摘要
简介：慢性踝关节不稳（CAI）是一种由反复踝关节扭伤引起的慢性综合征，会导致持续的功能障碍：本研究旨在确定视觉干扰是否会影响慢性踝关节不稳定（CAI）患者和非慢性踝关节不稳定患者的静态和动态姿势控制，目的是全面了解视觉输入和姿势控制之间的相互作用：30 名 CAI 患者（21 名男性和 9 名女性，年龄 = 22.0 ± 1.8 岁，身高 = 174.4 ± 10.2 厘米，体重 = 72.5 ± 15.4 千克；坎伯兰踝关节不稳定工具（CAIT）评分 = 19.7 ± 1.8）和 29 名无 CAI 患者（24 名男性和 5 名女性，年龄 = 22.9 ± 1.6 岁，身高 = 172.8 ± 8.0 厘米，体重 = 69.0 ± 11.3 千克；CAIT 得分 = 29.0 ± 0.7）。在使用频闪眼镜模拟视觉干扰或无视觉干扰的两种情况下，对他们的静态和动态姿势控制能力进行了测量。静态姿势控制是在单肢站立时测量的，用足底压力中心（CoP）的均方根来表示；动态姿势控制是在 Y 平衡测试时测量的，用相对伸展距离来表示。双向混合方差分析（组间：CAI vs 非 CAI，组内：CAI vs 非 CAI，组间：CAI vs 非 CAI，组间：CAI vs 非 CAI结果和讨论：在前胸（AP）（p = 0.021，η2 p = 0.090）和内外侧（ML）（p < 0.001，η2 p = 0.208）方向，以及后内侧（PM）p = 0.023，η2 p = 0.088）和后外侧（PL）（p = 0.009，η2 p = 0.113）方向的相对到达距离。CAI患者在AP和ML方向的CoP-RMS显著增加，在PM和PL方向的相对到达距离显著减少，而在无CAI患者中则保持不变。CAI 患者的姿势控制很容易受到视觉干扰的影响，这凸显了视觉输入对这类人群保持稳定姿势的重要性。
Effects of visual disruption on static and dynamic postural control in people with and without chronic ankle instability.
Introduction: Chronic Ankle Instability (CAI) is a chronic syndrome resulting from repeated ankle sprains that lead to persistent dysfunction.the purpose of this study is to determine whether visual disruption could influence static and dynamic postural control in people with and without chronic ankle instability (CAI), with the objective of gaining a comprehensive understanding of the interactions between visual inputs and postural control.
Methods: Thirty people with CAI (21 males and 9 females, age = 22.0 ± 1.8 years, height = 174.4 ± 10.2 cm, body mass = 72.5 ± 15.4 kg; Cumberland Ankle Instability Tool (CAIT) score = 19.7 ± 1.8) and twenty-nine without CAI (24 males and 5 females, age = 22.9 ± 1.6 years, height = 172.8 ± 8.0 cm, body mass = 69.0 ± 11.3 kg; CAIT score = 29.0 ± 0.7) were recruited. Their static and dynamic postural control was measured in two conditions with or without visual disruption, simulated using stroboscopic glasses. Static postural control was measured during single-limb standing and represented by root mean square (RMS) of the plantar center of pressure (CoP), dynamic postural control was measured during a Y-balance test and represented by the relative reach distance. Two-way mixed ANOVA (between group: CAI vs non-CAI, within group: normal vision vs visual disruption) was used to analyze data.
Results and discussion: Significant interactions were detected in the CoP-RMS in the anteroposterior (AP) (p = 0.021, η2p = 0.090) and mediolateral (ML) (p < 0.001, η2p = 0.208) directions, and the relative reach distances in the posteromedial (PM) p = 0.023, η2p = 0.088) and posterolateral (PL) (p = 0.009, η2p = 0.113) directions, from normal vision to visual disruption. The CoP-RMS in the AP and ML directions significantly increased and the relative reach distances in the PM and PL directions significantly decreased in people with CAI while remaining unchanged in those without CAI. People with CAI are susceptible to visual disruption on postural control, highlighting the importance of visual input in maintaining stable posture in this population.
期刊介绍：
The translation of new discoveries in medicine to clinical routine has never been easy. During the second half of the last century, thanks to the progress in chemistry, biochemistry and pharmacology, we have seen the development and the application of a large number of drugs and devices aimed at the treatment of symptoms, blocking unwanted pathways and, in the case of infectious diseases, fighting the micro-organisms responsible. However, we are facing, today, a dramatic change in the therapeutic approach to pathologies and diseases. Indeed, the challenge of the present and the next decade is to fully restore the physiological status of the diseased organism and to completely regenerate tissue and organs when they are so seriously affected that treatments cannot be limited to the repression of symptoms or to the repair of damage. This is being made possible thanks to the major developments made in basic cell and molecular biology, including stem cell science, growth factor delivery, gene isolation and transfection, the advances in bioengineering and nanotechnology, including development of new biomaterials, biofabrication technologies and use of bioreactors, and the big improvements in diagnostic tools and imaging of cells, tissues and organs.
In today`s world, an enhancement of communication between multidisciplinary experts, together with the promotion of joint projects and close collaborations among scientists, engineers, industry people, regulatory agencies and physicians are absolute requirements for the success of any attempt to develop and clinically apply a new biological therapy or an innovative device involving the collective use of biomaterials, cells and/or bioactive molecules. “Frontiers in Bioengineering and Biotechnology” aspires to be a forum for all people involved in the process by bridging the gap too often existing between a discovery in the basic sciences and its clinical application.
