由于神经肌肉疾病（例如，杜氏肌营养不良症）的人经常失去肌肉力量，成为轮椅上。尽可能多地使用肌肉是很重要的。为了允许这一点，并增加患者的独立性，手臂矫形器可以用于执行日常生活活动。矫形器补偿手臂的重力，使人们能够用较小的肌肉力量进行运动。对于患者来说，矫形器的美观是关键问题之一。本文介绍了被动式和可穿戴式主动臂矫形器的最新技术，并研究了如何为可穿戴式被动臂矫形器提供合适的结构，该结构能够在其自然运动范围内平衡手臂，并且不显眼;在理想情况下，它适合在衣服下面。对现有器械的身体界面、体积和工作空间进行了研究。根据这些评估指标，调查设备在多大程度上是可穿戴的和不显眼的。此外，该装置的平衡原理，架构，通过装置的力传递，并与身体关节对齐进行了研究。文献中似乎只有一种可穿戴式被动矫形器。这种矫形器可以在手臂的整个自然工作空间中发挥作用，但仍然太笨重而不显眼。其他被动矫形器很显眼，安装在轮椅上。除了一个，可穿戴的主动矫形器都很显眼，而且很重，因为有一个大背包来装驱动器。他们也无法实现人类手臂的整个自然工作空间。未来设计的不显眼、可穿戴的被动手臂矫形器应该贴近身体，佩戴舒适，并支持旋前和旋后。
Due to neuromuscular disorders (e.g., Duchenne Muscular Dystrophy) people often loose muscle strength and become wheelchair bound. It is important to use muscles as much as possible. To allow this, and to increase independency of patients, an arm orthosis can be used to perform activities of daily life. The orthosis compensates for the gravity force of the arm, allowing people to perform movements with smaller muscle forces. For patients, the aesthetics of the orthosis is one of the critical issues. This paper presents the state-of-the-art in passive and wearable active arm orthoses, and investigates how to proceed towards a suitable structure for a wearable passive arm orthosis, that is able to balance the arm within its natural range of motion and is inconspicuous; in the ideal case it fits underneath the clothes. Existing devices were investigated with respect to the body interface, the volume, and the workspace. According to these evaluation metrics it is investigated to what extent the devices are wearable and inconspicuous. Furthermore, the balancing principle of the devices, the architecture, force transmission through the devices, and alignment with the body joints are investigated. It appears that there is only one wearable passive orthosis presented in literature. This orthosis can perform throughout the natural workspace of the arm, but is still too bulky to be inconspicuous. The other passive orthoses were conspicuous and mounted to the wheelchair. Except one, the wearable active orthoses were all conspicuous and heavy due to a large backpack to enclose the actuators. They also could not achieve the entire natural workspace of the human arm. A future design of an inconspicuous, wearable, passive arm orthoses should stay close to the body, be comfortable to wear, and supports pronation and supination.
