摘　　要：目的研究髌股关节痛(patellofemoral pain,PFP)业余跑者性别特异的下肢生物力学特征。方法选取15名男性和10名女性PFP业余跑者作为实验组,并匹配25名无损伤业余跑者作为对照组。采集所有受试者跑步时的下肢运动学、动力学和表面肌电数据。采用双因素方差分析确定组别与性别对跑步时下肢生物力学特征的影响。结果男性PFP业余跑者跑步缓冲期最大膝屈角度显著大于对照组;男性和女性PFP业余跑者跑步缓冲期最大髋内收角度显著大于对照组,且女性显著大于男性。结论不同性别PFP业余跑者在跑步时表现出不同的下肢生物力学特征,PFP临床治疗应具有性别特异性。Objective To study the sex-specific lower extremity biomechanics of amateur runners with patellofemoral pain(PFP).Methods Fifteen male and ten female amateur runners with PFP were identified and enrolled in PFP group,twenty-five healthy amateur runners matched with the PFP group were recruited as control group.The kinematics and kinetics,surface electromyography(EMG)data from all the subjects in the running task were collected.Two-way analysis of variance was performed to determine the influence of group and sex on lower extremity biomechanics during running.Results Compared with control group,male amateur runners with PFP showed a greater peak knee flexion angle during the landing phase of running.Compared with control group,male and female amateur runners with PFP showed a greater peak hip adduction angle during the landing phase of running,while the peak hip adduction angle of female participants was significantly greater than that of male participants.Conclusions Amateur runners with PFP showed sex-specific lower extremity biomechanics in the running task,and the clinical intervention for PFP should be sex-specific.
