Electrical stimulation is performed by changing the stimulation conditions (frequency and stimulation time).
Three random conditions are selected out of nine combinations of frequency (1, 10, and 50 Hz) and stimulation time (20, 40, and 60 min) for every case.

Each participant experienced three different stimulation frequencies (1, 10 and 50 Hz) and durations (20, 40 and 60 min). The outcome measure was the change in primary motor cortex excitability using the MEP ratio. We defined the optimal combination within nine different settings inducing more satisfying responses. The combination of stimulation frequency and stimulation time that maximized the desirability value was 10 Hz and 40 min, respectively.

The participants included 21 healthy individuals (5 men and 16 women; mean age, standard deviation, 21.7, 0.6 years). The inclusion criteria were age > 18 years and right-handedness. Individuals with a history of neurological or orthopedic disorders were excluded.
Twenty-one participants experienced three different stimulus settings randomly decided in advance. No participants dropped out, and all participants were included in the analysis.
There were no adverse events.
