Description

一种地表步态及平衡检测装置
技术领域
本发明涉及人体步态与平衡检测装置领域,具体涉及一种地表步态与平衡检测装置设计及使用方法。
背景技术
老年人、中风患者、帕金森症患者是现社会一个庞大的群体,身体活动能力有限,平衡能力存在一定的不足,严重的甚至威胁到人身安全。地表步态检测可以准确评估人体的平衡能力,为受试者人身安全给出提前预警。对于存在平衡问题的人群,主动的交互式平衡训练可以更好地锻炼其人体平衡能力,有效提高身体的平衡性。对步态患者而言,细微的脚步不协调和步态姿势不正确很难被医生及自身发现,一旦不及时纠正,这些错误很可能成为一种习惯,且很难再次纠正,使其存在跌倒等风险。
人体步态是大范围的生物特征,是人体结构与功能、心理活动、运动系统以及行为在行走时的外在表现。与人脸相比,步态特征相对容易获取,可高效地实现准确人体特征识别。
本专利是通过测量步距、步速、步频和重心轨迹等数据来判断人体步态及平衡情况,与通过卷尺、秒表、量角器等测量工具及步行过程中所留下的脚印作为测量依据的传统测量方法相比,检测效率高,准确性好。
现有的步态及平衡测试器材结构复杂,占用空间大,成本高昂,且不能同时进行人体步态及平衡评测、人体步态识别、交互人体步态及平衡训练。因此,有必要设计一种结构简单,使用方便,节约空间,成本低廉,可以快速准确地获取步态数据,具有多种用途的地表步态及平衡测试装置。本装置可以实现大范围的人体特征识别(如性别、年龄等),也可对受试者的步态及平衡状况进行评估。此外,本装置还设计有适合人体步态及平衡训练的虚拟现实游戏,引导患者完成步态及平衡训练活动,提高患者康复过程的趣味性,有助于缩短人体康复训练周期。
因此,本发明针对现有步态及平衡检测技术的不足,发明了一种地表步态及平衡检测装置。

本发明的工作原理为:在装置组装完成后,受试者站在步态检测踏板1上。在医师指导下完成步态动作,或根据unity3D虚拟游戏场景中指定的任务完成相应步态动作,压力传感装置2实时将压力信号通过数据连接线3传输给数据采集模块4,同时指令控制模块6对步态关节角度/速度等数据进行采集,数据采集模块4及指令控制模块6所采集到的全部数据通过串口通信传输给智能终端模块5,智能终端模块5对采集到的这些数据进行存储、处理、分析及识别,并将结果显示在显示屏上。
所述的支撑架7是由两条长短相同的支撑杆组成,两支撑杆中部由铰接装置9连接,铰接装置9具有0~ 90°的旋转自由度,通过其顺时针/逆时针旋转可以实现压力传感模块的拆装。
所述的指令控制模块6为Kinect体感摄像机,通过与智能终端5相结合,实现实时人体步态显示与平衡分析。患者根据Unity3D设计适合人体步态训练的虚拟仿真游戏任务,完成相应的步态动作,提高患者步态及平衡训练的趣味性。
步态检测踏板是由钢化玻璃板定制而成,钢化玻璃的硬度系数高,可满足受试者完成多种不同的步态任务的要求。
采用本发明提供的技术方案,与已有的公知技术相比,具有如下有益效果:(1)本发明的一种地表步态及平衡检测装置,结构简单,设计合理新颖,可快速准确地获取受试者的地表步态及平衡信息,如步距、步速、步频和重心轨迹等。
