Paradoxical Vocal Fold Movement (PVFM)
[
en Español]
What is PVFM?
Paradoxical vocal fold movement (PVFM) is a voice disorder.
The vocal folds (cords) behave in a normal fashion almost all of
the time, but, when an episode occurs, the vocal cords close when
they should open, such as when breathing.
What are signs and symptoms of PVFM?
PVFM can be mistaken for asthma as it leads to wheezing and
difficulty breathing, sometimes to the point of requiring
hospitalization.
How is PVFM diagnosed?
PVFM is often diagnosed by a team of professionals,
including:
- speech-language pathologist
- neurologist
- pulmonologist
- otolaryngologist (Ear, Nose, and Throat doctor)
- psychologist
Diagnosis is difficult because symptoms vary greatly between
people. Episodes are not predictable. The team will review the
person's medical history, including medications and smoking
history. A laryngeal evaluation using endoscopy (passing a scope
into the throat to view the vocal cords) is typically done. A
voice evaluation by an SLP also aids in diagnosing this
disorder.
What treatments are available for PVFM?
PVFM is treated both medically and behaviorally. Medical
intervention addresses any physical and/or psychological factors.
Behavioral intervention with an SLP includes vocal exercises,
relaxation techniques, and proper breath support for speech. The
goal of intervention is to make the individual aware of what
triggers PVFM so they can avoid those situations. The person is
also taught how to handle an episode when it occurs.
