Laparoscopy is used in many surgical specialties. Subjective reports have suggested that performing laparoscopic surgery patients with a high body mass index (BMI) leading to increased prevalence of musculoskeletal symptoms surgeons. The aim this study was objectively quantify the impact on surgeon upper kinematics and dynamic workload when simulated laparoscopy at different BMI levels.Upper novice, intermediate expert surgeons were calculated based measurements from inertial measurement units positioned segments. Varying thicknesses foam simulate patient BMIs 20, 30, 40 50 kg/m2 during training.Significant increases jerkiness, angular speed cumulative displacement head, torso arms found within all experience groups subject models. Novice less controlled larger workloads compared more experienced surgeons.Our findings indicate model worsens motion efficiency efficacy, workload, producing conditions are physically demanding operating 20 model. These also suggest torso, arm segments especially affected by models therefore exposure may increase risk injury surgery.
