Comparison of the kyphosis angle evaluated by video rasterstereography (VRS) with x-ray measurements.

Unlabelled: Surface topography evaluations are prone to technical errors due to postural sway of the patients measured. The technical error of lateral deviation (rms) and surface rotation (rms) may vary between 15 and 20%, while the kyphosis angle (IP-ITL) has a technical error of only 5% (2,5 degrees), which is comparable to the x-ray measurement. Purpose of this study was to investigate the hypothesis that video rasterstereography can be used for prognostication of a kyphosis patient.

Preliminary results and worst-case analysis of in patient scoliosis rehabilitation.

The purpose of this study was to assess the effectiveness of a scoliosis-specific rehabilitation programme as it is carried out in the Katharina Schroth Spinal Deformities Rehabilitation Center. Physiotherapy in the treatment of scoliosis patients is still regarded as ineffective since the study by the American Orthopedic Association in 1941, which showed that general exercises could not influence the natural history of scoliosis. However, specific exercise programmes were not known in the USA at that time.
