骨盆倾斜度测量仪的可靠性及实用价值的观察研究

作者以自己设计制作的“骨盆倾斜度测量仪”对126例生育年龄非妊娠妇女进行骨盆倾斜度体测量与X线测量;计算两种方法所获数值的相关系数,相关系数r=0.85,具高度量著性:推出以活体测量数值推算骨盆真实倾斜度的回归方程:y=1.3567x-3.6132±0.1435,=9.45,P<0.0005,有高度显著性,证明骨盆倾斜度测量仪及上述回归方程准确、可靠,方法简便、实用,值得推广,足以取代X线测量法。

The study on the reliability and practicability of the measuringinstrumen: of inclination of pelvis

The anthropometry with the measuring instrument created by the authorsand the radiogrammetry of the inclination of pelvis have been carriedout in 126 women, who are at childbearing age and not fertilized. The correlation coefficient between the values obtained by the abovetwo methods has been figured out, the correlation coefficient is, highly significant (r=0.85). The regression equation to evaluate the inclination of pelvis with the values ob- tained by the anthropometry has been calculated, i.e.(?)=1.3567x-3.6132 ±0.1435,t_b=9.455, P=0.0005. It is or great significance. It confirms that the instrument and the regressiion equation are accurate and reliable, and the methodis simple and practical. They are promotionable and can relpace the radiogrammetry.
