Summary

The primary objective of this study is to investigate whether the dual transcranial direct current stimulation(tDCS) improves the swallowing function of stroke patients.

Detailed description

120 patients were recruited and randomized to receive either real or sham-tDCS. Real experimental groups were divided into three types; Anode-Anode dual stimulation group, Anode-Cathode dual stimulation group, Single stimulation group. 20-minutes session of the stimulation were applied 5 times a weeks for 2 weeks at pharyngeal motor cortex of affected or non-affected site. The patients were evaluated at baseline, immediately and 2 weeks after tDCS.
