This study investigated the effects of robot-assisted gait training with body weight support on gait and balance in stroke patients. The study participants comprised 24 patients diagnosed with stroke. Patients were randomly assigned to four groups of six: robot A, B, C, and non-robot. The body weight support (BWS) for the harness of the robot was set to 30% of the patient’s body weight in robot group A, 50% in robot group B, and 70% in robot group C. All experimental groups received robot-assisted gait training and general physical therapy. The non-robot group underwent gait training using a p-bar, a treadmill, and general physical therapy. The intervention was performed for 30 min a day, five times a week, for 6 weeks. All participants received the intervention after the pre-test. A post-test was performed after all of the interventions were completed. Gait was measured using a 10 m Walking test (10MWT) and the timed up and go (TUG) test. Balance was assessed using the Berg Balance Scale (BBS). Robot groups A, B, and C showed significantly better 10MWT results than did the non-robot group (p < 0.5). TUG was significantly shorter in robot groups A, B, and C than in the non-robot group (p < 0.5). The BBS scores for robot group A improved significantly more than did those for robot groups B and C and the non-robot group (p < 0.5), indicating that robot-assisted gait training with body weight support effectively improved the gait of stroke patients.
本研究旨在探讨机器人辅助减重步态训练对脑卒中患者步态和平衡能力的影响。研究对象为 24 名被诊断为脑卒中的患者。患者被随机分为四组，每组 6 人：机器人 A 组、机器人 B 组、机器人 C 组和非机器人组。机器人 A 组、机器人 B 组和机器人 C 组患者的减重吊带所承受的体重分别为患者体重的 30%、50%和 70%。所有实验组均接受机器人辅助步态训练和常规物理治疗。非机器人组则使用 p 杆、跑步机和常规物理治疗进行步态训练。干预时间为每天 30 分钟，每周 5 次，共 6 周。所有患者在完成预测试后均接受干预。所有干预结束后进行后测试。使用 10 米步行测试（10MWT）和计时起立行走测试（TUG）来测量步态。平衡能力则通过 Berg 平衡量表（BBS）来评估。机器人 A 组、机器人 B 组和机器人 C 组的 10MWT 结果明显优于非机器人组（p<0.5）。机器人 A 组、机器人 B 组和机器人 C 组的 TUG 时间明显短于非机器人组（p<0.5）。机器人 A 组的 BBS 评分明显高于机器人 B 组、机器人 C 组和非机器人组（p<0.5），这表明减重支撑的机器人辅助步态训练能有效改善脑卒中患者的步态。
