An exploratory study on optimal conditions for the effects of peripheral sensory nerve electrical stimulation on excitation of the corticospinal tract - An exploratory study on optimal conditions for the effects of peripheral sensory nerve electrical stimulation on excitation of the corticospinal tract

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.
