Foot Drop (FD) is a condition, which is very commonly found in post-stoke patients; however it can also be seen in patients with multiple sclerosis, and cerebral palsy. It is a sign of neuromuscular damage caused by the weakness of the muscles. There are various approaches of FD's rehabilitation, such as physiotherapy, surgery, and the use of technological devices. Recently, researchers have worked on developing various technologies to enhance assisting and rehabilitation of FD.
This review analyzes different types of technologies available for FD. This include devices that are available commercially or still under research101 studies published between 2015 and 2020 were identified for the review, many were excluded due to various reasons, e.g., were not robot-based devices, did not include FD as one of the targeted diseases, or was insufficient information. 24 studies that met our inclusion criteria were assessed. These studies were further classified into two different categories: robot-based ankle-foot orthosis (RAFO) and Functional Electrical Stimulation (FES) devices.
Studies included showed that both RAFO and FES showed considerable improvement in the gait cycle of the patients. Future trends are inclining towards integrating FES with other neuro-concepts such as muscle-synergies for further developments.
足下垂(FD)是一种在中风后患者中非常常见的病症;但也可见于多发性硬化症和脑瘫患者。它是由肌肉无力引起的神经肌肉损伤的标志。FD 的康复有各种方法,如物理疗法、手术和使用技术设备。最近,研究人员致力于开发各种技术来增强 FD 的辅助和康复。
本综述分析了 FD 可用的各种技术。其中包括市售或仍在研究中的设备。为了进行综述,确定了 2015 年至 2020 年期间发表的 101 项研究,但由于各种原因,许多研究被排除在外,例如不是基于机器人的设备、不将 FD 作为目标疾病之一、或信息不足。评估了符合我们纳入标准的 24 项研究。这些研究进一步分为两类:基于机器人的踝足矫形器(RAFO)和功能性电刺激(FES)设备。
纳入的研究表明,RAFO 和 FES 都在患者的步态周期中显示出相当大的改善。未来的趋势倾向于将 FES 与其他神经概念(如肌肉协同作用)集成,以进行进一步的开发。
