[The level of reliability of Lasegue's symptoms measured in the sitting position--results of a multicenter study].
The results of Lasègue test /LT/ examination are not always enough objective owing to subjective complaints superposition. The first favourable clinical experiences with analysis of the LT in sitting position stimulated our previous anatomical, biometrical and clinical investigations (Mandić and col. 1970.). There has been established the stretching of the ischial nerve in classical LT to 12.7 cm, in sitting position to 4.8 cm, and the changing of position from supine to sitting to 6.4 cm. That means that the stretching in sitting LT is greater then in classical way/i.e. 13.26 cm/. The stretching forces in both ways were equal (0-3.7 kp/. The multicentric investigation included 330 patients of both sexes, aged 15-62 years. In 57 patients/17.3%/was LT in sitting position positive and in supine negative. That demonstrate the higher degree of reliability 17.3%. These quantitative results will be continued in qualitative investigation of statistical correlation of relative flexion degrees. The advantages of sitting LT are:more simple, more quick, the taking off patient's clothes is not needed, and the result is more suitable for the objective evaluation of psychogenic complaints superposition or simulation.
