BRacelet And Physical actiVity Evaluation (BRAVE)

Evaluation of Pre- and Post-operative Physical Activity on Postoperative Rehabilitation After Colorectal Surgery With a Connected Device

The aim of this study is to quantify pre- and postoperative physical activity of patients operated on colorectal surgery. Daily physical activity (No. of footsteps) is going to be recorded from 15 days before surgery to the end of hospitalization after surgery in a prospective cohort of consecutive colorectal patients by use of an attached strap. Then, the investigators will propose physical activity thresholds (adapted to the age, gender and patient comorbidities) to optimize the ERAS protocol (Enhanced Rehabilitation After Surgery). Thus, this analysis will allow the investigators to provide patients with physical rehabilitation programs "a la carte" during a hospitalization for colorectal surgery. Connected bracelets will directly involve patients in their care and rehabilitation.

Connected bracelet will be given to 50 consecutive patients undergone colorectal surgery 15 days before surgery. The investigators will measure pre- and postoperative physical activity. It is an observational activity of patient's physical activity during the perioperative period with no intervention.
