Surface electromyography instructions for use (sEMG)

In the I-TECH PHYSIO EMG version, the device is equipped with a
biofeedback module
electromyographic signals (sEMG). It's designed to detect signals
generated by the human body and gives feedback from two channels. The
bioelectrics signals are detected in single differential modality with bipolar
electrodes.
These signals are amplified, filtered, and converted to digital. The device
doesn't show an electromyographic signal, but a contraction (bar) signal
also indicated in µV, like differential value between refer electrode and
bipolar electrode: in this respect, the indicated value is simply a reference
that must not be considered like a value with diagnostic purpose (doesn't
provide information nearly the muscle condition or the presence of
pathologies ) but only serves to physiotherapist/doctors to set up an active
muscle session/training for the patient. The EMG module should not be
intended as a medical device with diagnostic purpose.
The biofeedback is both visible (display) and both acoustic (internal
buzzer).
With I-TECH PHYSIO EMG is possible recorder different levels of maximum
voluntary contraction of two muscles and so set up different thresholds of
feedback for each muscle and execute a controlled work calibrating the
training degree.
ATTENTION! It's recommended not to use the electromyography
(EMG) mode with the power supply connected to the domestic
electricity network (device charging) since it's not possible to
filter out the impurities of the external network.
To access to the functionality of the EMG module, simply click on the EMG
icon in the I-TECH PHYSIO EMG main menu: the channel setup menu will be
displayed with a screen similar to the one in the figure below.
The operating menù of the 4/EMG module is as follow:
