Anatomical, physiological, and functional connectivity exists between primary motor cortex (M1) and spinal cord neurons. Paired associative stimulation (PAS) produces enduring changes in M1 based on the Hebbian principle of associative plasticity. The present study aims to discover immediate neurophysiological changes on human corticomotor pathways by pairing noninvasive transspinal and transcortical stimulation via transcranial magnetic stimulation (TMS). We delivered paired transspinal and transcortical stimulation for 40-min at precise interstimulus intervals with TMS being delivered after (transspinal-transcortical PAS) or before (transcortical-transspinal PAS) transspinal stimulation. Transspinal-transcortical PAS markedly decreased intracortical inhibition, increased intracortical facilitation and M1 excitability with concomitant decreases of motor …

The Effects Of Plyometric Training On Spinal And Supraspinal Motor Control, Jeffrey R. Doeringer

Internet Journal of Allied Health Sciences and Practice

Purpose: The purpose of this study was to determine the effects of plyometric training on spinal and supraspinal motor control in healthy active females. Methods: A 2 (Group) x 2 (Session) x 2 (Stance) mixed model design was used for homosynaptic depression (HD) and recurrent inhibition (RI) data. A 2 (Group) x 2 (Session) mixed model design was used for H:M ratios and V-waves (V:M ratios) data. Thirty-one participants were recruited to participate in the study. Participants participated in either the training or control group for 6-weeks. All participants were measured pre- and post-intervention on H:M ratios, HD, RI, …
