Clinical Utility of the 1-minute Sit to Stand Test as a Measure of Submaximal Exercise Tolerance in Patients With Cystic Fibrosis During Acute Pulmonary Exacerbation

Not Applicable

Completed

• Conditions: Cystic Fibrosis
• Interventions: Diagnostic Test: Sit to stand test

• Registration Number: NCT04058548
• Lead Sponsor: Boston Children's Hospital

Brief Summary

The aim of this study is to assess whether the 1 minute Sit to Stand (STS) test can be used as a measure of submaximal endurance during a pulmonary exacerbation of Cystic Fibrosis (CF) for patients in the acute care setting. We hypothesize that if the STS test is a valid measure of submaximal cardiovascular endurance, it will moderately correlate with 6 minute walk distance (6MWD).
