The effect of maternal position on fundal height measurements was studied in 192 nonobese women between 21 and 36 weeks of gestation. Four clinicians participated in the study and each clinician obtained measurements on 48 women. Fundal height measurements were obtained in each of four positions: supine; trunk elevation; knee flexion; and trunk elevation with knee flexion. The sequence in which measurements were obtained was assigned randomly. Clinicians were blinded to the results of their measurements. Measurements obtained in the supine position were largest, and measurements obtained in the trunk elevation with knee flexion position were smallest. Repeated measures analysis of variance demonstrated that measurements obtained in the four positions were significantly different (F = 87.71, df = 3,573, P < .001). A posteriori comparisons demonstrated that measurements obtained in each position were significantly different except for measurements obtained in the trunk elevation and knee flexion positions. These findings indicate that clinicians should be consistent when they position patients to obtain fundal height measurements.
在192名妊娠21至36周的非肥胖女性中研究了母亲体位对宫高测量的影响。四名临床医生参与了该研究，每位临床医生对48名女性进行测量。在四个体位下分别进行宫高测量：仰卧位；躯干抬高；屈膝；躯干抬高并屈膝。测量顺序随机分配。临床医生对其测量结果不知情。仰卧位测量值最大，躯干抬高并屈膝位测量值最小。重复测量方差分析表明，四个体位下的测量值有显著差异（F = 87.71，自由度 = 3,573，P < .001）。事后比较表明，除躯干抬高位和屈膝位的测量值外，每个体位下的测量值均有显著差异。这些发现表明，临床医生在为患者定位以进行宫高测量时应保持一致。
