Functional capacity evaluation: Ecological validity of three static endurance tests.
Functional Capacity Evaluation's (FCE's) are designed to measure the functional capacity of injured workers. Static endurance tests are integrated aspects of FCE's. Little is known about the validity of the tests. In this study, three static endurance tests (overhead work, crouching and kneeling) of the Isernhagen Work Systems FCE are studied for ecological validity. By manipulating the environment in an experiment using three different conditions (normal, loud noise, high production requirement), the ecological validity of the tests was investigated. Results: the different conditions did not seem to influence the holding times, the perceived exertion and the productivity of the subjects. The results are discussed and it is concluded that the three static endurance tests meet conditions of ecological validity. In order to be able to state that the tests of the IWS FCE are ecologically valid, more research is needed to enable a generalization.
