Paradoxical vocal fold movement occurs when the vocal folds close instead of opening when you take a breath. This can lead to inspiratory stridor (a high-pitched noise when you breathe in) and a feeling of shortness of breath. It can also be difficult to talk during these episodes.
What Causes Paradoxical Vocal Fold Movement?
Paradoxical vocal fold movement occurs most commonly in moments of stress. For example, just before an important competition or performance. It can last minutes or sometimes hours. It can cause some people to faint because they feel like they cannot get enough air in. While frightening, it is not life-threatening. Most importantly, it is an involuntary behavior.
How Is Paradoxical Vocal Fold Movement Diagnosed?

How Is Paradoxical Vocal Fold Movement Treated?
