During the postoperative hand rehabilitation period, it is recommended that the repaired flexor tendons be continuously glided with sufficient tendon excursion and carefully managed protection to prevent adhesion with adjacent tissues. Thus, finger joints should be passively mobilized through a wide range of motion (ROM) with physiotherapy. During passive mobilization, sequential flexion of the metacarpophalangeal (MCP) joint followed by the proximal interphalangeal (PIP) joint is recommended for maximizing tendon excursion. This paper presents a lightweight device for postoperative flexor tendon rehabilitation that uses a single motor to achieve sequential joint flexion movement. The device consists of an orthosis, a cable, and a single motor. The degree of spatial stiffness and cable path of the orthosis were designed to apply a flexion moment to the MCP joint prior to the PIP joint. The device was tested on both healthy individuals and a patient who had undergone flexor tendon repair surgery, and both flexion and extension movement could be achieved with a wide ROM and sequential joint flexion movement using a single motor.
在术后手部康复期间，建议连续滑动修复的屈肌腱，以确保有足够的肌腱活动度，并小心保护，以防止与邻近组织粘连。因此，应通过理疗进行手指关节的大范围被动活动（ROM）。在被动活动期间，建议先弯曲掌指关节（MCP），然后再弯曲近侧指间关节（PIP），以最大限度地增加肌腱活动度。本文提出了一种用于术后屈肌腱康复的轻型装置，该装置使用单个电机实现顺序关节弯曲运动。该装置由矫形器、电缆和单个电机组成。矫形器的空间刚度和电缆路径的设计目的是在 PIP 关节之前对 MCP 关节施加弯曲力矩。该装置在健康人和接受过屈肌腱修复手术的患者身上进行了测试，结果表明，该装置可以实现大范围的屈伸运动，并使用单个电机实现顺序关节弯曲运动。
