6.1 How to use the Motor Point Pen
The Motor Point Pen supports in locating the optimal electrode position for the mucle stimulation (e.g.:
locating the motor point of the vastus medialis of the quadriceps).
Background:
Muscular electrostimulation programmes are programmes which subject the muscles to work. The
progress achieved depends on the kind of work to which the muscles are subjected, that is to say the
programme chosen. The electrical pulses generated by these programmes are transmitted to the muscles
(via the motor nerve) through self-adhesive electrodes. The positioning of the electrodes is one of the
determining factors in ensuring a comfortable electrostimulation session.
It is therefore essential to devote special care to this aspect. The correct placement of the electrodes and
the use of significant energy allow a large number of muscle fibres to work. The greater the energy, the
greater the spatial recruitment, that is to say the number of fibres working, and therefore the greater the
number of fibres that make progress.
The motor point:
The motor point is a point where the motor nerve enters the muscle, which is an extremely localised
area where the motor nerve is at its most excitable. Although the location of the various motor points
is now well known, there may nevertheless be variations of up to several centimetres between dierent
individuals.
The Motor Point Pen, combined with the motor point program, allows determining with greater accuracy
the exact location of the motor points for each individual and thus ensuring the greatest eectiveness
of the programmes. It is recommended to use this programme and the pen before any initial muscular
electrostimulation session. Once located, the motor points can be easily identified by using a skin-marker
pencil or in any other way, thus avoiding the need to repeat this process before each session.
Electrode placement:
One stimulation channel is a module consisting of two pods:
A positive pole (+) = the pod with an illuminated button
A negative pole (-) = the other pod of the module
The positive electrode is the one connected to the positive pod (with an illuminated button). It is supposed
to be attached at the motor point of the muscle.
Note
The Motor Point Pen is designated only to be used in combination with the program “Motor Point”.
