title: [Restatement and conception of an experimental battery of measurements of displacements in the three planes of a vertebral unit].
abstract: The study of motions of a vertebral unit is difficult because of the great number of participating structures. Analysis in the three planes is required to obtain optimal visualization of the entire spectrum of criteria involved. Initially, we used comparators to achieve these measurements. However, the complexity and number of parameters quickly led us to switch to electronic sensors. At present, a completely automated test bench has been developed using an Orion data processing chain. Decoding and interpretating results nevertheless remains difficult in such tridimensional analyses.
