Description

The computer elektromiograf of M-TEST allows to register the electromyogram on 1, 2 or 4 channels according to the chosen EMG-research technique. At the same time the order and a set of the used techniques at inspection of the patient is defined by the doctor randomly, according to pathology.

The high technical characteristics of the device and special software realized in system allow to receive a high-fidelity recording of the electromyogram in any room. During registration and viewing of the electromyogram it is possible to change amplitude and temporary development and to print the written-down EMG.
The system is designed so that the researcher had an opportunity to quickly obtain necessary information for viewing and the analysis. Results of the analysis can be presented in the form of tables, schedules and charts that considerably facilitates perception of information. The simple and convenient interface of the program, evident submission of the contents and results of EMG-inspection, the automatic description, existence of base of medical norms, a possibility of their editing - all this is aimed at providing effective work of the researcher.

Technique of superficial EMG

Registration of spontaneous activity of muscles the superficial taking-away electrodes with adjustable or stationary intercenter distance between slip rings.

In system key parameters of interferential EMG are defined:

  • frequency of total electric activity of muscles;
  • maximum amplitude of a signal;
  • average amplitude of a signal.







Technique of stimulation EMG

Registration of the caused answers of a muscle as a result of electric stimulation of a peripheral nerve. The analysis of characteristics of the M-answer provides definition of a threshold of generation, the latent period, amplitude, duration and area, calculation of an indicator of residual latency and speed of carrying out an impulse on motive fibers in the M-TEST system, definition of dynamics of indicators. For a conductivity assessment on sensitive nervous fibers research of potential of action of a nerve with calculation of speed of carrying out excitement for sensitive fibers is provided. Research of late responses to stimulation includes the analysis of characteristics of a F-wave (latency, motor speed of carrying out, a hronodispersiya, a takheodispersiya, average speed, amplitude, a ratio of the size F-and M-answers) and the analysis of parameters of a H-reflex (latency, amplitude, a threshold of generation of a H-reflex, a ratio of dynamics of the N-reflex with dynamics of the M-answer).
