研究设计：横断面。目的：研究与对照组相比，寻求单侧髌股疼痛综合征（PFPS）物理治疗的女性是否表现出髋关节力量不足。背景：髋关节力量下降可能与负重活动时下肢运动控制不良有关，导致髌骨运动异常和疼痛。先前研究PFPS患者髋部力量受损的研究报告了相互矛盾的结果。方法与措施：20名女性，年龄12 ~ 35岁。10名患有单侧PFPS的受试者与10名没有已知膝关节病变的对照组进行比较。使用手持式测力仪测试髋关节外展、伸展和外旋强度。肢体对称指数（LSI）用于量化所有测试的身体表现。结果：PFPS受试者的症状肢体在所有测试变量中都表现出髋关节力量的损伤。PFPS患者的LSI值（范围，71%-79%）显著低于对照组（范围，93%-101%）
STUDY DESIGN: Cross-sectional.OBJECTIVES: To investigate whether females seeking physical therapy treatment for unilateral patellofemoral pain syndrome (PFPS) exhibit deficiencies in hip strength compared to a control group.BACKGROUND: Decreased hip strength may be associated with poor control of lower extremity motion during weight-bearing activities, leading to abnormal patellofemoral motions and pain. Previous studies exploring the presence of hip strength impairments in subjects with PFPS have reported conflicting results.METHODS AND MEASURES: Twenty females, aged 12 to 35 years, participated in the study. Ten subjects with unilateral PFPS were compared to 10 control subjects with no known knee pathologies. Hip abduction, extension, and external rotation strength were tested using a handheld dynamometer. A limb symmetry index (LSI) was used to quantify physical performance for all tests.RESULTS: The symptomatic limbs of subjects with PFPS exhibited impairments in hip strength for all variables tested. LSI values in subjects with PFPS (range, 71%-79%) were significantly lower than those in control subjects (range, 93%-101%) (P
