Degenerative discopathy is a common pathology that may require spine surgery. A metallic cylindrical pin is inserted into the vertebral body to maintain soft tissues and may be used as a reflector of ultrasonic wave to estimate bone density. The firs

A method to synchronise cameras using the direct linear transformation technique
Autor: Didier Geiger, J.-M. Denoix, Philippe Pourcelot, Christophe Degueurce, Fabrice Audigié
Publikováno v: Journal of Biomechanics. 33:1751-1754
The aim of this paper is to present a method which enables the recordings of cameras that are not equipped with a synchronisation system to be synchronised a posteriori. Using the Direct Linear Transformation technique, this method estimates the phas

Kinematic analysis of the locomotion symmetry of sound horses at a slow trot
Autor: Didier Geiger, Christophe Degueurce, J.-M. Denoix, Fabrice Audigié, Philippe Pourcelot
Publikováno v: Equine Veterinary Journal. 29:93-96
This study of the locomotion symmetry was undertaken to provide standard symmetry indices of a group of sound horses at the trot. Using a 3D data collection system, the kinematics of the limb joints of 13 clinically nonlame horses were recorded while

Variability of the limb joint patterns of sound horses at trot
Autor: J.-M. Denoix, Fabrice Audigié, Didier Geiger, Christophe Degueurce, Philippe Pourcelot
Publikováno v: Equine Veterinary Journal. 29:89-92
The reproducibility of gait variables for sound horses is essential for the interpretation of their modifications by locomotor disorders. Therefore, the purpose of this study was to evaluate the variability of the limb joint angle patterns in a popul

Mechanical behaviour of fibroblast-populated ordered collagen-gel
Autor: L. Besseau, Didier Geiger, M.M. Giraud Guille, E. Fernandes, Christian Oddou, Salah Ramtani
Publikováno v: Proceedings of the First Joint BMES/EMBS Conference. 1999 IEEE Engineering in Medicine and Biology 21st Annual Conference and the 1999 Annual Fall Meeting of the Biomedical Engineering Society (Cat. No.99CH37015).
Collagen gels with fibroblasts can contract with the traction exerted by these cells on collagen fibres, without external loading. The purpose of this study is to characterize the mechanical properties of these gels.
