Abstract
Enough dorsiflexion angle of the first metatarsophalangeal joint is needed to ensure thrust and stability [1], and if the range of motion of the first metatarsophalangeal joint decreases, normal foot function during gait is under severe restriction [2]. Wearing shoes with high heels during gait makes weight leaning forward and wearing them for long may cause deformation of hallux valgus [3,4]. General therapeutic concepts of foot diseases focus on reducing or eliminating plantar tissue stress. Recently, studies on treatment to solve these problems have been conducted, but there have been a few studies on orthotic devices such as metatarsal pad, dome and wedge [5]. Therefore, this study applied bar metatars ophalangeal area of normal persons and examined if any change occurs of spatio-temporal indices and kinematic parameters by using 3D motion analysis system.

This study applied bar metatars ophalangeal area of normal persons and examined if any change occurs of spatio-temporal indices and kinematic parameters by using 3D motion analysis system
Spatio-temporal indices including stance phase, swing phase, double phase, cadence, stride time, stance phase time, swing phase time, double stance phase time, step length, stride length, velocity, stride velocity, and swing phase velocity were measured through 3D motion analysis system and kinematic parameters such as pelvic tilt angle, hip joint flexionextension angle, knee joint flexion-extension angle, foot progression angle, and ankle joint flexion-extension angle were measured through 3D motion analysis system
