The Effect of a Discharge Sock Model in Comfort: Randomized Controlled Trial

Metatarsalgia is a common set of symptoms in the forefoot, characterized by pain under one or more metatarsal heads. The invention of a utility model, the U202030700, designed by the study\'s principal investigator aims to protect the metatarsus and prevent the appearance of foot pain. The hypothesis of this research project is based on the fact that using our proposed sock with metatarsal discharge plate will bring advantages in terms of pain reduction, increased comfort, temperature reduction and change in plantar pressures received in the second and third metatarsals joint area versus the use of control socks (without discharge plate). Participants will be subjects with pain in the plantar metatarsal area that will answer few questions and a podiatric exam to determine if meet the study requirements and then a plantar pressures, foot temperature and confort wit the two kind of socks will be taken. Confort survey, thermal pictures and plantar pressures will be taken (in first term) before and after a brief walk (5 to 10 minutes) and in a second experiment (second term) after a long walk (more than 1 hour).
