Patient-centered REhabilitation Program to Advance REcovery

A lightweight mobile/web application delivering a patient-centered prehabilitation program from randomization until surgery. Features include: weekly home six-minute walk tests (6MWT) logged in the app; brief daily check-ins for exercise performed, simple nutrition targets, and mood/stress; push reminders; short educational video/handout content; and CSV export for analysis. The app provides standardized instructions and safety prompts for the home 6MWT and basic validity checks (continuous 6 minutes, pause limits, outlier flags). No additional study-specific clinic visits are required beyond routine preoperative admission and one routine postoperative outpatient visit.

Standard perioperative counseling/education and routine mobilization per institutional ERAS practice. No study app is provided and no remote 6MWT logging is required. Outcome assessments are collected at routine preoperative admission (including in-hospital 6MWT per protocol) and at one routine postoperative outpatient visit (≈3 or 6 months per unified site policy). No additional study-specific clinic visits are required.
