Abstract

Background/Objectives: Minimally invasive surgery benefits patients but places phys-ical and cognitive demands on surgeons. While robot-assisted laparoscopic surgery (RALS) reduces musculoskeletal strain, it may increase cognitive load. This study ex-amined whether physical and psychological preparatory protocols (warm-ups) influence surgeon strain during RALS. Methods: Ten consultant surgeons from East Lancashire Hospitals NHS Trust (UK) participated in a preregistered, randomized study. Each performed RALS under three conditions: control, physical warm-up (10-minute simu-lation tasks on the Da Vinci system), and psychological warm-up (10-minute PETLEP-based mental imagery). Electromyography (EMG) and electroencephalography (EEG) were recorded during key surgical phases. EMG data were normalized to maximal voluntary contractions. Results: The physical warm-up significantly increased EMG ac-tivity in the right deltoid and right trapezius (p<0.05) compared to control, with no dif-ferences observed in other muscle groups. EEG alpha power did not significantly differ between conditions. Conclusions: These findings suggest that brief physical warm-up can enhance muscle activation in key regions involved in RALS, potentially improving motor control and reducing fatigue. Incorporating such strategies may support surgeon performance and well-being.
