我们研究了治疗师之间的信度和有效性的四个仪器在测量腰椎弯曲和骨盆倾斜。四种仪器及其测量方法为：1）皮尺测量躯干屈曲时腰椎曲度的变化; 2）重力测角器测量站立、躯干屈曲和躯干伸展时骨盆角和腰椎曲度; 3）重力测角器测量站立、躯干屈曲和躯干伸展时腰椎曲度;和4）标准测角器，用于测量垂直于脊柱安装的木制指针之间的角度，以获得站立、躯干屈曲和躯干伸展期间的骨盆角和腰椎弯曲。我们发现没有一个单一的工具是最可靠或有效的。治疗师之间的可靠性范围为0.64至0.93（皮尔逊积差相关）和0.60至0.92（组间相关系数）。与X光片测量值相比，这些仪器的有效性通常较低，范围为-0.13至0.76（皮尔逊积差相关）和-0.73至0.05（组间相关系数）。
We studied the between-therapist reliability and the validity of four instruments in measuring lumbar spine curvature and pelvic tilt. The four instruments and their measurements were 1) a tape measure to measure the change in lumbar curvature during trunk flexion; 2) a gravity goniometer to measure pelvic angle and lumbar curvature during stance, trunk flexion, and trunk extension; 3) a parallelogram goniometer to measure lumbar curvature during stance, trunk flexion, and trunk extension; and 4) a standard goniometer to measure the angle between wooden pointers mounted perpendicularly to the spine to obtain pelvic angle and lumbar curvature during stance, trunk flexion, and trunk extension. We found no single instrument to be the most reliable or valid. Between-therapist reliability ranged from .64 to .93 (Pearson product-moment correlation) and from .60 to .92 (interclass correlation coefficient). The validities of the instruments compared with measurements from roentgenograms generally were low, ranging from −.13 to .76 (Pearson product-moment correlation) and −.73 to −.05 (interclass correlation coefficient).
