About

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.

Full description

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.
