Current Pulse Amplitude:
Pulse Rate:
Maximum Voltage:
Multipulse:
Max. number of pulses in a burst while maintaining limit of: 125 mJ/s
Note: Transcranial MEP stimulation exceeds 2 mA rms/cm2. Ensure that the corkscrew
electrodes are secure prior to starting stimulation.
As shown in the chart, Transcranial MEP stimulation is limited to 125 mJ/sec. The chart
allows the user to estimate the number of pulses permitted given a current voltage (based
on an impedance of 1 kΩ).
