Abstract

The purpose of this study was to determine the reliability of a computer software angle tool that measures thoracic (T), lumbar (L), and pelvic (P) angles as a means of evaluating spine and pelvic flexibility during the sit-and-reach (SR) test. Thirty adults performed the SR twice on separate days. The SR test was captured on video and later analyzed for T, L, and P angles using the computer software angle tool. During the test, 3 markers were placed over T1, T12, and L5 vertebrae to identify T, L, and P angles. Intraclass correlation coefficient (ICC) indicated a very high internal consistency (between trials) for T, L, and P angles (0.95-0.99); thus, the average of trials was used for test-retest (between days) reliability. Mean (±SD) values did not differ between days for T (51.0 ± 14.3 vs. 52.3 ± 16.2°), L (23.9 ± 7.1 vs. 23.0 ± 6.9°), or P (98.4 ± 15.6 vs. 98.3 ± 14.7°) angles. Test-retest reliability (ICC) was high for T (0.96) and P (0.97) angles and moderate for L angle (0.84). Both intrarater and interrater reliabilities were high for T (0.95, 0.94) and P (0.97, 0.97) angles and moderate for L angle (0.87, 0.82). Thus, the computer software angle tool is a highly objective method for assessing spine and pelvic flexibility during a video-captured SR test.

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.
