The purpose of this study was to examine intratester reliability of a test designed to measure the standing pelvic-tilt angle, active posterior and anterior pelvic-tilt angles and ranges of motion, and the total pelvic-tilt range of motion (ROM). After an instruction session, the pelvic-tilt angles of the right side of 20 men were calculated using trigonometric functions. Ranges of motion were determined from the pelvic-tilt angles. Intratester reliability coefficients (Pearson r) for test and retest measurements were .88 for the standing pelvic-tilt angle, .88 for the posterior pelvic-tilt angle, .92 for the anterior pelvic-tilt angle, .62 for the posterior pelvic-tilt ROM, .92 for the anterior pelvic-tilt ROM, and .87 for the total ROM. We discuss the factors that may have influenced the reliability of the measurements and the clinical implications and limitations of the test. We suggest additional research to examine intratester reliability of measuring the posterior pelvic-tilt ROM, intertester reliability of measuring all angles and ROM, and the pelvic tilt of many types of subjects.
本研究的目的是检验一项旨在测量站立位骨盆倾斜角度、主动后倾和前倾骨盆倾斜角度及活动范围，以及骨盆倾斜总活动范围（ROM）的测试在测试者内部的可靠性。在一次指导课程后，使用三角函数计算了20名男性右侧的骨盆倾斜角度。活动范围由骨盆倾斜角度确定。测试和重新测试测量的测试者内部可靠性系数（Pearson r），站立位骨盆倾斜角度为0.88，后倾骨盆倾斜角度为0.88，前倾骨盆倾斜角度为0.92，后倾骨盆倾斜ROM为0.62，前倾骨盆倾斜ROM为0.92，总ROM为0.87。我们讨论了可能影响测量可靠性的因素以及该测试的临床意义和局限性。我们建议进行更多研究，以检验测量后倾骨盆倾斜ROM的测试者内部可靠性、测量所有角度和ROM的测试者间可靠性，以及多种类型受试者的骨盆倾斜情况。
