Shoulder subluxation is a frequent complication of motor impairment after stroke, leading to soft tissue damage, stretching of the joint capsule, rotator cuff injury, and in some cases pain, thus limiting use of the affected extremity beyond weakness. In this pilot study, we determined whether robotic treatment of chronic shoulder subluxation can lead to functional improvement and whether any improvement was robust.
18 patients with chronic stroke (3.9 ± 2.9 years from acute stroke), completed 6 weeks of robotic training using the linear shoulder robot. Training was performed 3 times per week on alternate days. Each session consisted of 3 sets of 320 repetitions of the affected arm, and the robotic protocol alternated between training vertical arm movements, shoulder flexion and extension, in an anti-gravity plane, and training horizontal arm movements, scapular protraction and retraction, in a gravity eliminated plane.
Training with the linear robot improved shoulder stability, motor power, and resulted in improved functional outcomes that were robust 3 months after training.
In this uncontrolled pilot study, the robotic protocol effectively treated shoulder subluxation in chronic stroke patients. Treatment of subluxation can lead to improved functional use of the affected arm, likely by increasing motor power in the trained muscles.
肩部半脱位是中风后运动功能障碍的常见并发症，可导致软组织损伤、关节囊拉伸、肩袖损伤，在某些情况下还会引起疼痛，从而限制了患侧肢体的使用，使其不仅因无力而受限。在这项初步研究中，我们确定了机器人治疗慢性肩部半脱位是否可以改善功能，以及任何改善是否具有稳健性。
18 名慢性中风患者（从急性中风开始 3.9±2.9 年），使用线性肩部机器人完成了 6 周的机器人训练。每周训练 3 次，隔天进行。每个疗程包括 3 组 320 次患侧手臂的重复运动，机器人方案在抗重力平面中交替训练垂直手臂运动、肩前屈和伸展，以及在消除重力的平面中训练水平手臂运动、肩胛骨前伸和缩回。
使用线性机器人进行训练可改善肩部稳定性和运动能力，并在训练 3 个月后产生稳健的功能改善效果。
在这项非对照初步研究中，机器人方案有效地治疗了慢性中风患者的肩部半脱位。治疗半脱位可以改善患侧手臂的功能使用，可能是通过增加训练肌肉的运动能力。
