背景：女性跑步者有很高的髌股关节疼痛发生率。异常力学被认为是髌股关节疼痛的一个重要因素。然而，在这个队列中，躯干、髋关节和足部力学异常对髌股关节疼痛的影响仍然是难以捉摸的。因此，本研究的目的是确定是否存在显着差异，在运行过程中的髋关节，躯干和脚的运动学之间的女性和没有髌股关节疼痛。方法：32名女性跑步者（16髌股关节疼痛，16名健康对照）参加了这项研究。所有人都进行了仪器步态分析。对髋内收、髋内旋、对侧骨盆下降、对侧躯干倾斜进行组间比较。后足外翻、胫骨内旋转以及前足背屈和外展发现：髌股疼痛组的峰值髋关节内收和髋关节内旋转明显更大。在对侧骨盆下降方面没有发现差异。在髌股关节疼痛组中发现了对侧躯干倾斜减少的趋势。没有显着差异，发现在任何rearfoot或forefoot变量，但显着更大的小腿内旋被发现在髌股关节疼痛group.Interpretation：我们发现更大的髋关节内收，髋关节内旋和小腿内旋在女性跑步者髌股关节疼痛。我们还发现髌股关节疼痛组的躯干对侧倾斜较少。这可能是髋关节控制不良的潜在补偿机制。在这一人群中，纠正髋关节和小腿运动学异常的康复计划是必要的。(C)2011爱思唯尔有限公司保留所有权利。
Background: Female runners have a high incidence of developing patellofemoral pain. Abnormal mechanics are thought to be an important contributing factor to patellofemoral pain. However, the contribution of abnormal trunk, hip, and foot mechanics to the development of patellofemoral pain within this cohort remains elusive. Therefore the aim of this study was to determine if significant differences during running exist in hip, trunk and foot kinematics between females with and without patellofemoral pain.Methods: 32 female runners (16 patellofemoral pain, 16 healthy control) participated in this study. All individuals underwent an instrumented gait analysis. Between-group comparisons were made for hip adduction, hip internal rotation, contra-lateral pelvic drop, contra-lateral trunk lean. rearfoot eversion, tibial internal rotation, as well as forefoot dorsifiexion and abductionFindings: The patellofemoral pain group had significantly greater peak hip adduction and hip internal rotation. No differences in contra-lateral pelvic drop were found. A trend towards reduced contra-lateral trunk lean was found in the patellofemoral pain group. No significant differences were found in any of the rearfoot or forefoot variables but significantly greater shank internal rotation was found in the patellofemoral pain group.Interpretation: We found greater hip adduction, hip internal rotation and shank internal rotation in female runners with patellofemoral pain. We also found less contra-lateral trunk lean in the patellofemoral pain group. This may be a potential compensatory mechanism for the poor hip control seen. Rehabilitation programs that correct abnormal hip and shank kinematics are warranted in this population. (C) 2011 Elsevier Ltd. All rights reserved.
