Assess the Safety and Efficacy of the 4 Channel NMES, Pilot Study
Study Details
Study Description
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 effect by the electric stimulation method 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(N=9)
-
Intervention: Participants are divided into two group and applied electrical stimulation by a "Synchronized Electrical Stimulation Device(SESD)" in different protocol
-
Main outcome measures: high-resolution manometry(HRM) parameters, videofluoroscopic parameters, EQ-5D (EuroQoL-5D) questionnaire
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: classical electrical stimulation protocol apply 4 channel electrical stimulation device with protocol 1. It will simultaneously stimulate suprahyoid, thyrohyoid and sternothyroid m with 4 channel electrical stimulation device. during apply the device, we evaluate the manometry and videofluoroscopic swallowing study for evaluation of deglutition function. |
Device: 4 channel Electrical Stimulation Device
electrical stimulation at muscles which related with deglutition
|
| Experimental: revised sequential activation protocol apply 4 channel electrical stimulation device with protocol 2 Is a revised sequential activation protocol, it sequentially stimulate bilateral suprahyoid m (channel 1), pharyngeal constrictors (ch 2), thyrohyoid m (ch 3), sternothyroid m (ch 4) with 4 channel electrical stimulation device. during apply the synchronized electrical stimulation device, we will evaluate the parameters same as group 1. |
Device: 4 channel Electrical Stimulation Device
electrical stimulation at muscles which related with deglutition

Outcome Measures
Primary Outcome Measures
- pressure change [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.)]
- videofluoroscopic dysphagia scale [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.]
total score 100 from 0, 100 is worst outcome
