INSTRUCTIONS FOR USE
We strongly recommend that you carefully read the contraindications and safety measures described in the "Intended Use" chapter of this
manual.
Preliminary checks
•
Make sure the stimulator battery is fully charged before each use session.
•
Make sure that at least 2 electrodes are available to stimulate the muscles of interest.
•
Check that the environmental and safety requirements described above are met.
Positioning of the electrodes
It is important to use the electrodes provided in the kit and to position
them correctly on the muscle group you wish to stimulate in order to
ensure the effectiveness of the treatment. Always follow the
positioning instructions shown in the following figures, except in the
case of specific medical indications.
Remark: an approximate positioning of the electrodes makes the
session less effective, but it does not constitute a danger, except for
the contraindications described in this manual.
The electrode is positioned in the area of the nerve supplying the
hypoactive muscles. Simultaneous stimulation of agonist and
antagonist should be avoided because of the resulting movement
restriction. One electrode is placed inferior to the spina scapulae to
stimulate the external rotators (M. infraspinatus, M. teres minor). The
second electrode is placed medially to the margo medialis scapulae to
stimulate the scapula retractors (M. trapezius pars transversa, Mm.
rhomboidei).
Positioning of the stimulator
Place a layer of skin protection in the area of the arm that will be in contact with the stimulation device. Ensure that the protective layer covers
the skin and avoids direct contact between it and the stimulation device. The stimulator is posteriorly equipped with an elastic band to be
positioned around the right or left arm based on the side of the pathology to be rehabilitated. Make sure Velcro fixing is stable on the arm. The
device must be properly positioned in order to guarantee the correct connection of the cables to the electrodes. To check correct positioning,
connect the conductor cables to the electrodes taking care to keep the device switched off. Try to raise the arm frontally and laterally and
check that cables are not stressed and movements are comfortable for the subject.
Setting of stimulation energies
In a stimulated muscle, the number of fibers involved depends on the stimulation energy. For programs that induce powerful muscular
contractions (tetanic contractions) it is absolutely necessary to use the maximum stimulation energies, within the subject’s tolerance limits, in
order to involve the greatest possible number of fibers. For other types of programs, which only induce muscle contraction, the stimulation
energies must be progressively increased to obtain clearly visible muscle twitches.
It is important to use the maximum current intensity that the patient can comfortably tolerate, which generally increases during the course of
the treatment, In general, it is not advisable to exceed the levels too quickly: the different levels correspond to a progressive advancement in
training through electrostimulation.
WARNING
: Use this device only with cables, electrodes and accessories recommended by NCS Lab.
