踝关节本体感受信息由中枢神经系统整合，以产生和调节肌肉收缩，从而维持站立平衡。本研究评估了踝关节本体感觉与成年期平衡、活动和身体功能的客观和自我报告指标之间的关系。本研究纳入了来自美国巴尔的摩老龄化纵向研究（BLSA）人群队列的790名参与者（年龄范围24-97岁，362名女性），这些参与者在2010年至2014年期间完成了踝关节本体感觉评估。结果指标包括踝关节本体感觉，测量为被动运动感知阈值（TPPM）;单腿站立时间;站立平衡的感知困难;通常，最快和窄路径步态速度;步行指数;短体能电池评分;和自我报告的活动限制由于害怕跌倒。描述性变量包括年龄、性别、体重指数、教育、力量和认知。在一般线性模型（GLM）中进行协方差分析（ANCOVA）或多项逻辑回归分析（如适用），以检验以下假设：即使在调整相关协变量后，根据TPPM五分位数，平衡、移动性和身体功能也存在显著差异。那些TPPM >2.2度的人一直表现出平衡，移动性和身体功能差。然而，随着挑战性的增加（单腿站立、最快步行速度和SPPB），TPPM >1.4度与明显较差的表现相关。总之，踝关节本体感觉敏锐度与平衡、移动性和身体功能的客观和自我报告指标之间存在整体分级关系。然而，与实质性下降或无法执行相关的截断本体感受敏锐度可能取决于诱导的挑战。
Ankle proprioceptive information is integrated by the central nervous system to generate and modulate muscle contractions for maintaining standing balance. This study evaluated the association of ankle joint proprioception with objective and self-report measures of balance, mobility, and physical function across the adult life span. Seven hundred and ninety participants (age range 24-97 years, 362 women) who completed ankle proprioception assessment between 2010 and 2014 were included in the present study from the population-based cohort of the Baltimore Longitudinal Study of Aging (BLSA), USA. Outcome measures included ankle joint proprioception measured as threshold for perception of passive movement (TPPM); single leg stance time; perceived difficulty for standing balance; usual, fastest, and narrow-path gait speed; walking index; short physical performance battery score; and self-reported activity restriction due to fear of falling. Descriptive variables included age, sex, body mass index, education, strength, and cognition. Analyses of covariance (ANCOVA) in general linear model (GLM) or multinomial logistic regression analyses were performed, as appropriate, to test the hypothesis that balance, mobility, and physical function were significantly different according to TPPM quintiles even after adjusting for relevant covariates. Those with TPPM >2.2 degrees consistently demonstrated poor balance, mobility, and physical function. However, with increase in challenge (single leg stance, fastest walking speed, and SPPB), TPPM >1.4 degrees was associated with significantly worse performance. In conclusion, ankle proprioceptive acuity has an overall graded relationship with objective and self-report measures of balance, mobility, and physical function. However, the cutoff proprioceptive acuity associated with substantial decline or inability to perform could depend on the challenge induced.
