| Abstract Plastic surgeons report neck, shoulder and back pain after wearing loupes during operations. This research aimed to discover the inter-relation between factors leading to upper-limb discomfort e.g. viewing angle, stature, or height at which the operation is performed. Ten postures are simulated using digital human models. We then apply multi-objective optimization to characterize the posture of the surgeon in relation to musculoskeletal risk (defined using RULA). It is possible to predict RULA scores for the range of postures. This could be used to quantify risk assessment, particularly in the selection and fitting of loupes and the specification of working height for surgery. Adjusting the operating height could decrease neck flexion angle and reduce musculoskeletal risk. |
