目的:探讨佩戴不同类型踝关节护具对功能性踝关节不稳者静态姿势稳定性的影响.方法:选取10名男性单侧功能性踝关节不稳者,利用FlexiForce压力感受系统控制佩戴弹性护具时的踝压,采用WIN-POD系统分别测量受试者患侧无护具、佩戴弹性护具、佩戴半刚性护具时的静态姿势稳定性.结果:(1)睁眼状态下,佩戴弹性护具和半刚性护具时COP动摇各指标与无护具时相比差异均无统计学意义(P＞0.05).与半刚性护具相比,佩戴弹性护具时X轴平均摆幅显著增大(P＜0.05).(2)闭眼状态下,佩戴弹性护具和半刚性护具时COP动摇各指标与无护具时相比差异均无统计学意义(P＞0.05);佩戴弹性护具与半刚性护具相比,各指标间差异也无统计学意义(P＞0.05).结论:佩戴弹性护具和半刚性护具不影响功能性踝关节不稳者的静态姿势稳定性,但佩戴半刚性护具时的静态姿势稳定性要好于佩戴弹性护具.“,”Objective To study the effects of different types of ankle brace on human body static postural stability.Method Ten male subjects with unilateral functional ankle instability (FAI)were enrolled in the study.The FlexiForce pressure control system was used to control the pressure on the ankles when wearing the soft brace.The static postural stability without braces as well as with soft and semi-rigid braces was measured using WIN-POD system.Results (1)In eye-open testing,no significant difference was found in indexes of COP sway between wearing or not wearing braces (P＞0.05).Compared with wearing semi-rigid brace,significant increase was observed in the average X dev when wearing soft braces (P＜0.05).(2)In eye-close testing,no significant differences were found in COP sway either wearing braces or not,as well as wearing different braces.Conclusion Wearing soft and semi-rigid brace had no effects on the static postural stability of FAI patients.But the static balance ability of wearing semi-rigid braces is better than that of wearing soft braces.
