功能性电刺激(FES)领域的研究小组经常面临这样一个事实，即现有的和商业上可用的FES刺激器不能提供足够的灵活性，并且不能用于执行不同的FES任务。到目前为止，商业系统缺乏灵活性，迫使各种FES研究团队开发自己的刺激器。本文介绍了一种新开发的用于商业Compex 2刺激器的固件和图形编程软件，它增强了刺激器的多功能性和功能，从医疗和治疗设备到神经假体和研究工具。这种名为Compex Motion的新刺激器现在可以用于开发各种定制的神经假体、神经评估设备、肌肉锻炼系统和用于生理学研究的实验装置。它可以被编程为生成任何任意的刺激序列，这些序列可以由各种外部传感器、感官系统或实验室设备控制或调节。通过互连两个或多个Compex运动刺激器，刺激通道的数量可以增加到四个通道的倍数，即8、12、16、20等等。刺激序列和控制策略被编程并存储在可更换的信用卡大小的存储芯片卡上。刺激器具有四个两相电流调节刺激通道和两个通用模拟输入通道，可以配置为测量各种传感器的输出电压，例如测角仪、倾斜仪、陀螺仪或肌电(EMG)传感器。为了实现对刺激模式的实时肌电控制，实现了一种软件刺激伪迹消隐的肌电处理算法。Compex运动刺激器由瑞士公司Compex SA制造，目前正在进行临床试验。
Research groups in the field of functional electrical stimulation (FES) are often confronted with the fact that existing and commercially available FES stimulators do not provide sufficient flexibility and cannot be used to perform different FES tasks. The lack of flexibility of the commercial systems until now forced various FES research teams to develop their own stimulators. This paper presents a newly developed firmware and graphical programming software for the commercial Compex 2 stimulator which enhances the versatility and capabilities of the stimulator from a medical and therapeutic device to a neuroprosthesis and research tool. The new stimulator, called Compex Motion, can now be used to develop various custom-made neuroprostheses, neurological assessment devices, muscle exercise systems, and experimental setups for physiological studies. It can be programmed to generate any arbitrary stimulation sequence that can be controlled or regulated by various external sensors, sensory systems, or laboratory equipment. By interconnecting two or more Compex Motion stimulators, the number of stimulation channels can be increased to multiples of four channels, 8, 12, 16, 20, and so forth. The stimulation sequences and the control strategies are programmed and stored on exchangeable credit card-sized memory chip cards. The stimulator has four biphasic current-regulated stimulation channels and two general purpose analog input channels that can be configured to measure the output voltage of a variety of sensors such as goniometers, inclinometers, gyroscopes, or electromyographic (EMG) sensors. For realtime EMG control of the stimulation patterns, an EMG processing algorithm with software stimulation artifact blanking was implemented. The Compex Motion stimulator is manufactured by the Swiss company Compex SA and is currently undergoing clinical trials.
