This invention discloses a functional electrical stimulation rehabilitation aid for stroke, belonging to the field of medical rehabilitation aid technology. It includes an electrical stimulation component, a walking component, a height adjustment component, a body support adjustment component, and a rehabilitation component. This device integrates the electrical stimulation component, the body support adjustment component, and the lower limb rehabilitation training component into one unit, overcoming the limitations of traditional devices that separate head electrical stimulation from limb training. It transmits precise electrical signals to the head's nerve function areas through flexible electrode pads within the helmet, directly promoting the repair and regeneration of damaged nerves. Furthermore, the servo motor-driven linkage mechanism in the rehabilitation component simulates human gait, achieving passive training of lower limb joints and muscles. This eliminates the need for patients to transfer between multiple devices, reducing physical exertion and avoiding safety risks during transfers, making it particularly suitable for acute-phase patients with weak limb mobility.
