This document discusses paradoxical vocal fold motion (PVFM), also known as vocal cord dysfunction. It describes PVFM as a condition where the vocal folds adduct during inhalation and/or exhalation, causing upper airway obstruction. Common signs and symptoms include asthma-like breathing difficulties and sensations of tightness in the laryngeal area. At-risk populations tend to be women ages 20-40 with over 12 years of education working in healthcare. Differential diagnosis requires a multidisciplinary evaluation. Treatment involves patient education, speech therapy, and in rare cases surgery. The document also discusses considerations for voice therapy with transgender clients.
