Dysphagia in Inflammatory Muscle Diseases: Answering the Questions Who, Where, Why and What to Do?

This study is examining swallowing difficulties (called dysphagia) in people with inflammatory muscle diseases, including conditions called inclusion body myositis, dermatomyositis, and polymyositis. These conditions can weaken the muscles involved in swallowing, making eating and drinking difficult and potentially dangerous. The study aims to better understand where the swallowing problem is occurring, why it happens, and how best to treat it. Participants will undergo swallowing assessments to map out their specific difficulties.
