Proximal and distal influences on the knee may be related as etiological factors of patellofemoral pain syndrome (PFPS). The distal factors include subtalar excessive pronation as well as medial tibia rotation, but no study has investigated whether ankle weakness could lead to alterations that influence the patellofemoral joint. Thus, the purpose of this study was to compare the ankle dorsiflexor and invertor muscles strength, as well as rearfoot eversion and the Navicular Drop Test (NDT) in females with PFPS to a control group of females of similar demographics without PFPS.
Forty females, between 20 and 40 years of age (control group: n=20; PFPS group: n=20) participated. Rearfoot eversion range of motion and the NDT were assessed for both groups. The Numeric Pain Rating Scale and the Anterior Knee Pain Scale were used to evaluate the level of pain and the functional capacity of the knee during activities, respectively. Isometric ankle dorsiflexor and invertor strength was measured using a handheld dynamometer as the dependent variable.
The isometric strength of the dorsiflexor and invertor muscle groups in females with PFPS was not statistically different (P>0.05) than that of the control group. There was no statistically significant difference between groups for rearfoot eversion and NDT (p>0.05).
DISCUSSION/CONCLUSION: These results suggest that there is no difference between isometric ankle dorsiflexion and inversion strength, the NDT, and rearfoot eversion range of motion in females with and without PFPS.

对膝关节的近端和远端影响可能作为髌股疼痛综合征（PFPS）的病因因素而相关。远端因素包括距下关节过度旋前以及胫骨内侧旋转，但尚无研究调查踝关节无力是否会导致影响髌股关节的改变。因此，本研究的目的是比较患有PFPS的女性与年龄、人口统计学特征相似的无PFPS女性对照组在踝关节背屈肌和内翻肌力量、后足外翻以及舟骨下降试验（NDT）方面的差异。
40名年龄在20至40岁之间的女性参与研究（对照组：n = 20；PFPS组：n = 20）。对两组均评估后足外翻活动范围和NDT。分别使用数字疼痛评分量表和前膝疼痛量表评估疼痛程度和活动期间膝关节的功能能力。使用手持测力计测量等长踝关节背屈肌和内翻肌力量作为因变量。
患有PFPS的女性中，背屈肌和内翻肌群的等长力量与对照组相比无统计学差异（P>0.05）。两组在后足外翻和NDT方面无统计学显著差异（p>0.05）。
讨论/结论：这些结果表明，患有和未患有PFPS女性在等长踝关节背屈和内翻力量、NDT以及后足外翻活动范围方面没有差异。
