[A new measuring device for computer-assisted imaging of the form and flexibility of the spine].

Our aim is to present a new method to examine spinal mobility and spine shape excluding torsional scoliosis. In comparison to measuring devices of the spine used so far, this noninvasive and easy to use method documents altered patterns of intervertebral mobility of the lumbar and thoracic spine. This may lead to a broader application of the triflexometer as a diagnostic tool for orthopedic and rheumatologic diseases that can decrease the frequency of X-ray exposure if used in combination with radiographs. In the present investigation the triflexometer demonstrates a good reproducibility of the triflexometer-based measurements. These findings support the ability of the triflexometer to depict disease courses of spinal disorders as well as the effect of therapy and rehabilitation.
