The aim of this study was to determine the effect of the application of a Morton\u2019s 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\u2019s 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\u2019s extension. Main findings: we found a pressure reduction, with a p-value less than (p &lt; 0.05), in the head of the second and third metatarsals in statics and dynamics. Conclusions: we can conclude that the Morton\u2019s extension produces a variation in plantar pressures on the lesser metatarsals. The application of a Morton\u2019s extension may be beneficial for the management of forefoot pathology. This study will help clinicians consider various tools to treat forefoot disorders.
