Comparison of the performance of 3D camera systems II

Joint loading decreased by inexpensive and minimalist footwear in elderly women with knee osteoarthritis during stair descent

“…The automatic digitizing process, the 3-D reconstruction of the markers' positions, and the filtering of kinematic data were performed using Arena software. The accuracy of the full-volume test for the Optitrack System was performed, as suggested by Chiari et al (2005) (23), and the results showed errors of less than 5.6 mm, similar to the majority of the commercial systems usually used in biomechanics (24). Ground reaction forces were acquired by a force plate (AMTI OR-6 -1000) embedded in the floor at the end of the last stair step.…”

Assessment and Validation of a Methodology for Measuring Anatomical Kinematics of Restrained Occupants During Motor Vehicle Collisions

“…This is substantiated by the correspondingly low ∆Diag values indicating minimal optical distortion of the cluster during the dynamic event. A number of studies in the literature have been devoted to quantifying performance of commercially available OSS [8][9][10][11][12][13][14]. While single target error for the current study is at the low end of the reported range in the literature, it should be noted that current OSS technology is utilized for the current study.…”

“…The introduction of video-based optoelectronic stereo photogrammetry for PMHS impact loading is relatively recent, however, it has long been utilized in non-impact motion biomechanics applications such clinical gait analysis [5][6][7][8][9][10][11][12][13][14][15][16]. The objective in movement analysis is the reconstruction of anatomical motion in the global OSS reference frame (Figure 2), however, it is generally accepted that a primary limitation of such movement analysis is error in single target position data and the propagation of this error to the estimation of the desired anatomical motion [5,6].…”

International scientific consensus on medical plantar pressure measurement devices: technical requirements and performance

“…All the statements, recommendations, technical and methodological suggestions hereby reported are the result of: i) preliminary activities at the ISS regarding this specific issue [2,3]; ii) online activities within the i-FAB-PG moodle-based forum; iii) background/working material found in the literature [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]; iv) document revision, and final on-line survey.…”
