Methods	Method of randomisation unclear Baseline prognostic factors balanced between treatment groups
Participants	1 centre in Korea 25 participants; baseline characteristics similar Enrolment within 6 weeks of stroke onset Clinical and videofluoroscopic evidence of dysphagia
Interventions	Rx: additional exercise programme for dysphagia with thermal‐tactile stimulation C: thermal‐tactile stimulation only Treatment for up to 2 months
Outcomes	Videofluoroscopy, Functional Oral Intake Scale, transition from tube to oral feeding, incidence of aspiration pneumonia
Notes	Exclusions: previous history of other diseases, which may have caused dysphagia; severe cognitive disorder, such as dementia; inability to carry out videofluoroscopy due to incapability of sitting posture; inability to follow study instructions
