Ergonomic Comparison of back function tests
In this work we have showen a comparision between two methods of measuring the back function, because it is still unclear exactly what the back function tests actually measure. Back lifting and extension tests (isometric back extension endurance) are commonly used methods in value judgment of work ability and rehabilitation. Some new devices (isokinetic apparatus) are now in the use which could help in the more descriptive judgment of human's back mechanical capacity. Previous isometric measurements that we have done eariler, are here as control group of data, but they were reffered to the measuring of lumbal moments which depended on pulling forces, and inclination of the trunk, as well as the age of subjects. The new isokinetic devices now incorporated what we call today active dynamometry. In a such devices servo motors and microprocessors transformed the early machines into fast and dynamic tools offering instant data analysis and reproducibility. This change in the fundamental data collection process finally sparked large scale interest in isokinetic testing. Using this method we found out that is possible to get out results which performance is mainly influenced on heredity and behavioral factors i.e. it assesses the physical capacity for lifting, which means that it may prove difficult to alter isokinetic lifting capacity by interventions, what indicates that behavioral factors may play more influential roles.
