The invention discloses a wearable intelligent foot drop corrector and a correction method. The invention realizes correction by adopting a processing unit to receive and process the sensing signals returned by a tilt sensor and pressure sensors, convert the shank tilt angle signal returned by the tilt sensor into a value corresponding to the shank tilt angle, compare the processed shank tilt angle value and the preset tilt angle switching threshold, simultaneously monitor whether the pressure signals returned by the pressure sensors arranged at the heels of the user bear the weight pressure of the user in real time and send an electric pulse stimulation signal to a simulation circuit to trigger a simulating electrode to generate simulated current when the measured value of the tilt sensor reaches or is more than the opening threshold and the pressure sensors arranged at the heels of the user bear the weight pressure of the user. The corrector has the characteristics of simple structure, convenient use, obvious effect and low cost and is suitable for being popularized in the field of foot drop treatment.
