Inclusion criteria

Inclusion criteria: Inclusion Criteria for the Case Group: Age between 30 and 80 years old. Meet the diagnostic criteria for stroke and have a first-time onset. Have been assessed as having dysphagia. Be conscious and have stable vital signs, and be able to cooperate in completing the relevant examinations for this study. Willingly sign the informed consent form for this study. Inclusion Criteria for the Healthy Control Group: Age between 30 and 80 years old. Be able to smoothly swallow 30 milliliters of warm water in one go within 5 seconds, without obvious aspiration, and without experiencing choking, suffocation, or other symptoms of swallowing difficulty during the process. Have no history of stroke or other neurological diseases. Willingly sign the informed consent form for this study.

Exclusion criteria

Exclusion criteria: (1) Presence of other neurological diseases (such as Parkinson's disease, Alzheimer's disease, multiple sclerosis, etc.). (2) Abnormal anatomical structures of the pharynx and larynx or postoperative lesions (such as after laryngeal cancer surgery, patients with tracheostomy). (3) Presence of severe cardiopulmonary dysfunction or other terminal illnesses. (4) Presence of psychological or cognitive impairments that prevent cooperation with the examination. (5) Pregnant or breastfeeding women, or those planning to conceive in the near future. (6) Presence of contraindications to cricopharyngeal electromyography, such as patients with a tendency to bleed, those with a pacemaker or cardiac defibrillator, and those prone to recurrent or systemic infections. (7) Presence of contraindications to contrast-enhanced CT, such as patients allergic to iodine-containing contrast agents, those with hyperthyroidism, severe renal insufficiency, or diabetic patients taking biguanide medications.
