Abstract
Objective: Randomized controlled trials (RCTs) using neuromuscular electronic stimulation (NMES) andnon-invasive brain stimulation (NIBS) were applied for early access to clinicians included in a post-strokeswallowing intervention. A meta-analysis of the research will provide concrete effects and suggestions forimprovement.

Methods: We searched articles from 2008 to 2019 published in Pubmed, CINAHL (EBSCOhost), Psycinfo, KoreanStudies Information Service System (KISS), and the Research Information Sharing Service (RISS). The main keywords are ¡°stroke OR CVA OR cerebrocascular accident OR vascular accident¡± AND ¡°dysphagia OR swallowingdisorder OR deglutition disorder¡± AND ¡°tDCS OR transcranial direct current stimulation OR rTMS OR repetitivetranscranial magnetic stimulation OR NMES OR neuromuscular electronic stimulation¡± AND ¡°RCT OR randomizedcontrol trial,¡± ¡°³úÁ¹Áß¡± AND ¡°¿¬ÇÏÀå¾Ö,¡± AND ¡°°æµÎ±â ÀÚ±âÀÚ±Ø OR °æµÎ°³ Á÷·ùÀÚ±Ø OR ½Å°æ±ÙÀü±âÀڱء± AND ¡°¹«ÀÛÀ§´ëÁ¶½ÇÇè.¡± The inclusion and exclusion criteria were applied to a total of 11 studies.

Results: The electrical stimulation intensity of transcranial direct current stimulation (tDCS) was 1 mA, theelectrical stimulation intensity of repetitive transcranial magnetic stimulation (rTMS) was 3-5 Hz, theneuromuscular electrical stimulation (NMES) varied from 8 to 15 mA, tDCS and rTMS showed large effect sizes,and NMES demonstrated a medium effect size.

Conclusion: This study confirmed the effects of three treatments through a meta-analysis and confirmed thevarious results according to the patients' characteristics and mediation direction. However, three treatments aredeemed effective for the recovery of swallowing disorder after a stroke in Korea and are considered safe. Inaddition, it is necessary to study various factors leading to a recovery of a swallowing disorder.
