The main goal of this study was to investigate the size of all portions of the quadriceps muscles in individuals with pronated foot posture compared to normal foot posture using ultrasound imaging.
Twenty nine females with pronated foot posture and 29 age-, body weight-, body height-matched females with normal foot posture were recruited from university communities. The muscle thicknesses of the rectus femoris (RF), vastus medialis (VM), vastus medialis oblique (VMO), vastus lateralis (VL) and vastus intermedius (VI) were measured using ultrasound imaging.
The thicknesses of the RF and VMO were significantly smaller in individuals with pronated foot posture compared to normal foot posture (p<0.05). No significant differences were observed in the VM, VL, and VI muscle thicknesses in both groups.
Based on the results of the present study, it seems that besides the foot and lower leg muscles, an integrated assessment of proximal knee muscles, especially quadriceps, is required in individuals with pronated foot posture.
本研究的主要目的是使用超声成像技术，调查足旋前姿势个体与正常足姿势个体相比，股四头肌各部分的大小。
从大学社区招募了29名足旋前姿势的女性和29名年龄、体重、身高匹配的正常足姿势女性。使用超声成像测量股直肌（RF）、股内侧肌（VM）、股内侧斜肌（VMO）、股外侧肌（VL）和股中间肌（VI）的肌肉厚度。
与正常足姿势个体相比，足旋前姿势个体的RF和VMO厚度显著更小（p<0.05）。两组的VM、VL和VI肌肉厚度均未观察到显著差异。
基于本研究结果，似乎除了足部和小腿肌肉外，对于足旋前姿势个体，还需要对近端膝关节肌肉，尤其是股四头肌进行综合评估。
