Previous studies have demonstrated increased medial stresses in knee varus alignment. Selecting a suitable treatment strategy for individuals with knee malalignment should be a priority.
We aimed to investigate the effects of a 16-week corrective exercise continuum (CEC) program on 3-D joint angles of the dominant and non-dominant lower limbs in children with genu varus during walking.
Overall, 28 male children with genu varus (age range 9-14 years) volunteered to participate in this study. They were randomly divided into 2 equal groups (experimental and control). The participants of the experimental group received CEC for 16 weeks. 3-D gait analysis involved using a Vicon Motion System. Paired and independent sample t-tests were used for within- and between-group comparisons, respectively.
For the experimental group, comparison of pre- and post-test joint kinematics of the dominant lower limb revealed that CEC decreased the peak ankle dorsiflexion angle by 26% (P=0.020), peak foot internal rotation angle by 53% (P=0.001), peak knee internal rotation angle by 40% (P=0.011), peak hip abduction by 47% (P=0.010), and peak hip external rotation angle by 60% (P=0.001). In contrast, peak knee external rotation angle of the dominant limb was increased after the training program by 46% (P=0.044). For the non-dominant lower limb, CEC decreased the peak ankle inversion by 63% (P<0.01), peak ankle eversion by 91% (P<0.01), peak foot internal rotation by 50% (P<0.01), peak knee internal rotation by 29%; P=0.042), peak hip abduction angle by 38% (P<0.01), and peak hip external rotation angle by 60% (P<0.01).
CEC therapy reduced excessive foot and knee internal rotations as well as excessive hip external rotation during walking in children with genu varus.
先前的研究表明，膝内翻患者的内侧压力增加。选择合适的治疗策略应成为治疗膝内翻患者的首要任务。
本研究旨在探究 16 周矫正运动连续体（CEC）方案对膝内翻儿童在步行过程中双侧下肢三维关节角度的影响。
共有 28 名男性膝内翻儿童（9-14 岁）自愿参与本研究。他们被随机分为两组（实验组和对照组）。实验组接受 CEC 治疗 16 周。采用 Vicon 运动系统进行三维步态分析。采用配对样本 t 检验和独立样本 t 检验分别对组内和组间比较。
实验组患者的主要下肢在接受 CEC 前后的关节运动学比较中发现，CEC 降低了足背屈峰值角度 26%（P=0.020）、足内旋峰值角度 53%（P=0.001）、膝内旋峰值角度 40%（P=0.011）、髋关节外展峰值角度 47%（P=0.010）和髋关节外旋峰值角度 60%（P=0.001）。相反，经过训练后，优势侧下肢的膝外旋峰值角度增加了 46%（P=0.044）。非优势下肢，CEC 降低了足内翻峰值角度 63%（P<0.01）、足外翻峰值角度 91%（P<0.01）、足内旋峰值角度 50%（P<0.01）、膝内旋峰值角度 29%（P=0.042）、髋关节外展峰值角度 38%（P<0.01）和髋关节外旋峰值角度 60%（P<0.01）。
CEC 疗法可降低膝内翻儿童在行走时过度的足内翻和膝内旋以及过度的髋关节外旋。
