The Safety and Efficacy of the 4 Channel NMES on Swallowing

Study Overview
=================
Brief Summary
-----------------
This study is a pilot study to prepare clinical trials to evaluate the safety and effectiveness of 4-channel electric stimulation therapy devices as a newly developed function for the treatment of dysphagia disorders. The purpose of this study is to investigate the difference in 4ch NMES and 2ch NMES, And to obtain the values such as mean, standard deviation and so on, and to determine the number of subjects to be studied for clinical trials of validation permission in the future.

Detailed Description
-----------------
Design: Prospective study Inclusion criteria of patient group: who has a dysphagia symptom and confirmed by video-fluoroscopic swallowing study Intervention: Participants are divided into two group and applied electrical stimulation by a Synchronized Electrical Stimulation Device(SESD) in 4channel or 2channel Neuromuscular Electrical Stimulation. Main outcome measures: videofluoroscopic parameters, EQ-5D (EuroQoL-5D) questionnaire, II. M. D Anderson dysphagia inventory

Eligibility Criteria
-----------------
Inclusion Criteria: patient who do not belong to the criteria excluded for subjects aged 19 years or older Patient who is confirmed to be dysphagia by videofluoroscopy Patients who need clinical application of electrical stimulation therapy equipment for dysphagia. ex) stroke, cervical spinal cord injury Those voluntarily agreeing to the clinical trial Exclusion Criteria: Patient who refuse inspection, do not agree Simple Commend obey, first step is impossible When instructions can not be executed due to dementia, psychiatric disorders, etc. Dysphagia occurs due to respiratory failure, neck surgery, etc., Pregnant women and lactating women

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| videofluoroscopic dysphagia scale | total score 100 from 0, 100 is worst outcome | baseline/ change from baseline when electrical stimulation applied(the object of this study is to know the temporary change of dysphagia when stimulating with 4ch NMES. |
