研究设计：横断面实验实验室研究。目的：研究以前患有髂胫束综合征（ITBS）的跑步者和没有膝盖相关跑步损伤的跑步者在跑步力学方面的差异。背景：ITBS是跑步者膝关节疼痛的第二大原因，也是膝关节外侧疼痛的最常见原因。尽管它很普遍，但很少有生物力学研究来更好地了解其病因。因为髂胫束有股骨和胫骨的附着，不典型的髋关节和足部力学可能导致ITBS的发展。方法：将35名曾经经历过ITBS的女性与35名年龄匹配和跑步距离匹配的健康女性的跑步机制进行比较。比较了跑步步态站立阶段的髋关节、膝关节和踝关节的三维运动学和内部力矩。结果：与对照组相比，ITBS组表现出更大的后足反转力矩峰值、膝关节内旋角峰值和髋关节内收角峰值。两组患者后足外翻角峰值、膝关节屈曲角峰值、膝关节外旋力矩峰值、髋外展力矩峰值均无显著差异。结论：有ITBS病史的女性表现出髂胫束应力增加的运动学特征。这些结果与在相同实验室环境下进行的前瞻性研究的结果大致相似。[J] .体育学报，2010;40(2):52-58。doi: 10.2519 / jospt.2010.3028
STUDY DESIGN: Cross-sectional experimental laboratory study.OBJECTIVE: To examine differences in running mechanics between runners who had previously sustained iliotibial band syndrome (ITBS) and runners with no knee-related running injuries.BACKGROUND: ITBS is the second leading cause of knee pain in runners and the most common cause of lateral knee pain. Despite its prevalence, few biomechanical studies have been conducted to better understand its aetiology. Because the iliotibial band has both femoral and tibial attachments, it is possible that atypical hip and foot mechanics could result in the development of ITBS.METHODS: The running mechanics of 35 females who had previously sustained ITBS were compared to 35 healthy age-matched and running distance-matched healthy females. Comparisons of hip, knee, and ankle 3-dimensional kinematics and internal moments during the stance phase of running gait were measured.RESULTS: The ITBS group exhibited significantly greater peak rearfoot invertor moment, peak knee internal rotation angle, and peak hip adduction angle compared to controls. No significant differences in peak rearfoot eversion angle, peak knee flexion angle, peak knee external rotator moment, or peak hip abductor moments were observed between groups.CONCLUSION: Females with a previous history of ITBS demonstrate a kinematic profile that is suggestive of increased stress on the iliotibial band. These results were generally similar to those reported for a prospective study conducted within the same laboratory environment. J Orthop Sports Phys Ther 2010;40(2):52-58. doi:10.2519/jospt.2010.3028
