[Changes in the excitability of the spinal motor neurons during sessions of functional biocontrol in patients with different forms of infantile cerebral palsy].
Excitability changes at the segmentary level of the spine were examined during functional bioregulation sessions administered to patients with various forms of infantile cerebral paralysis (spastic diplegia, spastic hemiparesis) by recording N- and M-responses of musculus soleus and musculus gastrocnemius medial head. Neurophysiologic disorders were revealed at the spinal level depending on the disease form. The authors suppose that presynaptic inhibition is to a greater measure impaired in spastic hemiparesis, whereas spastic diplegia is associated with more extensive involvement even of spinal inhibitory mechanisms proper. Sessions of functional bioregulation resulted in clinical improvement and in development of a trend to normalization of spinal reflectory excitability. Such changes were recorded in musculus soleus of children with spastic diplegia and in gastrocnemius muscle median head of those with spastic hemiparesis. Possible effects of directed afferent currents on structure and function of supraspinal systems regulating spinal mechanisms activity are discussed.
