OBJECTIVE The aim of this study is to determine correlations between the parameters of body posture in the sagittal profile and sagittal jaw position by obtaining objective and valid three-dimensional measurements of the dorsal profile by means of rasterstereography. MATERIALS AND METHODS Fifty-three adults with Class II or III malocclusions were(More)
BACKGROUND Back surface topography has gained acceptance in recent decades. At the same time, the motivation to use this technique has increased. From the view of the patient, the cosmetic aspect has played and still plays a major role as it provides a comprehensive documentation of cosmetic impairment. From the view of the medical practitioner, the aspect(More)
Video rasterstereography is a method for back surface measurement comprising automatic back surface reconstruction and shape analysis. It is particularly appropriate for the examination of scoliosis. In this application shape analysis includes model-based calculations of vertebral rotation (determined from surface rotation) and of the spinal midline in(More)
QUESTION Video rasterstereography is a method for back surface measurement comprising automatic back surface reconstruction and shape analysis. Aim of this prospective study was to determine the accuracy of this method in comparison to the conventional frontal and lateral standing radiographs. METHOD 95 patients with idiopathic scoliosis or scoliotic(More)
BACKGROUND Protection of the foot may necessitate reduction of peak pressures in specific plantar regions. The study focuses on the unloading effects that exercising step-to gait may have. METHODS 20 healthy volunteers were recruited and completed three pedobarographic examinations measuring peak pressures in different gait patterns: normal, half-step(More)
A method for automatic measurement of anatomical landmarks on the back surface is presented. The landmarks correspond to the verteba prominens, the dimples of the posterior superior iliac spines and the sacrum point (beginning of rima ani), which are characterized by distinct surface curvature. The surface curvatures are calculated from rasterstereographic(More)
OBJECTIVE To analyze the correlation ratios between the spinal posture (thoracic, lordotic, and pelvic inclination) and the craniofacial morphology. MATERIALS AND METHODS The sample consisted of 53 healthy adults (32 women, 21 men; mean age 24.6 years). Six angular skeletal measurements (facial axis, mandibular plane angle, inner gonial angle, lower(More)
Measurement of vertebral rotation from frontal X-ray projections of the pedicles was introduced by Nash and Moe. By the introduction of a vertebral model, their method and different modifications can be described and characterized easily. A geometrical analysis shows, that two parameters are sufficient for this model. When applying an appropriate(More)
Anatomical landmarks on the body surface can be measured with high accuracy by using rasterstereography and surface curvature analysis. The present study shows that the lumbar dimples can be localized with a statistical error of about 1 mm. It is generally assumed that the dimples are in close relation to the pelvis (in particular to the PSISs) and may thus(More)
