This paper presents a low-cost portable system for applying a rehabilitation therapy, based on virtual reality, functional electrical stimulation and a training device. This open-hardware system, intended to support a home-made therapy process in people with reduced dorsiflexion ability, contains three main building blocks: an electromechanical platform, an immersive virtual reality interface and the firmware. The electromechanical training platform is the core of the system, which acts as a gateway interface of sensors-actuators for a closed loop system, through an immersive virtual reality application, the patient closes the loop by acting as the controller by means of a "virtual dummy" preforming in mirror configuration. The platform measures and process the dorsiflexion angle described by both ankles, real-time transmitting the information to the mobile phone virtual application to be presented as a mirror. The onboard microprocessor drives the operation of the electric stimulation interface, which is sent through two channels to both, healthy and affected lower limbs. The platform communicates continuously through a USB bidirectional interface with a personal computer, in which the physician enters the rehabilitation protocol and follows the patient performance. A first case study by using this device has been reported in [1].
本文介绍了一种基于虚拟现实、功能性电刺激和训练设备的低成本便携式康复治疗系统。这个开源硬件系统旨在支持背屈能力下降的人群进行自制治疗过程，它包含三个主要组成部分：一个机电平台、一个沉浸式虚拟现实接口和固件。机电训练平台是系统的核心，它作为传感器 - 执行器的网关接口用于闭环系统，通过沉浸式虚拟现实应用，患者通过以镜像配置执行的“虚拟假人”充当控制器来闭合回路。该平台测量并处理双踝的背屈角度，实时将信息传输到手机虚拟应用中以镜像形式呈现。板载微处理器驱动电刺激接口的运行，该接口通过两个通道发送到健康和受影响的下肢。该平台通过USB双向接口与个人计算机持续通信，医生在个人计算机中输入康复方案并跟踪患者的表现。在[1]中报道了使用该设备的第一个案例研究。
