Abstract
Joint moment and power of the metatarsophalangeal MP joint in normal horizontal barefoot walking were determined in this study The threedimensional motion analysis with synchronous measurements of ground reaction forces and foot pressure distribution was performed with the twosegment foot model Twentytwo adult subjects were selected for the study Compared to the previous studies results of this study showed reasonable joint moments from footflat to toeoff The MP joint angles showed a very good agreement with the previous studies The maximum MP joint moment was 013 ± 004 Nm/kg at preswing approximately onetenth of the ankle joint moment A considerable energy absorption of approximately 656 GC J/kg was found at the MP joint during 30~60 of the gait cycle This study would be beneficial to understand the mechanism of various foot diseases such as hallux valgus and plantar fasciitis
