Highlights ► We aim to identify optimal parameters for hand electrical stimulation to be used in neurorehabilitation. ► MG stimulation at a sensory level of 50 Hz and a motor level of 2 Hz proved to be effective. ► The induced motor cortical excitability increase lasts for a period of 1h post stimulation.
