About this study
Official title: Effect of Transcranial Direct Current Stimulation Combined With Oral Feeding on Dysphagia: A Randomized Controlled Study
The study is a double-blind randomized controlled trial, lasting for 15 days for each participant. Patients with post-stroke dysphagia who receive treatment at the Rehabilitation Department are selected as the study subjects. The patients are randomly assigned to either the experimental group or the placebo group. All patients receive routine rehabilitation therapy and swallowing rehabilitation training, along with enteral nutrition support using Intermittent Oro-esophageal Tube. In addition to these interventions, patients in the experimental group receive transcranial direct current stimulation, while the instruments used for patients in the placebo group only illuminate an indicator light without any actual effect.
Read the detailed description
Transcranial direct current stimulation is currently very popular. The study is a double-blind randomized controlled trial, lasting for 15 days for each participant. Patients with post-stroke dysphagia who receive treatment at the Rehabilitation Department are selected as the study subjects. The patients are randomly assigned to either the experimental group or the placebo group. All patients receive routine rehabilitation therapy and swallowing rehabilitation training, along with enteral nutrition support using Intermittent Oro-esophageal Tube. In addition to these interventions, patients in the experimental group receive transcranial direct current stimulation, while the instruments used for patients in the placebo group only illuminate an indicator light without any actual effect.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Comprehensive rehabilitation therapyBehavioural
Including： Basic treatment, including corresponding control of risk factors and education on healthy lifestyles.
Swallowing training, including lemon ice stimulation, empty swallowing training, and pronunciation training.
Pulmonary function training, including standing training, cough training, and diaphragm muscle training.
Intermittent Oro-esophageal Tube FeedingDevice
All patients are given enteral nutritional support with Intermittent Oro-esophageal Tube according to the following procedure: Before each feeding, inside and outside of the tube was cleaned with water. During feeding, the patient should maintain a semi-reclining or sitting position with mouth opened, and the tube was inserted slowly and smoothly into the upper part of the esophagus by medical staffs while the appropriate depth of intubation was checked with the calibration markings on the tube wall. The distance from the incisors to the head part of the tube should be between 22-25 cm. However, the specific depth should be evaluated based on patients' feedback and adjusted accordingly. After insertion, the tail part of the tube should be put into a container full of water and the absence of continuous bubbles indicated a successful intubation. Then, the feeding was to be conducted three times per day with 50 ml per minute and 400-600ml for each feeding.
Transcranial direct current stimulationDevice
In this study, transcranial direct current stimulation is performed using a battery-powered constant current stimulator. This device delivers the current through two electrodes immersed in saline solution. Specifically, a 50mm*50mm anodal electrode pad is placed at the center of the healthy side swallowing sensory-motor cortex of the patient. According to the positioning method of the international 10-20 electrode system, the swallowing sensory-motor cortex of the left brain is located at the midpoint between C3 and T3, while that of the right brain is located at the midpoint between C4 and T4. The cathode is placed on the opposite shoulder, using a current of 1mA, once a day, for 20 minutes each time, and 5 days a week. The instruments used for placebo patients will not have any actual effect.

What is being measured
The primary outcome is the main question the study is designed to answer.
Penetration Aspiration Scale
Penetration-Aspiration Scale is used to measure swallowing safety, which is also the primary outcome of this study. Before and after treatment, patients are required to undergo a swallow study to complete the assessment. This scale evaluates the patient's swallowing function level and aspiration risk by assessing leakage and aspiration during the patient's swallowing process. The results are divided into eight levels, with higher levels indicating poorer swallowing function and lower swallowing safety.
Measured: day 1 and day 15
Secondary outcomes (6)
Functional Oral Intake Scale
During Dysphagia-Functional Oral Intake Scale assessment, evaluators engage in communication with the patient, conduct observations, and make records to assess the patient's oral intake ability. The Functional Oral Intake Scale assessment form includes seven levels of scoring, ranging from level 1 to level 7, indicating a progressive improvement in the patient's oral intake ability. In general, the result below level 6 indicates unsafe for oral intake while level 6 and above indicates that eating via mouth can be safely conducted.
Measured: day 1 and day 15
Swallowing Quality of Life Questionnaire
The Swallowing Quality of Life Questionnaire (SWAL-QOL) is used to evaluate the impact of swallowing function on patients' quality of life. The questionnaire consists of 44 questions related to swallowing function and quality of life. Each question is answered using a 5-point rating scale. In this study, the final score is converted into a percentage. The higher scores indicate the better quality of life.
Measured: day 1 and day 15
Patient Health Questionnaire-9
To assess the patients' depression levels, a questionnaire is used. The questionnaire consists of 9 questions related to depressive symptoms, and each question is answered using a 4-point rating scale. The total score ranges from 0 to 27, with higher scores indicating a greater tendency towards depression.
Measured: day 1 and day 15
Body weight
Body weight measurement of the infants was conducted by the same nurse according to the relevant standards.
Measured: day 1 and day 15
Nutritional status-total protein
The relevant indicators include total protein (TP, g/L) from the blood test within 24h after admission and the last day of treatment, generally, with empty-stomach infants and in the morning.
Measured: day 1 and day 15
Nutritional status-albumin
The relevant indicators include albumin (ALB, g/L)from the blood test within 24h after admission and the last day of treatment, generally, with empty-stomach infants and in the morning
Measured: day 1 and day 15
