Ergonomic Assessment of Hand Movements in Laparoscopic Surgery Using the CyberGlove

The main objective of this chapter is the automation of the ergonomic assessment of the wrist’s positions, through biomechanics analysis techniques, specifically using the rapid upper limb assessment (RULA). So, this allows establishing new use and design guidelines of the laparoscopic instruments, in order to reduce the influence of risk factors in the wrist area, which are associated with forced positions during the development of laparoscopic activities.

Objective assessment based on motion-related metrics and technical performance in laparoscopic suturing

PurposeThe aim of this study is to present the construct and concurrent validity of a motion-tracking method of laparoscopic instruments based on an optical pose tracker and determine its feasibility as an objective assessment tool of psychomotor skills during laparoscopic suturing.MethodsA group of novice (

Motion analysis metrics were recorded using the proposed tracking method, which employs an optical pose tracker to determine the laparoscopic instruments’ position. Construct validation was measured for all 10 metrics across the three groups and between pairs of groups. Concurrent validation was measured against a previously validated suturing checklist. Checklists were completed by two independent surgeons over blinded video recordings of the task.ResultsEighteen novices, 15 intermediates and 11 experienced surgeons took part in this study. Execution time and path length travelled by the laparoscopic dissector presented construct validity. Experienced surgeons required significantly less time (
