[Recurrent inhibition in patients with lesions of the central nervous system]. / Vozvratnoe tormozhenie u bol'nykh s porazheniem tsentral'noi nervnoi sistemy.

Recurrent inhibition was studied by antidromic stimulation of Renshaw's cells. 25 normal subjects and 74 patients with CNS lesions accompanied by movement disturbances were examined. During weak voluntary contraction of the soleus muscle, the stimuli were applied to motor fibers of the n. tibialis (weak M-response was evoked). In normal subjects, the stimulation was followed by short-latency suppression of the EMG background activity of the muscle brought about by recurrent inhibition. The same inhibition was revealed in patients with spastic paresis caused by pyramidal system lesion. However, the stimulation failed to evoke the recurrent inhibition in patients with movement disturbances caused by brain stem and cerebellum lesions, including patients with hypotonia.

[Effect of the position of the body in space on the dynamics of tendon reflexes in stroke patients during the rehabilitation period]. / Vliianie polozheniia tela v prostranstve na dinamiku sukhozhil'nykh refleksov u bol'nykh v vosstanovitel'nom periode mozgovogo insul'ta.

Chronometry of Achilles reflexes in 40 healthy subjects and 25 patients in the recovery period after cerebral stroke with regard to body posture showed that in normal subjects the vertical position was associated with a reduced time of the reflectory response whereas in the patients it was increased. It is assumed that a change in the speed of tendon reflexes in different postures is related to the readjustment of suprasegmental and afferent influences on the segmental apparatus of the spinal cord.

[Changes in the postural equilibrium of patients with cerebral circulatory disorders]. / Izmeneniia postural'nogo ravnovesiia u bol'nykh s narusheniem mozgovogo krovoobrashcheniia.

The results of a study on the postural balance in 80 patients with cerebral circulation disorders are presented. Statographic disorders were found to be dependent on the nature, severity and localization of the pathologic process.
