A rise in plantar pressure has been observed in pregnant women with foot pain. The current literature on plantar pressure in pregnancy is sparse. It has been postulated that changes in plantar pressure result from the physiological effects of pregnancy. In this study we aim to quantify the plantar pressure of women in late pregnancy.
Twenty-two pregnant women undergoing a caesarean section and twenty non-pregnant women were recruited from University Hospital Coventry and Warwickshire between May to June 2007. Plantar pressure measurements were performed using an in-shoe measurement system. The control group was compared with the pregnant group at 38 weeks gestation. A selection of the pregnant group had repeat measurements at 4 months post-partum. The pre and post-partum measurements were also compared.
The pregnant group (PG) exerted a significantly higher mean midfoot pressure compared to the non-pregnant control group (CG) (PG=115.5kPa, CG=95.4kPa; p=0.001). Post-partum (PP), there was a significant reduction in the mean and maximum midfoot pressure (mean; PG=111.9kPa, PP=66.2kPa; p<0.001, maximum; PG=184.0kPa, PP=108.3kPa; p<0.001).
The physiological changes in late pregnancy result in an increase in midfoot plantar pressure. This increase resolves post-partum.
在有足部疼痛的孕妇中观察到足底压力升高。目前关于孕期足底压力的文献较少。据推测，足底压力的变化是由怀孕的生理影响导致的。在本研究中，我们旨在量化妊娠晚期女性的足底压力。
2007年5月至6月期间，从考文垂大学医院和沃里克郡大学医院招募了22名接受剖宫产的孕妇和20名非孕妇。使用鞋内测量系统进行足底压力测量。将对照组与妊娠38周时的孕妇组进行比较。部分孕妇组在产后4个月进行了重复测量。还比较了产前和产后的测量结果。
与非妊娠对照组（CG）相比，孕妇组（PG）的平均足中部压力显著更高（PG = 115.5kPa，CG = 95.4kPa；p = 0.001）。产后（PP），足中部的平均压力和最大压力均显著降低（平均；PG = 111.9kPa，PP = 66.2kPa；p < 0.001，最大；PG = 184.0kPa，PP = 108.3kPa；p < 0.001）。
妊娠晚期的生理变化导致足中部足底压力增加。这种增加在产后消退。
