摘要

For the elderly, aging and organ function degradation is a common phenomenon, which is manifested in the elderly's limb stiffness, decreased flexibility, mobility, and nervous system function degradation. When the nervous system problems, will lead to human walking disorders, which makes their daily life affected. Stroke is a high incidence in China, mostly in the elderly. At the same time, with the rapid development of modern transportation system and the popularity of transportation, traffic accidents are increasing year by year at an amazing speed. The typical injuries of the injured include nerve injury and limb injury. In order to recover and improve the limb motor function of the injured, scientific rehabilitation training is indispensable. Because of the damage of motor function, these patients generally have some movement disorders, they can not carry out rehabilitation training alone, and need the assistance of medical staff or other professionals. However, due to the lack of professional nursing staff and high medical costs, most Chinese patients prefer to train at home, which brings a serious problem. Due to the wrong training method and the lack of training, patients will miss the best time for rehabilitation. Many cases have shown that due to improper or insufficient intensity of rehabilitation training, patients' physical activity ability is gradually lost. However, according to the survey, most of the lower limb rehabilitation training devices on the market are used by hospitals and self-employed people. Although this meets the needs of patients, the equipment is huge and expensive, and some bedridden patients can't afford it at home, which affects the entry of lower limb rehabilitation training device into the family. The research and development of rehabilitation robot in China started late, with low level and few achievements. Therefore, our intelligent lower limb rehabilitation training system is dedicated to this vacant part of the market. It is not only for the needs of individual users for ＂convenience＂, but also has complete functions, low price, small size, wearable, and can be matched with VR training system. After wearing VR glasses, patients can enter different scenes, such as walking in the garden, jogging, and swimming In different scenarios, our lower limb rehabilitation training device intelligently moves the lower limbs of patients to do related movements. The industry prospect is optimistic, and there is a large space for development. This paper presents the design of a lower limb rehabilitation robot. In this paper, the overall framework of a wearable lower limb rehabilitation training robot is built, and its working principle and basic composition are briefly introduced.
