Study Design Controlled laboratory study, case-control design. Background Despite recognition that femoroacetabular impingement syndrome (FAIS) is a movement-related disorder, few studies have examined dynamic unilateral tasks in individuals with FAIS. Objectives To determine whether movements of the pelvis and lower extremities in individuals with FAIS differ from those in individuals without hip pain during a single-leg step-down, and to analyze kinematic differences between male and female participants within groups. Methods Individuals with FAIS and individuals without hip pain performed a single-leg step-down while kinematic data were collected. Kinematics were evaluated at 60° of knee flexion. A linear regression analysis assessed the main effects of group, sex, and side, and the interaction of sex by group. Results Twenty individuals with FAIS and 40 individuals without hip pain participated. Individuals with FAIS performed the step-down with greater hip flexion (4.9°; 95% confidence interval [CI]: 0.5°, 9.2°) and anterior pelvic tilt (4.1°; 95% CI: 0.9°, 7.3°) than individuals without hip pain. Across groups, female participants performed the task with more hip flexion (6.1°; 95% CI: 1.7°, 10.4°), hip adduction (4.8°; 95% CI: 2.2°, 7.4°), anterior pelvic tilt (5.8°; 95% CI: 2.6°, 9.0°), pelvic drop (1.4°; 95% CI: 0.3°, 2.5°), and thigh adduction (2.7°; 95% CI: 1.3°, 4.2°) than male participants. Conclusion The results of this study suggest that individuals with FAIS have alterations in pelvic motion during a dynamic unilateral task. The noted altered movement patterns in the FAIS group may contribute to the development of hip pain and may be due to impairments that are modifiable through rehabilitation.

对照实验室研究，病例对照设计。
尽管人们已经认识到，股骨髋臼撞击综合征（FAIS）是一种与运动相关的疾病，但很少有研究在 FAIS 患者中检查过单侧动态任务。
确定 FAIS 患者在单腿台阶下降过程中，骨盆和下肢的运动是否与无髋痛患者不同，并分析组内男女参与者之间的运动学差异。
FAIS 患者和无髋痛患者在进行单腿台阶下降时收集运动学数据。在膝关节屈曲 60°时评估运动学。线性回归分析评估了组、性别和侧别以及组间性别的主要效应。
20 名 FAIS 患者和 40 名无髋痛患者参与了研究。FAIS 患者在台阶下降时髋关节屈曲度更大（4.9°；95%置信区间[CI]：0.5°，9.2°），骨盆前倾角度更大（4.1°；95%CI：0.9°，7.3°）。在所有组中，女性参与者髋关节屈曲度更大（6.1°；95%CI：1.7°，10.4°），髋关节内收度更大（4.8°；95%CI：2.2°，7.4°），骨盆前倾角度更大（5.8°；95%CI：2.6°，9.0°），骨盆下降角度更大（1.4°；95%CI：0.3°，2.5°），大腿内收度更大（2.7°；95%CI：1.3°，4.2°）。
本研究结果表明，FAIS 患者在动态单侧任务中骨盆运动发生改变。FAIS 组注意到的运动模式改变可能导致髋部疼痛的发生，并且可能是由于通过康复可以改善的功能障碍。
