The purpose of this study was to determine the relationship of the static angle of the rearfoot during single leg standing, relaxed standing foot posture, and subtalar joint neutral position with the pattern of rearfoot motion during walking. The authors felt that this study was important to gain a better understanding of the relationship between dynamic rearfoot motion and three static rearfoot angles which are often included in foot examination procedures. The pattern of rearfoot motion was assessed using two-dimensional video recordings for each lower extremity of 31 healthy young adult subjects with a mean age of 25.2 years. The mean path of rearfoot motion during walking crossed relaxed standing foot posture but did not cross single leg standing or subtalar neutral position. These findings suggest that the mean path of rearfoot motion during the first 60% of the walking cycle occurs between the static angles of relaxed standing foot posture and single leg standing. In addition, the static angle of the rearfoot in single leg standing may serve as a clinical indicator of the degree of maximum rearfoot eversion occurring during the walking cycle.
本研究的目的是确定单腿站立、放松站立足部姿势以及距下关节中立位时后足的静态角度与行走过程中后足运动模式之间的关系。作者认为，这项研究对于更好地理解动态后足运动与足部检查程序中经常包含的三个后足静态角度之间的关系非常重要。使用二维视频记录对31名平均年龄为25.2岁的健康年轻成年受试者的每个下肢进行后足运动模式评估。行走过程中后足运动的平均轨迹穿过放松站立足部姿势，但未穿过单腿站立或距下中立位。这些发现表明，在行走周期的前60%，后足运动的平均轨迹出现在放松站立足部姿势和单腿站立的静态角度之间。此外，单腿站立时后足的静态角度可作为行走周期中后足最大外翻程度的临床指标。
