**Intermittent Oro-esophageal Tube Feeding** is a method used to help feed patients who have trouble swallowing, known as **dysphagia**. This study is looking at people with **Parkinson's disease**, a condition that affects movement and can cause swallowing issues. Researchers are comparing two feeding methods: **Intermittent Oro-esophageal Tube Feeding** and **Nasogastric Tube Feeding**. They want to see which method helps improve nutrition, swallowing, and daily activities better. **Nasogastric Tube Feeding** involves putting a tube through the nose into the stomach but can have complications. The study also looks at whether a procedure called **stellate ganglion block** might help improve the patients' conditions. **Key Points:** - Participants will be divided into two groups, receiving different types of tube feeding. - Routine therapy and nutritional support will be provided to all participants. - The study will evaluate the effects on nutrition, swallowing, and daily activities. Eligible participants must be over 18, diagnosed with Parkinson's disease and dysphagia, and able to cooperate with treatment. They cannot have other conditions that might affect swallowing or severe organ failures.
