To compare the plantar pressure distribution and the kinematics of the rearfoot on the stance phase of subjects with or without patellofemoral pain syndrome (PFPS). A total of 26 subjects with PFPS and 31 clinically healthy subjects, who were paired regarding age, height and mass, participated in the study. The plantar pressure distribution (peak pressure) was assessed in six plantar regions, as well as the kinematics of the rearfoot (maximum eversion angle, percentage of the stance phase when the maximum angle was reached, and percentage of the stance phase in which the rearfoot was in eversion). The data were analyzed by descriptive and inferential statistics, with a significance level of ≤ 0.05. The pressure on the six plantar regions analyzed and the magnitude of the maximum eversion angle of the rearfoot when walking on flat surfaces did not present differences among the subjects with PFPS. However, the PFPS subjects showed, when walking, an earlier maximum eversion angle of the rearfoot than the subjects on the control group, and stayed less time with the rearfoot in eversion. The PFPS seems to be related to modifications on the temporal pattern on the kinematics of the rearfoot.
比较有或没有髌股疼痛综合征（PFPS）的受试者在站立期的足底压力分布和后足运动学。 共有26名患有PFPS的受试者和31名临床健康受试者参与了该研究，他们在年龄、身高和体重方面进行了配对。评估了六个足底区域的足底压力分布（峰值压力）以及后足的运动学（最大外翻角度、达到最大角度时站立期的百分比以及后足处于外翻状态时站立期的百分比）。数据采用描述性和推断性统计分析，显著性水平≤0.05。 在平坦表面行走时，分析的六个足底区域的压力以及后足最大外翻角度的大小在患有PFPS的受试者之间没有差异。然而，PFPS受试者在行走时后足的最大外翻角度比对照组受试者出现得更早，并且后足处于外翻状态的时间更短。 PFPS似乎与后足运动学时间模式的改变有关。
