Introduction: Double-train stimulation for motor evoked potentials (MEP) consists of one train of testing stimuli and one train of facilitating stimuli. The optimal number of pulses per train has not been determined. We wanted to determine the optimal combination of pulse trains that produces the hi...

      ab: Introduction: Double-train stimulation for motor evoked potentials (MEP) consists of one train of testing stimuli and one train of facilitating stimuli. The optimal number of pulses per train has not been determined. We wanted to determine the optimal combination of pulse trains that produces the highest MEP amplitude. Methods: Double train stimulation was attempted in 10 patients. Stimulation trains of 4 + 4 stimuli, 2 + 7 and 7 + 2 stimuli were attempted. The MEP response from the right foot muscles was used to determine the amplitude. Additionally, the MEP amplitude obtained with a single train of 7 stimuli was compared to the double trains. Results: Trains with 7 + 2 pulses resulted in higher amplitudes than trains with 2 + 7 and 4 + 4 pulses. Single trains of 7 pulses resulted in amplitudes comparable to 2 + 7 double trains and amplitudes lower than 7 + 2 double trains. Conclusions: A longer initial train for testing and a shorter train for facilitation improved MEP responses. This can result in lower stimulation intensity and less patient movement due to MEP testing during surgery.
