摘要
目的 明确功能性踝关节不稳(FAI)患者单脚静立平衡能力与踝关节肌力和本体位置觉的关系.方法 2023年3月至5月,在河北师范大学招募FAI患者44例,采用等速测力仪测量踝跖屈、背屈、内翻和外翻的等速向心肌力(60°/s和180°/s),以及位置觉,采用三维测力台测量睁眼和闭眼状态下单脚静立平衡时压力中心(COP)的晃动距离和包络面积.结果 180°/s下踝外翻最大等速力矩与闭眼单脚静立时COP前后方向晃动距离相关(r =-0.378,P<0.05).结论 踝关节快速外翻肌力与单脚静立平衡能力有关,可能有助于评价或干预FAI患者踝关节功能.
Abstract
Objective To analyze the relationship of the static single-leg stance balance with ankle muscles strength and position sense in individuals with functional ankle instability(FAI).Methods From March to May,2023,44 FAI individuals were recruited in Hebei Normal University,and the maximum isokinetic muscle strength(60°/s and 180°/s)and position sense as ankle flexion,extension,inversion and ever-sion were measured using isokinetic dynamometer;while the center of pressure(COP)sway distance and enve-lope area were measured as static single-leg stance with eyes open or closed using three-dimensional force plate.Results The maximum isokinetic torque as ankle eversion at 180°/s correlated with the COP anterior-posterior sway dis-tance with eyes closed(r =-0.378,P<0.05).Conclusion Explosive ankle eversion strength is related with the balance in static single-leg stance,which may help to evaluate and intervent the ankle function of FAI individuals.
