- •
TMS-elicited motor-evoked potentials (MEPs) are highly variable.
- •
We examined the number of trials required for a reliable estimate of MEP amplitude.
- •
∼20–30 trials were required to ensure reliability both within and between sessions.
- •
Stimulating with more than 30 trials provided no additional benefit.
- •
30 trials may be optimal for estimating corticospinal excitability using TMS.
