  • Publication number: 20190142621
    Abstract: A foot assistive device for improving drop foot gait comprises an assistive device body and an elastic module. The assistive device body comprises a foot support base and a brace. The foot support base is movably connected to the brace. The elastic module connects the foot support base to the brace. The elastic module has a spring, a preset support included angle is formed between the foot support base and the brace under an elastic force of the spring. The support included angle is not larger than 90°. Thereby, when the foot is raised up, the foot support base is unlikely to drop excessively due to the foot weight, the drop foot gait is improved effectively.
