Effect of Surgeon Warm-up and Mental Visualisation During Robot-assisted Laparoscopic Surgery

In the researchers' words

Study Design - A Counterbalanced Study Aims - To determine the effect of a) warm-up exercises and b) mental visualisation on the musculoskeletal demands and cognitive demands respectively during robot-assisted laparoscopic surgery. Outcome Measures - 1. EMG measurements of frequency and amplitude across muscle fibres. 2. EEG measurements of peak alpha power, and alpha spindle duration and amplitude. Study Participants and Eligibility - Surgeons who have certificates of completion of training (CCT) and performing surgical procedures using the minimally invasive techniques of RALS. Planned Size of Sample - The investigators have chosen the higher value for our power calculation (an effect size of 0.24) which requires 10 surgeons per condition performing 1 - 2 operations for 80% power to detect a difference between conditions, at an alpha of 0.05. Planned Study Period-Duration - Each surgeon will be required to participate in the study for approximately 3 - 4 weeks performing 3 surgical procedures and based on estimates that surgeons routinely perform an average of 1 robotic procedure per week it is anticipated the study will run for 6 months. Research Question - Does structured simulated warm-up exercises prior to performing surgery improve surgeons' ergonomic awareness and maintain the low muscle fatigue impact associated with RALS? The investigators also hypothesize…
