背景：混合辅助肢（HAL）（可穿戴机器人）可以通过检测佩戴者皮肤表面的生物电信号来辅助运动，从而自主控制髋关节和膝关节运动。本研究的目的是报道可穿戴机器人治疗慢性脊髓病患者后纵韧带骨化（OPLL）手术后的行走能力。结果：患者是一名66岁的女性，患有颈椎OPLL，在双侧拐杖的帮助下能够独立行走。手术后大约14年开始，每2周接受一次可穿戴机器人治疗，共10次。基于10米步行测试和评估总步行距离的2分钟步行测试（BL 63.4； 103.7米），观察到步态速度（BL 22.5；后46.7米/分钟）、步长（BL 0.36；后0.57米）和节奏（BL 61.9；后81.6米/分钟）的改善。可穿戴机器人治疗6个月后，行走能力的改善得以维持。结论：我们报道了一名慢性脊髓型颈椎病患者在可穿戴机器人治疗后行走能力的功能恢复，这表明可穿戴机器人作为一种康复工具，有可能有效改善慢性脊髓型颈椎病患者的行走能力，这些患者的行走能力已经达到平台期，甚至在手术后多年。
Context: The hybrid assistive limb (HAL) (the wearable robot) can assist kinesis during voluntary control of hip and knee joint motion by detecting the wearer's bioelectric signals on the surface of their skin. The purpose of this study was to report on walking ability following the wearable robot treatment in a patient with chronic myelopathy after surgery for cervical ossification of the posterior longitudinal ligament (OPLL).Findings: The patient was a 66-year-old woman with cervical OPLL who was able to ambulate independently with the aid of bilateral crutches. The wearable robot treatment was received once every 2 weeks for ten sessions beginning approximately 14 years after surgery. Improvements were observed in gait speed (BL 22.5; post 46.7 m/min), step length (BL 0.36; post 0.57 m), and cadence (BL 61.9; post 81.6 m/min) based on a 10-m walk test and a 2-minute walk test (BL 63.4; post 103.7 m) assessing total walking distance. The improvements in walking ability were maintained after the wearable robot treatment for 6 months.Conclusion: We report the functional recovery in the walking ability of a patient with chronic cervical myelopathy following the wearable robot treatment, suggesting that as a rehabilitation tool, the wearable robot has the potential to effectively improve functional ambulation in chronic cervical myelopathy patients whose walking ability has plateaued, even many years after surgery.
