The effects of spinal cord rhythmic electric stimulation on the coordination structure of a running step

The article presents the results of the studies with the use of percussive electrical stimulation of the coccygeal plexus contrasted with the runner’s cyclic action on the treadbahn. The research involved 8 healthy men of 17-25 aged. The test subjects ran at maximum speed on a treadmill (Cosmos Venus, Germany), which was in passive mode, i.e. pushing the tape of the tracks with their feet, holding onto a transverse handrail. Each subject performed a running exercise for 10 seconds without electrical stimulation and then for 10 seconds under coccygeal plexus continuous electrical stimulation. The obtained experimental data showed that using coccygeal plexus rhythmic stimulation as the runner cyclic actions background, leads to legs antropometrical points velocity increasing during fly phase and investigated lower extremities muscles EMG activity rising.
