Most clinicians use the Beighton score to assess generalized joint hypermobility (GJH) when deciding on the treatment of chronic lateral ankle instability (CLAI). The purpose of the study was to evaluate anterior talofibular ligament (ATFL) status by ultrasound and correlate these values with Beighton scores and the manual anterior drawer test (ADT).
The participants were divided into two groups, those without GJH (24 ankles) and with GJH (20 ankles). For the investigation of ATFL, resting and stress ultrasonography was performed to assess the length, height (degree of loosening) and thickness. Beighton scores, manual ADT grades and ultrasound parameters of participants with and without GJH were compared. The correlation coefficients among those values were analyzed.
The mean ATFL length, resting height, stress height and mean difference in height between resting and stress ATFL were all significantly different between the two groups (P < .05). The resting and stress ATFL length, height, and difference in height between resting and stress ATFL showed a positive linear relationship with Beighton scores and manual ADT grades (P < .05).
The ATFL stress ultrasound parameters showed significant differences between participants with high and low Beighton scores and were correlated with Beighton scores and manual ADT grades.

大多数临床医生在决定慢性外侧踝关节不稳定（CLAI）的治疗方案时，会使用 Beighton 评分来评估全身性关节过度活动（GJH）。本研究的目的是通过超声评估距腓前韧带（ATFL）的状态，并将这些值与 Beighton 评分和手动前抽屉试验（ADT）相关联。
参与者被分为两组，一组无 GJH（24 个踝关节），一组有 GJH（20 个踝关节）。为了研究 ATFL，进行了静息和应变成像，以评估长度、高度（松动程度）和厚度。比较了有无 GJH 的参与者的 Beighton 评分、手动 ADT 分级和超声参数。分析了这些值之间的相关系数。
两组间 ATFL 长度、静息高度、应激发度和静息与应激发度 ATFL 高度差值均有显著差异（P <.05）。静息和应激发度 ATFL 长度、高度和静息与应激发度 ATFL 高度差值与 Beighton 评分和手动 ADT 分级呈正线性关系（P <.05）。
ATFL 应变成像参数在 Beighton 评分高和低的参与者之间存在显著差异，与 Beighton 评分和手动 ADT 分级相关。
横断面队列研究；证据等级 IV。
