An interventional study of Vibrotactile Stimulation in Cough, sponsored by University of Minnesota. Recruiting at 1 site in United States. Open to participants aged 18 Years to 88 Years. Per ClinicalTrials.gov, last updated 2026-06-15.
Sponsored by University of Minnesota · Not applicable, Interventional, and Treatment
Researchers will test the effect of non-invasive vibrotactile stimulation of the larynx on symptom severity of unexplained chronic cough.
142 studies on the registry are indexed under Chronic Cough; 39 are open to participants now.
This study's planned enrollment of 60 is close to the median of 60 across 104 interventional studies indexed under Chronic Cough.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

Device: Vibrotactile Stimulation
Small electric motors, similar to a vibrating cell phone or gaming joystick, deliver vibration to the throat. Participants will assess cough symptoms throughout the study period.
