This study looks at how the brain works during swallowing in people with Lateral Medullary Syndrome (LMS), which is a type of stroke that affects swallowing. The researchers want to see how brain activity and connections change when people with LMS swallow, compared to healthy people. They use a special tool called functional near infrared spectroscopy (fNIRS) to do this. fNIRS helps them watch the brain’s activity without being invasive.

To join the study, participants must be aged 18-80, right-handed, have had their first stroke as LMS, and have swallowing problems confirmed by a video test. They also need to be aware enough to take part in the tests and not have other serious illnesses or mental health issues.

• The study is observational, which means no treatment is given.
• Participants will need to go through brain activity tests using fNIRS.
• No compensation or risks are outlined in this description.
