1. The proposed hypothesis was that 'the score of labor pain could be lower in the group which had LI-4 pressure applied than in the control group'.

The proposed hypothesis was that 'the score of duration of delivery time could be shorter in the group which had LI-4 pressure applied than in the control group'. The design of this study was a nonequivalent control group non-synchronized post test only design to verify the effect on labor pain for primipara women treated by LI-4 pressure and to evaluate the benefits of using LI-4 pressure on some women and judging the degree of their labor pains in comparison with other primipara women not treated with LI-4 pressure. The subjects included 63 primipara women who underwent vaginal delivery, who were between 38-41 weeks intra uterine pregnancy; who did not have any complications; and who were under pitocin augmentation or induction. They were recruited with informed consent; 34 were in the control group and 29 were in the experimental group. The study was measured with a structured questionnaire consisting of general characteristics, knowledge related to delivery, subjective (Johnson, 1974) and objective(McLachlan, 1974) labor pain scale, data collection was done by research during the period from April, 2000 to July, 2000 and data was analyzed by descriptive statistics, χ²-test, and t-test. The results were as follows: 1. The scores of total labor pain in the group which had LI-4 pressure applied were lower(347.62±49.84) than in the group(411.02±55.79) which did not have LI-4 pressure applied; And these differences were statistically significant(t=4.7193, p=.000).

The duration of delivery time in the group which had LI-4 pressure applied was shorter (390.51min±111.91) than in the group (460.44min±190.78)which did not have LI-4 pressure applied and the duration of delivery time in the experimental group was statistically more significant than that in the control group. therefore this thesis was adapted(t=1.734, p=.0879).
