“…The mechanism is directed by the notion of brain plasticity and human motor learning, and patients will achieve improvement or even recovery of motor function by progressively regaining the capability of motion control through repetitive motion and feedback simulation [4]. With the aid of an exoskeleton, patients can acquire basic abilities like grabbing, walking, climbing stairs and sitting down, which dramatically enhances the quality of their everyday life [5]. This paper will firstly examine two main variations of the powered exoskeleton, including their working principles and operations, before analysing its benefits and drawbacks in comparison to currently available conventional rehabilitation equipment, it will also discuss its emerging problems, and finally, it will discuss its challenges and prospects, along with any improvements that are practical to make.…”
