title: Methodological infrastructure in surgical ergonomics: a review of tasks, models, and measurement systems.
abstract: Though in its infancy, the discipline of surgical ergonomics is increasingly valued. Still, little has been written regarding this field's tasks, models, and measurement systems. These 3 critical experimental components are crucial in objectively and accurately assessing joint and postural control as exhibited by expert laparoscopic surgeons. Such assessments will establish characteristic patterns important for surgical training. In addition, risk factors associated with both minimally invasive surgical instruments and the operating room environment can be identified and minimized. Our review focuses on evidence-based experimental ergonomic studies undertaken in the field of laparoscopic surgery. Publications were located through PubMed and other database and library searches. This article describes tasks, models, and measurement systems and considers their specific applications and the types of data obtainable with the use of each. Advantages and limitations, especially those of measurement systems, are compared and discussed. Future trends and directions believed necessary for optimal investigation and results are also addressed.
