Comparative efficacy of trans cranial direct current stimulation and conventional therapy in post thermal inhalation dysphagic children and adult patients: A randomized controlled trial

the current study aimed to investigate the effect of adding Trans cranial direct current stimulation (tDCS) to the conventional therapy of treating post thermal inhalation injury dysphagia. Methods: Thirty patients complaint from post thermal inhalation injury dysphagia were participated in this study, their ages were ranged from 13 to 60 years. They were randomly divided into two equal groups. Group (A): Received 3 weeks of treatment with (tDCS), 2-mA current was delivered for only 30 s through 2 surface electrodes three times/week in addition to the conventional therapy. While Group (B): Received 3 weeks of treatment with conventional physical therapy plus sham (tDCS). Functional Oral Intake Scale (FOIS) and The Mann Assessment of Swallowing Ability (MASA) were used to assess the swallowing ability in both groups before and after the intervention.
