Abstract
Method for regulating a prosthesis (1), such as a knee prosthesis, ankle prosthesis or knee/ankle prosthesis, comprising at least one joint (2) controlled by an actuator (3) governed by a microcontroller (4) on the basis of data issuing from at least one gyroscope (5) and an accelerometer (6) that are able to measure the angular speed and the acceleration, respectively, of at least part of the prosthesis (1). According to the invention, the method is such that, during a defined period of time, the microcontroller (4) monitors the measurement given by the gyroscope (5), in such a way that said microcontroller (4) enters an idle state by reducing or by cutting the electrical power of at least one electronic organ of the prosthesis (1), except that of the accelerometer (6), when said microcontroller (4) detects that the absolute value of the measurement given by the gyroscope (5) is below a given threshold during the defined period of time.
