目的：根据手外伤后手功能障碍的特点，基于虚拟现实技术研制出一种增强手部肌力和协调性的手功能康复训练系统。
方法：通过贴片式压力传感器实时采集患手的力学信息，将其输入到虚拟现实环境中驱动虚拟环境的运行，该系统能够智能设置虚拟环境中执行任务的难度，根据采集到的力学信息作出相应的康复评价。本文从总体构思，系统的组成和功能设计，系统实现所采用的力传感器模块、采集模块、虚拟现实模块和评估模块开发等方面进行介绍，并进行了初步的临床对照试验。
结果：研制出基于虚拟现实技术的手功能康复系统；通过2周的临床试验，试验组在侧捏力（0.64±0.75N vs 0.09±0.21N）、握力（2.14±1.57N vs 0.81±1.00N）、ADL评分（3.44±2.45 vs 0.67±2.82）方面改善均优于对照组(P<0.05)。
结论：该系统具有成本低、结构简单、易于维护、安全性高等特点，有助于推动虚拟现实技术在手功能康复治疗领域中的应用。 |

| Abstract
Objective：To design a hand function rehabilitation system based on virtual reality technology to enhance hand strength and coordination in patients with hand dysfunction after hand injuries.
Method: The force information of affected fingers was online sampled by strain gauges and fed into the virtual reality (VR) game environment as a control input. The system could set the level of virtual game intelligently, and make rehabilitation evaluation according to the sampled strength information. The design and building of a virtual reality technology-based rehabilitation system for patients with hand injury was presented, including overall idea, functional design and structure of the system. And the key technology to achieve system implementation, such as the force sensor module, collection module, virtual reality module and evaluation module, were discussed in detail. A clinical controlled trial was conducted in patients with hand injuries.
Result: A system for hand rehabilitation was developed based on virtual reality. The difference of lateral pinch strength (0.64±0.75N vs 0.09±0.21N),grasp strength(2.14±1.57N vs 0.81±1.00N) and ADL(3.44±2.45 vs 0.67±2.82)between the trial group and control group had statistical significance(P<0.05).
Conclusion: The advantages of this system include low cost, ease of manufactory, maintenance and good security. So，it will have a good prospects in hand function rehabilitation field. |
