The objective of this research study was to investigate the effect of patient-centered robot-assisted intervention for upper limb function improvement in stroke patients. Design: A double-blind randomized controlled trial. Intervention: Subjectively preferred areas of need for performing daily activities were identified by pre-interviewing and applied as target goals in the experimental group using a robotic device. Control-1 underwent a program focused on the robot system involving movements of upper limb joints. Control-2 participated in a conventional rehabilitation program. Methods: Forty-five participants engaged in 60 min of daily therapy, five times weekly for 3 weeks. The experimental group used the Canadian occupational performance measure (COPM) to identify subjectively preferred “patient-centered” focus needed areas to perform robotic device aided daily activities. Control-1 used a robot device-focused rehabilitation involving upper limb joint movements. Control-2 participated in conventional rehabilitation. Pre-post intervention measurements of hand, grip, power, and upper limb ROM were acquired by FMA-UE, MFT, and K-MBI. Results: A significant increase of function in the experimental group was observed in each subclass of function and activities of daily living (ADL) performance. Control-1 showed an increase in function without ADL improvement. Control-2 showed an increase in ADL and proximal areas of upper limb function without an increase in other areas. Conclusion: The “patient-centered” approach significantly improved upper limb function and ADL performance compared to “robot-centered” rehabilitation. Further studies are warranted to confirm these results and for generalizability in clinical application.

一项关于使用以患者为中心的机器人辅助康复对亚急性中风患者功能改善的职业治疗干预效果的随机对照试验

本研究旨在探讨以患者为中心的机器人辅助干预对脑卒中患者上肢功能改善的效果。 设计：一项双盲随机对照试验。 干涉：通过预采访确定了需要进行日常活动的主观偏好领域，并使用机器人设备将其作为实验组的目标目标。Control-1 接受了一个专注于机器人系统的程序，该系统涉及上肢关节的运动。Control-2 参加了一项传统的康复计划。 方法：45 名参与者每天进行 60 分钟的治疗，每周 5 次，持续 3 周。实验组使用加拿大职业绩效测量 (COPM) 来确定主观偏好的“以患者为中心”的重点需要区域，以执行机器人设备辅助的日常活动。Control-1 使用了以机器人设备为中心的康复训练，涉及上肢关节运动。Control-2 参与了常规康复治疗。通过 FMA-UE、MFT 和 K-MBI 获得手、握力、力量和上肢 ROM 的干预前测量。 结果：在功能和日常生活活动（ADL）表现的每个亚类中观察到实验组的功能显着增加。Control-1 在没有 ADL 改善的情况下显示功能增加。Control-2 显示上肢功能的 ADL 和近端区域增加，而其他区域没有增加。 结论：与“以机器人为中心”的康复相比，“以患者为中心”的方法显着改善了上肢功能和 ADL 性能。需要进一步的研究来证实这些结果和临床应用的普遍性。
