Patients with chronic stroke often have difficulty opening their hands and performing grasping movements. Several passive hand orthoses for assisting hand rehabilitation have been developed and demonstrated to be clinically effective. However, current devices have several limitations, such as supporting only a single grasping motion and using an abnormal grasping posture. Therefore, this study developed a three-dimensional (3D)-printed multifunctional hand device (3DP-MFHD) to solve these problems and evaluated the feasibility of using the device during home rehabilitation. Six participants were enrolled, and each of them was provided with the 3DP-MFHD. In addition to a task-oriented training course, the participants were asked to train at home for 4 weeks for at least 5 days per week and 40 min per day. The results revealed that hand grip force increased by 36.1%, lateral pinch force increased by 17.6%, and the Action Research Arm Test score increased by 54.1%. The 3DP-MFHD is a promising means to facilitate hand rehabilitation and improve hand strength and function in patients with chronic stroke. The 3DP-MFHD can be used as part of home rehabilitation.
慢性中风患者常难以张开手掌和进行抓握动作。已经开发出几种用于辅助手部康复的被动手部矫形器，并已证明其在临床上有效。然而，目前的设备存在一些局限性，例如仅支持单一的抓握动作和使用异常的抓握姿势。因此，本研究开发了一种三维（3D）打印多功能手部设备（3DP-MFHD）来解决这些问题，并评估了在家庭康复中使用该设备的可行性。招募了 6 名参与者，并为他们每个人提供了 3DP-MFHD。除了进行以任务为导向的培训课程外，参与者还被要求在家中进行为期 4 周的训练，每周至少 5 天，每天 40 分钟。结果表明，手抓握力增加了 36.1%，侧捏力增加了 17.6%，动作研究手臂测试评分增加了 54.1%。3DP-MFHD 是一种有前途的促进手部康复的手段，可以提高慢性中风患者的手部力量和功能。3DP-MFHD 可作为家庭康复的一部分。
