Work-related musculoskeletal disorders (WMSDs) are common amongst neurosurgeons and can affect a surgeon's ability to operate. Performing surgical ergonomics research is important to minimize the prevalence and effect of WMSDs on the surgeons. The aim of this review is to highlight some of the most important objective and subjective tools available for surgical ergonomics research. Subjective tools can be divided into three categories: (1) questionnaires (either validated or non-validated) filled out by the participants, (2) survey assessments/standardized scoring systems filled out by the researchers, and (3) video analysis. Subjective tools have the drawbacks of recall bias and intra-rater and inter-rater variability. Some of the most important objective tools available are surface electromyography, force plate/pressure sensors analysis, inertial measurement units (IMUs) and kinematics data capturing using reflective markers. Although these modalities do not have the drawbacks that hinder the use of subjective tools, using most of them in the real-life operating theatre, with the exception of IMUs, is challenging. Conducting surgical ergonomics research is important to optimize the performance of neurosurgeons. The advancements towards wearable, wireless technologies will make it easier for surgeons to perform ergonomics research in the operating room.
