Purpose

The user is able to use one, two or four standard leads in the real time. The device can be efficiently used as in stationary conditions, as well as in the field (it doesn't require 220V power socket). The manufacturer implemented a wide set of innovative solutions in order to provide the highest quality of the electromyogram (EMG) with the lowest levels of both noise and interference.

Synapsis Electromyograph allows carrying the following procedures out:

analysis of the interferometric, spontaneous and integral EMG
turn amplitude and spectral analysis
event-related potential analysis
calculation of the impulse conduction in the motor (proximal and distal zones) and afferent nerves
definition of the F-wave characteristic
analysis of H-reflex and opticofacial reflex
M-response decrement analysis in order to define the rhythmic stimulation and tetanization
reciprocity analysis

The system supports various dental methods in order to evaluate the state of masticatory and mimic muscles, as well as all modalities of the event-related potentials.

This configuration is supplied with a set of accessories allowing carrying out the following procedures:

visual event-related potentials as a result of light flash and reciprocal check pattern
acoustic event-related potentials with long and short latency
somatosensory event-related potentials
cognitive event-related potentials

The system supports various dental methods in order to evaluate the state of masticatory and mimic muscles.
