For patients with spinal cord injury (SCI), traditional methods include physical therapy and occupational therapy, etc. These therapies can relieve muscle atrophy and other related symptoms. Traditional therapies can have only a limited effect. With the combination of rehabilitation medicine and robotics technology, the research of rehabilitation robot has made some progress. Rehabilitation robot with its automation, accurate and intelligent features begins to replace human beings to complete some simple tasks, and becomes a new hot spot in robotics. Rehabilitation robot brings opportunities to the traditional rehabilitation theory and also brings new challenges. This article has analyzed the status of domestic and international rehabilitation robots, the latest development and critical technologies. According to the latest rehabilitation robot researches, this article has designed a rehabilitation robot with surface electromyography (sEMG) and functional electrical stimulation (FES) for patients with SCI. Then, this article has described the mechanical structure, the control system, the related sensors and hardware architecture design. This article has comprehensively utilized various technologies of rehabilitation robot to conduct a study on rehabilitation training. After that, the kinematics and dynamics of the rehabilitation robot has been analyzed and then the control methods of passive training based on adaptive neural network control have also been researched. On the other hand, the effect of the functional electrical stimulation (FES) to the paraplegic patients has been widely studied in the international arena and has made some progress. However, many studies use only a small number of muscles stimulated by FES to achieve specific rehabilitation movement, or just use FES to stimulate muscles in patients with single-joint movement. There are relatively few studies on fully using of FES to achieve active training. Full use of FES to achieve a specific action is not only important for rehabilitation, but also very important to increase the activities of daily living (ADL). Currently, when applied electrical stimulation, the majority of the researches are based on the muscle activation timing in a specific movement to impose stimulation pulse with fixed pattern. This approach need a lot of time to try the stimulation pulse pattern. Meanwhile, it can not adapt to the muscle fatigue, muscular and some other physiological parameters, or external in...
