title: [Biomechanical and neurophysiological characteristics of voluntary rhythmic movements in humans].
abstract: Amplitude modulation of electroencephalogram and H-reflex were studied under realization and completion of voluntary rhythmic movements and its modelling by means by electrical stimulation of the triceps sure muscles in humans. The changes of spinal cord alpha-motoneurons excitability was correlated with the cycle duration under rhythmic voluntary movements realization and not depend on cycle duration under its semantic completion. The alpha-motoneurons excitability was stable and did not determine by model movement frequency in condition of rhythmic electrical stimulation and after its stopping. Analysis amplitude modulation of electroencephalogram and H-reflex under voluntary rhythmic movements showed correlation between cortical and spinal processes under its organization.
