In order to establish the reductions in performance resulting from pregnancy a group of 27 healthy pregnant women were investigated parallel to a comparable control group of non-pregnant women with a test combination, which consisted of the tachistoscopic test on scope of comprehension and minimum recognition time, the evaluation of the attentiveness quotient according to Gruener, and the establishment of performance on performance test equipment and in the motor-performance series according to schoppe (mls). In connection with the clinical controls 7 tests were carried out before the birth, at first every four weeks and later at two week intervals. The eighth and final test took place 6 to 8 weeks after the birth. The reduction in performance resulting from pregnancy can be deduced by setting the control test results at 100 per cent and relating to this the appropriate results from the pregnant women. It was shown that with scope of comprehension, the attentiveness quotients according to gruener and in four single tests in the motor performance series according to schoppe (tapping, replacing of short sticks, replacing of long sticks, driving along a line), with advanced pregnancy an almost continuous reduction in performance became apparent. This reached a maximum (9.07 per cent to 37.42 per cent) mainly in the final investigation before the birth. A distinct decline in the performance limitations after the birth is characteristic and is a demonstrative feature of the conditioning effect of pregnancy on these performance reductions. In the minimum recognition time, in the motor performance (mls) sub-test "aiming" and on the performance-test equipment no significant variations or only small performance reductions became apparent. In the discussion on the traffic/medical consequences it may not be possible from the performance reductions to assume without question that all pregnant women are incapable of driving. Nevertheless the very clear reductions in performance at present appear to justify the recommendation. (TRRL)
