The Motor Imagery Based on Action Observation Treatment on Dysphagia in Wallenberg Syndrome
Condition: Lateral Medullary Syndrome; Deglutition Disorders
MeSH terms: Deglutition Disorders; Lateral Medullary Syndrome; Syndrome
Study type: Interventional

Summary: 
      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.

        -  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.
    

Intervention name(s): conventional dysphagia treatment; motor imagery based on action observation treatment
Intervention type(s): Other; Other
Intervention description(s): 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.
