A high-risk ergonomic situation is created by the assistant's left or caudal leg disproportionately bearing 70-80% of body weight over time. A distance increase between the camera head location and the camera holder increases ergonomic risk. The phase effect was interpreted as a compensatory rebalancing to reduce ergonomic risk. Ergonomic solutions minimizing ergonomic risks associated with laparoscopic assistance should be considered.

“…The Dundee Endoscopic Psychomotor Tester (DEPT) [1] with a target plate specially designed for the study was used for objective assessment of endoscopic task performance. Aspects of face validity of DEPT to endoscopic surgery includes the use of standard video-endoscopic equipment and the movement of the probe in the gambal, which has the same degrees of freedom as endoscopic instruments through the access ports.…”

“…Subjects performed a virtual aiming task (see Figure2(b)), developed from a pilot study ], with the goal of reaching for and touching a small target with a virtual tool tip controlled by [Hanna et al 1996] and studying the role of visual cues in virtual aiming performance [Tendick et al 2000]. In our task, the tool tip had to touch the surface of the virtual target cube before the trial was considered complete.…”

Visual information is important in surgeons' manipulative performance especially in laparoscopic surgery where tactual feedback is less than in open surgery. The study of surgeons' eye movements is an innovative way of assessing skill, in that a comparison of the eye movement strategies between expert surgeons and novices may show important differences that could be used in training. We conducted a preliminary study comparing the eye movements of 5 experts and 5 novices performing a one-handed aiming task on a computer-based laparoscopic surgery simulator. The performance results showed that experts were quicker and generally committed fewer errors than novices. We investigated eye movements as a possible factor for experts performing better than novices. The results from eye gaze analysis showed that novices needed more visual feedback of the tool position to complete the task than did experts. In addition, the experts tended to maintain eye gaze on the target while manipulating the tool, whereas novices were more varied in their behaviours. For example, we found that on some trials, novices tracked the movement of the tool until it reached the target.

Abstract: DEPT provides a standard, reproducible, objective real-time scoring system. It identifies individuals who cannot adjust to endoscopic viewing and therefore manipulate from endoscopic images.
