The current recommendation in most patient information is to reduce core muscle activity in the postoperative period to prevent incisional hernia, one of the most common problems after abdominal surgery. However, there is no proof to back up the claim that incisional hernias are more common when the core muscles are active. In contrast, it is expected that a decrease in physical activity will cause sarcopenia, chronic postsurgical pain (CPSP), and physical deconditioning.
