Genuvarum is a common lower limb deformity that affects the alignment of the leg in the frontal plane. This can lead to changes in the ground reaction force (GRF) and center of pressure (COP) of the foot, disrupting postural control strategies, and causing balance issues. This study aimed to determine the effect of strengthening exercises of thigh and abdominal muscles, along with use of a lateral wedge insole (LWI) on balance in young people with genuvarum.
A total of 40 individuals aged 18-40 with genuvarum were split into two groups, with 20 people in each group. Participants in one group received only LWI (LWI group), while those in other group received LWI along with thigh and abdominal muscle strengthening exercises (LWI + exercises group). Balance tests were conducted before and after the 4-week interventions under barefoot condition on a force plate. The tests included parameters related to COP in single- and two-legged standing for static balance, and loading rate of F0 and F1 while walking, peak vertical GRF, and time to reach stability while jumping-landing test for dynamic balance.
In the comparison between LWI + exercises group and LWI group, there was a significant decrease in variables related to COP during single-leg standing and F1 loading rate during walking ( < 0.05).
Incorporating muscle strengthening exercises targeting muscles around the thigh and abdominal region, in addition to using LWI, can be beneficial in individuals' rehabilitation with genuvarum, helping to prevent injuries related to poor posture control. The current study was a randomized clinical trial, registered in the Iranian registry of clinical trials (registration number: IRCT20221103056387N1).
膝外翻是一种常见的下肢畸形，会影响腿部在额状面的对线。这可能导致地面反作用力（GRF）和足部压力中心（COP）发生变化，扰乱姿势控制策略，并引发平衡问题。本研究旨在确定大腿和腹部肌肉强化训练以及使用外侧楔形鞋垫（LWI）对膝外翻年轻人平衡能力的影响。
总共40名年龄在18至40岁之间的膝外翻患者被分为两组，每组20人。一组参与者仅使用LWI（LWI组），而另一组参与者在使用LWI的同时进行大腿和腹部肌肉强化训练（LWI + 训练组）。在4周干预前后，于测力台上在赤足条件下进行平衡测试。测试包括与单腿和双腿站立时静态平衡的COP相关参数、行走时F0和F1的加载率、垂直GRF峰值以及跳跃着陆测试中达到稳定的时间，以评估动态平衡。
在LWI + 训练组和LWI组的比较中，单腿站立时与COP相关的变量以及行走时的F1加载率均显著降低（<0.05）。
除了使用LWI外，进行针对大腿和腹部周围肌肉的强化训练，对膝外翻患者的康复有益，有助于预防与姿势控制不良相关的损伤。本研究是一项随机临床试验，已在伊朗临床试验注册中心注册（注册号：IRCT20221103056387N1）。
