Abstract：
OBJECTIVE: The aims of this study were to assess the psychological, functional, and physical differences between patients with femoroacetabular impingement (FAI) syndrome and individuals who were asymptomatic (controls) to analyze clinical differences among 4 subtypes of FAI (cam type, cam type with labral tear, pincer type, and pincer type with labral tear), to calculate the correlations among the variables described, and to identify risk factors contributing to the hip function variance.
METHODS: A case-control study was conducted at a hospital rehabilitation unit with a cohort of individuals who were asymptomatic (controls) and a cohort of patients with FAI. Sociodemographic characteristics, pain intensity, psychological health status, hip range of motion (RoM), hip isometric strength, and hip function were assessed.
RESULTS: A total of 69 controls and 69 patients with FAI were analyzed. Although sociodemographic characteristics were comparable between samples, poorer hip RoM, strength, and psychological health were found for the cases. FAI subtypes showed no significant pain intensity, psychological health, or RoM differences (except for hip adduction), but hip strength differed among FAI subtypes. Multiple significant correlations between psychological health, pain intensity, RoM, strength, and hip function were found. The variance values of the International Hip Outcome Tool, Hip Outcome Score (HOS) for daily living activities, and HOS for sports activities were partially explained (47.6%, 36.0%, and 21.6%, respectively) on the basis of kinesiophobia, hip strength, self-efficacy, and anxiety.
CONCLUSIONS: Patients with FAI showed poorer psychological health, hip RoM, and strength than individuals who were asymptomatic and had similar sociodemographic characteristics. FAI subtype influenced the patients\' clinical presentations. Hip strength, kinesiophobia, anxiety, and self-efficacy should be targeted for improving hip function, as they have been demonstrated to be important contributors to hip disability.
CONCLUSIONS: This study demonstrated that pain catastrophizing, hip strength, and hip adduction differed among FAI subtypes. However, hip function and pain intensity were comparable between FAI subtypes.

摘要：
目的：本研究的目的是评估心理，功能，以及股骨髋臼撞击（FAI）综合征患者与无症状个体（对照）之间的身体差异，以分析FAI的4种亚型（凸轮型，带唇瓣撕裂的凸轮类型，夹式,和夹式与唇撕裂)，为了计算所描述的变量之间的相关性，并确定导致髋关节功能变异的危险因素。
方法：在医院康复病房进行了一项病例对照研究，其中包括一组无症状者（对照组）和一组FAI患者。社会人口统计学特征，疼痛强度，心理健康状况，髋关节运动范围（RoM），髋部等距强度,和髋关节功能进行评估。
结果：共分析了69例对照和69例FAI患者。尽管样本之间的社会人口统计学特征具有可比性，更穷的臀部RoM，力量,发现这些病例的心理健康。FAI亚型无明显疼痛强度,心理健康,或RoM差异（除髋关节内收），但不同FAI亚型的髋关节力量不同。心理健康之间的多重显著相关，疼痛强度，RoM,力量,髋关节功能被发现。国际髋关节结果工具的方差值，日常生活活动的髋关节结果评分，部分解释了体育活动的髋关节结果得分(47.6%，36.0%,和21.6%，分别)在运动恐惧症的基础上，髋部力量,自我效能感,和焦虑。
结论：FAI患者的心理健康状况较差，臀部RoM,与无症状且具有相似社会人口统计学特征的个体相比，强度更高。FAI亚型影响患者的临床表现。臀部力量,运动恐惧症,焦虑,自我效能感应该是改善髋关节功能的目标，因为他们已经被证明是髋关节残疾的重要贡献者。
结论：这项研究表明，痛苦灾难，髋部力量,FAI亚型之间的髋关节内收不同。然而,FAI亚型之间的髋关节功能和疼痛强度相当.
