Our study aimed to examine preoperative differences in strength and balance between dominant foot (DF) and nondominant foot (non-DF) of individuals undergoing ligament stabilization surgery in the general population. Patients with records of preoperative evaluation, including isokinetic dynamometric strength evaluation, Y-balance test (YBT), and Foot and Ankle Outcome Score (FAOS), were included in the study. The DF was the preferred leg for accurately kicking a ball through a goal. Statistical analysis determined the differences between DF and non-DF and the correlations between muscle strength, balance, and FAOS. There was no statistically significant difference between DF and non-DF regarding evertor and invertor muscle strength (p=0.082-0.951). The YBT revealed no significant difference between the two groups (p=0.082-0.951). There was a significant correlation between the evertor peak torque and total work deficits at 30°/s (p=0.022), as well as the evertor peak torque deficit at 120°/s (p=0.048). No significant differences in muscle strength and balance were found between DF and non-DF in nonathletes with chronic ankle instability. Peroneal muscle strength deficit was associated with functional impairment. Tailored interventions are needed to address limb dominance and muscle strength deficits in CAI management.
我们的研究旨在检查在普通人群中接受韧带稳定手术的个体中，优势足（DF）和非优势足（非-DF）术前的力量和平衡差异。本研究纳入了有术前评估记录的患者，包括等速测力评估、Y 平衡测试（YBT）和足踝结局评分（FAOS）。DF 是指准确踢球过球门的首选腿。统计分析确定了 DF 和非-DF 之间的差异，以及肌肉力量、平衡和 FAOS 之间的相关性。DF 和非-DF 在外侧和内侧肌肉力量方面没有统计学差异（p=0.082-0.951）。YBT 显示两组之间没有显著差异（p=0.082-0.951）。在 30°/s 时，外侧峰值扭矩与总工作缺陷之间存在显著相关性（p=0.022），在 120°/s 时，外侧峰值扭矩缺陷与总工作缺陷之间存在显著相关性（p=0.048）。在慢性踝关节不稳定的非运动员中，DF 和非-DF 之间的肌肉力量和平衡没有显著差异。腓骨肌肉力量缺陷与功能障碍有关。在 CAI 管理中，需要有针对性的干预措施来解决肢体优势和肌肉力量缺陷的问题。
