Description
技术领域
本发明 涉及一种踝关节内翻诱发装置及测量腓骨长肌反应的方法。
背景技术
踝关节损伤在体育运动中非常常见，从损伤发生的关节位置来看，踝关节占了14%~15%。其中踝关节扭伤较为普遍，导致踝关节重复扭伤的主要原因之一是功能性踝关节不稳。目前，导致功能性踝关节不稳的原因还不确定。国外有研究认为，功能性不稳踝关节由于韧带组织的受伤，对关节囊内的机械性感受器包括关节感受器造成破坏，这将导致从外界干扰的输出信号到募集肌肉正确收缩的时间发生延迟，最终改变了关节稳定性，功能性踝关节不稳引起的本体感觉受损将导致腓骨长肌反应时延长。
目前，肌肉反应时已成为评价运动员神经肌肉功能状态非常重要的指标，尤其是反应时与肌纤维类型相关关系，已引起运动训练领域的高度重视[1]，神经肌肉反应活动是人体姿势控制能力研究的重要部分，尤其在身体突然失衡的应急姿势控制的研究中。对于反应时的研究，Konradsen, Raven和Karlsson et al，利用肌电图方法记录踝关节外翻时腓骨肌反应时，把从踝关节外翻到肌肉激发肌电达到一定数值这段时间称为腓骨肌反应时。肌肉反应时的测量往往需要精确的力量测定装置和肌电图检测技术，而且需要两种装置的同步连接以及相应的刺激装置，设备昂贵、实验设计复杂，不宜广泛应用。LiLi等人在2004年提出了一种测定肌肉反应时的新方法，此方法无需昂贵复杂的力学测试仪器及实验，但需进行不同频率的功率车蹬踏并配合肌电图以及需要复杂的演算和公式推算，跨学科的知识领域给研究人员带来了困扰。
近年来，我国在对踝关节稳定性起保护作用的腓骨长肌反应时测定方法的研究工作上有很多欠缺。为了解我国运动爱好者及运动员腓骨长肌的反应时间，建立我们自己的检测方法，为踝关节扭伤的防治和评定提供客观的理论依据，大大降低实验测试成本，我们研制出踝关节内翻诱发装置，并配以NORAXON表面肌电测试系统，对30例受试者进行了双侧腓骨长肌反应时的测定。
发明内容
为了弥补上述缺陷，本发明提供了一种测量腓骨长肌反应的方法检测方法，为踝关节扭伤的防治和评定提供客观的理论依据，大大降低实验测试成本，我们研制出踝关节内翻诱发装置，并配以NORAXON表面肌电测试系统。
本发明的技术方案是：一种踝关节内翻诱发装置，由箱体底板，箱体中间部和上部的矫正板组成，箱体底板与箱体中间部下表面连接，其中箱体中间部由四块侧板组成，板块之间均由螺杆连接，矫正板一端的下面并排设置有安装在圆柱直线导轨上的有四个外球面带座轴承，矫正板上面安装有条形铁块，箱体侧板上装有条形电磁铁。
本发明所述的矫正板的下落倾斜角度约为30°,矫正板在无重力下的下落时间为100ms。
本发明箱体底板上安装有220V转12V的交直流电源转换器，连接电线、插头及开关，所述的电源转换器与电磁铁连接。
本发明将踝关节内翻诱发装置的控制开关与安装NORAXON、MR3软件的电脑鼠标相连构成鼠标同步器，鼠标按键后启动软件同时启动无线发射模块，无线接收模块接收信号后启动内翻诱发装置，踝关节内翻诱发装置的条形电磁铁和条形铁板分离，踝关节形成内翻动作，与此同步，NORAXON表面肌电测试系统采集腓骨长肌保护性收缩产生的肌电信号，每块肌肉测定3次，计算平均数值，每次测定间隔3-5分钟。
本发明的有益效果是：(1)该方法涉及的自制内翻诱发装置方便实用，足底翻板翻转效果较好，主要的创新点为将踝关节内翻诱发装置的控制开关和鼠标相连构成鼠标控制器，可以利用鼠标远程控制，实现了机械测量翻板翻转和肌电信息采集的同步，成功确定了腓骨长肌反应时开始的时间。
(2)本发明应用试验预示，该踝内翻装置诱导的踝关节肌群尤其是腓骨长肌应急控制能有效应用于人体的神经肌肉反应时测量，评定神经肌肉反应速度能力。
(3）本发明对神经肌肉反应时测试，为踝关节扭伤的防治、评定，运动能力的评估提供了客观的理论依据。
附图说明
图1该测量方法涉及设备组成图。
图2为该测量方法的原理方框图。
图3为腓骨长肌反应时数据采集图。
具体实施方式
下面结合附图对本实施例做进一步的描述：
一种踝关节内翻诱发装置，由箱体底板1，箱体中间部和上部的矫正板2组成，箱体底板与箱体中间部下表面连接，其中箱体中间部由四块侧板3组成，板块之间均由螺杆连接，矫正板一端的下面并排设置有安装在圆柱直线导轨14上的有四个外球面带座轴承13，矫正板上面安装有条形铁块6，箱体侧板上装有条形电磁铁7。
本发明 所述的矫正板的下落倾斜角度为30°,矫正板在无重力下的下落时间为100ms。
本发明 箱体底板上安装有220V转12V的交直流电源转换器8，连接电线9、插头10及开关11，所述的电源转换器8与电磁铁连接。
本发明所述的电源转换器8通过远程控制装置12连接控制。
附图中的时刻4翻板开始下落，踝关节内翻始动，5为肌肉表面电信号超过安静状态下肌电值标准差（SD）三倍的时刻，4到5的时间即为测得的腓骨长肌反应时。时间单位为毫秒。每块肌肉测定3次，计算平均数值。为保证腿部肌肉适当放松休息，使所得数据准确、可靠，每次测定间隔3-5分钟。对于同一个受试者不同测试者进行设备操作，消除个体操作的差异性。
测试之前，在左右腿外侧的腓骨长肌的肌腹最突出的部位，酒精清洁皮肤，将电极片贴在所测肌的肌腹。
受试者测试前分别在双侧小腿的腓骨长肌肌腹最突出部位贴附表面肌电，贴附好表面肌电的受试者受试足站立在自制踝关节内翻诱发装置上，非受试足站在平衡木箱上。测试者在受试者不知情的情况下打开自制踝关节内翻诱发装置的开关（同时NORAXON MR3软件实时记录受试足内翻发生时的表面肌电信号），受试侧的踝关节突然遭受内翻应力，腓骨肌发生保护性收缩，从诱发装置倾斜瞬间出现的机械信号到矫正板下落造成内翻时所测腓骨长肌肌肉激发的肌电信号的起始点的时间即为腓骨长肌反应时（即图3中4到5的时间）。
