CLINICAL AND NEUROPHYSIOLOGICAL FEATURES OF ELECTRONEUROMYOGRAPHIC SAMPLES IN PLEXOPATHIES OF COMPRESSIVE AND INFLAMMATORY ORIGIN

Relevance. Brachial and lumbosacral plexopathies are among the most difficult diagnostic groups among peripheral nervous system diseases. Due to the similarity of clinical signs, it is difficult to differentiate plexopathies of compression and inflammatory (immunomediatory) origin, and electroneuromyography (ENMG) remains the primary objective method in this regard.
Goal. Comparative analysis of the clinical and neurophysiological features of ENMG samples in plexopathies of compression and inflammatory origin and justification of the diagnostic algorithm.
Materials and methods. Analysis was conducted based on literature data and the standard ENMG protocol (sensory and motor nerve conduction, F-wave, needle electromyography).
Results. In compression plexopathies, focal demyelination and conduction block predominate, while in inflammatory plexopathies, axonal lesions, multifocal, and asymmetrical changes predominate. A decrease in the amplitude of the sensory nerve-motor potential (SNMP) is the primary sign of postganglionic damage.
Conclusion. Clinical-neurophysiological comparative assessment is important for determining the etiology of plexopathies, choosing treatment tactics, and prognosis.
