“…Devanne et al (2002) have shown that extensor carpi radialis (ECR) muscle MEPs are facilitated when this muscle is co-activated with the anterior deltoid. We observed that both the size of the cortical representation and the excitability of the brachioradialis muscle are enhanced during co-activation of a proximal muscle (Tyč & Boyadjian 2011). Notably, MEP facilitation was not observed in finger muscles during co-activation of proximal muscles (Devanne et al 2002, Dominici et al 2005.…”

“…In such conditions, centers of gravity of typically remote muscles can become proximate owing to their co-contractions. These co-contractions serve as adaptations for weak muscles [69]. Future studies can employ longitudinal designs of strengthening, or compare stronger versus weaker adults upon topography of biceps and its synergists.…”

“…Sites that yielded MEPs between 0 to 25%, 25 to 50%, 50 to 75% and 75 to 100% of MEP Maxima were categorized in different levels- level I, II, III and IV. To graphically represent map volume, we developed contour and three-dimensional plots [69].…”

“…It has been shown that repetitive motor tasks cause intracortical synaptic reorganization, and increase cortical excitability [6], possibly through the induction of shortterm and long-term synaptic potentiation (LTP) mechanisms [7]. Based on these premises, repetitive transcranial magnetic stimulation (rTMS), a non-invasive brain stimulation technique able to induce LTP-like plastic adaptations of corticospinal neurons, appears as an interesting tool to promote motor recovery.…”
