Postoperative Electrical Muscle Stimulation Two
NCT06964438
Summary
Undesirable loss of skeletal muscle mass (atrophy) is a common feature of many diseases as well as ageing, bed rest and physical inactivity. Losing muscle can lead to a reduction in one's ability to perform physical activities, and reduce independence and overall health. Muscle mass loss occurs very quickly (i.e., within a few days) after surgery. The investigators previous work has shown that neuromuscular electrical stimulation (NMES) of the thigh muscles on one side of the body can help maintain muscle mass and strength on the stimulated side after surgery. Since then, additional work has been carried out to find the most effective form of stimulation to build muscle. The current study aims to use this refined stimulation protocol in a clinical trial on the wards after major abdominal surgery. The intervention will involve delivering stimulation to both thighs in the few days after surgery, so that the investigators can assess whether this stimulation can preserve muscle mass and strength, and also, patients' ability to perform physical activities after surgery. In addition, the study will aim to find out whether any benefit provided by electrical stimulation can be increased further by taking a protein supplement at the same time.
