[Functional radiography of the lumbar spine. I. History and method of dynamic tests].

Abstract

The relevancy of functional radiographies of the lumbar spine (extension-flexion; inclinations) was determined by using radiographies of patients (n = 36), radiographed following a standardized technique. As well the total as the segmental movement amplitude of the lumbar spine were examined. As to the segmental mobility, in this first publication the criteria are sought to define hyper- and hypo-mobility. When one handles these criteria, the correlation with the clinical findings will be examined and this is the subject of a second publication in progress.
