Figure 4.

Motor evoked potentials elicited by cervicomedullary stimulation (CMEPs) during index finger abduction (black trace) and precision grip (red traces) in healthy controls and patients with SCI. Rectified traces of CMEPs are illustrated (A, C, E). The dotted vertical lines indicated the approximate time of CMEP onset and the CMEP responses diverge. Left figures represent data from the mean of all subjects (black bars) and individual subjects (open circles) (B, D, F). Note that the size of CMEPs decreased during precision grip compared to index finger abduction in healthy controls and in SCI patients with taking baclofen but remains unchanged in SCI patients without taking baclofen.
