Evaluation and measurement of expert midwives motion during conduct labor

本研究拟开发一种劳动模拟器，作为基础研究的学习工具。研究了学生和专家在劳动过程中运动的差异。采用压敏导电墨水压力传感器测量了顺产过程中手指和手掌的压力。我们测量了13名学生和17名专家在劳动过程中的压力。然后根据压力传感器和运动图像的检测结果提取运动专家的特征。专家平均压力高于学生平均压力，且专家在指导劳动过程中存在较大的差异。计算枕外隆凸娩出时左右手压力分布的相关系数。发现最佳的分娩方式是正面体位法，因为正面体位法在分娩过程中右手与上举手的同步率最高。

This study planned to develop a labor simulator for learning tool on basic research. The differences of the motion during the conduct of labor between students and experts were examined. The pressure sensor using pressure sensitive conductive ink was used to measure the pressure of the finger and the palm during the conduct labor. We measured the pressure during the conduct of labor on 13 students and 17 experts. Then the characteristic of the motion experts were extracted by the results from pressure sensor and motion picture. Expert mean pressure are higher than student ones and in addition the large variation of expert were showed during the conduct labor. The correlation coefficients between the pressure profiles of right hand and left hands during the delivery of the external occipital protuberance were calculated. It is founds that the best conduct labor method is frontage position method because It is the highest rate of synchronizing between right hand and lift hand during the conduct of labor.
