Individuals with chronic ankle instability (CAI) may experience recurrent ankle sprains and symptoms during daily activities such as stair descent, where the associated proprioceptive deficit is largely unevaluated.
To evaluate the reliability and validity of an ankle inversion discrimination apparatus for stair descent, and examine whether proprioceptive scores from this apparatus are associated with patient-reported symptoms.
Cross-sectional study.
Sixty-six participants volunteered in this study. The ankle inversion discrimination apparatus was purpose-built to assess ankle proprioception across four positions of ankle inversion (10°, 12°, 14°, and 16°) during stair descent. The Area Under the Receiver Operating Curve (AUC) was employed as the ankle proprioceptive discrimination score.
Test-retest reliability ICC (3,1) for the whole group was 0.825, with 0.747 for the non-CAI group (95%CI = 0.331-0.920) and 0.701 for CAI (95%CI = 0.242-0.904). The CAI group performed at a significantly lower level than non-CAI on the ankle inversion discrimination apparatus for stair descent assessment (0.769 ± 0.034 vs. 0.830 ± 0.035, F = 33.786, p < 0.001). CAIT scores were strongly and significantly correlated with scores from this apparatus (Spearman's rho = 0.730, p < 0.001).
The ankle inversion discrimination apparatus for stair descent is reliable and valid for assessing task-specific ankle proprioceptive impairments in CAI. The strong and significant relationship found between ankle proprioception during stair descent and the severity of CAI suggests that rehabilitation programs focusing on deficits in ankle inversion proprioception during stair descent may improve self-reported instability in CAI.
慢性踝关节不稳（CAI）患者在诸如下楼梯等日常活动中可能会反复出现踝关节扭伤及症状，而相关的本体感觉缺陷在很大程度上未得到评估。
评估一种用于下楼梯的踝关节内翻辨别装置的可靠性和有效性，并检查该装置得出的本体感觉评分是否与患者报告的症状相关。
横断面研究。
66名参与者自愿参加本研究。该踝关节内翻辨别装置是专门设计用于评估下楼梯过程中踝关节在四个内翻位置（10°、12°、14°和16°）的本体感觉。采用受试者工作特征曲线下面积（AUC）作为踝关节本体感觉辨别评分。
整个组的重测信度ICC（3,1）为0.825，非CAI组为0.747（95%CI = 0.331 - 0.920），CAI组为0.701（95%CI = 0.242 - 0.904）。在用于下楼梯评估的踝关节内翻辨别装置上，CAI组的表现显著低于非CAI组（0.769 ± 0.034 vs. 0.830 ± 0.035，F = 33.786，p < 0.001）。CAI严重程度评分（CAIT）与该装置的评分呈强且显著的相关性（Spearman相关系数rho = 0.730，p < 0.001）。
用于下楼梯的踝关节内翻辨别装置在评估CAI中特定任务的踝关节本体感觉障碍方面是可靠且有效的。在下楼梯过程中踝关节本体感觉与CAI严重程度之间发现的强且显著的关系表明，针对下楼梯过程中踝关节内翻本体感觉缺陷的康复计划可能会改善CAI患者自我报告的不稳情况。
