摘要:


文题释义
足外展角度:又称足偏角,是指足跟到第二跖骨连线与前进方向的夹角。
慢性踝关节不稳:踝关节扭伤发生后,很大一部分受伤者会出现踝关节反复扭伤、疼痛、持续肿胀、“脚打软”、关节不稳等后遗症状,即慢性踝关节不稳。慢性踝关节不稳通常分为功能性踝关节不稳和机械性踝关节不稳,前者又被称为感知性不稳,在慢性踝关节不稳中约占35%;后者则指由于关节软骨、韧带、关节囊病变和周围组织损伤而导致的解剖结构不稳。

摘要
背景:慢性踝关节不稳者在着地时易发生踝关节内翻扭伤,适度增大着地时足外展角度有助于减少踝关节内翻扭伤的发生,但尚无研究直接论证。
目的:探讨着地时增加足外展角度对有无慢性踝关节不稳者着地过程中踝内翻角度、角度峰值时刻及角速度峰值的影响。
方法:共招募了60名受试者,其中慢性踝关节不稳者30名,非慢性踝关节不稳者30名。使用模拟扭伤装置进行下落跳测试,该装置中的活动平台可向前翻转24°、向内侧翻转15°,从而模拟踝关节内翻扭伤时的足部位置。受试者需要在两种着地状态下进行下落跳测试,即自然着地和外展着地,后者的足外展角度更大,约为前者的150%以上。使用12摄像头三维红外动作捕捉系统记录运动学数据,采用双因素重复测量方差分析和Spearman相关分析进行数据分析。
结果与结论:①下落跳时的内翻角度峰值(P < 0.001,η2 p=0.270)、内翻角速度峰值(P=0.015,η2 p=0.098)和内翻角度峰值时刻(P < 0.001,η2 p=0.260)均存在显著的状态主效应;内翻角速度峰值存在显著的组别主效应(P=0.029,η2 p=0.080);②慢性踝关节不稳组与非慢性踝关节不稳组受试者着地时的足外展角度与踝内翻角度峰值(P=0.021,r=-0.310;P=0.042,r=-0.278)、内翻角度峰值时刻(P=0.018,r=-0.312;P=0.021,r=-0.309)均存在显著的负相关关系;慢性踝关节不稳组受试者着地时的足外展角度与内翻角速度峰值(P=0.021,r=-0.312)之间也存在显著的负相关关系;③提示增加着地时的足外展角度可以减小慢性踝关节不稳及非慢性踝关节不稳人群着地过程中的内翻角度峰值、内翻角速度峰值,提前内翻角度峰值时刻,从而降低踝内翻扭伤的风险。

Abstract: BACKGROUND: Individuals with chronic ankle instability are prone to inversion ankle sprains during landing. Moderately increasing the foot toe-out angle during landing may reduce the occurrence of inversion ankle sprains, but no studies have directly demonstrated this effect. 
OBJECTIVE: To explore the effect of increased toe-out angle during landing on the peak inversion angle, peak angular velocity, and the time to peak inversion among individuals with and without chronic ankle instability. 
METHODS: A total of 60 participants were recruited for this study, including 30 individuals with chronic ankle instability and 30 without chronic ankle instability. The study utilized a simulated sprain apparatus for drop-landing tests, featuring a platform that could tilt forward by 24° and inward by 15°, thus simulating the foot position during an ankle inversion sprain. Participants were required to perform drop-landing tests under two landing conditions: natural landing and toe-out landing, with the latter involving a greater foot toe-out angle, over 150% more than the former. Kinematic data of participants were recorded using a 12-camera three-dimensional motion capture system. Data analysis was conducted using two-way repeated measures analysis of variance and Spearman correlation analysis.

RESULTS AND CONCLUSION: (1) Significant main effects of condition were found for peak inversion angle during drop-landing (P < 0.001, η2 p=0.270), peak inversion velocity (P=0.015, η2 p=0.098), and peak inversion time (P < 0.001, η2 p=0.260); a significant main effect of group was found for peak inversion velocity (P=0.029, η2 p=0.080). (2) There were significant negative correlations between the foot toe-out angle at landing and the peak ankle inversion angle (P=0.021, r=-0.310; P=0.042, r=-0.278) as well as the peak inversion time (P=0.018, r=-0.312; P=0.021, r=-0.309) in both chronic ankle instability and non-chronic ankle instability groups. Moreover, a significant negative correlation was also found between the foot toe-out angle and peak inversion velocity in the chronic ankle instability group (P=0.021, r=-0.312). (3) It is indicated that increasing the foot toe-out angle at landing can reduce the peak inversion angle, peak inversion velocity, and the peak inversion time during landing in patients with chronic ankle instability and non-chronic ankle instability, thereby decreasing the risk of ankle inversion sprains.
