Abstract

Forearm disabilities can result from a number of diseases or injuries, such as stroke, spinal cord injuries (SPI), and acquired/traumatic brain injuries (ABI/TBI). Patients with forearm disabilities suffer from daily activities and follow-up care and rehabilitation are critical to recovery of the patients in this case. However, they have to make personal trips to clinics or hospitals for follow-up treatments since most of existing devices available are bulky, heavy and even expensive in general, discouraging the patients from having them home. This paper proposes a pneumatic inflatable rehabilitation device designed with bio-inspiration. The device is lightweight, safe, and affordable compared to conventional devices. When the actuators of the device are inflated, the contractions of the actuators mimic the motions of the human muscles of the forearm, assisting pronation and supination. The actuators are made of heat-sealable fabrics using a custom-built patterning system. This system facilitates rapid fabrication of repetitive and complex sealing patterns. Also, the proposed rehabilitation device, which can be conjointly used with typical clothing materials, provides comfort for the user by easily conforming the three-dimensional geometries of the forearm. To characterize the system, the angles and the torques of the wrist generated by the device were measured. The result of simple closed-loop control using a vision feedback was also presented.
一种用于前臂旋前和旋前康复的轻质柔软可穿戴套筒
前臂残疾可由多种疾病或损伤引起,如中风、脊髓损伤(SPI)和获得性/外伤性脑损伤(ABI/TBI)。前臂残疾患者日常活动不便,后续护理和康复对患者的康复至关重要。然而,他们必须亲自前往诊所或医院进行后续治疗,因为现有的大多数设备体积大,重量重,甚至普遍昂贵,使患者不愿将其带回家。提出了一种采用生物灵感设计的气动充气康复装置。与传统设备相比,该设备重量轻、安全、价格实惠。当装置的致动器充气时,致动器的收缩模仿人类前臂肌肉的运动,辅助旋前和旋后。执行器由热密封织物制成,使用定制的图案系统。该系统有助于快速制造重复和复杂的密封图案。此外,所提出的康复装置可以与典型的服装材料联合使用,通过容易地符合前臂的三维几何形状,为用户提供舒适。为了表征该系统,测量了该装置产生的手腕角度和扭矩。给出了基于视觉反馈的简单闭环控制结果。
