Effect of spinal cord electrostimulation on human vertical stability

Vertical stability training and postural control improvement are important tasks of physical rehabilitation, occupational physiology and sport physiology. The objective of the research is to study the effect of a single-shot transcutaneous electrical stimulation of the cervical spinal cord thickening on human vertical stability. Materials and Methods. The study involved 14 adult healthy male subjects aged 18-26. The trial subjects underwent a single-shot transcutaneous electrical stimulation of the spinal cord at the C3-C4 cervical vertebra level, pulse-recurrence rate was 1, 5, 15, 30 and 50 Hz, the procedure lasted 3 and 10 min. The authors evaluated vertical stability of the trial subjects while they were performing various motor tasks before and after the electrical stimulation. Biofeedback computer stabiloanalyzer was used to complete the task. Results. Percutaneous electrical stimulation of the cervical spinal cord thickening led to a statistically significant change in stabilographic parameters, which reflect an increase in postural control...
