The purpose of this study is to better understand how one-sided (unilateral) vocal cord paralysis affects the lives of patients across the country. Participants are asked to complete 4 or 5 surveys at specific intervals over a 6-month period. The CoPE Collaborative consists of 48 academic medical centers located across the United States. To join the study, participants must be referred by a participating CoPE provider. Participants also need to have been diagnosed with one-sided vocal cord paralysis, have access to the internet, have an email address, be at least 18 years old, and speak English. If you are interested in the study, please request a brochure from your provider or contact the research study staff. For more information, visit copestudy.org.
