1. GENERAL DESCRIPTION What is BIO EMG: this is a biofeedback instrument based on the analysis of surface electromyographic signals (sEMG). The device is designed to detect signals generated by muscles in the human body and provide feedback from two channels.

example, you want muscle activation to be maintained below a certain threshold (the patient is alerted each time the threshold is exceeded, being aware of this and focusing on muscle Under threshold relaxation). See how to use the working mode on page 17. When to use the Maintain Target mode This mode guides the patient to perform contractions until reaching a Target which must be maintained for a variable period of time (2-5 seconds).
(sEMG) received by electrodes placed on the skin. The device is suitable for training and recovery of muscles after injury; it is useful for quantitative and qualitative definition of muscular activity. To use the BIO EMG device properly you must read the user manual. I.A.C.E.R. S.r.l.
Immediately contact the manufacturer if foreign materials get inside the device (liquid, powder, etc.). Should BIO EMG be subjected to impacts (like a fall to the ground, etc.), make sure that any crack or any other type of damage of the casing has damaged the device.
• The use of BIO EMG is allowed to persons properly trained on how to use the same by reading the user manual. 5. MEANING OF THE SYMBOLS ON THE BIO EMG AND IN THE USER MANUAL The four front keys allow the user to completely control the device and all its functions.
