“…7 However, electromagnetic sensors were chosen in our experiment because of their ability to provide data in burdened areas, as well as their small size, which made their embedment not interfere with intraocular surgical procedures. Optical sensors require a line of sight difficult to guarantee during intraocular surgery, given the limited space of maneuver.…”

Purpose Robot assistance in ocular microsurgery could improve precision, dexterity, save time or prevent complications by task automation, and provide access to ocular surgery in undeserved countries by teleoperation. However, to design robotic devices, the range of motion of surgical instruments needs to be precisely quantified. Methods An electromagnetic tracking system was developed for intraocular surgery in order to quantify the movements of ophthalmic surgeons. Kinematics of surgical steps during phacoemulsification and pars plana vitrectomy procedures were determined by measuring the maximum translation and angular range of motion of intraocular surgical tools in the three planes. Conclusion Important variations in amplitudes of rotation and translation were measured between both hands and between surgical tasks. These parameters may be used to develop a robotic intraocular surgical system or to improve training.

“…Bergmann et al (2009) reported that body-worn, inertial motion sensors are a practical, non-constraining alternative to optical motion analysis. Examples of their use in research studies include analysis of hip joint flexion and extension during human walking gait (Saber-Sheikh et al, 2010); assessment of spasticity assessment in children with Cerebral Palsy (Van den Noort, 2009); and measurement of lumber, hip, knee and ankle joint angles of skiers (Kondo et al, 2012). Cloete and Scheffer (2008) compared inertial motion capture of human gait kinematics against optical motion capture (n=8), demonstrating good reliability for hip and knee joint angle flexion.…”

This is an author-created version of a manuscript accepted for publication in AbstractEquestrian sports report three to five times higher incidence rates for lower back pain than that of the general population, with hip flexion angles of 50-60° suggested as a causal factor. Inertial motion capture technology enables dynamic measurement of rider kinematics but data extraction is time-consuming. The aim of this study was to develop a software tool to automate the process of extracting biomechanical data from the Xsens TM MVN (MoCap) system to investigate postural changes in riders, comparing static position at halt with dynamic position during the sit phase of rising trot. The software was found to be efficient, reducing data extraction time by 97% when used with a sample of 16 riders. Good correlation was found between hip flexion and pelvic anterior-posterior rotation and between halt and trot but with significantly greater values of hip flexion and pelvic anterior rotation in trot. No riders showed hip flexion >50° at halt but 11 riders (69%) showed hip flexion >50° during the sit phase of rising trot, indicating that dynamic assessment is important when considering rider postural faults that may put them at risk of back injury.
