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.
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.
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.
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.
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.
本研究旨在评估患有股骨髋臼撞击综合征（FAI）的患者与无症状个体（对照组）之间在心理、功能和身体方面的差异，分析 4 种 FAI 亚型（凸轮型、凸轮型伴盂唇撕裂、钳夹型和钳夹型伴盂唇撕裂）之间的临床差异，计算所描述变量之间的相关性，并确定导致髋关节功能差异的危险因素。
在一家医院康复科进行了病例对照研究，纳入了一组无症状个体（对照组）和一组患有 FAI 的患者。评估了社会人口统计学特征、疼痛强度、心理健康状况、髋关节活动范围（ROM）、髋关节等长力量和髋关节功能。
共分析了 69 名对照组和 69 名 FAI 患者。尽管两组的社会人口统计学特征相似，但病例组的髋关节 ROM、力量和心理健康状况较差。FAI 亚型之间的疼痛强度、心理健康或 ROM 无显著差异（髋关节内收除外），但髋关节力量存在差异。心理健康、疼痛强度、ROM、力量和髋关节功能之间存在多个显著相关性。国际髋关节结果工具、髋关节日常生活活动评分（HOS）和髋关节运动活动评分（HOS）的方差值分别部分解释（分别为 47.6%、36.0%和 21.6%）基于运动恐惧、髋关节力量、自我效能和焦虑。
与具有相似社会人口统计学特征的无症状个体相比，患有 FAI 的患者心理健康状况较差，髋关节 ROM 和力量较弱。FAI 亚型影响患者的临床表现。髋关节力量、运动恐惧、焦虑和自我效能应作为改善髋关节功能的目标，因为它们已被证明是髋关节功能障碍的重要因素。
本研究表明，疼痛灾难化、髋关节力量和髋关节内收在 FAI 亚型之间存在差异。然而，FAI 亚型之间的髋关节功能和疼痛强度是可比的。
