ELECTRONEUROMYOGRAPHIC (ENMG) CHANGES IN CONGENITAL MYOPATHIES AND THEIR ROLE IN DIAGNOSIS
Keywords:
Congenital myopathy; ENMG; Muscle activity; Nerve conduction.Abstract
This study aims to assess the diagnostic value of electroneuromyographic (ENMG) changes in congenital myopathies. ENMG studies allow us to study the functional state of muscles and peripheral nerves by determining their electrical activity. The results of the study showed that congenital myopathies are characterized by low amplitude of muscle potentials, short-duration motor unit potentials, and normal nerve conduction. These features allow using ENMG as an effective method for early detection of congenital myopathies and their differentiation from neuropathies.
