Comparing the Foot Pressure between Flat Foot & Normal Foot with Single Leg Standing

Objective : The aim of this study is verification of a person has normal foot arch and person has flatfoot have different plantar pressure in single leg standing position. Methods : A total of 20 participants were divided into groups with 9 flatfoot group and 11 normal foot arch group through the navicular drop test. Two groups measured the foot pressure during single leg standing on attached each sensor to four different parts. Using the Trigno Wireless Systems, four different foot areas(1st Toe, 1st metatarsal base, 5th metatarsal base and heel) pressure were measured. Different of foot pressure according to flatfoot and normal foot were analyzed through independent t-test. Results : The results in flatfoot group plantar pressure has been biased to the 1st metatarsal base and heel compared to the result of plantar pressure in normal foot group during single leg standing(p<.05). Normal foot arch group and flatfoot group have no significant different in 1st toe and 5th metatarsal base of plantar pressure during single leg standing. Conclusion : Though this study, flat foot subjects had more high foot pressure toward to lateral and posterior than normal foot subjects.
