本文介绍了一种8通道经皮神经肌肉刺激器，称为ExoStim，它的设计和开发提供刺激的脊髓损伤个体的下肢肌肉。ExoStim的预期用途是作为植入式神经肌肉刺激器的皮肤表面前体，用于增加瘫痪腿部力量和耐力的特定任务，使患者能够执行基本的下肢功能任务，并熟悉功能性电刺激训练。初始设计规范包括便携性（约500 g）、电池供电输出、恒定电流控制（0-300 mA）、8个双相刺激通道（电荷平衡、恒定电流）和所有刺激参数的微处理器控制。对三个原型装置进行了各种测试，包括输出功率特性、环境、机械和电池寿命，以验证我们的设计规格。ExoStim已成功通过所有测试，现在可以部署到临床试验机构，对脊髓损伤受试者进行进一步评估。
This paper introduces an 8-channel transcutaneous neuromuscular stimulator, called ExoStim, which was designed and developed to provide stimulation to the lower-limb muscles of spinal cord injured individuals. The intended purposes of the ExoStim were to act as a skin-surface precursor to an implantable neuromuscular stimulator for the specific tasks of increasing paralyzed leg strength and endurance, enabling the performance of basic lower-limb functional tasks, and familiarizing patients with functional electrical stimulation training. The initial design specifications included portability (approximately 500 g), battery-powered output, constant current control (0-300 mA), 8 channels of biphasic stimulation (charge-balanced, constant current), and microprocessor control of all stimulation parameters. Various tests, including output power characteristics, environmental, mechanical, and battery life, were performed on three prototype units to validate our design specifications. Having successfully passed all tests, the ExoStim is now ready to be deployed to clinical trial sites for further evaluation with spinal cord injured subjects.
