[Stretching--do current explanatory models suffice?].
The opinion that mobility in the usual performance if the "straight leg raise" test for the evaluation of stretching techniques is subject to solety muscular limitations is critically appraised. With integration of recent results from molecular biological research and our own measurements, we can show that not only mechanical but also neurophysiological factors must be considered in the limitation of mobility. In the majority of the examined patients stretching of the ischiadic nerve seems to be responsible for restrictions in movement. The presented results cast doubt on the currently held assumptions and basic principles of stretching in therapy and sport.
