Central (CCT) and peripheral (PCT) conduction time. A–D: group and individual data [control, n = 14; spinal cord injury (SCI), n = 15] shows the CCT and PCT during precision grip and power grip when the TMS coil was oriented in the latero-medial (LM), posterior-anterior (PA), and anterior-posterior (AP) directions in controls (A and B) and in individuals with SCI (C and D). B and D show individual data on PA-LM and AP-LM MEP latency differences for precision grip and power grip in controls (green) and SCI (orange). Subjects showing changes in opposite direction as those described by green and orange circles are shown in gray. Error bars indicate SD. *P < 0.05, comparison between tasks.
