Abstract

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.

长腓骨肌反应时间变长和篮球运动员踝关节功能不稳的姿势控制减少:一项初步研究

背景:当对同一受试者的两个脚踝(受影响与未受影响)进行比较时，功能性踝关节不稳定受试者的运动控制评估是值得怀疑的。目的比较篮球运动员有足部损伤(不稳定组)、无足部损伤(不稳定组)和健康非篮球运动员(对照组)踝关节肌肉的姿势控制和反应时间。不稳定组(n = 10)、非不稳定组(n = 10)和对照组(n = 11)。主要结果测量用力平台测量压力变量中心(面积、速度和摆动)。通过肌电图测量踝关节肌肉的反应时间。结果单因素方差分析显示，不稳定组与非不稳定组腓骨长肌的差异有统计学意义(p <0.001)，腓骨短肌(p = 0.031)和胫前肌(p = 0.049)。重复测量方差分析和事后分析确定了不稳定组和非不稳定组之间面积的显著差异(p = 0.001)。结论FAI篮球运动员的姿势控制能力下降，腓骨和胫骨前肌反应时间延长。

期刊介绍： Physical Therapy in Sport is an international peer-reviewed journal that provides a forum for the publication of research and clinical practice material relevant to the healthcare professions involved in sports and exercise medicine, and rehabilitation. The journal publishes material that is indispensable for day-to-day practice and continuing professional development. Physical Therapy in Sport covers topics dealing with the diagnosis, treatment, and prevention of injuries, as well as more general areas of sports and exercise medicine and related sports science. The journal publishes original research, case studies, reviews, masterclasses, papers on clinical approaches, and book reviews, as well as occasional reports from conferences. Papers are double-blind peer-reviewed by our international advisory board and other international experts, and submissions from a broad range of disciplines are actively encouraged.
