This protocol is performed at 120% of motor threshold. The train(s) consist of 40 pulses: 10 pulses a second for a total of 4 seconds, followed by a break of 11.0 seconds. This is repeated 75 times. The total duration is 18 minutes 26 seconds, and the total number of pulses is 3000.

Pulse frequency in train (Hz)	10
Pulses in train	40
Number of trains	75
Intertrain interval(s)	11.0
Total time	00:18:26
Total pulses	3000
