Interventions
DEVICE

repetitive transcranial magnetic stimulation (Magstim Super Rapid stimulator, The Magstim Company Ltd, Whitland, UK)

The paradigm will be applied over the dominant cerebral hemisphere for 10 minutes (600 pulses) over the dominant pharyngeal motor cortex capped at 120% of pharyngeal resting motor threshold.

DEVICE

pharyngeal electrical stimulation (Digitimer model DS7; Welwyn-Garden City, Herts, UK)

The PES (0.2-ms pulses, 280 V) was delivered at a set frequency (5 Hz), intensity (75% of maximal tolerated), and duration (10 minutes), which have been reported as the most effective parameters for PES.

DEVICE

sham repetitive transcranial magnetic stimulation(Magstim Super Rapid stimulator, The Magstim Company Ltd, Whitland, UK)

Sham rTMS is delivered with the coil tilted to its side at 90 degrees and with the identical stimulation conditions as active 1 Hz rTMS.

DEVICE

sham pharyngeal electrical stimulation (Digitimer model DS7; Welwyn-Garden City, Herts, UK)

For sham pharyngeal stimulation, the same method including the insertion of the catherter will be employed without actual electrical stimulation.
