In our clinical study, the stages of pregnancy were independent variables, and the measured change of sensitivity in selected skin areas was the dependent variable. The research hypothesis that the threshold electric skin sensitivity (TESS) fluctuates was based on our previously published research, where the null hypothesis was rejected in similar conditions. TESS was measured repeatedly in short intervals on the abdomen and right forearm of pregnant and not pregnant women. A statistically very significant change of TESS fluctuation was found between not pregnant and pregnant women in different stages of pregnancy, labor, and postpartum. In the midline above the navel, the TESS fluctuates with similar frequency like intestinal peristalsis and that may reflect on the functional state of the bowels. In both lateral areas of the lower abdomen in not pregnant women and in early pregnancy, we found only minimal TESS fluctuations. They gradually increased until the beginning of labor and then decreased postpartum. In midline above the pubic symphysis, moderate TESS fluctuation in not pregnant women gradually increased during pregnancy, until the beginning of labor and decreased postpartum. TESS fluctuation during labor was not synchronous with recorded uterine contractions. Only minimal TESS fluctuation on the right forearm never changed significantly. TESS fluctuation in midline abdomen may be related to bowel peristaltic motility. In the lateral abdomen and above symphysis, it may be related to uterus activity. TESS measurement in referral pain skin area could be used for functional monitoring of internal organ in the corresponding viscerotome. The measurement of TESS in skin areas and recording fluctuations graphically as an electrosensitogram, could have diagnostic value. As a new noninvasive diagnostic method, electrosensitography could help us better understand the gastrointestinal organ function.
在我们的临床研究中，妊娠阶段是自变量，所选皮肤区域敏感性的测量变化是因变量。关于阈值皮肤电敏感性（TESS）波动的研究假设基于我们之前发表的研究，在类似条件下原假设被拒绝。在孕妇和非孕妇的腹部和右前臂上，短时间间隔内反复测量TESS。在非孕妇与处于妊娠、分娩和产后不同阶段的孕妇之间，发现TESS波动存在统计学上非常显著的变化。在肚脐上方的中线处，TESS的波动频率与肠道蠕动相似，这可能反映了肠道的功能状态。在非孕妇和孕早期孕妇的下腹部两侧区域，我们仅发现TESS有极小的波动。这些波动逐渐增加，直至分娩开始，然后在产后下降。在耻骨联合上方的中线处，非孕妇的TESS适度波动在孕期逐渐增加，直至分娩开始，并在产后下降。分娩期间TESS的波动与记录的子宫收缩不同步。右前臂上只有极小的TESS波动从未有显著变化。腹部中线处的TESS波动可能与肠道蠕动有关。在下腹部两侧和耻骨联合上方，它可能与子宫活动有关。在牵涉痛皮肤区域测量TESS可用于相应体节中内脏器官的功能监测。在皮肤区域测量TESS并以电敏感图的形式记录波动情况可能具有诊断价值。作为一种新的非侵入性诊断方法，电敏感成像可帮助我们更好地了解胃肠器官功能。
