研究设计：描述性，队列设计。结论：为了全面研究静态下肢对齐（莱亚）临床测量中的性别差异，背景：莱亚的性别差异已被纳入无数的风险因素中，作为女性膝关节损伤患病率增加的潜在原因。虽然临床观察表明莱亚存在性别差异，但很少有经验数据支持这些性别差异或健康人群中应预期的正常值。方法和措施：100名健康大学生年龄参与者的右侧和左侧静态莱亚（50例男性[平均+/- SD年龄，23.3 +/- 3.6岁;身高，177.8 +/- 8.0 cm，体重，80.4 +/- 11.6 kg]和50例女性[平均+/- SD年龄，21.8 +/- 2.5岁;身高，164.3 +/- 6.9 cm;体重，674 +/-15.2kg]）。每个对齐特征进行了分析，通过单独的重复测量方差分析，与I间的主题因素（性别）和1内的主题因素（侧）。结果：没有显着的性别侧之间的相互作用，双方之间没有差异。女性的平均骨盆前倾角、髋关节前倾、股四头肌角、胫股角和前屈均大于男性（P <0.0001）。胫骨扭转（P = 0.131）、舟骨下降（P = 0.130）和后足角度（P = 0.590）无性别差异。结论：莱亚的性别差异表明，平均而言，女性具有更大的骨盆前倾、大腿内旋、膝外翻和膝后反屈。这些性别差异并不伴随着小腿，脚踝和脚的差异。了解这些集体性别差异在莱亚可能有助于我们更好地检查莱亚对动态下肢功能的影响，并澄清其作为一个潜在的损伤危险因素的作用。
STUDY DESIGN: Descriptive, cohort design.OBJECTIVES: To comprehensively examine sex differences in clinical measures of static lower extremity alignment (LEA).BACKGROUND: Sex differences in LEA have been included among a myriad of risk factors as a potential cause for the increased prevalence of knee injury in females. While clinical observations suggest that sex differences in LEA exist, little empirical data are available to support these sex differences or the normal values that should be expected in a healthy population.METHODS AND MEASURES: The right and left static LEA of 100 healthy college-age participants (50 males [mean +/- SD age, 23.3 +/- 3.6 years; height, 177.8 +/- 8.0 cm, body mass, 80.4 +/- 11.6 kg] and 50 females [mean +/- SD age, 21.8 +/- 2.5 years; height, 164.3 +/- 6.9 cm; body mass, 674 +/- 15.2 kg]) was measured. Each alignment characteristic was analyzed via separate repeated-measures analyses of variance, with I between-subject factor (sex) and 1 within-subject factor (side).RESULTS: There were no significant sex-by-side interactions and no differences between sides. Females had greater mean anterior pelvic tilt, hip anteversion, quadriceps angles, tibio-femoral angles, and genu recurvatum than males (P < .0001). No sex differences were observed in tibial torsion (P = .131), navicular drop (P = .130), and rearfoot angle (P = .590).CONCLUSION: Sex differences in LEA indicate that females, on average, have greater anterior pelvic tilt, thigh internal rotation, knee valgus, and genu recurvatum. These sex differences were not accompanied by differences in the lower leg, ankle, and foot. Understanding these collective sex differences in LEA may help us to better examine the influence of LEA on dynamic lower extremity function and clarify their role as a potential injury risk factor.
