This is a cost-efficient model based on the standard Synapsis configuration. It can be used to carry the standard electromyographic procedures out, which require only one or two simultaneously working channels for EMG. Such procedures include needle, stimulation and the majority of epicutaneous examinations.

The user is able to use one or two 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


Software features

  1. Database to store information about the patients and examinations
  2. Software complex to control all the parameters of the monitored signals and stimulating actions.
  3. Automatic and automated detection of the required segments of the electromyogram.
  4. Digital signal processing algorithms for classification, calculation, and graphical representation.
  5. Ability to create reports.
