Clinical trials

The purpose of this multi-site prospective study is to assess validity of a new step test called Functional-Incremental Stepping-in-place- Test (F-IST) compared to gold-standard cardiopulmonary exercise testing (CPET) and to physical function and health perception, respectively. The investigators will also assess test-retest reliability of the F-IST. The investigators hypothesize that the F-IST will have high validity and test-retest reliability to be used in field testing environments such as the ICU.

This project is designed to have patients participate in a virtual environment with various tasks such as breathing exercises, games to help the brain, and techniques that promote relaxation while hospitalized in the Intensive Care Unit (ICU). The participation in research will last about 5 days and take about 15 to 45 minutes each day.
