BACKGROUND
Motor control evaluation in subjects with functional ankle instability is questionable when both ankles of the same subject are compared (affected vs non-affected).
OBJECTIVE
To compare the postural control and reaction time of ankle muscles among: basketball players with FAI (instability group), basketball players without FAI (non-instability group) and healthy non-basketball-playing participants (control group).
DESIGN
Case-control study.
SETTING
Laboratory.
PARTICIPANTS
Instability (n = 10), non-instability (n = 10), and control groups (n = 11).
MAIN OUTCOME MEASURES
Centre of pressure variables (area, velocity and sway) were measured with a force platform. Reaction time of ankle muscles was measured via electromyography.
RESULTS
A one-way ANOVA demonstrated that there were significant differences between the instability and non-instability groups in the fibularis longus (p < 0.001), fibularis brevis (p = 0.031) and tibialis anterior (p = 0.049) muscles. Repeated-measures ANOVA and post hoc analysis determined significant differences for the area between the instability and non-instability groups (p = 0.001).
CONCLUSION
Basketball players with FAI have reduced postural control and longer reaction time of the fibularis and tibialis anterior muscles.
背景
当比较同一受试者的双侧脚踝（患侧与未患侧）时，对功能性踝关节不稳受试者进行运动控制评估存在疑问。
目的
比较以下三组人群的姿势控制和踝关节肌肉反应时间：患有功能性踝关节不稳的篮球运动员（不稳组）、不患有功能性踝关节不稳的篮球运动员（非不稳组）和健康的非篮球运动参与者（对照组）。
设计
病例对照研究。
设置
实验室。
参与者
不稳组（n = 10）、非不稳组（n = 10）和对照组（n = 11）。
主要观察指标
使用测力平台测量压力中心变量（面积、速度和摆动）。通过肌电图测量踝关节肌肉的反应时间。
结果
单向方差分析表明，不稳组和非不稳组在腓骨长肌（p < 0.001）、腓骨短肌（p = 0.031）和胫骨前肌（p = 0.049）方面存在显著差异。重复测量方差分析和事后分析确定了不稳组和非不稳组之间在面积方面存在显著差异（p = 0.001）。
结论
患有功能性踝关节不稳的篮球运动员姿势控制能力下降，腓骨肌和胫骨前肌的反应时间延长。
