I have evaluated the sensitivity and specificity of the tests of posture reactions which are used in diagnostics of developmental motor disorders in infants and in indications to Vojta therapy (1, 2). For this I have used the documentation of the children examined at the department of physiotherapy at Teaching Hospital Royal Vineyard (FNKV). The examination concerned the sample of 100 healthy children and 100 children with developmental motor disorders from that documentation from years 1977–2006. The highest sensitivity showed the test of Vojta lateral tilt: 81%. Test of horizontal line of Collis showed sensitivity of 74%, test of vertical line of Collis showed 68%, Peiper-Isbertʼs test showed 51%, traction test showed 48%, armpitʼs hanging position test showed 31% and Landauʼs test showed 21%. The highest specificity showed the traction test (93%) and the Peiper-Isbertʼs test (93%), then the Landauʼs test and the armpitʼs hanging position test showed specificity of 91%, the test of Vojta lateral tilt showed 89%, the test of horizontal line of Collis showed 89% and the test of vertical line of Collis showed 88%. On account of evidenced high specificity and sensitivity of the tests of posture reactions and high efficiency of Vojta therapy and being aware of the fact that the efficiency is the higher the earlier the therapy is started, we propose to consider as suggestion that the pediatricion should learn to use besides the traditional examinated traction test of Prechtl also the two most sensitive tests (Vojta lateral tilt and test of horizontal line of Collis). In this case he would be able to recognize the child in danger earlier and more distinctly and the child could be send to the specialized departement in time.
