中风幸存者可能会受到手部运动缺陷的影响。与脑机接口（BMI）相关的机器人设备可能有助于这些患者的运动康复。通过运动想象练习进行矫正控制的BMI已经成功地恢复了中风患者的运动。然而，患者和临床医生对可用的机器人设备的接受程度仍然很低，主要是因为所涉及的成本很高。基于此背景，本研究旨在设计和构建用于康复目标的手外骨骼（HERO），以恢复手指的伸展和屈曲运动。使用与纺织品相关联的三维（3D）打印技术来生产轻质和可穿戴设备。3D打印执行器也被设计用于降低设备成本。驱动器将直流电机的扭矩转换为线性力，通过鲍登电缆传输，以被动地移动手指。外骨骼由神经电信号-脑电图（EEG）控制。进行了概念试验以评价控制性能。根据Graz-BCI协议，一名健康的志愿者接受了外骨骼训练。用二维（2D）跟踪软件和相关性分析评价工效学。英雄可以与普通服装相比。手的重量约为102 g。参与者能够控制外骨骼，分类准确率为91.5%。HERO项目产生了一种重量轻、简单、便携、符合人体工程学和低成本的设备。它的使用不限于临床环境。因此，用户将能够在医院、康复诊所和家中使用HERO进行运动训练，从而增加康复干预时间。这可以支持运动康复并改善中风幸存者的生活质量。
Stroke survivors can be affected by motor deficits in the hand. Robotic equipment associated with brain–machine interfaces (BMI) may aid the motor rehabilitation of these patients. BMIs involving orthotic control by motor imagery practices have been successful in restoring stroke patients' movements. However, there is still little acceptance of the robotic devices available, either by patients and clinicians, mainly because of the high costs involved. Motivated by this context, this work aims to design and construct the Hand Exoskeleton for Rehabilitation Objectives (HERO) to recover extension and flexion movements of the fingers. A three-dimensional (3D) printing technique in association with textiles was used to produce a lightweight and wearable device. 3D-printed actuators have also been designed to reduce equipment costs. The actuator transforms the torque of DC motors into linear force transmitted by Bowden cables to move the fingers passively. The exoskeleton was controlled by neuroelectric signal—electroencephalography (EEG). Concept tests were performed to evaluate control performance. A healthy volunteer was submitted to a training session with the exoskeleton, according to the Graz-BCI protocol. Ergonomy was evaluated with a two-dimensional (2D) tracking software and correlation analysis. HERO can be compared to ordinary clothing. The weight over the hand was around 102 g. The participant was able to control the exoskeleton with a classification accuracy of 91.5%. HERO project resulted in a lightweight, simple, portable, ergonomic, and low-cost device. Its use is not restricted to a clinical setting. Thus, users will be able to execute motor training with the HERO at hospitals, rehabilitation clinics, and at home, increasing the rehabilitation intervention time. This may support motor rehabilitation and improve stroke survivors life quality.
