lumbar spine; biomechanical capacity of lumbar spine

Sažetak
In order to prevent low back pain it is important to find loads that are related with high risk for occurrence of this injury. Many scientists have been occupied with this problem using many different approaches to find some relevant data. Awareness of this problem complexity identify approach to this problem through mechanical capacity of lumbar spine, which is defined as an ability of lumbar spine system to prevail the applied load without risk of loosing mechanical stability. In order to solve problems of obtaining the mechanical capacity of lumbar spine, biomechanical analysis of interrelated influential factors is performed with the intention to obtain the results by using measurements that are applicable to wide range of human postures and related working tasks in sagittal mid-plane, considering anthropometrical measures. Measurement device MedX is chosen considering that isometric lumbar extension moment measurement procedure allows application of measuring results for static and dynamic loads and fact that the isolation of trunk is necessary. The results obtained by such measurement procedure provide full mechanical capacity magnitude of lumbar spine. This allows an interpretation of different static and dynamic loads and the magnitude of applied loads on lumbar spine, reduced on sagittal mid-plane. A measurement procedure evolved lumbar extension moment as a function of trunk angle. Magnitude of mechanical capacity of lumbar spine depends on posture, circumstances of applied loads and anthropometrical measures, which in calculation of its magnitude represent the need to establish biomechanical model for every analysed case. Mechanical capacity of lumbar spine as described offers path in future handling loads magnitude determination, so it have important contribution to occupational ergonomics, biomechanics and medical sciences.
