Comparison of Parameters of Spinal Curves in the Sagittal Plane Measured by Photogrammetry and Inclinometry
Journal Title: Ortopedia Traumatologia Rehabilitacja - Year 2013, Vol 15, Issue 5
Abstract
Background. The photogrammetric method and inclinometer-based measurements are commonly employed to assess the anteroposterior curvatures of the spine. These methods are used both in clinical trials and for screening purposes. The aim of the study was to compare the parameters used to characterise the anteroposterior spinal curvatures as measured by photogrammetry and inclinometry. Material and methods. The study enrolled 341 subjects: 169 girls and 172 boys, aged 4 to 9 years, from kinder-gartens and primary schools in Rzeszów. The anteroposterior spinal curvatures were examined by photogrammetry and with a mechanical inclinometer. Results. There were significant differences in the α angle between the inclinometric and photogrammetric assessment in the Student t test (p=0.017) and the Fisher Snedecor test (p=0.0001), with similar differences in the β angle (Student’s t p=0.0001, Fisher Snedecor p=0.007). For the γ angle, significant differences were revealed with Student’s t test (p=0.0001), but not with the Fisher Snedecor test (p = 0.22). Conclusions. 1. Measurements of inclination of particular seg ments of the spine obtained with the photogram-metric method and the inclinometric method in the same study group revealed statistically sig nificant differences. 2. The results of measurements obtained by photo grammetry and inclinometry are not comparable. 3. Further research on agreement between measu re ments of the anteroposterior spinal curvatures ob tained using the available measurement equip ment is recommended.
