The MEP Monitor can be used with a MagPro R30+X100 magnetic stimulator as a medical tool intended to assist in the electrophysiologic monitoring, description and evaluation of muscles, nerves and of structures in the central nervous system in normal and pathological conditions and as an aid for MagVenture TMS Therapy to determine the patient’s individual Motor Threshold (MT). The MEP Monitor is a one channel EMG amplifier mounted on the back of the MagPro, optimized for Motor Evoked Potentials (MEP).
