Previous studies have reported strength deficit in hip abduction, extension and external rotation in females with patellofemoral pain (PFP) when compared with healthy control; however, there is conflicting evidence for a decrease in hip muscle endurance. Therefore, it seems important to evaluate hip muscle endurance in females with PFP. Moreover, trunk extensor and ankle plantar flexor endurance have not yet been evaluate in females with PFP.
To compare hip abductor, trunk extensor and ankle plantar flexor endurance between females with and without PFP.
Twenty females with PFP (mean age, 21.1 years) and 76 healthy females (mean age, 20.5 years) were recruited. Subject performed three endurance clinical tests: (1) The hip abductor isometric endurance test, (2) The Sorensen test and (3) The heel rise test. Group differences were assessed using an independent t tests, or Mann-Whitney U tests for non-normally distributed data.
Subjects with PFP exhibited significantly lower hip abductor, trunk extensor and ankle plantar flexor endurance than healthy controls. On average, subjects with PFP had deficits of 16% in hip abduction, 14% in trunk extension and 26% in ankle plantar flexion.
Females with PFP exhibited diminished hip abductor, trunk extensor and ankle plantar flexor endurance compared to healthy controls.
先前的研究报告称，与健康对照组相比，患有髌股疼痛（PFP）的女性在髋关节外展、伸展和外旋方面存在力量不足；然而，关于髋部肌肉耐力下降的证据存在矛盾。因此，评估患有PFP的女性的髋部肌肉耐力似乎很重要。此外，尚未对患有PFP的女性的躯干伸肌和踝关节跖屈肌耐力进行评估。
比较患有和未患有PFP的女性之间的髋外展肌、躯干伸肌和踝关节跖屈肌耐力。
招募了20名患有PFP的女性（平均年龄21.1岁）和76名健康女性（平均年龄20.5岁）。受试者进行了三项耐力临床测试：（1）髋关节外展等长耐力测试，（2）索伦森测试和（3）提踵测试。使用独立t检验或对非正态分布数据使用曼-惠特尼U检验评估组间差异。
患有PFP的受试者的髋外展肌、躯干伸肌和踝关节跖屈肌耐力明显低于健康对照组。平均而言，患有PFP的受试者在髋关节外展方面有16%的不足，在躯干伸展方面有14%的不足，在踝关节跖屈方面有26%的不足。
与健康对照组相比，患有PFP的女性的髋外展肌、躯干伸肌和踝关节跖屈肌耐力降低。
