Case series. Robot-assisted rehabilitation mediated by exoskeletal devices is a popular topic of research. The biggest difficulty in the development of rehabilitation robots is the consideration of the clinical needs. This study investigated the usability of a novel cable-driven exoskeletal robot specifically designed for hand rehabilitation. The study consists of three steps, including prototype development, spasticity observation, and usability evaluation. First, we developed the prototype robot to manipulate the patient's fingers based on the clinical needs and the cable-driven concept established in our previous work. Second, we applied to patients with different levels of spasticity. Finally, we obtained the system usability scale (SUS) and assessed its usability. Two healthy subjects were recruited in the pre-test, and 18 patients with stroke and four healthy subjects were recruited in the formal test for usability. The total SUS score obtained from the patients and healthy subjects was 94.77 ± 2.98 ( = 22), indicating an excellent level of usability. The satisfaction score was 4.74 ± 0.29 ( = 22), revealing high satisfaction with . The tension profile measured by the cables showed the instantaneous force used to manipulate fingers among different muscle tone groups. meets the clinical needs with excellent usability, satisfaction, and reliable tension force monitoring, yielding a feasible platform for robot-assisted hand rehabilitation.
病例系列。由外骨骼设备介导的机器人辅助康复是一个热门的研究课题。康复机器人开发中最大的困难在于临床需求的考量。本研究调查了一种专门为手部康复设计的新型缆索驱动外骨骼机器人的可用性。该研究包括三个步骤，即原型开发、痉挛观察和可用性评估。首先，我们基于临床需求和我们之前工作中确立的缆索驱动概念开发了用于操控患者手指的原型机器人。其次，我们将其应用于不同痉挛程度的患者。最后，我们获得了系统可用性量表（SUS）并评估其可用性。预测试招募了2名健康受试者，正式测试招募了18名中风患者和4名健康受试者以评估可用性。患者和健康受试者获得的SUS总分为94.77±2.98（n = 22），表明可用性极佳。满意度评分为4.74±0.29（n = 22），显示出对……的高度满意。缆索测量的张力曲线显示了用于操控不同肌张力组手指的瞬时力。……以出色的可用性、满意度和可靠的张力监测满足了临床需求，为机器人辅助手部康复提供了一个可行的平台。
