보행시 아웃토잉의 지면반력과 압력분포분석

The purposes of this study were to compare normal gait and out-toeing and collect quantitative data for reducing fatigue and injury from out-toeing. Subjects were classified into 2 groups, 4 in each ; normal gait and out-toeing. The following kinematic variables were calculated in relation to gait patterns ; ground reaction forces and foot pressure distributions. Based on the results of this study, the following conclusions were drawn: Even though out-toeing showed the smaller ground reaction force than that of normal gait, this could be the cause of fatigue and injury of musdes, tendons, and bones related to gait. This was because of maximal pressure in the lateral part of the rear foot and the internal part of the fore foot. Therefore, extending support time to reduce impact and walking using all parts of the foot evenly are effective methods. Furthermore, shoes made of different soles to absorb the excessive impact in particular parts(lateral parts of the rear foot and internal parts of the fore foot) might be beneficial for solving this problem.
