Objective To analyze the clinical effect of a bifurcated ball frame designed for undergraduate research to assist hand-knee position,avoid physical exertion and increase comfort.Methods Randomized controlled trials consisted of 260 occipital (posterior) primiparous women born during labor,and were randomly divided into the observation group and the control group with 130 cases each.The observing group's mothers were on the yoga ball on the device.The angle and height of the frame and the ball plate were adjusted according to the maternal body type,so that the yoga ball at the chest and the cross could effectively support the maternal weight loss knee burden,and both sides of the small abdominal yoga ball could be effectively posted.After the adjustment was completed,the maternal relaxes and gently shakes the body in one direction so that the small yoga ball on the ventral side forms a continuous soothing push.The control group leaned forward on both knees (with protective gear) and supported themselves with both hands or both fists,swaying the pelvis or crawling forward.Comparing the two groups of vaginal delivery rate,maternal postural maintenance time,maternal dehvery experience,and effective correction rate of occipital position.Results The time of postoperative maintenance in the observation group was (49.51 ±10.62) minutes,and that of the control group was (18.31 ± 9.72) minutes.The difference between the two groups was statistically significant (t=6.69,P ＜0.05).The effective correction of abnormal fetal position rate,spontaneous delivery rate and comfort rate were 82.30％ (107/130),77.69％ (101/130),and 99.23％ (129/130),respectively in the observation group,and 27.69％ (36/130),33.85％ (44/130),3.84％ (5/130),respectively in the control group,the differences between the two groups were statistically significant (x2 =4.06,4.15,5.61,all P ＜0.05).Conclusions The undergraduate design of this sort of ball delivery group has a significant effect on the extraversion of the assisted position to the fetal position.
