Abstract：
BACKGROUND: the area beneath the metatarsal heads is a common location of foot pain, which is often associated with high plantar pressures. The aim of this study was to determine the effect of the application of a Morton\'s extension on the pressure in the metatarsal bones of the foot using a pressure platform.
METHODS: twenty-five subjects without musculoskeletal pathology were selected for this study, and an experiment was conducted with them as the subjects, before and after application of a Morton\'s extension. The foot regions were divided into the forefoot (transversely subdivided into six areas corresponding to the first, second, third, fourth, and fifth metatarsal heads, and the hallux), midfoot, and rearfoot, and then the maximum and average pressures exerted at each region were measured before and after placing a Morton\'s extension.
RESULTS: we found a pressure reduction, with a p-value less than (p < 0.05), in the head of the second and third metatarsals in statics and dynamics.
CONCLUSIONS: we can conclude that the Morton\'s extension produces a variation in plantar pressures on the lesser metatarsals. The application of a Morton\'s extension may be beneficial for the management of forefoot pathology. This study will help clinicians consider various tools to treat forefoot disorders.

摘要：
背景：跖骨头下方区域是脚部疼痛的常见部位，这通常与高足底压力有关。这项研究的目的是确定使用压力平台应用Morton\'s扩展对足部meta骨压力的影响。
方法：本研究选择了25名没有肌肉骨骼病理学的受试者，以他们为实验对象，在应用莫顿延期之前和之后。将脚部区域划分为前脚（横向细分为与第一个区域相对应的六个区域，第二,第三,第四,第五跖骨头，和幻觉)，中足,和后脚，然后在放置Morton's延伸之前和之后测量每个区域施加的最大和平均压力。
结果：我们发现压力降低，p值小于(p<0.05)，在静力学和动力学的第二和第三meta骨的头部。
结论：我们可以得出结论，Morton的延伸在较小的meta骨上产生了足底压力的变化。Morton扩展的应用可能有利于前足病理学的管理。这项研究将帮助临床医生考虑各种工具来治疗前足疾病。NCT05879094（ClinicalTrial.gov（于2023年5月18日访问））。
