CYCLE: A Randomized Clinical Trial of Early In-bed Cycling for Mechanically Ventilated Patients

Brief Summary

Patients who survive critical illness usually experience long-lasting physical and psychological impairments, which are often debilitating. Rehabilitation interventions started in the ICU may reduce this morbidity. In-bed cycling, which uses a special bicycle that attaches to the hospital bed, allows critically ill patients who are mechanically ventilated (MV) to gently exercise their legs while in the ICU. The main goal of this study is to determine whether critically ill MV adults recover faster if they receive early in-bed cycling than if they do not. Another objective is to determine whether in-bed cycling is a cost-effective intervention. 360 patients admitted to the ICU and receiving MV will be enrolled in the study. Following informed consent, patients will be randomized to either (1) early in-bed cycling and routine physiotherapy or (2) routine physiotherapy alone. Patients' strength and physical function will be measured throughout the study. If early in-bed cycling during critical illness improves short-term physical and functional outcomes, it could accelerate recovery and reduce long-term disability in ICU survivors.
