Treatment of Paradoxical Vocal Fold Motion Disorder (PVFMD) With a Form of Respiratory Retraining Technique
NCT02859974 · View on ClinicalTrials.gov ↗
Study Summary
Paradoxical Vocal Fold Motion Disorder (PVFMD), otherwise known as vocal cord dysfunction (VCD) is a laryngeal breathing disorder that has several potential causes. In some individuals, exertion is the predominant trigger. PVFMD can present like an asthma attack, but asthma medication is ineffective in treating it. The effects of untreated PVFMD can be devastating, leading to harmful, invasive, and ineffective treatments over a period of years. Numerous anecdotal reports indicate that several behavioral techniques, may be surprisingly effective and even curative. However, data are lacking. The form of respiratory retraining technique tested in the current study educates people with PVFMD about breathing and teaches them a number of breathing exercises specially designed to restore normal breathing patterns. This case series study will use a dyspnea perception questionnaire, patient daily logs, and physiological measurements of heart rate and breathing to examine whether this form of therapy can improve exertion-induced PVFMD symptoms.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT02859974
The ClinicalTrials.gov registry entry for NCT02859974 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 15 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Boston Medical Center, which has 192 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Vocal Cord Dysfunction appearing as the primary indexed condition, and to 1 intervention — of which Respiratory retraining for PVFMD is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT02859974 reports 1 study location spanning 1 distinct geographic area — top geographies include Massachusetts. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
