A prosthesis or an orthosis comprising: a plurality of mobile components, each component being able to be moved by a respective motor (7)； and a control device that controls the movement of the moving components and stores predetermined current values for the respective motors (7), characterized in that the prosthesis or orthosis also includes a current measurement circuit that measures the current obtained by the respective motors (7), in which the control device compares the current measured by the current measurement circuit with the predetermined current value stored by a first motor (7) so that it is determined when the movement of at least one first component movable by the first motor is stopped when the at least first component rests against a surface； and the control device moves one or more additional components by means of the respective one or more additional motors (7) so that each subsequent component is moved after determining that the movement of the preceding component is stopped when the preceding component rests against a surface.Una prótesis o una ortosis que comprende: una pluralidad de componentes móviles pudiendo cada componente ser movido por un respectivo motor (7)； y un dispositivo de control que controla el movimiento de los componentes móviles y almacena valores de corriente predeterminados para los respectivos motores (7), caracterizada por que la prótesis o la ortosis comprende además un circuito de medida de corriente que mide la corriente obtenida por los respectivos motores (7), en la que el dispositivo de control compara la corriente medida por el circuito de medida de corriente con el valor de corriente predeterminado almacenado por un primer motor (7) de manera que se determina cuándo el movimiento de al menos un primer componente movible por el primer motor es detenido cuando el al menos primer componente se apoya contra una superficie； y el dispositivo de control mueve uno o más componentes adicionales por medio del respectivo u
