Post-operative Electrical Muscle Stimulation to Stimulate Muscle Protein Synthesis in Humans

Sponsor: University of Nottingham

Summary

Skeletal muscle accounts for approximately 45-55% of total body mass in healthy adults and plays a pivotal role in whole-body metabolic health, locomotion and physical independence. Undesirable loss of skeletal muscle mass (atrophy) is, however, a common feature of many communicable and non-communicable diseases including ageing, bed-rest/immobilisation, cancer and physical inactivity. As such, the design of optimal strategies (e.g., different types of exercise) to "offset" these detrimental losses of muscle is a focus for both researchers and clinicians. One situation where losses of muscle mass occur very quickly (i.e., within a few days) is after surgery. However, at this time, most people (especially if they have had major abdominal or lower-limb surgery) are not able to perform exercise and as such a different strategy to maintain muscle mass needs to be found. It has been shown that electrical stimulation of the leg muscles can maintain muscle mass and function in patients after surgery. It is not however yet known, what the optimal electrical stimulation regime is to preserve muscle mass during situations of disuse. This study aims to examine the impact of three different electrical stimulation protocols on muscle building processes in individuals age-matched to those most commonly presenting for major abdominal surgery. This information will then be used in a clinical trial of surgical patients to see if it can preserve their muscle mass and function in the post-operative period.
