Standard deviations (SDs) of normalized peak-to-peak MEP amplitudes during motor imagery of right wrist extension at ERD 35% and ERD 70%, calculated by the online FFT or LIA algorithm. The SD of normalized peak-to-peak MEP amplitudes in Condition 4 “LIA, ERD35%” was smaller than that in Condition 2 “FFT, ERD35%.” Similarly, the SD of normalized peak-to-peak MEP amplitudes in Condition 5 “LIA, ERD70%” was smaller than that in Condition 3 “FFT, ERD70%.” Each line shows the result obtained from each participant. *p < 0.05. ERD, event-related desynchronization; FFT, fast Fourier transformation; LIA; lock-in amplifier; MEP, motor evoked potential
