Method of controlling a prosthesis controlled by a microcontroller, and prosthesis equipped with a microcontroller for the implementation of the control method.

A method of controlling a prosthesis such as a prosthetic knee, ankle or knee-ankle comprising at least one controlled hinge by an actuator controlled by a microcontroller from data from at least one gyroscope and accelerometer capable of respectively measuring the angular velocity and acceleration of at least a portion of the prosthesis. According to the invention, the process consists in that, during a determined time period, the microcontroller monitors the measurement given by the gyroscope so that said microcontroller enters a standby state by reducing or cutting off the power supply to at least one electronic component of the prosthesis, with the exception of that of the accelerometer when said microcontroller detects that the absolute value of the gyroscope by the given measurement is less than a given threshold during the period of time.
