About this trial
Hospital immobility leads to serious complications including muscle loss, weakness, delirium, pressure ulcers, and blood clots. Despite being medically stable, hospitalized patients spend over 90% of their time in bed due to staffing shortages, fall risks, and limited physical therapy availability. Within one week of admission, patients can lose approximately 2% of thigh muscle mass per day, and nearly half develop clinically significant hospital-acquired weakness.The Bedside Bike is a portable, low-resistance exercise device that clamps securely to hospital beds, allowing patients to perform leg and arm cycling exercises safely without leaving their bed. This study will evaluate whether hospitalized patients at Indiana University Health facilities can feasibly and safely use the Bedside Bike to maintain mobility during their hospital stay.This quality improvement study will enroll 80 adult inpatients expected to stay at least 3 days. All participants will receive the Bedside Bike in addition to usual care (standard physical therapy and medical treatment). The study will measure how often patients use the device, whether it is safe (tracking any device-related problems), and whether it may help improve outcomes such as hospital length of stay, functional mobility scores, discharge to home, and rates of hospital-acquired weakness. Participants will have functional assessments at admission and discharge, use the Bedside Bike throughout their hospitalization (targeting at least 15 minutes daily), and be followed for 60 days after discharge to track readmissions, falls, living arrangements, and mortality.
