Improvement of mobility and motivation in patients with elective colorectal resection using tracking devices and utilizing self-awareness (IMPETUS): a randomized controlled trial in a traditional non-ERAS clinical setting

Background Early postoperative mobilization is a cornerstone of modern perioperative care, including in elective colorectal surgery. Here we evaluated the effectiveness of smart wearables for improving patients’ mobility and motivation during the recovery period after elective colorectal resection. Methods This prospective randomized two-armed clinical trial enrolled 62 patients undergoing elective colorectal resection. These patients were randomized into an intervention group that received hourly active reminders to mobilize via a smartwatch, and a control group that received only passive monitoring. All patients were given a wearable device that tracked their daily step counts. The primary end-point was the total number of steps taken within five postoperative days. Secondary end-points included complication rates, length of hospital stay, and subjective motivation, assessed using a structured questionnaire. Results Compared to the control group, the intervention group achieved significantly higher step counts ( p = 0.039), and reported increased motivation for mobilization ( p = 0.016). The groups did not significantly differ in overall complication rates or duration of hospital stay. Conclusion Smart wearable devices with hourly active reminder functionalities effectively promoted postoperative mobility and motivation.
