The utility model relates to a nursing ankle appliance for preventing foot drop, which belongs to the technical field of nursing appliances and comprises a bottom plate, the top of the bottom plate is provided with a limiting mechanism and a damping mechanism, the top of the limiting mechanism is provided with a mounting mechanism, and the mounting mechanism comprises a limiting plate. And the limiting mechanism comprises a mounting cylinder, a locking nut and a threaded rod. The leg angle adjusting device has the advantages that by arranging the limiting mechanism, when the angle of the device needs to be adjusted in use, the limiting plate can be rotated by adjusting the length of the threaded rod, then the angle of the device is adjusted, people can adjust the angle and position of the legs conveniently, and the leg angle adjusting device is fixed through the locking nut and is convenient to use. The device is simple in structure and convenient to use, fixing adjustment of the device is facilitated, leg training and movement are facilitated, convenience is achieved, meanwhile, the damping mechanism is adopted, impact and vibration are effectively absorbed, the influence of disturbance of environments and objects on the device is reduced, and therefore the device can be stably and stably used.

The present invention proposes an intelligent drop foot electrical stimulation system and method with muscle fatigue detection. The method comprises: sensing motion posture data of a lower leg by means of a first inertial sensor; sensing motion posture data of a foot by means of a second inertial sensor; determining a gait stage on the basis of the motion posture data, and calculating a lower leg angle and a foot angle; when the gait stage belongs to a swing phase, controlling an electrical stimulator to generate a first pulse wave to at least one electrode to stimulate the lower leg; and determining, on the basis of the foot angle, whether muscle fatigue occurs in the lower leg during the swing phase, and if the muscle fatigue occurs, controlling the electrical stimulator to generate a second pulse wave to the electrode to stimulate the lower leg, wherein wave parameters of the first pulse wave are different from wave parameters of the second pulse wave. Thus, the problem of insufficient stimulation caused by muscle fatigue can be solved.

An ankle and foot orthotic device biases the foot of a user into dorsiflexion to control drop foot and other conditions caused by neurological or muscular impairment; allowing a user to stand, walk, and participate in desired activities with greater ease and balance. The device resists rapid motions of the foot and assists the user in many aspects of walking including controlling the drop of the foot front after heel strike, stabilizing standing in a neutral position, and strengthening the ability to push off of the toes at the end of the stride.
