目的：探讨慢性踝关节不稳定（CAI）患者的足底皮肤感觉和姿势控制是否存在差异。设计：病例对照。设置：实验室。对象：10名CAI受试者和10名无踝关节扭伤史的受试者参与研究。干预：使用Semmes-Weinstein单丝（SWM）在足部足底面的3个部位（足跟、第五跖骨基底和第一跖骨头）评价轻触。使用平衡误差评分系统（BESS）的单腿稳固和泡沫条件以及在力板上睁眼和闭眼静态姿势控制期间评估姿势控制。主要结果测量：对每名受试者的Semmes-Weinstein单丝检测阈值、BESS错误率、前后（AP）和内外方向的最小边界时间（TTB）平均值（TTB-平均值）和最小边界时间标准差（TTB-标准差）进行评价。结果：CAI受试者在足跟（P = 0.009）、第一跖骨头（P = 0.01）和第五跖骨基底（P < 0.001）处的SWM检测阈值增加，在BESS固定（P = 0.04）和泡沫（P = 0.001）条件下以及睁眼TTB平均AP（P = 0.007）和TTB SD AP（P = 0.02）时的姿势控制缺陷。当合并组时，第五跖骨检测阈值的基底与睁眼TTB平均AP之间观察到中度负相关（r =-0.50; P = 0.03）。结论：轻度触觉和姿势控制缺陷在CAI患者中观察到。轻触第五跖骨底部和睁眼TTB平均AP之间的相关性表明，这些措施之间可能存在相关关系。临床相关性：CAI患者表现出足部跖面的轻触缺陷。第五跖骨感觉的基础和TTB平均AP之间的关系可以提供一个起点，链接足底皮肤感觉缺陷的感觉运动功能的其他方面的变化。
Objective:To determine if plantar cutaneous sensation and postural control differ between individuals with and without chronic ankle instability (CAI). Design:Case–control. Setting:Laboratory. Participants:Ten subjects with CAI and 10 subjects with no ankle sprain history participated. Interventions:Light touch was evaluated at 3 sites (heel, base of fifth metatarsal, and head of first metatarsal) on the plantar aspect of the foot using Semmes–Weinstein Monofilaments (SWMs). Postural control was assessed using the single leg firm and foam conditions of the Balance Error Scoring System (BESS) and during eyes open and eyes closed static postural control on a force plate. Main Outcome Measures:Semmes–Weinstein Monofilament detection thresholds, BESS errors, and the mean of time-to-boundary (TTB) minima (TTB-mean) and the SD of TTB minima (TTB-SD) in the anterior–posterior (AP) and medial–lateral directions were evaluated for each subject. Results:Subjects with CAI demonstrated increased SWM detection thresholds at the heel (P = 0.009), head of the first (P = 0.01), and base of the fifth metatarsal (P < 0.001) and postural control deficits on the BESS firm (P = 0.04) and foam (P = 0.001) conditions and with eyes open TTB-mean AP (P = 0.007) and TTB-SD AP (P = 0.02). When combining groups, a negative moderate correlation was observed between the base of the fifth metatarsal detection threshold and eyes open TTB-mean AP (r = −0.50; P = 0.03). Conclusions:Light touch and postural control deficits were observed in individuals with CAI. The correlation between light touch over the base of the fifth metatarsal and eyes open TTB-mean AP suggests that there may be a relevant relationship between these measures. Clinical Relevance:Individuals with CAI demonstrated deficits in light touch over the plantar aspect of the foot. The relationship between base of the fifth metatarsal sensation and TTB-mean AP may provide a starting point to link plantar cutaneous sensory deficits to changes in other aspects of sensorimotor function.
