Sports rehabilitation professionals often prescribe unstable objects for balance training. Unfortunately, there is a lack of measurement of balance confidence when incorporating these objects. Currently, there is no consensus on the optimal balance confidence measure or proposed progression of unstable objects. Understanding the influence of balance confidence on task performance using unstable objects may help professionals better prescribe a balance training program.
The primary purpose of this investigation was to explore the correlation between anticipated and actual balance confidence on different unstable objects during static double leg and single leg stance. The secondary purpose was to explore the correlation between anticipated and actual unstable object difficulty rankings.
Repeated measure observational, controlled trial.
Sixty-five active, healthy adults (M = 35, F = 30) (mean age = 24.38 ± 3.56) underwent two testing sessions. During session one, participants took an online survey, rating their anticipated balance confidence after observing images of different unstable objects. During session two, participants stood on each unstable object under two conditions (static double leg stance and single leg stance) and rated their actual balance confidence. The main outcome measure was an ordinal balance confidence score adapted from the activities-specific balance confidence scale. Statistical analysis included subject demographic calculations and appropriate non-parametric tests.
For the double leg stance and single leg stance conditions, there was a very strong correlation between anticipated and actual balance confidence scores on the stable surface (ρ = 1.0, p = <.001). There was a weak correlation between scores for foam pad, air-filled discs, Bosu® (dome up), Bosu® (dome down), and wobble board for both conditions. For unstable object rankings, there was a very strong correlation between scores (ρ=1.0, p = <.001). The objects were ranked by perceived difficulty as follows: Level 1 (easy)- ground, Level 2- foam pad, Level 3- air-filled discs, Level 4- Bosu®, and Level 5 (difficult)- wobble board.
Study findings suggest that actual measures of balance confidence may provide insight into a patient's confidence level and may help with prescribing and progressing their program. The suggested unstable object difficulty rankings may help professionals better match the objects to their patients to produce optimal outcomes.

运动康复专业人员经常为平衡训练开具不稳定物体。不幸的是，在纳入这些物体时缺乏对平衡信心的测量。目前，对于最佳平衡信心测量方法或不稳定物体的建议进阶方式尚无共识。了解使用不稳定物体时平衡信心对任务表现的影响可能有助于专业人员更好地制定平衡训练计划。
本研究的主要目的是探讨在静态双腿和单腿站立时，不同不稳定物体上预期平衡信心与实际平衡信心之间的相关性。次要目的是探讨预期和实际不稳定物体难度排名之间的相关性。
重复测量观察性对照试验。
65名活跃、健康的成年人（男性35名，女性30名）（平均年龄 = 24.38 ± 3.56）接受了两次测试。在第一次测试中，参与者进行了一项在线调查，在观察不同不稳定物体的图像后对他们预期的平衡信心进行评分。在第二次测试中，参与者在两种条件下（静态双腿站立和单腿站立）站在每个不稳定物体上，并对他们的实际平衡信心进行评分。主要结果测量是根据特定活动平衡信心量表改编的有序平衡信心得分。统计分析包括受试者人口统计学计算和适当的非参数检验。
对于双腿站立和单腿站立条件，在稳定表面上预期平衡信心得分与实际平衡信心得分之间存在非常强的相关性（ρ = 1.0，p = <.001）。在两种条件下，泡沫垫、充气圆盘、波速球（圆顶向上）、波速球（圆顶向下）和摇摆板的得分之间存在弱相关性。对于不稳定物体排名，得分之间存在非常强的相关性（ρ = 1.0，p = <.001）。这些物体按感知难度排名如下：第1级（容易） - 地面，第2级 - 泡沫垫，第3级 - 充气圆盘，第4级 - 波速球，第5级（困难） - 摇摆板。
研究结果表明，平衡信心的实际测量可能有助于深入了解患者的信心水平，并可能有助于制定和推进他们的训练计划。建议的不稳定物体难度排名可能有助于专业人员更好地将物体与患者匹配，以产生最佳效果。
