Identifying biomechanical impairments in young, physically active populations with hip/groin pain is crucial for early intervention. This study characterized the biomechanical features of a novel task, the , in competitive football players, comprising 36 individuals with hip/groin pain (28 ± 6 years) and 11 controls (26 ± 4 years). Experimental motion data and ground forces were input into biomechanical models to calculate joint angles and moments, then transformed into principal components and input into a feature selection pipeline. Ten main biomechanical features were identified for each limb, i.e. the pivot limb and the swing limb, that could discriminate between symptomatic and control groups with < 0.05. In symptomatic individuals, the main features were as follows: : smaller hip flexion and knee extension angles, delayed initiation of hip flexion and increased ankle dorsiflexion moment; : reduced hip flexion moment, increased hip internal rotation moment, delayed hip adduction and knee extension moments, and reduced ankle dorsiflexion angle. The largest group differences occurred during the transitions from step-down to pivot, and pivot to step-forward, supporting a potential role for multi-phase and/or multi-planar tasks when assessing biomechanical impairments due to hip/groin pain. Although biomechanical alterations in our symptomatic participants were small, they could be identified and characterized using feature selection.
识别有髋部/腹股沟疼痛的年轻、身体活跃人群的生物力学损伤对于早期干预至关重要。本研究描述了一项新任务的生物力学特征，该任务在竞技足球运动员中进行，包括36名有髋部/腹股沟疼痛的个体（28±6岁）和11名对照组（26±4岁）。将实验运动数据和地面力输入生物力学模型以计算关节角度和力矩，然后转换为主成分并输入特征选择流程。为每个肢体（即枢轴肢体和摆动肢体）确定了10个主要生物力学特征，这些特征能够以<0.05的水平区分症状组和对照组。在有症状的个体中，主要特征如下：枢轴肢体：较小的髋关节屈曲和膝关节伸展角度、髋关节屈曲起始延迟以及踝关节背屈力矩增加；摆动肢体：髋关节屈曲力矩减小、髋关节内旋力矩增加、髋关节内收和膝关节伸展力矩延迟以及踝关节背屈角度减小。最大的组间差异发生在从下台阶到枢轴以及从枢轴到向前迈步的过渡过程中，这支持了在评估由髋部/腹股沟疼痛引起的生物力学损伤时多阶段和/或多平面任务的潜在作用。尽管我们有症状参与者的生物力学改变很小，但可以使用特征选择来识别和描述这些改变。
