The goal of this clinical trial is to learn about on dysphagia in wallenberg syndrome. The main questions it aims to answer are: * the efficacy of motor imagery based on action observation treatment in the rehabilitation of patients with dysphagia in Wallenberg syndrome. * apply functional near infrared spectroscopy to explore the mechanism of action of this therapy. Participants received conventional dysphagia treatment and motor imagery based on action observation treatment once a day for 14 days. Researchers compared the control group to see the effect and mechanism of motor imagery based on action observation treatment.
The goal of this clinical trial is to learn about on dysphagia in wallenberg syndrome. The main questions it aims to answer are: * the efficacy of motor imagery based on action observation treatment in the rehabilitation of patients with dysphagia in Wallenberg syndrome. * apply functional near infrared spectroscopy to explore the mechanism of action of this therapy. Both groups received conventional dysphagia treatment, and the experimental group underwent the addition of motor imagery based on action observation treatment to the control group once a day for 14 days. Overall swallowing function was assessed before treatment and after 14 days of intervention. Meanwhile, the functional near infrared spectroscopy was used to detect changes in cerebral hemodynamics during the execution of volitional swallowing task and swallowing motor imagery.

Conventional dysphagia treatment included oropharyngeal muscle movement training, orofacial alternating hot and cold stimulation, Masako swallowing training, Mendelsohn maneuver, therapeutic ingestion training, intermittent oral-esophageal tube feeding, and low-frequency electrical stimulation of swallowing neuromusculature, etc., 30 min each time, once a day for 14 consecutive days.
First, the therapist explained the purpose and principle of the intervention method to the patient, keeping the surrounding environment quiet and comfortable to avoid the patient's mood fluctuations due to external interference. Then start the treatment, the video recorded in advance was given to the patient to watch, the playback device is a ipad. The content includes lip and tongue muscle relaxation exercises, healthy people eating, chewing, swallowing, drinking and other images. At the same time, the guidance was played, which was consistent with the content in the video. The video was played 3 times consecutively for 30 min each time, once a day for 14 days.

standardized swallowing assessment
The standardized swallowing assessment was used to assess the improvement of overall swallowing function, it has a maximum score of 46 and a minimum score of 18, with lower scores indicating better swallowing function.
Time frame: day 1 and day 14
cortical activation during volitional swallowing
The functional near infrared spectroscopy system (Nirsmart, Danyang Huichuang Medical Equipment Co., Ltd., China) was used to detect changes in cerebralhemodynamics during the execution of volitional swallowing task.
Time frame: day 1 and day 14
cortical activation during swallowing motor imagery
The functional near infrared spectroscopy system (Nirsmart, Danyang Huichuang Medical Equipment Co., Ltd., China) was used to detect changes in cerebralhemodynamics during the whole swallowing motor imagery.
Time frame: day 1
Murray secretion scale
The severity of Murray secretion scale was measured using a grade of 0-3, patients without obvious saliva accumulation are scored as MSS grade 0, whereas patients who had secretions in the laryngeal vestibule at the start of the exam were assigned grade 3.
Time frame: day 1 and day 14
yale pharyngeal residue severity rating scale
Yale pharyngeal residue severity rating scale scores were measured using a 5-point ordinal scale: Ⅰ = none, Ⅱ = trace, Ⅲ = mild, Ⅳ = moderate, Ⅴ = severe.
Time frame: day 1 and day 14
Rosenbek penetration-aspiration scale
The highest PAS score is 8 and the lowest is 1 (1 = no entry of material into the airway; 2 - 5 = penetration of material past the laryngeal additus into the supraglottic space and traveling as far as the true vocal folds; 6 - 8 = tracheal aspiration of material below the true vocal folds).
Time frame: day 1 and day 14
swallowing-quality of life
Swallowing-quality of life has a score range of 44 - 220, with lower scores indicating poorer swallowing function and poorer quality of life.
Time frame: day 1 and day 14
