This research was conducted in a public general hospital in Mexico City, Mexico. The objective was to evaluate efficacy of the support given by a doula during labor to reduce cesarean rate. From March 1997 to February 1998, a group of 100 pregnant women were studied. These women were at term, engaged in an active phase of labor, exhibited 3 cm. or more cervical dilatation, were nuliparous, had no previous uterine incision, and possessed adequate pelvises. The group was randomly divided into two subgroups comprising 50 women, each: The first subgroup had the support of a childbirth educator trained as a doula, while the second subgroup did not have doula support. Measurements were recorded on the duration of labor, the use of pitocin, and whether or not the birth was a vaginal birth or cesarean section. Characteristics and gestational age were similar in both groups. Results confirmed that support by doulas during labor was associated with a significant reduction in cesarean birth and pitocin administration. There was a trend toward shorter labors and less use of epidurals. The results of this study showed, as in other trials measuring the impact of a doula's presence during labor and birth, that doula support during labor is associated with positive outcomes that have physical, emotional, and economic implications. 相似文献

The purpose of the study was to compare core muscle activation of the tradition prone plank with a modified version performed with a long-lever and posterior-tilt using surface electromyography. To further determine if a specific component of this modified plank was more effective than the other in enhancing muscle activity, the plank with a long lever and the plank with a posterior pelvic tilt were studied individually. Nineteen participants performed all four variations of the plank for 30 seconds in a randomized order with 5-minute rest between exercise bouts. Compared to the traditional prone plank, the long-lever posterior-tilt plank displayed a significantly increased activation of the upper rectus abdominis (p < 0.001), lower abdominal stabilizers (p < 0.001), and external oblique (p < 0.001). The long-lever plank showed significantly greater activity compared to the traditional plank in the upper rectus abdominis (p = 0.015) and lower abdominal stabilizers (p < 0.001), while the posterior tilt plank elicited greater activity in the external oblique (p = 0.028). In conclusion, the long-lever posterior-tilt plank significantly increases muscle activation compared to the traditional prone plank. The long-lever component tends to contribute more to these differences than the posterior-tilt component. 相似文献
