Surface EMG
The main parameters of surface interference EMG include the frequency characteristics of muscle electrical activity, maximum signal amplitude, and average signal amplitude. In orthopedic dentistry, additional analysis of chewing tests is performed. In pain research, the assessment of voluntary muscle activity is commonly used.
Stimulation EMG
The use of current stimulation ensures high accuracy in the assessment of nerve conduction. Muscle responses or electrical activity are recorded using current stimuli of precisely controlled duration and amplitude. Early responses (M-response) or late responses (F-wave, blink reflex, H-reflex) allow for the determination of the level and localization of lesions in the peripheral neuromotor system. Sensory and motor fibers can be assessed separately by measuring sensory and motor conduction velocities. Therefore, this group includes the basic methods applied in the differential diagnosis of neuromuscular disorders.
A specific type of stimulation response assessment involves rhythmic stimulation. The decrement test is performed to evaluate the reliability of neuromuscular transmission. Tetanic stimulation and pharmacological loading tests can be used to identify myasthenia gravis and Lambert-Eaton myasthenic syndrome.
Needle EMG
Needle electromyography (local EMG) assesses the functional state of muscles at rest and under voluntary load. Needle EMG are particularly informative in primary muscle diseases and differ from those observed in nervous system disorders. Based on the results of a comprehensive ENMG study, the level of peripheral neuromotor system involvement, as well as the nature, severity, and extent of the pathological process can be determined; repeated examinations also allow for the assessment of treatment effectiveness.
Methods for 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 detect even hidden disorders at early stages. These types of EPs may be sensitive to dysfunctions that cannot be identified through physical examinations or MRI alone.
Somatosensory evoked potentials are often used in neuromonitoring to assess spinal cord function during surgery.
Galvanic skin response serves as an indicator of autonomic nervous system activity.
The “M-TEST” software enables convenient work with databases. In addition to all patient information, recorded electromyograms, and their processed results, it provides a full set of tools for efficient management of electronic patient records and large-volume data 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 clinical inerpretation and report conclusions.
The software also supports exporting and importing all electromyographic examination data, enabling further information exchange with other specialists for clinical practice or scientific research.
