Surface EMG
Main parameters of interference EMG: frequency of total muscle electrical activity, maximum signal amplitude, average signal amplitude. For orthopedic dentistry, an additional analysis of the chewing test is provided. In pain studies, the investigation of voluntary muscle activity is used.
Stimulation EMG
The use of current stimulation ensures high accuracy in the study of nerve conduction. Muscle response or electrical activity is measured using a current stimulus of precise duration and amplitude. Early responses (M-response) or late responses (F-wave, blink reflex, H-reflex) allow determining the level and localization of peripheral neuromotor system lesions. Sensory and motor fibers can be assessed separately by measuring sensory and motor conduction velocity. Therefore, it is fair to note that this group includes basic methods applied in the differential analysis of neuromuscular diseases.
A special type of response analysis to stimulation is analysis using rhythmic stimulation. The decrement test is performed to evaluate the reliability of neuromuscular transmission. The tetanic contraction test and pharmacological loading can be used to detect myasthenia and Lambert-Eaton myasthenic syndrome.
Needle EMG
Needle electromyography (local EMG) studies the functional state of muscles at rest and under voluntary load. The results of needle EMG may be useful in primary muscle diseases, which differ from those observed in nervous system disorders. Based on the results of a comprehensive ENMG study, the level of peripheral neuromotor system damage, the nature, degree, and extent of the pathological process are determined, and in repeated studies – the effectiveness of therapy.
Methods of recording evoked potentials differ significantly from other studies conducted within EMG.
They address specific tasks. Visual evoked potentials can be used to confirm damage to the visual tract, while auditory evoked potentials are used to assess hearing and the function of nerve pathways from the ear to the brain, helping to detect even hidden disorders at early stages. These types of EPs can be sensitive to dysfunctions that cannot be detected solely through physical examinations or MRI.
Somatosensory evoked potentials are often used in neuromonitoring to assess spinal cord function during surgery.
Galvanic skin response is an indicator of autonomic nervous system activity.
The M-TEST ONE software allows convenient work with databases – in addition to all patient information, recorded electromyograms, and their processed results, it provides a full set of functions for comfortable work with electronic patient files and large-volume information archives.
To optimize the preparation of medical documentation, report generation is highly automated. Examination results can be printed, saved in digital format, or transmitted via email or local network.
Mathematical and statistical processing of electromyograms is automatically presented in a format suitable for forming a conclusion.
The software provides functions for exporting and importing all electromyographic examination data with the possibility of further information exchange with other specialists for practical use or scientific research.
