NCT04199936

Brief Summary

Patients lose a significant amount of muscle following major abdominal surgery. This is partly due to a catabolic response to the surgical insult and inflammation, but is also probably due to a lack of muscle use secondary to immobility. This study will aim to assess whether some or even all of postoperative muscle loss in the upper leg muscle group is preventable through electrical muscle stimulation to mimic physical activity.
