Summary
Paradoxical vocal-cord dysfunction (PVCD) can mimic exercise-induced asthma (EIA) in athletes. Early diagnosis by athletic trainers is crucial for proper treatment and avoiding unnecessary asthma medications.
Area of Science:
- Sports Medicine
- Pulmonology
- Otolaryngology
Background:
- Paradoxical vocal-cord dysfunction (PVCD) involves the vocal cords closing during inhalation.
- This condition is often misdiagnosed as exercise-induced asthma (EIA), leading to incorrect treatment.
- Athletic trainers are key in identifying PVCD due to its presentation in athletes.
Purpose of the Study:
- To discuss a case of paradoxical vocal-cord dysfunction (PVCD).
- To highlight the importance of considering PVCD in athletes with suspected exercise-induced asthma (EIA).
- To emphasize the role of athletic trainers in diagnosing and managing PVCD.
Main Methods:
- Case report presentation.
- Detailed patient history collection from an athlete.
- Clinical suspicion and diagnostic evaluation for PVCD.
Main Results:
- A case of paradoxical vocal-cord dysfunction (PVCD) was successfully diagnosed.
- Treatment for exercise-induced asthma (EIA) was discontinued.
- Appropriate treatment for PVCD was initiated, leading to symptom improvement.
Conclusions:
- Athletic trainers can significantly contribute to the diagnosis of PVCD.
- PVCD should be considered in athletes unresponsive to EIA medication.
- A high index of suspicion is vital for healthcare professionals evaluating athletes with respiratory symptoms.
