With the improvement of living standards, the reduction of physical labor, the risk of people suffering from stroke leading to paraplegia greatly increased. However the corresponding medical resources support has not kept up and the rehabilitation doctor is not enough either. So the demand for rehabilitation equipment grows and the rehabilitation technology needs to be improved rapidly. In fact the current market lack of medical equipment for gait rehabilitation, at the same time, the existing gait rehabilitation of medical devices are all with single function, poor product quality, poor adaptability, poor patient participation, so it is difficult to meet the patient's need for rehabilitation and the hospital's need for equipment in the current situation. Based on this, we have designed ProWalk, a lightweight, universal, functional, highly involved, simple and effective wearable exoskeleton robot, to fill the gaps in the industry and improve the effect of rehabilitation, reduce the burden of rehabilitation. ProWalk is based on bionic design, according to human characteristics, designed to cover height of 150 to 190cm and weight under 100Kg with both comfort and adaptability; It weights 4Kg which greatly reduce the burden on patients. ProWalk has three functions of sitting station training, balance training, gait training. With these function ProWalk can cover the patient from sitting on the bed to leaving the hospital. ProWalk can identify the patient's intention, maximize patient participation, speed up recovery with the use of machine learning-based intention recognition and human-computer interaction algorithm. Reducing the burden on the rehabilitation therapist greatly.
