About this trial
This is an interventional treatment trial for Dysphagia focused on measuring stroke, cervical spinal cord injury
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:

classical electrical stimulation protocol
revised sequential activation 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.
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.
