Interventions
Behavioral: Rehabilitation therapy
Behavioral: placebo injection
Procedure: Glossopharyngeal Nerve Block
Registration Number
NCT06328205
Lead Sponsor

Brief Summary

The goal of this clinical trial is to explore Clinical Effect of Glossopharyngeal Nerve Block on Pharyngeal Dysphagia Induced by Gastroesophageal Reflux Disease. The main question it aims to answer is:

• Can Glossopharyngeal Nerve Block improve dysphagia caused by gastroesophageal reflux symptoms on the basis of rehabilitation training? Participants will be randomly allocated into the control group or the experimental group, all under rehabilitation treatment, the experimental group will be given Glossopharyngeal Nerve Block once a day additionally. The study lasts 20 days for each participant. Researchers will compare the Rosenbek penetration-aspiration scale, Gastroesophageal Reflux Disease Questionnaire, Pressure pain threshold, to see if the Glossopharyngeal Nerve Block can help improve the symptom.

Detailed Description

Gastroesophageal reflux is a common digestive disorder characterized by the backflow of stomach contents and fluids into the esophagus.

Primary Outcome Measures
NameTimeMethod
penetration-aspiration scaleday 1 and day 10

This assessment evaluated the patient's swallowing of contrast medium and whether there was retention, penetration, and aspiration. It included multiple items, each with the corresponding criteria, Specifically, whether the swallowed material entered the airway, passed through or contacted the vocal cords, and whether the patient exhibited the corresponding ability to clear.

The scores range between one to eight, with higher levels indicating more severe outcomes of aspiration.

Secondary Outcome Measures
NameTimeMethod
Pressure pain thresholdday 1 and day 10

Pressure is applied on the spinous processes of the fourth cervical vertebrae. Pressure will be uniformly increased, and patients are given the identical instruction, "let me know when the sensation of pressure becomes uncomfortable or painful". At this point, the pressure will be immediately released, and the plunger is retracted by the evaluator. And the pressure will be recorded

Gastroesophageal Reflux Disease Questionnaireday 1 and day 10

The Gastroesophageal Reflux Disease Questionnaire is a commonly used questionnaire for assessing the symptoms and severity of gastroesophageal reflux disease. It was developed by gastrointestinal experts in Germany and consists of six questions that evaluate the frequency and severity of gastroesophageal reflux disease symptoms. For each question, patients are required to select the answer that best corresponds to their situation. Different scores are assigned based on the chosen answers, and a total score is calculated at the end.

The maximum score for the Test is 12 points, with a lower score indicating milder symptoms and a higher score indicating more severe symptoms.
