6 Intended use Vacuum
The continuous and pulsed vacuum module allows vacuum electrodes to be positioned quickly
and easily. Furthermore, it is extremely simple to switch between treatment with vacuum
electrodes and treatment with flexible rubber electrodes. This makes the vacuum module an
ideal aid for electrode placement.
Vacuum electrodes make good contact with the skin, which means that effective use is made of
the whole electrodes area. The massage effect resulting from the pulsed vacuum ensures a
good blood through the skin under the electrodes. This reduces the resistance of the skin and
increases he effectiveness of the stimulation current.
7 Intended use Myofeedback
Myofeedback is a form of feedback, in which the patient receives electronically recorded
information about his own physiological processes. The electromyographic recording used in
the diagnostics and treatment of the moving mechanism is an indispensable supplement to the
study of movement. When we place electrodes on the skin to obtain information from an EMG
signal about the underlying musculature, we must be acquainted with the development of the
EMG signal and the construction and function of the motor mechanism. Thus, properties and
mutations in the musculature, the joints system, the sensory and the neural system can be
found in the motor system and also in the EMG recording.
Surface EMG provides us with detailed information about the organ-specific properties of a
muscle, such as:
•
the activation of the muscle;
•
the muscle’s capacity f or relaxation;
•
coordination between muscles;
•
the tiredness of a muscle;
•
the capacity of a muscle to lengthen.
This makes Myofeedback especially suitable as a measuring instrument for charting our
locomotive operations (Figure 1).
7.1 Parameters
Sensitivity, allows changing the sensitivity from the measurement range. For surface EMG the
read-out is in µV and the pressure read-out is in hPa.
Shift, this parameter makes it possible to zoom-in on a specific area in the graphic to have a
better feedback for the patient.
Threshold can be used as target function in feedback therapy. In combination with electro
stimulation the threshold triggers the start, or end of the stimulation.
Graph, here you can select the graphical feedback on the screen. There are 2 feedback
possibilities, by bar or curve. The colours are not changeable.
Sound, is the acoustic feedback during the treatment. Several settings are possible.
Record, this parameter need to be use as start en registration of the treatment.
Analyze, at the end of the treatment time or after the use of the Stop you can analyze the whole
session. Select the icon

in the analysis menu to move the cursor in the curve. The value
from that position will be displayed on the screen. To zoom-in on that area you can use the loop
icon.
Report, here you can find the result of the last session in figures.
Cycles, h ere you can set the repetitions of the training. This parameter is only applicable in
Myofeedback mode; Excerice/ Rest and Template and the Myofe Stimulation mode.
Template, select here the curve type. There are six different training curves available .
