Proprioception is essential for neuromuscular control in relation to sport injury and performance. The effect of landing heights and loads on ankle inversion proprioceptive performance in individuals with or without chronic ankle instability (CAI) may be important but are still unclear. Forty-three participants (21 CAI and 22 non-CAI) volunteered for this study. The Ankle Inversion Discrimination Apparatus for Landing (AIDAL), with one foot landing on a horizontal surface and the test foot landing on an angled surface (10°, 12°, 14°, 16°), was utilized to assess ankle proprioception during landing. All participants performed the task from a landing height of 10 cm and 20 cm with 100% and 110% body weight loading. The four testing conditions were randomized. A repeated measures ANOVA was used for data analysis. The result showed that individuals with CAI performed significantly worse across the four testing conditions (p = 0.018). In addition, an increased landing height (p = 0.010), not loading (p > 0.05), significantly impaired ankle inversion discrimination sensitivity. In conclusion, compared to non-CAI, individuals with CAI showed significantly worse ankle inversion proprioceptive performance during landing. An increased landing height, not loading, resulted in decreased ankle proprioceptive sensitivity. These findings suggest that landing from a higher platform may increase the uncertainty of judging ankle positions in space, which may increase the risk of ankle injury.
本体感觉对于与运动损伤和运动表现相关的神经肌肉控制至关重要。着陆高度和负荷对患有或未患有慢性踝关节不稳（CAI）的个体的踝关节内翻本体感觉表现的影响可能很重要，但仍不清楚。43名参与者（21名患有CAI和22名未患有CAI）自愿参加了这项研究。使用着陆时踝关节内翻辨别装置（AIDAL），一只脚落在水平面上，测试脚落在倾斜表面（10°、12°、14°、16°）上，以评估着陆期间的踝关节本体感觉。所有参与者在10厘米和20厘米的着陆高度下，分别以100%和110%的体重负荷执行任务。这四种测试条件是随机的。数据分析采用重复测量方差分析。结果表明，患有CAI的个体在四种测试条件下的表现明显更差（p = 0.018）。此外，着陆高度增加（p = 0.010）而非负荷增加（p > 0.05）会显著损害踝关节内翻辨别敏感性。总之，与未患有CAI的个体相比，患有CAI的个体在着陆期间的踝关节内翻本体感觉表现明显更差。着陆高度增加而非负荷增加导致踝关节本体感觉敏感性降低。这些发现表明，从更高的平台着陆可能会增加判断空间中踝关节位置的不确定性，这可能会增加踝关节受伤的风险。
