简要总结
This study aims to investigate the short-term modifications in head and neck positioning by usage of low-powered prismatic lenses in patients with Postural Deficiency Syndrome (PDS). A matched pair observation study was designed. Evaluation is carried out using low dose biplanar radiography before treatment and 15 minutes after lenses application.

结局指标
主要结局
Radiographic modification of pelvic tilt angle
时间窗: From enrollment to second radiographic evaluation on day 1
Changes in pelvic tilt angle are measured between two subsequent radiographic biplanar scans in standing position, before and after lenses application on the same patient. Measurement is performed in degrees using the radiographic equipment proprietary software (EOS imaging). A minimum clinical significance value of 3 degrees was estimated.
Radiographic modification of C0 inclination
时间窗: From enrollment to second radiographic evaluation at day 1
Changes in C0 inclination angle are measured between two subsequent radiographic biplanar scans in standing position, before and after lenses application on the same patient. Measurement is performed in degrees using the radiographic equipment proprietary software (EOS imaging). A minimum clinical significance value of 3 degrees was estimated.
Radiographic modification of cervical spinal vertical alignment
时间窗: From enrollment to second radiographic evaluation at day 1
Changes of cervical spinal vertical alignment are measured between two subsequent radiographic biplanar scans in standing position, before and after lenses application on the same patient. Measurement is performed in millimeters using the radiographic equipment proprietary software (EOS imaging). A minimum clinical significance value of 2 millimeters was estimated.
次要结局
- Radiographic modification of cervical lordosis(From enrollment to second radiographic evaluation at day 1)
- Radiographic modification of inclination of C1(From enrollment to second radiographic evaluation at day 1)
- Radiographic modification of inclination of C2(From enrollment to second radiographic evaluation at day 1)
- Radiographic modification of global spinal vertical alignment(From enrollment to second radiographic evaluation at day 1)
