In a prospective randomized study involving 30 gravidae with breech presentation the efficacy of a maternal positioning exercise--raising of the pelvis, abduction of the thighs, relaxed abdominal breathing--for the purpose of spontaneous version of the fetus into vertex presentation was investigated. The results were compared with the rate of uninfluenced, spontaneous version in a further 31 gravidae with the same initial conditions. In view of the low numbers involved no statistical statements can be made; however, version in 21 out of 30 positioned subjects (70%) as opposed to 17 out of 31 spontaneous versions indicates some degree of success. Considering the risks of breech presentation during pregnancy and at birth on the one hand and the absence of risk and good acceptance of the positioning exercise on the other, the method can be recommended.
在一项涉及30例臀位孕妇的前瞻性随机研究中，对一种孕妇体位锻炼方法——抬高骨盆、外展大腿、放松腹部呼吸——促使胎儿自然转为头先露的效果进行了研究。将结果与另外31例初始条件相同、未受干预自然转位的孕妇的转位率进行了比较。鉴于研究样本数量较少，无法进行统计学分析；然而，30例接受体位锻炼的孕妇中有21例（70%）转位，而31例自然转位的孕妇中有17例转位，这表明该方法有一定程度的成功。考虑到一方面臀位妊娠和分娩期间存在风险，另一方面体位锻炼没有风险且易于接受，该方法值得推荐。
