Rebuilding Inter-limb Transfer in Cervical SCI

PCMS + Contralateral Motor Training will involve delivering 360 pairs of TMS-PNS pulses (30min, 0.2 Hz) to the weaker first dorsal interosseous (FDI) muscle immediately before a session of ballistic index finger abduction training at the opposite, stronger FDI muscle.

PCMS + Rest will involve delivering 360 pairs of TMS-PNS pulses (30min, 0.2Hz) to the weaker FDI followed by a 30-min rest.

360 TMS pulses will be delivered at a location 10-cm posterior to the participant's head (into the air, 0.2Hz) and no PNS pulses will be generated, followed by a session of 30-min ballistic index finger abduction training at the opposite, stronger FDI muscle.
