摘要

神经肌肉疾病影响着全世界数百万人。上肢震颤是一种常见的症状,由于其复杂的病因,很难补偿,除非在特殊情况下通过手术干预或药物治疗。机械补偿肢体震颤的可穿戴设备可以使相当多的患者受益,但以这种方式帮助患者的技术还不发达。在本文中,我们提出了一种创新的矫形器,可以动态地抑制病理性震颤,通过在受影响的肢体上以可控的方式施加粘性阻尼。矫形器的设计采用了一种基于磁流变流体的新型致动器设计,可以有效地响应瞬时震颤频率和幅度,提供阻尼作用。

Upper limb tremor suppression in ADL via an orthosis incorporating a controllable double viscous beam actuator
Neuromuscular disorders affect millions of people worldwide. Upper limb tremor is a common symptom, and due to its complex aetiology it is difficult to compensate for except, in particular cases by surgical intervention or drug therapy. Wearable devices that mechanically compensate for limb tremor could benefit a considerable number of patients, but the technology to assist suffers in this way is under-developed. In this paper we propose an innovative orthosis that can dynamically suppress pathological tremor, by applying viscous damping to the affected limb in a controlled manner. The orthosis design utilises a new actuator design based on magneto-rheological fluids that efficiently deliver damping action in response to the instantaneous tremor frequency and amplitude.
