摘要:


文题释义:

拍摄测量法:是一种通过拍摄图像或视频来进行测量和分析的方法。它通常用于医学、工程、科学研究等领域,用于获取物体的尺寸、形状、角度等信息。通过拍摄图像或视频,可以使用计算机软件进行测量和分析,从而得出所需的数据和结论。拍摄测量法可以提供非接触式的测量方式,具有快速、准确、方便等优点,被广泛应用于各个领域。
骨盆姿势:是指骨盆在立位或坐位时的位置和倾斜角度。骨盆姿势通常包括前后倾、左右倾等方面的变化。前后倾是指骨盆在前后方向上的倾斜程度,正常情况下应该保持适度的前倾。左右倾是指骨盆在左右方向上的倾斜程度,正常情况下应该保持平衡。不正确的骨盆姿势可能导致身体姿态的不稳定,造成肌肉不平衡、脊柱曲度异常、运动功能障碍等问题。因此,保持正确的骨盆姿势对于维持身体健康和预防运动损伤非常重要。


背景:在临床中通常使用触诊方法定位髂前上棘、髂后上棘,通过目测观察法或拍摄测量法来确定骨盆的倾斜情况。其中目测观察法只能有定性的结论,且其信度较差;而拍摄测量法不仅更方便、快捷,还能给出较精确的定量数据,是最佳的临床评估方法之一。但是国内尚无针对使用拍摄测量法评估骨盆姿势的信度研究。

目的:采用目测观察法和拍摄测量法对骨盆姿势进行评估,比较两种方法的信度水平以指导临床应用。
方法:选择45例健康受试者,在双侧髂前上棘及髂后上棘处作红色标记,从受试者前面、后面(额状面)、左面、右面(矢状面)进行骨盆姿势的拍照。从前面观、后面观选取骨盆左右倾角(ɑ、β角),即双侧髂前上棘连线或双侧髂后上棘连线与水平线的夹角;从侧面观选取骨盆前后倾角(γ、θ角),即同侧髂前上棘和髂后上棘连线与水平面的夹角,表示矢状面骨盆前后倾的情况。评估方法包括目测观察法和拍摄测量法,2位评估者进行独立评估,先使用目测观察法记录骨盆α、β、γ、θ角,再使用拍摄测量法记录骨盆α、β、γ、θ角。间隔1个月后再次进行目测观察法和拍摄测量法,分别记录骨盆α、β、γ、θ角。采用相关系数分析2种评估方法及前后测量所得数据,0.90-0.99为相关性优秀,0.80-0.89为相关性良好,0.70-0.79为相关性中度,≤0.69为相关性较差;并且通过计算得到测量标准误及最小可检测变化值以评价评估者间和评估者内部信度。 

结果与结论:①评估者内部相关系数,目测观察法和拍摄测量法的相关系数:前面观为0.682和0.718,后面观为0.513和0.867,左面观为0.739和0.960,右面观为0.756和0.971;目测观察法前面观和后面观的相关性较差,左面和右面观的相关性为中度;拍摄测量法前面观的相关性为中度,后面观的相关性良好,左面和右面观的相关性均为优秀。测量标准误方面:前面观为3.266和1.625,后面观为4.278和1.763,左面观为5.935和1.787,右面观为5.723和1.698。最小可检测变化值方面:前面观为9.053和4.504,后面观为11.858和4.887,左面观为16.451和4.953,右面观为15.863和4.707。②评估者间相关系数,目测观察法和拍摄测量法的相关系数:前面观为0.452和0.723,后面观为0.483和0.904,左面观为0.518和0.955,右面观为0.657和0.968;目测观察法4个方向的的相关性均较差;拍摄测量法除前面观的相关性为中度,其他3个方面的相关性均位优秀。测量标准误方面:前面观为5.651和1.610;后面观为4.237和1.523;左面观为7.322和1.891;右面观为6.509和1.781。最小可检测变化值方面:前面观为15.664和4.463;后面观为11.744和4.222;左面观为20.296和5.242;右面观为18.042和4.937。③结果证实拍摄测量法评估矢状面、额状面骨盆姿势的评估者内部、评估者间信度均很好,尤其是通过拍摄测量法的数据稳定性较好;该方法简单、快捷、高效、准确、成本低廉、无X射线损害,能定性、定量地反映出患者骨盆的实际情况,适合在临床中推广使用。

