Clinical Trial Summary

Intensive care unit (ICU)-acquired weakness (ICU-AW) is one of the most common complications of post-ICU syndrome. It is the leading cause of gait disturbance, decreased activities of daily living, and poor health-related quality of life. The early rehabilitation of critically ill patients can reduce the ICU-AW. We designed a protocol to investigate the feasibility and safety of conventional rehabilitation with additional in-bed cycling/stepping in critically ill patients. The study is designed as a single-center, open-label, pilot, randomized, parallel-group study. After the screening, participants are randomly allocated to two groups, stratified by mechanical ventilation status. The intervention group will be provided with exercises of in-bed cycling/stepping according to the level of consciousness, motor power, and function in addition to conventional rehabilitation. In contrast, the control group will be provided with only conventional rehabilitation. The length of the intervention is from ICU admission to discharge, and interventions will be conducted for 20 minutes, a maximum of three times per session. The primary outcome is the number and percentage of completed in-bed cycling/stepping sessions, the duration and percentage of in-bed cycling/stepping sessions, and the number of cessations of in-bed cycling/stepping sessions. The secondary outcomes are the interval from ICU admission to the first session of in-bed cycling/stepping, the number and percentage of completed conventional rehabilitation sessions, the duration and percentage of conventional rehabilitation sessions, the number of cessations of conventional rehabilitation sessions, the number of adverse events, level of consciousness, functional mobility, muscle strength, activities of daily living, and quality of life. This study is a pilot clinical trial to investigate the feasibility and safety of conventional rehabilitation with additional in-bed cycling/stepping in critically ill patients. If the expected results are achieved in this study, the methods of ICU rehabilitation will be enriched.

Secondary	the confusion assessment method for the ICU (CAM-ICU)	The CAM-ICU is a short test for the diagnosis of delirium in adult patients in critical care settings. As a tool to evaluate the presence of delirium, it is evaluated by four characteristics. Trait 1 is characterized by acute changes in mental state or fluctuating mental state, trait 2 is characterized by attention deficit, trait 3 is characterized by unsystematic thinking, and trait 4 is characterized by changes in the level of consciousness. The presence of delirium is when the trait 1 and trait 2 are present, and trait 3 or trait 4 is present.	baseline-ICU discharge (an average of 3 weeks)
Secondary	Richmond agitation-sedation scale (RASS)	RASS is a valid and reliable assessment tool to measure the level of alertness and agitated behaviour in critically-ill patients.	baseline-ICU discharge (an average of 3 weeks)
Secondary	Functional ambulation category (FAC)	FAC is a 6-point functional gait test that assesses walking ability to determine how much support a patient needs when walking, with or without a personal assistive device. Nonfunctional gait is scored as 0, level 2 dependent gait is scored as 1, Level 1 dependent gait is scored as 2, supervised independent gait is scored as 3, independent gait on a flat surface is scored as 4, and independent gait anywhere is scored as 5.	baseline
Secondary	Functional status score (FSS-ICU)	a 5-item to measure physical function for patients in ICU and consists of 5 categories: rolling, supine-to-sit transfers, unsupported sitting, sit-to-stand transfers, and ambulation.

In the static balance, four items will be evaluated: stand unsupported, stand feet together, stand on toes, and tandem stand with eyes closed. And walking will be evaluated two items: walking distance and walking independence. In the dynamic balance, three items are evaluated pick up pen from floor, walks 4 steps backwards, jump. The DEMMI is considered an important characteristic of independent mobility and includes items that have validity in measuring the mobility domain defined by the World Health Organization. Using a simple conversion table for 15 evaluation items, it can convert ordinal mobility score (out of 19) into interval mobility score (out of 100).	baseline-ICU discharge (an average of 3 weeks)-hospital discharge (an average of 2 months)-1 month after the hospital discharge (an average of 3 months)
