle stimulation by pregnant women, persons with cancer or epileptics.
• Do not apply stimulation in the region of recent surgery without medical approval.
•
Avoid applying over recent scars or on broken or inflamed skin, areas of infection, areas susceptible to acne, thrombosis or other
vascular problems (e.g. broken veins or varicose veins).
• Avoid placing the electrodes directly over metal implants if there is not at least 1 cm of muscle fibre in between. However placement
on the nearest muscle is possible. If in doubt, seek medical advice.

SAFETY INFORMATION
• Precautions should also be taken if muscle stimulation occurs during heavy menstruation or in the same month as the insertion of
an IUP (inter-uterine pessary, e.g. coil). The same applies to the period (6 weeks) after giving birth. We recommend that stimulation
is only applied around the abdominal or lower abdominal region following medical approval.
• Medical advice must be obtained before applying stimulation on recent fractures or to parts of the body where feeling is limited.
•
In all cases, ensure that stimulation does not exceed the patient’s tolerance level.
• When repositioning electrodes during treatment, always turn the intensity to minimum or pause the unit.
• Lead pins and electrodes must not be connected to other objects.
• When the cables are attached to the electrodes, ensure that the lead pins are fully inserted into the electrode sockets. Ensure
that no metal is visible.
• The device should be kept safely out of the reach of children.
•Simultaneous connection of a patient to high frequency surgical equipment may result in burns at the site of the stimulator
electrodes, and possible damage to the stimulator.
• Operation in close proximity to shortwave or microwave therapy equipment may produce instability in the stimulator output.
• Electronic monitoring equipment (such as ECG monitors and ECG alarms) may not operate properly when the stimulator is in use.
• It may not be appropriate to use MediStim XP on a person at the same time as other equipment. You should check suitability
before use.
• The MediStim XPunit should be used only for its intended purpose and in the manner described in this manual. You should also
use only those electrode positions indicated by your clinician.
• A small number of isolated skin reactions have been reported, including allergies and acne.
• Stimulation should not be applied until the cause of the pain is identified and a precise diagnosis rendered.
• To avoid infection electrodes may only be used by a single individual.
• TENS is not intended to treat psychosomatic illness.
• TENS primarily treats symptoms by suppressing pain, which in turn serves as a protective mechanism.
•
This device can deliver current densities in excess of 2mA/cm2when used at a high intensity with small electrodes. See “Technical
Information” for more details.
• The long-term effects of continuous electrical stimulation have not been investigated.
If any irritations, skin reactions, over-sensitivity or other side effects occur, please contact BMR Ltd In such cases stop use immediately.
Irritations can usually be reduced by changing the position of the electrodes. Note, however, that a slight reddening of the skin is
quite normal under the electrodes during and for a short time after treatment.
English
MediStim XP IM W Europe_PolyStim XP GA 290905.qxd 01/12/2010 12:49 Page 7

Please do not use the MediStim XP unit in the following way:
• Stimulation must never be applied transcerebrally (across or through the head), directly on the eyes, covering the mouth,
transthoracicly (electrodes placed on the chest and the upper back or crossing over the heart - as such an application of electrical
current into the heart may cause arrhythmia), or on the front of the neck (especially the carotid sinus nerves).
• Do
not use the MediStim XPunit with the electrodes positioned on injection sites (of medications/ drugs), such as hormone
treatment sites.
• Do not use while driving or operating machinery.
• MediStim XPmust not be used with any other unit that delivers electrical current to the body (e.g. interferential or another muscle
stimulator).

Note 3: For this program, when the amplitude is at maximum, the value written to the R2R resistor network is less than half the
maximum of 255.
The Trigger mode ( ) is possible in Programs 1 – 5, 8 and 9. When the button is pressed the trigger mode is activated and the unit
enters a contraction cycle for as long as the key is pressed. When the key is released the unit enters the relaxation cycle. To return
to the programmed contraction/ relaxation cycle, press any of the intensity keys. The stimulation builds over a 2 second period to
the previously set intensity level.

Utilisation
Le MediStim XPpermet une stimulation musculaire et nerveuse selon les principes de l’électrostimulation neuromusculaire (ESNM) et
de la stimulation nerveuse électrique transcutanée (SNET). Il s’agit de courtes impulsions électriques délivrées par l’intermédiaire
d’électrodes placées à la surface de la peau.
Électrostimulation neuromusculaire (ESNM)
L’ESNM peut être définie comme une stimulation électriq u e d u syst ème nerveux périphérique dans laq u e l l e les musc l es so nt stimul é s
soit par l’activation directe des motoneurones dans le nerf périphérique mixte, soit indirectement par des réflexes renforcés.
Stimulation nerveuse électrique transcutanée (SNET)
La SNET est un traitement contre la douleur qui se fonde sur l’application d’une stimulation électrique sur la peau avec stimulation
des fibres nerveuses. La SNET peut être pratiquée de deux manières : soit selon la théorie « pain gate », qui a pour effet de bloquer les
impulsions de douleur envoyées au cerveau, soit par la libération accrue d’endorphines, qui inhibent les phénomènes douloureux.
Indications
• Soulagement en cas de myoplastie
• Prophylaxie ou inhibition de l’atrophie musculaire par inactivité
• Amélioration des symptômes et traitement des douleurs chroniques et aiguës
2.0 Contre-indications
• Les patients avec des implants électroniques (par exemple pacemaker et défibrilateurs) ne doivent pas utiliser l’appareil !
2.1 Mesures de précaution et mises en garde
• Prenez systématiquement l’avis du médecin si vous avez les moindres doutes.
• La prudence s’impose pour les patients chez lesquels des problèmes cardiaques ont été diagnostiqués ou sont probables.
• Le conseil du médecin est également indispensable aux patients souffrant de diabète insulinodépendant ou qui sont sous surveillance
en raison d’autres perturbations des fonctions cognitives.
• Les personnes souffrant d’une maladie sévère ou de blessures graves doivent elles aussi consulter un médecin avant toute
stimulation musculaire.
• Pendant la grossesse, dans les cas de cancer ou d’épilepsie, la stimulation musculaire ne présente pas un degré de sécurité suffisant.
• N’appliquez pas sans prendre un avis médical la stimulation à des parties du corps qui ont été récemment soumises à une opération.
• Evitez l’application sur un tissu cicatriciel frais ou sur des plaies ouvertes ou enflammées, tout comme à des endroits infectés par
l’acné ou propices à l’acné, en cas de thrombose ou de toute autre pathologie vasculaire (par exemple veines éclatées ou varices).
• Evitez de placer les électrodes directement au-dessus d’implants métalliques, si ceux-ci ne sont pas au minimum recouverts par 1 cm
de masse musculaire. Il est cependant possible de poser l’électrode sur le muscle le plus proche. En cas de doute, adressez-vous
à un médecin.
• Un avis médical doit également être pris lorsque la stimulation doit être effectuée sur des parties du corps à sensibilité réduite
ou à des emplacements présentant des fractures osseuses récentes.
