Effects of interference current stimulation with t-DCS on swallowing function

JRCT ID: jRCTs042220162

Registered date:24/03/2023

Basic Information

• Recruitment status: Recruiting
• Health condition(s) or Problem(s) studied: Patients with pharyngeal dysphagia, and healthy adults
• Date of first enrollment: 01/04/2023
• Target sample size: 60
• Study type: Interventional
• Intervention(s): Twenty minute interference current stimulation and/or 20 minute t-DCS intervention in healthy adults. Swallowing monitor(B4S) is used for analysis. Twenty minute interference current stimulation once a day, for seven days and/or 20 minute t-DCS intervention once a day for four days in ten hospital days. Swallowing monitor(B4S) and Videofluorography are used for analysis.

Outcome(s)

• Primary Outcome: the numbers of swallowing reflex and the onset times of each repetitive saliva swallowing reflexes on RSST

Secondary Outcome

Immediate effects ; Stage transition duration, distance of hyoid bone and larynx during swallowing reflex, penetration aspiration scale using VF findings
Short term effects: dysphagia severity scale,eating status scale,functional oral intake scale
