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.

Gaze disruptions experienced by the laparoscopic operating surgeon

“…In addition, Weigmann's study pertains to an open, not laparoscopic, surgical procedure. The well-described unique and increased demands posed by the MIS approach [9][10][11] could also account for our study's higher event rate.…”

Ergonomic risk associated with assisting in minimally invasive surgery

“…In a recent literature review, these evidence-based experimental ergonomic studies were discussed in detail, including examination of their methodological infrastructures (e.g., tasks, models, measurement systems) [13]. Additionally, the obtained data and specific applications covered in these ergonomic studies were summarized.…”

“…Motion analysis and force plates have been among the tools used to examine surgeons' body movements, specifically the measurement and analysis of postural sway [13]. Upper body movements have been characterized by Person et al [14], who demonstrated the feasibility of using an optoelectric measurement system for automated posture sampling in the study of surgical ergonomics.…”

Higher physical workload risks with NOTES versus laparoscopy: a quantitative ergonomic assessment

“…Physical workload assessments while performing laparoscopic tasks have been achieved using a variety of biomechanical methodologies [19]. Motion analysis systems have allowed researchers to reconstruct surgeons' body movements in 3D and calculate kinematic data such as joint angles and velocities.…”