Abstract: BACKGROUND: In clinical practice, the anterior superior iliac spine and posterior superior iliac spine are usually located by palpation, and the tilt of the pelvis is determined by visual observation method or photogrammetry. Among them, the visual observation method can only have qualitative conclusions, and its reliability is poor. The photogrammetry is not only more convenient and fast, but also can give more accurate quantitative data, which is one of the best clinical evaluation methods. However, there are no studies on the reliability of pelvic posture assessment using photogrammetry in China. 
OBJECTIVE: To evaluate the pelvic posture by visual observation method and photogrammetry, and to compare the reliability level of the two methods to guide clinical application. 
METHODS: Forty-five healthy subjects were selected and red marks were made at the bilateral anterior superior iliac spine and posterior superior iliac spine. Pelvic posture was photographed from the front, back (coronal plane), left, and right (sagittal plane). The left and right pelvic tilt angles (α, β angles) were selected from the front and back views, which represented the angle between the bilateral anterior superior iliac spine line or the bilateral posterior superior iliac spine line and the horizontal line. The anterior and posterior pelvic tilt angles (γ, θ angles) were selected from the side view, which represented the angle between the ipsilateral anterior superior iliac spine and posterior superior iliac spine line and the horizontal plane, indicating the sagittal plane pelvic tilt. Evaluation methods included visual observation method and photogrammetry. Two evaluators independently evaluated the pelvic α, β, γ, θ angles using the visual observation method first, and then recorded the pelvic α, β, γ, θ angles using the photogrammetry. After a one-month interval, the visual observation method and photogrammetry were performed again, and the pelvic α, β, γ, θ angles were recorded. The intraclass correlation coefficients were used to analyze the data obtained from the two evaluation methods and the before-and-after measurements: 0.90-0.99 as an excellent correlation, 0.80-0.89 as a good correlation, 0.70-0.79 as a moderate correlation, and ≤0.69 as a poor correlation. The standard error of measurement and the minimal detectable change with 95% confidence intervals were calculated to evaluate the inter-rater and intra-rater reliability. 
RESULTS AND CONCLUSION: (1) The interrater intraclass correlation coefficients of the visual observation method and photogrammetry were as follows: anterior view: 0.682 and 0.718, posterior view: 0.513 and 0.867, left view: 0.739 and 0.960, and right view: 0.756 and 0.971. The visual observation method showed poor correlation between the anterior and posterior views and moderate correlation between the left and right views, while the photogrammetry showed moderate correlation for the anterior view, good correlation for the posterior view, and excellent correlation for the left and right views. The standard error values of measurement were as follows: anterior view: 3.266 and 1.625, posterior view: 4.278 and 1.763, left view: 5.935 and 1.787, and right view: 5.723 and 1.698. The minimal detectable change values with 95% confidence intervals were as follows: anterior view: 9.053 and 4.504, posterior view: 11.858 and 4.887, left view: 16.451 and 4.953, and right view: 15.863 and 4.707. (2) The interrater intraclass correlation coefficients of the visual observation method and photogrammetry were as follows: anterior view: 0.452 and 0.723, posterior view: 0.483 and 0.904, left view: 0.518 and 0.955, and right view: 0.657 and 0.968. The visual observation method showed poor correlation in all four directions, while the photogrammetry showed moderate correlation for the anterior view and excellent correlation for the other three directions. The standard error values of measurement were as follows: anterior view: 5.651 and 1.610, posterior view: 4.237 and 1.523, left view: 7.322 and 1.891, and right view: 6.509 and 1.781. The minimal detectable change values with 95% confidence intervals were as follows: anterior view: 15.664 and 4.463, posterior view: 11.744 and 4.222, left view: 20.296 and 5.242, and right view: 18.042 and 4.937. (3) These results confirm that the sagittal and coronal plane photogrammetries have good intrarater and interrater reliability for evaluating pelvic posture, especially with the use of the photogrammetry, which has good data stability. This method is simple, fast, efficient, accurate, low-cost, and does not cause X-ray damage, and can qualitatively and quantitatively reflect the actual situation of the patient’s pelvis, making it suitable for clinical use.
