Postural Disorders, Postural Imbalance, Postural Neck Pain
Conditions
Brief summary
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.
Interventions
DEVICEPrismatic low-powered lenses
Participants perform biplanar X-ray before and after lens application

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Radiographic modification of pelvic tilt angle | 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 | 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 | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Radiographic modification of cervical lordosis | From enrollment to second radiographic evaluation at day 1 | Changes of cervical lordosis 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). |
| Radiographic modification of inclination of C1 | From enrollment to second radiographic evaluation at day 1 | Changes of C1 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). |
| Radiographic modification of inclination of C2 | From enrollment to second radiographic evaluation at day 1 | Changes of C2 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). |
| Radiographic modification of global spinal vertical alignment | From enrollment to second radiographic evaluation at day 1 | Changes of global 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). |
