Abstract
A new special second-generation computer-controlled device has been developed for measuring biomechanical characteristics of the lower part of the spine vertebras L1–L5 [1]. During straining and measurement of the rigidity of the sample as a whole it is also necessary to observe the movement of individual parts of the sample and to measure their mechanical resistances. The measurement of displacement and rotation of individual parts of the studied model was evaluated by optical methods based on the principle of moiré interferometry and fast Fourier transform [2]. During this device development and its verification the lumbar samples were replaced with a system of wooden rollers with system discrete rubber pads. The new computer-controlled device containing four stepper motors, four strain gauges and two CCD cameras.
