title: [Changes in the motor units of the muscles in patients with residual symptoms of poliomyelitis].
abstract: Based on an analysis of potentials of motor units (MU) of the skeletal muscles of patients with the postpoliomyelitis syndrome (PPMS), tick-borne encephalitis and spinal amyotrophy, a conclusion is made about the common trend of changes in MU in the given diseases. The degree of changes in MU depends on the grade of physical and trophic load of the preserved nerve elements. As the reserve possibilities of motoneurons are depleted, the process gets aggravated, with the formation of compensatory innervation insufficiency and the rise of muscle atrophy. In patients with PPMS, the decompensation of the pathological process starts, as a rule, at the definite age period and depends on the intensity of the primary defect formation.
