BACKGROUND/PURPOSE: Decreased strength of the hip musculature and altered mechanics of the lower extremity have been identified in individuals with patellofemoral pain (PFP). The aim of this study was to determine if a relationship exists between hip muscle strength and transverse and frontal plane motion at the hip and knee, and ipsilateral trunk flexion during a jump-landing task in individuals with PFP.
Fifteen individuals (10 females, 5 males) with PFP participated in this investigation. A three-dimensional motion analysis system was utilized to assess trunk, hip, and knee kinematics during a jump-landing task. An isokinetic dynamometer was utilized to assess concentric and eccentric strength of the hip musculature. Simple correlation analyses were performed to determine the relationships between hip muscle strength and peak frontal and transverse plane hip and knee kinematics and ipsilateral trunk flexion.
Decreased eccentric strength of the hip external rotators and abductors was significantly correlated to increased frontal plane motion at the hip and trunk, respectively (P<0.05).
Based on these findings, eccentric strengthening exercises for the hip musculature may be an important component for clinicians to include when rehabilitating individuals with PFP who display increased frontal plane motion at the hip and trunk.

背景/目的:髌股疼痛(PFP)患者已被证实存在髋部肌肉力量下降和下肢力学改变的情况。本研究旨在确定PFP患者在跳跃着陆任务中,髋部肌肉力量与髋、膝关节在矢状面和额状面的运动以及同侧躯干屈曲之间是否存在关联。
15名PFP患者(10名女性,5名男性)参与了本研究。使用三维运动分析系统评估跳跃着陆任务期间的躯干、髋部和膝部运动学。使用等速测力计评估髋部肌肉的向心和离心力量。进行简单相关分析以确定髋部肌肉力量与髋、膝关节在额状面和矢状面的峰值运动学以及同侧躯干屈曲之间的关系。
髋部外旋肌和外展肌离心力量下降分别与髋部和躯干在额状面的运动增加显著相关(P<0.05)。
基于这些发现,对于在髋部和躯干额状面运动增加的PFP患者,髋部肌肉的离心强化训练可能是临床医生在康复过程中应纳入的重要组成部分。
