Trial summary

The hyperventilation syndrome is a quite frequent pathology, affecting up to 10% of the general population and 40% of the asthmatic population. Its physiopathology is still badly known and even if it is a benign affection, its associated comorbidities and symptomatology greatly decrease the patients' quality of life.

About this study

Official title: Impact of Respiratory Rehabilitation on Quality of Life, Measures by the SF-36 Score, in Patients With Hyperventilation Syndrome: Crossover, Prospective and Randomized Study

The hyperventilation syndrome is a quite frequent pathology, affecting up to 10% of the general population and 40% of the asthmatic population. Its physiopathology is still badly known and even if it is a benign affection, its associated comorbidities and symptomatology greatly decrease the patients' quality of life. Yet, no medicinal treatments have been proved useful, but prescribers noticed improvements after physiotherapy. Given that the physiotherapy impact on hyperventilation syndrome is not well described in the literature, this study aims to scientifically ascertain physiotherapy benefits on quality of life and symptomatology in hyperventilation syndrome-suffering patients.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of respiratory rehabilitation on Quality of life (time frame: Day 0). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04668638, which also lists 12 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
