Pedometer Coaching to Promote Postoperative Ambulation
The goal of this randomized controlled trial is to evaluate whether remote pedometer follow-up and virtual coaching can improve ambulation after major abdominopelvic surgery, and how this affects key postoperative outcomes.

The main questions it aims to answer are:

Does pedometer-guided ambulation coaching increases ambulation after surgery?
Does pedometer-guided coaching improve satisfaction, quality of recovery, while reducing postoperative complications?

Participants will be asked to install a pedometer app for the purpose of data sharing. Study personnel will compare pedometer follow-up plus text message coaching (intervention) with pedometer follow-up only (control) to investigate whether coaching improves adherence to the postoperative ambulation recommendation, and whether this leads to improvement of the secondary outcomes.
