Atypical running gait biomechanics are considered a primary factor in the etiology of iliotibial band syndrome (ITBS). However, a general consensus on the underpinning kinematic differences between runners with and without ITBS is yet to be reached. This lack of consensus may be due in part to three issues: gender differences in gait mechanics, the preselection of discrete biomechanical variables, and/or relatively small sample sizes. Therefore, this study was designed to address two purposes: (a) examining differences in gait kinematics for male and female runners experiencing ITBS at the time of testing and (b) assessing differences in gait kinematics between healthy gender- and age-matched runners as compared with their ITBS counterparts using waveform analysis. Ninety-six runners participated in this study: 48 ITBS and 48 healthy runners. The results show that female ITBS runners exhibited significantly greater hip external rotation compared with male ITBS and female healthy runners. On the contrary, male ITBS runners exhibited significantly greater ankle internal rotation compared with healthy males. These results suggest that care should be taken to account for gender when investigating the biomechanical etiology of ITBS.
非典型跑步步态生物力学被认为是髂胫束综合征（ITBS）病因的一个主要因素。然而，对于有和没有ITBS的跑步者之间潜在的运动学差异，尚未达成普遍共识。这种缺乏共识可能部分归因于三个问题：步态力学中的性别差异、离散生物力学变量的预先选择和/或相对较小的样本量。因此，本研究旨在实现两个目的：（a）检查在测试时患有ITBS的男性和女性跑步者的步态运动学差异，以及（b）使用波形分析评估健康的性别和年龄匹配的跑步者与其患有ITBS的对应者之间的步态运动学差异。九十六名跑步者参与了本研究：48名患有ITBS的跑步者和48名健康跑步者。结果表明，与男性ITBS跑步者和女性健康跑步者相比，女性ITBS跑步者表现出明显更大的髋关节外旋。相反，与健康男性相比，男性ITBS跑步者表现出明显更大的踝关节内旋。这些结果表明，在研究ITBS的生物力学病因时，应注意考虑性别因素。
