In the 1990s, Enhanced Recovery after Surgery (ERAS) was first described in general surgery by the Danish surgeon H. Kehlet [Most published studies did not emphasize on pain, subjective outcome and mobility. Moreover, no scientific high-quality study in a controlled study design was published.

Activities are: Getting up/Personal hygiene/Going to the toilet/Dressing/Sitting and Walking. The postoperative days are abbreviated as Day 1/Day 2 and so on
