Reproducibility of Sagittal Pelvic Tilt Measurements in Normal Subjects Using Digital Inclinometry
Abstract
Standing sagittal pelvic tilt posture is widely assessed qualitatively, yet no efficient non-invasive quantitatively method is available for measuring pelvic tilt position or its amplitude. The main objective of the current study was to assess the intra- and inter-tester reproducibility of digital inclinometry-based (DI) measurements of pelvic tilt in healthy subjects. Pelvic inclination was measured while standing in neutral position (NP), maximal anterior pelvic tilt (APT) and maximal posterior pelvic tilt (PPT) which served for calculating the total pelvic tilt (TPT) range of motion (TPT=PPT-APT). On two separate test occasions two convenience samples of healthy women and men (N=15 in each) were each measured by two different testers. In both groups the intra-tester reproducibility indices of NP, APT, PPT and TPT were acceptable as revealed by high and significant ICCs and low standard error of measurements (SEM). In women the inter-tester reproducibility indices, of the same variables, were high as distinguished by no significant differences between testers and high and significant ICCs. In men, significant differences were found in APT and PPT but the between-testers TPT scores were similar. Collectively these findings indicate that pelvic inclinometry yields acceptable reproducibility which in the light of the facility of the method may render it an efficient clinical tool.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
