BACKGROUND
The existence of the transverse metatarsal arch (TMA) of the foot is a point of controversy. According to Kapandji, TMA of the foot elevates the 2(nd) to 4(th) metatarsal heads. Some authors suggest the existence of TMA, while others suggest that there is no functional metatarsal arch of the foot. In this study, we evaluated the existence of TMA of the foot and weight distribution on the metatarsal heads with the EMED-SF (Novel H, Munich, Germany) plantar pressure analysis system.
METHODS
The test was performed with 16 volunteers. According to the three functional columns of the foot, the metatarsal region of pressure picture obtained from the EMED-SF system was divided into three regions called 'masks'. Mean pressures in the masks were calculated at the mid-stance phase.
RESULTS
The highest mean pressure recorded was located at the 2nd to 3rd metatarsal heads (7.96 N/cm(2)), and the second highest pressure was at the heel (6.55 N/cm(2)). The pressures of the 1st metatarsal and 4th-5th metatarsal heads were 4.86 and 6.26 N/cm(2), respectively. The difference between the pressure distributions under metatarsal heads was statistically significant ( p=0.000).
CONCLUSION
According to our results, TMA of the foot does not exist as described by Kapandji.
背景
足横弓（TMA）的存在是一个有争议的问题。根据卡潘迪的说法，足横弓抬高第2至第4跖骨头。一些作者认为存在足横弓，而另一些作者则认为不存在功能性足横弓。在本研究中，我们使用EMED-SF（德国慕尼黑Novel H公司）足底压力分析系统评估了足横弓的存在以及跖骨头的重量分布。
方法
对16名志愿者进行测试。根据足的三个功能柱，将从EMED-SF系统获得的压力图像的跖骨区域分为三个称为“掩码”的区域。在站立中期计算掩码中的平均压力。
结果
记录到的最高平均压力位于第2至第3跖骨头（7.96 N/cm²），第二高压力位于足跟（6.55 N/cm²）。第1跖骨头和第4至第5跖骨头的压力分别为4.86和6.26 N/cm²。跖骨头下压力分布的差异具有统计学意义（p = 0.000）。
结论
根据我们的结果，足横弓并非如卡潘迪所描述的那样存在。
