CMCT-APB
The latency of the MEPs was recorded in the APB by transcranial magnetic stimulation. The conduction time from the cerebral cortex mainly to the T1 motor segment was defined as the CMCT-APB; this was derived by subtracting the PMCT from the latency of the MEPs. CMCT-APB=28.1–15.75=12.35ms.
