对于年轻人来说，平衡对于参与体育活动至关重要，但下肢受伤后往往会被破坏。单肢平衡 (SLB)、Y 平衡 (YBT) 和单肢跳跃和平衡 (SLHB) 测试等临床结果测量通常用于量化受伤后的平衡能力。考虑到不同任务的需求不同，此类结果度量很可能提供有用的信息，尽管是特定于任务的信息。但他们的独立性以及在多大程度上有助于理解多重贡献者的平衡尚不清楚。因此，本研究的目的是调查这些措施之间的关联，因为它们与平衡的不同贡献者相关。 37 名休闲活跃的年轻人完成了包括垂直弹跳、YBT、SLB、SLHB 和新的下肢灵活性测试在内的测量。主成分分析表明，这些结果测量可以被认为是量化力量、多关节协调和感觉运动处理对平衡的贡献。我们的结果挑战了使用单一结果测量来量化平衡等日常功能的自然多维机制的做法。这种对平衡的多个因素的多维方法和解释可能会带来更有效、更专业的训练和康复方案。
For young adults, balance is essential for participation in physical activities but is often disrupted following lower extremity injury. Clinical outcome measures such as single limb balance (SLB), Y-balance (YBT), and the single limb hop and balance (SLHB) tests are commonly used to quantify balance ability following injury. Given the varying demands across tasks, it is likely that such outcome measures provide useful, although task-specific, information. But the extent to which they are independent and contribute to understanding the multiple contributors to balance is not clear. Therefore, the purpose of this study was to investigate the associations among these measures as they relate to the different contributors to balance. Thirty-seven recreationally active young adults completed measures including Vertical Jump, YBT, SLB, SLHB, and the new Lower Extremity Dexterity test. Principal components analysis revealed that these outcome measures could be thought of as quantifying the strength, multijoint coordination, and sensorimotor processing contributors to balance. Our results challenge the practice of using a single outcome measure to quantify the naturally multidimensional mechanisms for everyday functions such as balance. This multidimensional approach to, and interpretation of, multiple contributors to balance may lead to more effective, specialized training and rehabilitation regimens.
