ClinConnect Summary

This clinical trial is looking at whether using an ultrasound scan on the vocal cords can help identify a condition called inducible laryngeal obstruction (ILO). In ILO, the vocal cords narrow or close when a person breathes in, which can make it really hard to breathe. The study aims to find out if this ultrasound method is effective for detecting such narrowing in patients who might have breathing difficulties, especially those with conditions like vocal cord dysfunction or asthma.

To participate in the study, you must be a healthy adult aged between 65 and 74, with no signs of vocal cord issues, voice changes, or a history of throat surgeries. If you have any known vocal cord problems or have had surgeries in the head or neck area, you won't be eligible. If you decide to join, you can expect to undergo a simple ultrasound scan of your vocal cords, which is painless and quick. This study is currently recruiting participants, and your involvement could help improve how doctors assess breathing issues related to the vocal cords in the future.
