Abstract:

Objective To study the effects of transcranial direct current stimulation (tDCS) in different intensities on dysphagia after cerebral infarction and its neurological mechanism.Methods From January, 2016 to December, 2018, 60 inpatients with dysphagia after cerebral infarction were randomly equally divided into low-, medium- and high-intensity groups, in which the intensities of tDCS were 1.0 mA, 1.5 mA and 2.0 mA, respectively, for 30 days. They were observed with video fluoroscopic swallowing study and α waves of electroencephalography before and after treatment. Results The score of oral stage increased in the high-intensity group after treatment (t = -2.196, P < 0.05), while the dominant frequency of α wave increased ( t = -6.488, P < 0.001). Conclusion High-intensity tDCS may improve the excitability of the brain for patients with dysphagia after cerebral infarction, to improve the swallowing.
