摘要:
大多数的脑卒中患者在下肢运动方面有障碍,给其生活带来了极大的不便,进行及时有效的康复训练是恢复下肢运动功能的关键。传统的下肢康复训练过程中重复性高,患者的参与度低和互动性差。为了解决该问题,本研究设计了一种基于虚拟场景的下肢康复训练系统。该系统实现了结合虚拟现实技术进行下肢康复训练和评估,采集和处理足底压力数据,控制虚拟场景中虚拟元素,显示训练的时间、得分和训练过程中足底压力的最大值、平均值。该系统由下位机硬件和上位机软件构成。硬件系统包括力传感模块和数据采集模块;软件系统是由虚拟场景模块和人机交互模块构成。基于SPSS软件的分析数据结果表明,系统不仅可以准确的采集足底脚掌与脚跟的压力值,而且组内相关系数均大于0.9,系统具有很好的可靠性。本研究的虚拟场景的趣味性很高,能有效地提高患者训练的积极性,并有利于医生制定针对性的康复计划。

Abstract:
The majority of stroke patients have some obstacles in the movement of the lower limbs, which bring great inconvenience to their life. And timely and effective rehabilitation training is the key to recover of lower limb motor function. The traditional rehabilitation training of lower limbs has high repeatability, low participation and poor interaction. To solve the problems, this study designed a lower limb rehabilitation training system based on the virtual scene.The system implemented the combination of virtual reality technology for rehabilitation training and evaluation of lower limbs. It can not only collect and deal with the plantar pressure to control the virtual elements in the virtual scene, but also display the training time, score, the maximum and average value of plantar pressure during training. The system is composed of lower computer hardware and upper computer software. The hardware system consists of force sensor module and data acquisition module. Based on the analysis data of SPSS software, the results show that the system can not only accurately collect the pressure value of plantar sole and heel, but also the intra-class correlation coefficient is greater than 0.9, and the system has good reliability. The software system is composed of virtual scene module and human-computer interaction module.In this study, the virtual scene is very interesting. It can effectively improve the enthusiasm of training for patients, and is conducive to develop the targeted rehabilitation programs.
