Background: Cycle ergometry is a rehabilitation strategy used in the intensive care unit (ICU) which may help mitigate post-ICU impairments. We aimed to systematically review and summarize evidence examining the efficacy and safety of cycle ergometry in the ICU.
Methods: We included randomized controlled trials (RCTs) of critically ill adults with any diagnosis admitted to the ICU for >24 hours, comparing cycling interventions to control (no cycling).
Purpose: Physical rehabilitation (PR) in the intensive care unit (ICU) may improve outcomes for survivors but clinical trial results have been discordant. We hypothesized that discordant results may reflect treatment heterogeneity received by "usual care" comparator groups in PR studies. Usual-care PR is typically underspecified, which is a barrier to comparing results across treatment studies.
