Description of intervention(s) / exposure
Treatment: Devices - In-bed cycle ergometer (Restorative Therapies RT300 Supine)

Experimental: Early Cycling and routine physiotherapy - Patients will receive 30 minutes of in-bed cycling in addition to routine physiotherapy, 5 days per week, for the duration of their ICU stay

Active Comparator: Routine physiotherapy - Patients will receive routine physiotherapy per current institutional practice


Treatment: Devices: In-bed cycle ergometer (Restorative Therapies RT300 Supine)


Other interventions: Routine physiotherapy
activities to assist with optimizing airway clearance and respiratory function, and, based on the patient's alertness and medical stability, activities to maintain or increase limb range of motion and strength, in- and out of bed mobility, and ambulation

Summary
Brief summary
Background: Patients in the intensive care unit (ICU) are the sickest in hospital, and need
advanced life-support. Survivors of critical illness are very weak and disabled. Up to 1 in 4
have severe leg weakness impairing their quality of life for as long as 5 years after ICU
discharge. In-bed cycling involves use of special equipment that attaches to a patient's
hospital bed, allowing them gentle exercise while in the ICU.

Methods: Adult patients admitted to the ICU who need a breathing machine and are expected to
survive their ICU stay are eligible. Patients will randomly receive 30 minutes of in-bed
cycling each day they are in the ICU or routine physiotherapy, both delivered by specially
trained physiotherapists.

Outcomes: Feasibility: The investigators will study whether patients can cycle on most days
of their ICU stay, whether patients and their families agree to be a part of the study, and
whether investigators can systematically assess patients' strength.

Relevance: Effective methods of physiotherapy are needed for critically ill patients to
minimize muscle weakness, speed recovery, and improve quality of life. This pilot randomized
study is the second of several future larger studies about in-bed cycling in the ICU.

Our pilot work includes CYCLE Pilot and CYCLE Vanguard. CYCLE Pilot is an external pilot and
enrolled 66 patients from 3/2015 to 6/2016. CYCLE Vanguard is an internal pilot and enrolled
47 patients from 11/2016 to 3/2018. CYCLE Vanguard patients will be analyzed in the main
CYCLE RCT (NCT03471247).
