Early Mobilization Following Elective Spine Surgery: Trial of In-bed Cycling

The goal of this clinical trial is to learn if early mobilization using an in-bed cycling device can reduce the amount of time patients spend in bed after elective spine surgery in adults. The main questions it aims to answer are: Does in-bed cycling on the day after surgery reduce the amount of time patients spend in bed over the next 24 hours? Does in-bed cycling reduce the length of hospital stay and improve participation during physiotherapy assessment? Researchers will compare patients who receive an in-bed cycling session plus standard postoperative care to patients who receive standard postoperative care alone to see if early in-bed cycling improves mobility and recovery after spine surgery. Participants will: Be randomly assigned to either a standard care group or an in-bed cycling group Wear a fitness tracker to measure activity levels and time spent in bed Receive standard postoperative care Complete a 30-minute in-bed cycling session on the day after surgery (intervention group only) Be monitored for pain and vital signs during the study period Undergo a physiotherapy assessment to evaluate mobility and participation
