Biomechanical analysis of the lumbar spine

Physiological mobility of the lumbar spine, as a very important biomechanical feature of this spinal segment, has been defined, i. e., physiological instability has been proven on a sample of 35 fresh cadaveric human lumbar spine specimens which were tested in experimental conditions of both centric and eccentric static loads. The presence of physiological instability or physiological mobility of the lumbar spine in the form of so colled relative oblique or tangential shifts has already been numerically quantified. The lumbar spine is continuously deformed throught the action of static centric and eccentric loads ranging from 0-1000 N(ewton). Using a very sensitive method for detecting the lumbar spine deformities, based on measuring the angle of deflection of the laser beam on the screen, angular shifts of the spinal vertebrae can be defined within the sensitivity range of 0 degree to 1 degree with a standard error of +/-0.1 degree.
